We use it, among other things, to bond with each other (how are you?), explain ourselves (I’m not angry, I’m just disappointed), convince others (Tosh.0 is the best show ever), or motivate people to perform an action (close the window, I’m freezing). In order for communication to fulfill these purposes, however, we need to be able to establish coherence between the pieces of communicated information. Without coherence, it becomes very difficult, and maybe even impossible, to understand each other. The following conversation, taken from Monty Python’s Life of Brian, illustrates how easily these things can go wrong. [Brian is running from the Romans and pretends to be a prophet] BRIAN: Yes. Consider the lilies... ELSIE: Consider the lilies? BRIAN: Uh, well, the birds, then. EDDIE: What birds? BRIAN: Any birds. EDDIE: Why? BRIAN: Well, have they got jobs? ARTHUR: Who? BRIAN: The birds. EDDIE: Have the birds got jobs?! FRANK: What's the matter with him? ARTHUR: He says the birds are scrounging. BRIAN: Oh, uhh, no, the point is the birds. They do all right. Don't they? FRANK: Well, good luck to 'em. EDDIE: Yeah. They're very pretty. BRIAN: Okay, and you're much more important than they are, right? So, what are you worrying about? There you are. See? EDDIE: I'm worrying about what you have got against birds. BRIAN: I haven't got anything against the birds. Consider the lilies. ARTHUR: He's having a go at the flowers now. In this dialogue, Brian is trying to explain that people should not worry about being unemployed. After all, God takes care of the birds, so it follows that they should also be all right. However, this message does not come across because Brian’s audience fails to establish coherence at several levels 2|Chapter 1 of discourse representation. Brian starts off by saying “consider the birds”, in which he is referring to birds in general. Eddie, however, misinterprets “the birds” as referring to a specific set of birds in the discourse. Indeed, definite nouns can be used to refer to uniquely identifiable discourse referents (Givòn, 1978), however, this is not the case in Brian’s story. As a result, Eddie is confused (What birds?). And while Brian continues to talk about birds by asking “have they got jobs?”, Arthur fails to establish the relation between the pronoun “they” and the previously mentioned birds. Pronouns are devices that establish relations with entities in the discourse context; as such they allow speakers and listeners to establish discourse coherence. When faced with a pronoun in a text or conversation, we automatically start looking for the antecedent to which it relates. Clearly, Arthur is not able to do so, which is why he has no idea what Brian is talking about (Who?). Both examples are instances of referential coherence (or incoherence in these cases), which is about the relations between linguistic units and the discourse entities to which they refer. Crucially, Brian’s audience also fails to establish coherence at higher levels of discourse representation. First, they fail to understand how exactly the different clauses are related, as they do not get the contrastive relation between “the birds don’t have jobs” and “the birds are doing alright”. In addition, they are fully oblivious to the underlying message that Brian is trying to convey. The listeners have to infer that Brian uses the birds as an example to point out that people should not worry about their lives. But in order to get this message, we need to be able to follow Brian’s reasoning; that one thing follows from the other. The audience, however, fails to do so, which is why they do not get why Brian is fussing about birds in the first place. What these examples illustrate, is that discourse comprehension is often only in part about what we explicitly tell each other. In everyday communication, we constantly need to infer all kinds of information in order to establish a coherent picture. This process of adding information is referred to as inferencing (Singer, 1990; Haviland & Clark, 1974), and is driven by world knowledge and expectations on the basis of the discourse context. There are many different types of inferences that people make, such as referential inferences, as described above, elaborative inferences, which elaborate on the discourse so far, and bridging inferences, which establish the relations between discourse segments. Even though there are many specific conditions under which readers generate inferences (e.g., Balota, Flores d'Arcais, & Rayner, 1990; Graesser & Bower, 1990; Noordman, Vonk, & Kempff, 1992; McKoon & Ratcliff, 1992; Singer, Graesser, & Trabasso, 1994; Vonk & Noordman, 1990), causal bridging inferences, or causal knowledge-based inferences (Millis, Golding, & Barker, 1995, p.30), are claimed to be essential for text comprehension (e.g. Black & Bower, 1980; Graesser & Clark, 1985; Keenan, Baillet, & Introduction|3 Brown,1984; Trabasso & van den Broek, 1985 ). And there is experimental evidence that such inferences are generated online during comprehension (e.g. Graesser, Singer, & Trabasso, 1994; Keenan et al., 1984; Meyers, Shinjo, & Duffy, 1987). An example of a causal bridging inference is provided in (1). First the reader has to infer that my neighbor fell, which is not explicitly stated in this discourse. In addition, the reader needs to infer that the fall was the actual cause of the broken arm. (1) (2) My neighbor broke his arm. He tripped over his shoelace. My neighbor broke his arm because he tripped over his shoelace. Even if the causal relation is made explicit, as in (2), the reader still has to generate these inferences in order to fully understand the relation between the two clauses. Such relations are known as coherence relations (cf. Hobbs, 1979; Kehler, 2002; Sanders, Spooren, & Noordman, 1992) or rhetorical relations (Mann & Thompson, 1988; Taboada & Mann, 2006). In the current dissertation we are mainly interested in this type of coherence. More specifically, we will focus on causal relations that are established between two clauses. A defining characteristic of coherence relations is that the interpretation of the combined segments provides more information than the sum of the segments taken in isolation (Sanders, Spooren, & Noordman, 1992, 1993). Examples (1) and (2) illustrate a causal coherence relation. Other types of coherence relations are additive (3a), and adversative (3b) relations. (3) a. My bike got stolen and I just dropped my cell phone in the toilet. b. He wasn’t that good looking, but I went out with him anyway. These relations can, but need not, be made explicit by linguistic markers such as connectives. Connectives are single word items, or fixed word combinations, that are used to link two clauses, and belong to the grammatical class of conjunctions (because, and, however) or adverbial expressions (hence) (Pander Maat & Sanders, 2006). Other signals that help establish coherence are lexical cue phrases and signaling phrases (for that reason, in addition, on the other hand). Although these different markers vary with respect to the grammatical categories to which they belong, they all have a very similar function when it comes to establishing discourse coherence; they provide explicit information about the relation between two or more clauses. Note that these relations are not limited to consecutive clauses (4). 4|Chapter 1 (4) Neil Armstrong, that spaceman, he went to the moon, but he ain’t been back. So It can’t have been that good.1 Since the presence of a coherence marker is not a prerequisite for establishing coherence relations (compare (1) and (2)), the dominant view on coherence phenomena is that the connectedness of discourse is a property of the cognitive representation of the discourse, rather than of the discourse itself (Graesser, McNamara & Louwerse, 2003; Sanders et al., 1992). At the same time, coherence markers have been demonstrated to help readers construct the representation of the unfolding discourse. Causal connectives have been found to increase causal inference generation (Caron, Micko, and Thüring, 1988; Millis, Golding and Barker, 1995)2. In addition, results from online processing studies and studies on text representation reveal that language users benefit from the presence of a coherence marker. Coherence markers are therefore conceived as explicit processing instructions3 that tell readers how one part of a text is to be related to another (e.g. Britton, 1994; Gernsbacher, 1997; Murray, 1995; Sanders & Spooren, 2007). In this dissertation we will focus on the effects of such instructions on online processing. 1.2 Coherence markers and representation In order to better understand the function of coherence markers in online processing, we will first discuss the effects that these markers have on text comprehension. 1.2.1 Coherence markers improve text comprehension A number of studies have shown that overt markers of coherence relations improve the mental representation of a text. Some of these studies focus on the markers of coherence relations only, whereas so-called mixed signal studies also include other types of signals, such astopic headings, summaries, and importance cues such as ‘an essential point is’. Such signals help identify the main points of a text and are therefore also assumed to contribute to the construction of its representation. A general finding is that the presence of coherence markers leads to better recall performance (e.g. Lorch & Lorch, 1986), more complete summaries (Hyönä & Lorch, 2004), faster and more accurate responses to comprehension questions (Degand & Sanders, 2002; Adapted quote from Karl Pilkington. Other studies found that causal connectives did not increase inference generation (Maury & Teisserenc, 2005; Millis, Graesser, & Haberlandt, 1993) 3 Note that the term processing instructions is used to refer to the information provided about the discourse structure and not about the syntactic analysis of the input. 1 2 Introduction|5 Millis & Just, 1994), faster responses on verification tasks (Sanders & Noordman, 2000), better performance in sorting tasks (McNamara, Kintsch, Songer, & Kintsch, 1996; Sanders, Land, & Mulder, 2007) and a higher overall quality of recalled information (Loman & Mayer, 1983; Meyer, Brandt, & Bluth, 1980). The work by Degand and Sanders (2002) is one example of a study that focuses on the markers of coherence relations only. The authors tested the effects of Dutch causal connectives (want, omdat, doordat, which can all be translated by because), and cue phrases (the reason was, a consequence of this was) on the comprehension of expository texts in both L1 and L2 of Dutch- versus French-speaking readers. For both groups, overt marking was found to lead to higher accuracy on comprehension questions. Interestingly, these questions did not only concern the causal relations but other aspects of the text as well. Other studies, however, report mixed results about the effects of coherence markers on text representation. For example, Spyridakis and Standal (1987) conducted an experiment in which they tested the effects of different types of signals such as connectives, preview sentences, and headings, on the comprehension of technical expository passages. The authors found only a limited effect of marking on text comprehension as measured by inference scores and recall measures. Post-hoc analyses revealed that coherence markers increased text comprehension only for difficult texts. Some studies report no recall advantage for sentence pairs linked by a connective (Golding, Millis, Hausel, & Sego, 1995; Murray, 1995) or cue phrase (Sanders & Noordman, 2000), while others report superior cued recall performance for causal but not for additive connectives (Caron, Micko, & Thüring, 1988; Maury & Teisserenc, 2005; Millis, Golding, & Barker, 1995; Millis & Magliano, 1999). Millis, Graesser, and Haberlandt (1993) even report worse recall performance for expository texts with coherence markers (temporal, causal, and intentional) compared to the unmarked condition. A number of factors could explain these diverging results (see also Degand & Sanders, 2002; Sanders & Noordman, 2000, for more details). For example, it could be related to the differences between various types of coherence markers (additive, contrastive, causal) and signals of discourse structure, the operationalization of text comprehension (free recall versus comprehension questions), or reader characteristics. An example of the latter type is that readers with a high degree of knowledge about a given text topic do not benefit from textual signals in the way that low-knowledge readers do (but see Roebben & Bestgen, 2006). McNamara and Kintsch (1996), McNamara et al. (1996) and Kamalski, Lentz, Sanders, and Zwaan (2008) found that high-knowledge readers benefit more from an implicit version of a text. For these readers, explicit marking of local and global coherence results in an inferior representation of the text. 6|Chapter 1 Similar results are reported in studies on topic headings. More advanced readers do not seem to benefit from headings as much, presumably because they already apply systematic topic-processing strategies and do not rely on the instructions provided by these signals (Meyer, Brandt, & Bluth, 1980; Sanchez, Lorch, & Lorch, 2001). Also, other factors such as readers’ goals (Noordman, Vonk, & Kempff, 1992) verbal ability (Meyer, Young, & Bartlett, 1989) and text genre (Kamalski et al., 2008) modulate the possible facilitation effects associated with markers of discourse structure. 1.2.2 Levels of representation So far, we have discussed the various effects of coherence markers on the discourse representation. However, when talking about such representation, discourse psychologists generally agree that it is not a one-dimensional concept. Instead, there is a consensus that a text can be represented at three different levels of representation: a surface form of the text (surface code), a network of idea units, or propositions, mentioned in the text (textbase), and a mental model of the situation (situation model) (Fletcher, 1994; Fletcher & Chrysler, 1990; Graesser, Millis, & Zwaan, 1997; Kintsch, 1998; Zwaan & Radvansky, 1998). The main difference between the textbase and situation model level is that the latter also includes inferences (cf. Kintsch, 1998). The causal structure of a text is assumed to be one of the major dimensions of the situation model (Graesser et al., 1997; Zwaan & Radvansky, 1998). However, given that causal relations can be explicitly marked by coherence markers, discourse researchers have wondered at which level of representation such relations should be represented. Noordman and Vonk (1998) argue that coherence relations that are marked by explicit coherence markers are represented at both the text base and situation model level of representation. Mulder and Sanders (2012), however, found no evidence for a separate textbased representation of causal relations that are explicitly marked by a connective. In their Dutch experiment, participants read non-volitional causal relations that were marked by a causal connective, such as (5a), that served as a model sentence. Afterwards they were presented with relations that varied at the surface code level (5b), the text base level (5c), or at the level of the situation model (5d), and they were asked to judge whether they had read that particular sentence. (5) a. Bashir moest in het ziekenhuis worden opgenomen, omdat zijn hartklachten ernstig waren toegenomen. Bashir had to be hospitalized because his heart problems had increased severely. b. Bashir moest in het ziekenhuis worden opgenomen, doordat zijn hartklachten ernstig waren toegenomen. Introduction|7 Bashir had to be hospitalized [because – paraphrase] his heart problems had increased severely. c. Bashir moest in het ziekenhuis worden opgenomen, nadat zijn hartklachten ernstig waren toegenomen. Bashir had to be hospitalized after his heart problems had increased severely. d. Bashir moest in het ziekenhuis worden opgenomen, en zijn hartklachten waren ernstig toegenomen. Bashir had to be hospitalized and his heart problems had increased severely. As in the model sentence (5a), (5b) expresses a backward causal relation, yet it is marked by a different causal connective that can be used to express the same relation. Therefore, this condition only differs from the model with respect to its surface code. In (5c), the relation is marked by the temporal connective after, and thus differs from the model at both the surface code and the text base level of representation. Because temporal relations systematically allow for a causal relation between two events, the situation model is still compatible with the model sentence. Finally, condition (5d) differs from the model at all levels of representation. The additive connective also allows for a causal interpretation, however it only allows for a forward causal relation in which the cause precedes the effect, which is not compatible with the situation model representation of the model sentence. The results revealed that participants could not distinguish between causal relations that differ with respect to the surface code of the causal connective, or its textbase representation. Only the changes at the level of the situation model were detected. These results suggest that explicit causal relations are represented at the situation model only. Given that causal relations do not require overt coherence markers, it seems obvious that these relations are not simply a property of the superficial surface code level of representation of a text. Whether they are represented at the situation model only, or – in specific cases – also at the textbase level, is not the focus of this dissertation. Our main concern is the influence of coherence markers on discourse processing. We will, however, return to this issue in the final chapter, where we will relate our findings to the discussion on the representation of coherence relations. 1.3 Coherence markers and online discourse processing The studies discussed in the previous section illustrate that in many cases the presence of coherence markers affects the cognitive representation of a text, as measured after reading. Another question is how these effects relate to the dynamic process of on-line discourse processing. Are coherence markers to be conceived as cues that guide online processing? Or do they affect the representation of a text only after it has been processed, even during the retrieval of that representation? 8|Chapter 1 1.3.1 Processing studies A growing number of experimental studies have investigated the effects of coherence markers on online processing. By now, it has become evident that such markers indeed have an immediate influence on the interpretation of the unfolding sentence (e.g. Kehler, Kertz, Rohde & Elman, 2008; Koornneef & Sanders, to appear). In a typical experimental set-up, sentence pairs are presented with and without a coherence marker, and reading times for the second sentence are compared. The methods that have been used vary from self-paced reading, in which sentences are cut up in segments and participants pace through a text by pressing a button, to eye-tracking, in which participants’ eye-movements are registered while they read the text. Some studies have looked at the reading times of the entire second clause, whereas others have analyzed shorter text segments in order to be more precise about the locus of effects. Many of these studies have reported faster processing times for information preceded by a coherence marker (Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Kamalski et al., 2008; Millis, Golding, & Barker, 1995; Millis & Just, 1994; Noordman & Vonk, 1997; Sanders & Noordman, 2000). In a classical study, Haberlandt (1982) manipulated short narratives in which target sentences were embedded that were either causal or contrastive continuations of the story (see (6) for an example of the adversative condition). This target sentence was preceded by an appropriate causal (therefore, so) or adversative (however, but) connective, and reading times were compared to implicit versions of the texts. (6) The jet had just taken off. The left engine caught fire. The passengers were terrified. They thought the plane would crash. However, the pilot made a safe landing. It was found that the final clause was read faster when it was preceded by a connective. This effect was strongest at the first words of the second clause (the pilot). Haberlandt concluded that connectives facilitate reading comprehension because they make the semantic relation between two clauses explicit (p. 243). Such speeding up effects are not limited to connectives per se; similar effects have been observed when coherence relations are marked by means of signaling devices such as the problem is and another aspect might be (Sanders & Noordman, 2000). Furthermore, while most experiments focus on high skilled readers, recent experiments by Cain and Nash (2011) illustrate that the presence of coherence markers also leads to faster reading times in young readers of 8 and 10 years old. A general issue that arises from these studies concerns the time course of effects. In addition to an initial speeding up effect, some studies also report longer processing times at the final words of a relation marked by a causal Introduction|9 connective (Cozijn, 2000; Cozijn, Noordman, & Vonk, 2011; Millis & Just, 1994). (We will discuss these effects, and their interpretation, in more detail in Chapter 2). Other studies have investigated the effects of different types of connectives. These studies report a processing facilitation for backward, but not for forward causal connectives (because versus so) (Maury & Teisserenc, 2005), or for adversative, but not for additive or forward causal connectives (Golding, Millis, Hauselt, & Sego, 1995; Murray, 1995, 1997). For example, in two self-paced reading experiments, Murray (1995) tested the different effects of additive, forward causal and adversative connectives on the processing of two sentence narratives as in (7). (7) a. Additive Rudy and Tom avoided each other on the bus to the amusement park. Moreover / Furthermore / Also / And They didn’t speak to one another for the rest of the day. b. Causal Rudy and Tom fought with each other on the bus to the amusement park. Therefore / So / Thus / Consequently They didn’t speak to one another for the rest of the day. c. Adversative Rudy and Tom laughed with each other on the bus to the amusement park. Yet / Nevertheless / However / But They didn’t speak to one another for the rest of the day. Murray reported faster processing times for the second clause of the adversative relation when it was marked by an adversative connective compared to the implicit version. Causal and additive connectives, however, did not lead to such facilitation effects. Golding et al. (1995) obtained similar results. Yet, Murray’s study immediately illustrates why it is difficult to draw clear conclusions about the processing effects of different connectives. One problem that arises in many experiments concerns the materials. In a typical set-up, the processing of unmarked relations is compared to marked versions of the same relations. The idea is that, by doing so, researchers are able to measure reading times and eye-movements in response to identical target information in both conditions. However, too often those conditions are not truly comparable, because the relation expressed by the connective is different from the implicit relation. For example, the facilitation effect of adversative connectives in Murray’s design is easily explained by a confounding factor. Without the adversative connective it is very difficult to establish any coherence relation between the two segments (7c). Indeed, the mean reading times for the implicit version of these relations is much higher compared to the other conditions. It is, therefore, not surprising that the adversative connective leads to the largest processing benefit. In addition, using various types of additive, causal or adversative connectives in a single 10|Chapter 1 design, as in Murray’s study, may also be problematic because there may be other differences between those connectives, with respect to their semanticpragmatic properties (Knott & Dale, 1994; Knott & Sanders, 1998; Martin, 1992) that could influence the processing data. For instance, so is different from consequently because it allows for relations that have different conceptual orders (Noordman & De Blijzer, 2000). The connectives consequently and so can both be used to express causal relations that are based on a real-world order of causes and effects, such as (8): the effect presented in the second discourse segment (from now on referred to as S2) is derived from the cause presented in the first discourse segment (from now on referred to as S1). (8) John worked hard, consequently / so he passed the exam. So, however, can also be used in causal relations in which this conceptual order is inversed, and the cause is derived from the effect. In (9) for example, passing an exam is taken as indication of hard work. (9) John passed the exam, so he worked hard. This means that the connective so is less specific with respect to the conceptual order of events of the relation it marks. Since it is unclear whether such differences affect online processing, it is unwise to pool reading times over different types of connectives, even if they belong to the same class (causal, additive or adversative). A more practical limitation of the on-line study of coherence markers is the way in which reading times are measured. Some studies report total reading times for the entire second clause (Golding et al., 1995; Murray, 1995, 1997), whereas others cut up the second sentence in order to be more precise about the time course of effects (Cozijn, 2000; Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Maury & Teisserenc, 2005; Millis & Just, 1994; Sanders & Noordman, 2000). If causal (and possibly also other) connectives lead to an initial speeding up effect, and to a slow down at the end of the relation, analyzing total reading times for the entire second clause will probably not reveal any effects. Nevertheless, it is likely that not all connectives affect on-line processing in the same way. For example, the presence of an adversative connective is often a prerequisite for establishing any relation between two clauses. See, for example, the adversative relation used by Haberlandt (1982), here repeated in (10). (10) The jet had just taken off. The left engine caught fire. The passengers were terrified. They thought the plane would crash. The pilot made a safe landing. Introduction|11 Without the adversative connective it is very difficult to establish any relation between S1 and S2. Therefore it makes sense that readers benefit more from the presence of an adversative connective compared to connectives that can be omitted more easily, such as additive connectives. Clearly, more research is required in order to fully understand the mechanisms underlying the processing of different types of coherence markers. The current dissertation provides new information about such mechanisms, as we focus on subtle semantic-pragmatic differences between causal connectives, and how these affect online processing. 1.3.2 Theoretical explanations of processing effects The observation that connectives speed up the processing of the immediately following words is generally interpreted as reflecting cognitive processes related to integration. Integration refers to the construction of the two text segments into a single representation. There are, however, different ways in which this process is characterized and how it could be reflected in online processing. One explanation is that connectives function as cues that signal to the reader that the default discourse interpretation has to be overwritten. Murray (1997), for example, proposes an explanation in terms of the “principle of continuity” (Segal, Duchan, & Scott, 1991, p.32). According to this principle, readers by default assume that continuity is maintained, hence interpreting subsequent sentences in a continuous fashion. If continuity is violated, it should be marked in some way (Bestgen & Costermans, 1994). This hypothesis is supported by experimental evidence that shows that unmarked discontinuous discourses lead to longer processing times compared to continuous discourses. Crucially, this difference in processing time is canceled out by explicit markers of discontinuity (Bestgen & Vonk, 2000). Murray proposes that certain logical connectives serve as explicit markers for discontinuity. Adversative connectives, such as however, signal discontinuity because they indicate that the anticipated causal relation did not occur. Backward causal connectives, such as because, also signal discontinuity because they mark a nonlinear order of events, that is effect-cause instead of cause-effect. The presence of these markers is therefore assumed to lead to a larger processing benefit compared to markers that signal continuity, because the unmarked relations are more difficult. This account is compatible with Murray’s findings that adversative connectives lead to a larger processing benefit compared to additive and (forward) causal connectives, as becomes apparent from the total reading times of S2. Note, however, that effects of discontinuity (in implicit relations) are likely to arise towards the end of the second sentence when the proposition is available anyway. After all, readers can only know whether a sentence 12|Chapter 1 follows the discourse in a continuous fashion when they know the propositional content of that sentence. Because Murray measured total reading times of the entire second clause, his data shed insufficient light on the immediate processing effects of the different connectives. Another theoretical explanation for the processing facilitation effect of coherence markers is that the presence of these markers limits the range of possible interpretations. Having read S1, the reader does not need to take into account all the possible relations that could be constructed between two text segments, which reduces the processing load. This interpretation dates back at least to Hirsch (1977, p.128) who proposes that connectives contribute to the integration of successive clauses by “forecasting” the relation between them. He suggests that because connectives reduce uncertainty (about the relation between two clauses), they are assumed to speed up the processing of clauses. Similar accounts surface in Britton, Glynn, Meyer, and Penland (1982), who argue that the presence of a connective reduces the number of inferences the reader must make, in Haberlandt (1982) and in Murray (1995). Haberlandt (1982) proposes that connectives facilitate reading processes because they guide the reader’s expectations about the coherence relation between S1 and S2. In the absence of a connective, readers have to make “compensatory inferences” (p.243) which increases the processing load. According to Murray (1995), the meaning of a connective limits the range of possible relations that can be constructed between the two clauses. Combined with the first clause, a connective activates an “expectancy of the content of the post-connective sentence” (p.120). The more constraining the connective meaning, the larger the processing benefit. This explanation fits Murray’s findings, as discussed earlier, that adversative connectives (which are highly constraining) lead to a larger processing facilitation than other types of connectives. Proposals such as the ones we just described assume that connectives lead to faster processing times because they reduce the generation of irrelevant interpretations. However, it might just as well be the case that these faster processing times are not caused by the fact that connectives reduce the number of possible interpretations, but by the fact that a single representation is constructed, which is facilitated by the presence of the connective. This type of explanation surfaces in studies that focus on the actual integration process (Cozijn, Noordman, & Vonk, 2011; Millis & Just, 1994). Cozijn et al. for example, argue that because a connective makes the exact type of coherence relation between two text segments explicit, readers can immediately start to integrate the second clause into the sentence representation. Introduction|13 So far, this section provided an overview of the different explanations that have been proposed to account for the immediate processing facilitation effect associated with connectives. What these approaches have in common is that the meaning of a connective is assumed to facilitate the interpretation of the relation between two pieces of text. As such, connectives are considered to contribute to the integration of these two pieces into a single representation. That connectives indeed have a special integrative function is corroborated by recent neurolinguistic evidence that suggests that connectives trigger specific cognitive processes related to interclausal integration (Brehm, 2005). Therefore, connectives can be conceived as processing instructions. Not only do they have an important function in the construction of the syntactic structure, for example by marking coordinate or subordinate clauses, they also provide discourse information about the relations between two text segments. In this dissertation we will further investigate the nature of such instructions. To be more specific, we will investigate whether these instructions also convey information about the specific subtype of causal relation the connective marks. 1.4 Causality and subjectivity in discourse processing The studies described in the previous sections provide an overview of the research concerned with coherence markers, as well as some issues that are relevant in the study of discourse processing and comprehension. So far, we have seen that there is substantial evidence that (at least certain types of) connectives and cue phrases speed up the processing of the subsequent information. However, these processing data alone do not tell us anything about how such effects should be interpreted. In combination with the results from comprehension studies discussed in section 2.1, we can conclude that despite these faster reading times, the presence of coherence markers does not lead to an inferior representation of information. If anything, they actually improve text comprehension. Taken together, these studies provide valuable insights in the processing and representation of coherence markers: such markers facilitate the construction of a coherent representation, which leads to faster processing times and a stronger representation of the text. However, we also saw that not all studies report the same benefits for all coherence markers. As such, it is difficult to draw clear conclusions that generalize over all signals and relations. The fact that mixed signal studies manipulate many different types of signals at the same time is problematic. For example, causal, additive, and temporal connectives are manipulated in addition to all kinds of other structural signals. Moreover, it is difficult to compare results across studies because experiments differ with respect to their materials and the methods that were used, as discussed in section 3.1. It is not surprising then that these studies report diverging results. In the current dissertation 14|Chapter 1 we will therefore focus on one specific type of coherence relation and its markers: causal relations and causal connectives. Among the various types of coherence relations, causality has a special status. Causality is a fundamental cognitive principle that plays an important role in the construction of a coherent representation (Graesser, Singer, & Trabasso, 1994; Singer, Graesser, & Trabasso, 1994). Indeed, experimental studies suggest a processing and representational advantage for causal compared to other types of coherence relations (see Chapter 2). In this dissertation, however, we will not focus on causality in general, but on various subtypes of causal relations that systematically differ from each other. Studies of coherence relations have identified a distinction between subjective and objective causal relations. Objective causal relations express causality between events in the real world (11a), whereas subjective causal relations express the relations between the speaker’s conclusions on the basis of events in the world (11b) (see Chapter 2 for more details). Note that this distinction is not limited to so-called backward causal relations, but also surfaces in so-called forward causal relations (12a and b). The difference between forward and backward causal relations concerns the order of events as they are presented in the text. Forward causal relations have a linear order between events in which causes precede effects. Starting from a basic causal operation in which tripping leads to breaking something, in the sequence S1 connective S2, S1 corresponds to the antecedent (P) and S2 corresponds to the consequent. In backward causal relations, this order is reversed and effects precede causes in the text; S1 corresponds to Q, and S2 corresponds to P (Sanders et al.,1992). (11) a. My neighbour broke his arm because he tripped over his shoelace. b. My neighbour was being an idiot again because he tripped over his shoelace and broke his arm. (12) a. My neighbour tripped over his shoelace. As a result he broke his arm. b. My neighbour tripped over his shoelace and broke his arm so he was being an idiot again. The English connective because can be used to express both subjective and objective causal relations, as example (9) illustrates (e.g. CouperKuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990). However, for some languages, such as Dutch, it has been observed that these various relations are systematically expressed by different connectives. Linguistic studies of connectives in language use have therefore investigated whether there is a direct relation between these connectives and the different types of causal relations they typically express. With respect to Dutch backward causal relations, the connective want is a Introduction|15 prototypical marker of subjective causal relations, whereas omdat is a prototypical marker of objective causal relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009, 2012; Verhagen, 2005). Similarly, in forward causal relations dus typically expresses subjective relations, whereas daarom is typically used in objective relations (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, 2005; Verhagen, 2005), see Table 1. Table 1. Summary of the differences between the Dutch causal connectives daarom versus dus and omdat versus want. P and Q stand for antecedent and consequent respectively. S1 corresponds to the first discourse segment and S2 corresponds to the second discourse segment. Volitional Objective Subjective Direction Daarom (that’s why) Dus (so) Forward: S1=P, S2=Q Omdat (because) Want (because/since) Backward: S1=Q, S2=P The central question in this dissertation is whether the difference between subjective and objective causal connectives is relevant in online processing. Or, in other words, assuming that causal connectives are processing instructions, do these instructions include specific information about the exact type of causal relation that needs to be constructed? The reason why this information may be relevant is that subjective causal relations are assumed to be more complex than objective causal relations (Noordman & De Blijzer, 2000; Sanders et al., 1992; Traxler, Sanford, Aked, & Moxey, 1997). Evidence in favor of this hypothesis comes from processing studies in Dutch and English which reveal that readers need more time to process subjective (13b) compared to objective (13a) causal relations (Noordman & De Blijzer, 2000; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997). (13) a. My neighbor went to the hospital because he tripped over his shoelace and broke his arm. b. My neighbour was being an idiot again because he tripped over his shoelace and broke his arm. We investigate this issue in the nine eye-tracking experiments presented throughout this dissertation. Eye-tracking allows for a precise registration of the reader’s eye-movements when reading a text, and is able to capture early cognitive processes (such as lexical access) as well as later cognitive processes (such as reanalysis). As a result, this method is particularly suitable for studying the effects of causal connectives on the 16|Chapter 1 dynamic process of discourse comprehension. At the beginning of this section we have underlined the importance of combining online processing data with offline representation data. The current dissertation, however, will mainly focus on online processing data. The main reason why we did not include offline representation tasks is that such tasks reveal the purpose of the experiment and can therefore change the participant’s reading strategies. Note, however, that the processing effects described in this dissertation are not interpreted in isolation. Combined with insights from corpus-based studies and earlier processing data, our results provide valuable information about the cognitive processes involved in the processing of different types of causal connectives. The main issues and research questions addressed in this dissertation will be discussed in the following section. 1.5 Chapter overview and research questions In Chapter 2 we first present a theoretical background after which we explore whether the notion of subjectivity could play a role in the processing of causal connectives. We start out by focusing on the Dutch causal connective want. Even though want is most frequently used in subjective causal relations, this connective can be used in all relational contexts in which because occurs. We investigate whether this means that want and because are actually very similar with respect to their semantic-pragmatic properties. If so, they should also have the same effect on the processing of subjective and objective causal relations, which gives rise to the following research question: RQ1 Is the Dutch connective want comparable to English because with respect to its processing instructions? This question is tested in an eye-tracking experiment in which we use a Dutch version of the items from Traxler, Bybee, and Pickering (1997). In the English experiment it was found that subjective causals with because led to longer processing times compared to objective causals with because. This effect arose right before the end of the second clause. We find that when want is used to mark both subjective and objective causal relations in Dutch, there are no processing differences between these two types of causal relations. This outcome suggests that want and because have in fact a different influence on the processing of causal relations. In Chapter 3 we investigate whether this difference could be related to the degree of subjectivity that is encoded in want. We present three eyetracking experiments in which we use the materials from Chapter 2. But instead of using want in both conditions, we use the prototypically objective connective omdat to mark the objective relations. The main research question in this chapter is: Introduction|17 RQ2 Is the distinction between subjective and objective causal connectives, as distinguished in corpus-based studies on the semantic-pragmatic characteristics of connectives, relevant in online processing? And if so, what is the time course of this effect? Results reveal that subjective causal relations with want lead to longer processing times compared to objective causal relations with omdat. However, where in English this effect arises just before the end of the second clause, in our Dutch experiment, it surfaces immediate at and after the connective want (Experiment 1). In addition, when the reader is explicitly cued about the status of S1 as a claim or conclusion by means of the mental state predicate according to John, the delay in processing times for subjective compared to objective causal relations is canceled out (Experiment 2). These results show that the source of the processing difference between want and omdat is similar to the source of the processing difference between English subjective and objective causal relations (Traxler, Sandford, Aked, & Moxey, 1997), and not a result of lexical differences between want and omdat. We therefore propose that the longer processing times induced by want are related to the representation of S1 as someone’s reasoning, be it from the speaker, author, or any third person character in the discourse, rather than an actual event in the world. In a third experiment we observe that the processing pattern of want versus omdat is unrelated to the actual content of the combined text segments. In addition, this experiment shows that readers are garden pathed when omdat is used to mark a relation that is incompatible with an objective CONSEQUENCE-CAUSE interpretation. On the basis of these results we conclude that the Dutch connectives want and omdat provide instructions about the type of causal relation that needs to be constructed: want instructs the reader to construct a subjective relation whereas omdat instructs the reader to construct an objective relation. Crucially, these instructions immediately affect online processing. In Chapter 4 we investigate the processing complexity of subjective causal relations from a mental space perspective. The difference between subjective and objective causal relations has been characterized in terms of different mental space configurations (Sanders, Sanders, & Sweetser, 2009, 2012). In this chapter we investigate how this difference could explain the online processing complexity of subjective causal relations. The central question in this chapter is: RQ3 Is the processing complexity of subjectivity related to processes involved in the setup of the mental space of the thinking subject? 18|Chapter 1 We present two eye-tracking experiments in which we manipulated oneparagraph long news texts with embedded subjective and objective causal relations marked by want and omdat respectively. Subjective contexts are created by adding space builders in the form of evaluative adverbs and adjectives, such as terribly, horrible and luckily, to the context preceding the causal relations. These markers reveal that the author of the text is emotionally involved in the matters under discussion. An offline judgment task shows that readers recognise the author’s involvement in the texts, which shows that our manipulation of subjectivity is successful. In addition, the eye-movement data reveal that the presence of evaluative markers increases the processing times of subsequent information. However, these markers have no influence on the processing asymmetry between want and omdat. Taken together, the results suggest that the asymmetry between want and omdat is not explained by the necessity of setting up a new mental space. In Experiment 2 we place the same non-sentence modifying evaluative adverbs within S1 of the causal relations. Again, we find no effect of space builders on the processing difference between want and omdat. These results suggest that markers of subjectivity that do not modify the status of S1 as a whole as subjective do not have the ability to cancel out the processing complexity of subjective causal relations. We propose that the processing complexity of subjective causal relations may be explained by the placement of S1 as a whole within the mental space of the relevant thinking subject be it the speaker or author, or any third person character whose reasoning is presented. In Chapter 5 we focus on why this operation should lead to longer processing times. But first we verify whether the processing effects reported in Chapters 3 and 4 can be explained in terms of a reanalysis of S1 as a claim or conclusion, as proposed by Traxler, Sanford, Aked, & Moxey (1997), or whether its processing and representation is inherently complex. RQ4 Is the processing complexity of subjective compared to objective causal relations caused by a reanalysis of S1 as a claim? Experiment 1 reveals that the same processing asymmetry surfaces with forward subjective and objective causal connectives (dus versus daarom). Given that in forward subjective relations with dus the claim follows the connective, the complexity of subjective causal relations cannot be explained by a reanalysis of already processed information as a claim. Next we investigate what does explain the inherent complexity of subjective causal relations and connectives: Introduction|19 RQ5 Can we distinguish between reasoning and speaker involvement in order to explain the inherent processing complexity of subjective compared to objective causal relations? In Experiment 2 we investigate whether the inherent complexity of subjective causal relations is related to reasoning processes. In order to test this, we compare the processing of dus to the inferential evidential adverb blijkbaar, which also marks reasoning. We find that blijkbaar does not lead to a a disadvantage in processing times compared to daarom, as reported for dus. In Experiment 3 we explore whether the processing difference between dus and blijkbaar could be related to differences in terms of speaker involvement by including the epistemic modal adverb waarschijnlijk. We propose that dus encodes a high degree of speaker involvement whereas blijkbaar encodes a low degree of speaker involvement. Waarschijnlijk takes up an intermediate position. The online processing data parallel this division along the lines of speaker involvement. In Chapter 6 we summarize the main findings from each chapter. We return to issues raised in this first chapter, propose suggestions for future research and discuss the implications of our results for the study of discourse processing. 1.6 Reading guide The chapters of this dissertation are written as individual papers; Chapter 3 has already been accepted for publication in the international journal Language and Cognitive Processes (Canestrelli, Mak, & Sanders, 2012). Parts of the introduction and Chapter 2 have been published as a chapter in Handbook of Cognitive Pragmatics (Sanders & Canestrelli, 2012). Other chapters will soon be submitted to other journals4. As a result there is some overlap in the method sections and the literature overviews provided in several chapters. The advantage to the reader is that each chapter can be read on its own. 4 Preliminary versions of various chapters have been presented at conferences such as Architectures and Mechanisms for Language Processing (Barcelona, 2009), Society for Text & Discourse (Rotterdam, 2009; Chicago, 2010), and Multidisciplinary perspectives on Signalling Text Organisation (Moissac, 2010). Chapter 2 Causal connectives as processing instructions 2.1 Introduction Discourse comprehension relies on the ability to construct a mental representation of the communicated information. A crucial property of this representation is that it is coherent (e.g. Gernsbacher & Givòn, 1995). One form of coherence is relational coherence, which is concerned with the relations between two or more discourse segments such as sentences or clauses. These relations are known as coherence relations (cf. Hobbs, 1979; Kehler, 2002; Sanders, Spooren, & Noordman, 1992) or rhetorical relations (Mann & Thompson, 1988; Taboada & Mann, 2006). Among the different types of coherence relations, causal relations have a special status. Causality is a fundamental cognitive principle that plays an important role in human reasoning and perception, and it is central to the construction of a coherent discourse representation (Graesser, Singer, & Trabasso, 1994; Singer, Graesser, & Trabasso, 1994). Moreover, causally related events in short narratives are recalled more easily (Black & Bern, 1981; Bradshaw & Anderson, 1982; Sanders & Noordman, 2000; Trabasso & Sperry, 1985; Trabasso & Van den Broek, 1985) and processed faster (Haberlandt & Bingham, 1978; Keenan, Baillet, & Brown, 1984; Meyers, Shinjo, & Duffy, 1987; Sanders & Noordman, 2000) than non-causally related events. These findings illustrate that causal relations are encoded faster and retrieved better compared to other types of coherence relations, which suggests a strong processing and representational advantage. If causality is such a fundamental concept, it may be expected that the linguistic markers of causality also play an important role in the processing and representation of a text. Even though explicit linguistic marking is not a prerequisite to establish a causal relation, see example (1a), causal relations can be made explicit by linguistic markers such as connectives (so, because, therefore) (1b) and lexical cue phrases (for that reason, that’s why). (1) a. My sister stole my shoes. I’m going to kill her! b. My sister stole my shoes so I’m going to kill her! As such, causal connectives and cue phrases serve as explicit cues that help readers and listeners to construct causal coherence in their mental representations. Indeed, as discussed in Chapter 1, language users benefit from the presence of such devices. This becomes apparent from more accurate responses to comprehension questions (Millis & Just, 1994), superior recall performance (Caron, Micko, & Thuring, 1988; Millis, Golding, & Barker, 1995), and faster processing times of subsequent information (e.g. 22|Chapter 2 Haberlandt, 1982; Millis & Just, 1994). These findings have contributed to the assumption that causal connectives provide processing instructions to readers about the discourse structure that needs to be constructed (e.g. Britton, 1994; Gernsbacher, 1997; Sanders & Spooren, 2007). In this chapter we will focus on the type of information encoded in such instructions, and how that affects online discourse processing. 2.2 Processing causal connectives Over the past decades, a number of experimental studies have reported that causal connectives (placed in between two clauses) speed up the processing of the first words of the second clause (Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Millis, Golding, & Barker, 1995; Millis & Just, 1994; Noordman & Vonk, 1997). In addition, some studies have also reported longer processing times of the final words of causal relations marked by a causal connective (Millis & Just, 1994; Cozijn, 2000; Cozijn et al., 2011)1. These findings reveal that causal connectives affect the way in which causal relations are processed. There are, however, different levels at which this influence plays a role. First, causal connectives are assumed to serve a segmentation function (Noordman & Vonk, 1997). Connectives are function words that signal the construction of a new clause (Kimball, 1973). In addition, connectives cue that this new clause is a coordinate clause or a subordinate clause. Therefore, from a syntactic point of view, causal connectives guide language processing because they provide explicit information about the syntactic structure that needs to be constructed, which influences the parsing process (Clark & Clark, 1977; Haberlandt, 1984). In addition to this syntactic information, causal connectives also provide information about the discourse structure; they signal that a causal relation exists between two text segments. In Chapter 1 we already reflected on how this type of information could lead to the observed processing facilitation effect. In this chapter we will focus on explanations in terms of interclausal integration processes. The exact interpretation of the processing effects, however, depends on the assumed function of causal connectives in processing, and the processing mechanisms underlying the construction of interclausal relations in general. This will be discussed first. A general division can be made between researchers who assume that interclausal integration is an incremental process that occurs as soon as possible (Cozijn et al., 2011; Traxler, Bybee, & Pickering, 1997), and those who argue that interclausal integration does not occur before the end of the 1 Other studies could not replicate this processing pattern (De Leeuw, Mak, & Sanders, 2008; Kamalski, Lentz, Sanders, & Zwaan, 2008; Maury & Teisserenc, 2005). Causal connectives as processing instructions|23 second clause (Just & Carpenter, 1980; Kintsch & Van Dijk, 1978; Millis & Just, 1994). Just and Carpenter (1980) specify a processing model on the basis of immediacy principles; it assumes that the interpretation of information occurs as soon as possible. With respect to the construction of interclausal relations, however, the authors argue that this occurs at the end of the second clause, during sentence wrap up. Millis and Just (1994) picked up on these ideas and further investigated how connectives influence processing mechanisms by developing the Connective Integration Model. According to this model, the integration of two clauses linked by a connective occurs after the reader has built a representation of the second clause. At this point in the sentence readers are assumed to reactivate the first clause of the relation, this process is captured in the Reactivation Hypothesis. Because the interclausal integration process is assumed to be cognitively demanding, the processing times at the end of the second clause are expected to increase. Millis and Just tested the Connective Integration Model in a word-by-word self-paced reading experiment involving causal relations marked by because (2). Reactivation of S1 was tested by measuring probe recognition times to the verb in the first clause, which was presented at the end of the second clause. (2) The elderly parents toasted their only daughter at the party [because] Jill had finally passed the exams at the prestigious university. Probe: toasted Millis and Just report that the presence of the connective leads to greater accuracy on comprehension questions, shorter answering times and faster probe recognition times. The probe recognition data were interpreted as a reflection of the reactivation of S1 induced by the connective. In addition, compared to the implicit version, the authors report faster reading times of the words following the connective, excluding the final word. This final word produced longer reading times when the connective was present compared to an implicit version of the relation, which was interpreted as a reflection of interclausal integration. The initial speeding up effect was explained by stating that in the presence of a connective, readers wait until the end of the second sentence to integrate the two clauses. Without a connective, readers may attempt to construct a meaningful relation between the two clauses, which is cognitively demanding without the help of a connective (Millis & Just, 1994, p.129). Cozijn (2000) and Cozijn et al. (2011), however, argue that interclausal integration starts as soon as the connective is processed. Cozijn (2000) studied the different functions of the Dutch connective omdat (because) in a series of eye-tracking experiments. The materials consisted of short 24|Chapter 2 expository texts with four introductory sentences followed by a target sentence (3) that was presented either with or without the connective omdat. (3) On his way to work he experienced a long delay, [because] there was a large traffic jam on the highway. Similar to the results reported by Millis and Just, Cozijn found that the presence of omdat speeds up the processing of the first two text segments of the second clause, but slows down the processing of the final words of the second clause. Following Noordman and Vonk (1997), Cozijn (2000) assumes that causal connectives have an integration function. They facilitate the immediate integration of two text segments because they explicitly indicate how the current sentence is to be integrated with the previous one. Therefore, causal connectives initially speed up the processing of the second clause of a causal relation. In addition, Cozijn argues that causal connectives trigger the inference of extra-textual information, also referred to as the ‘inference function’, which, according to Cozijn, explains the processing slow down at the final words of the relation. More recently, these functions have been further specified by Cozijn, Noordman, and Vonk (2011). They propose that causal connectives such as because trigger distinct cognitive processes that surface at different positions in the sentence. First, causal connectives trigger the “propositional integration” of two clauses, which is described as “the process by which the comprehender establishes the type of relation […] that exists between the two propositions expressed by the two clauses” (p.476). Propositional integration takes place as soon as the reader processes the connective. In addition, when processing a causal relation, the reader has to derive the underlying causal relation (if P then Q) and match it to his or her world knowledge by either checking or adding knowledge. This process is referred to as ‘world knowledge inference’. In a self-paced reading experiment (with the same materials as used by Cozijn (2000)) Cozijn et al. replicated Cozijn’s (2000) online results: an immediate speeding up effect and a slow down at the end of a causal relation with because. In addition, the authors presented inferential statements regarding the causal relations after each sentence. For example, the verification statement that followed example (4) was “A traffic jam leads to a delay”. The verification times to these statements were faster when readers had read a text including the connective because. Cozijn et al. therefore concluded that inferences on the basis of the causal relation are made online and are more accessible when a connective is present. The studies described above provide some evidence that the discourse information encoded in backward causal connectives immediately affects online processing. Other studies have investigated whether these effects Causal connectives as processing instructions|25 generalize to forward causal connectives (Murray, 1995, 1997) and to noncausal connectives, such as adversative and additive connectives (Golding, Millis, Hauselt, & Sego, 1995; Maury & Teisserenc, 2007; Murray, 1995, 1997). However, as discussed in Chapter 1, the differences between the various studies with respect to the manipulated materials and the length of the analyzed text segments (words, clauses, or sentences) make it difficult to draw any clear conclusions about the generalizability of the effects. Taken together, experimental data show that the information about the causal structure of a discourse relation encoded in causal connectives affects online processing. However, causality is not a simple one-dimensional category; there are different types of causal relations. More importantly, these different types of causal relations are assumed to differ with respect to their cognitive complexity, which becomes evident from acquisition patterns and online processing studies. 2.3 Subjectivity and processing The class of causal coherence relations has been subcategorized into causal relations that express (observable) real-world causation (4a) versus those that do not (4b). (4) a. My neighbor broke his arm because he tripped over his shoelace and fell. b. My neighbor was being an idiot because he tripped over his shoelace and fell. Note, that this distinction is not limited to backward causal relations; it also applies to forward causality (5). (5) a. My neighbor tripped over his shoelace. As a result he broke his arm. b. My neighbor tripped over his shoelace so he was being an idiot again. The distinction between these types of causal relations has been described in various theoretical frameworks. As such, different terms have been used to describe the phenomenon (see Stukker & Sanders, 2012, for a recent overview). For example, speech act theorists distinguish between ‘propositional’ or ‘semantic’ (4a and 5a) versus ‘illocutionary’ and ‘pragmatic’ (4b and 5b) relations (De Vries, 1971; Le Groupe Lambda- λ, 1975; Sanders, Spooren, & Noordman, 1992; Van Belle, 1989; Van Dijk, 1979), whereas systemic functional grammar accounts speak of ‘ideational’ or ‘internal’ (4b and 5b) versus ‘interpersonal’ and ‘external’ (4a and 5a) relations (Degand, 2001; Haliday & Hasan, 1976; Martin, 1992). Within cognitive linguistics, a three-way division between causal relations has been proposed by Sweetser (1990). On the basis of the different ways in which the connective because is used, Sweetser argues that causal connectives can be interpreted in three ‘domains of use’: the content, 26|Chapter 2 epistemic, and speech act domains. Content relations, such as (4a) and (5a) are constructed in the observable world, whereas epistemic relations (4b and 5b) hold between a premise and a conclusion in the speaker’s mind. The third domain, speech act relations, consists of relations such as (6), in which the second clause functions as the reason for uttering the speech act in the first clause. (6) Hurry up! Because SpongeBob is about to start. More recently, text and discourse theorists have described these different interpretations in terms of the degree of speaker involvement, or, following Langacker (1990), subjectivity (Degand & Pander Maat, 2003; Pander Maat & Degand 2001; Pander Maat & Sanders 2001; Verhagen, 2005). Subjectivity roughly corresponds to ‘expression of the self’ (Lyons, 1995), and arises when “properties of the speaker’s self (such as cognition, emotion, attitudes, intentions) become part of the overall meaning of the utterance” (Pit, 2007, p.58). Representing subjectivity therefore involves the speaker’s self as a reference point. On the basis of Pander Maat and Sanders (2000), Sanders and Spooren (submitted) characterize a causal relation as subjective when its interpretation requires a so-called Subject of Consciousness (SoC). This SoC is the animate entity, which can be the speaker, author, or a character in the discourse, “whose intentionality is conceptualized as the ultimate source of reasoning, evaluating, describing or acting ‘in the real-world’ ” (p.7). When this SoC is evaluating, reasoning, or concluding, the causal relation is considered to be subjective. Non-volitional causal relations such as (7a) are considered to be objective because they do not involve human intentions and therefore do not have an SoC. In volitional causal relations such as (7b), in which human intentions do play a role, the SoC is my neighbor, who decides to go to the hospital because he broke his arm. Here the SoC is performing a deliberate action, therefore this relation is also characterized as objective because the SoC is not performing a mental operation. Relations such as (7c) and (7d) are considered to be subjective, because here we are dealing with SoCs who are performing mental operations. In (7c) the SoC is the speaker, or author, whereas in (7d) this SoC is Mary. (7) a. The cup broke because it fell off the table. b. My neighbor went to the hospital because he broke his arm. c. My neighbor is an idiot because he tripped over his shoelace and fell. d. Mary thinks my neighbor is an idiot because he tripped over his shoelace and fell. Causal connectives as processing instructions|27 According to Pander Maat and Sanders (2000), the difference between subjective and objective causal relations can also be characterized by the distance between the SoC and the current speaker. Volitional objective causal relations such as (7b) involve a certain distance between the SoC and the current speaker, while the SoC in subjective causal relations is often identical to the current speaker (7c). Even though subjective relations can involve third person SoCs (7d), first person evaluations (7c) have been considered to be more subjective than third person evaluations (7d) because the first person perspective is closer to the communicative “here and now” (Sanders, Sanders, & Sweetser, 2012; Traugott, 1989, 1995). In the current study we focus on what these different perspectives have in common; they all involve a thinking subject who is reasoning or concluding, thereby taking responsibility for the causal relation expressed. In most cases this subject is the speaker or author (7c), but it can also be a third person character in the discourse (7d). For the sake of brevity we will refer to the speaker in our discussions on subjectivity and speaker involvement, unless it is of particular relevance to specify the thinking subject whose reasoning we are dealing with. Note that the notion of subjectivity also shows up in research in the domain of modals and (modal) evidentials (e.g. Garrett, 2001; Koring, 2012; Palmer, 1990; Papafragou, 2006). These studies may deviate on the precise definitions of subjectivity that are used, nevertheless there is a clear parallel in the way in which these theories characterize subjectivity, and the notion of subjectivity as speaker involvement adopted in cognitive linguistic theories. Discussing these studies in more detail is beyond the scope of the present study. It has been argued that subjective causal relations are more complex than objective causal relations (Noordman & De Blijzer, 2000; Sanders et al., 1992; Traxler, Sanford, Aked, & Moxey, 1997). Indeed, understanding subjective causal relations requires a meta-representation of others’ beliefs and conclusions (e.g. Oversteegen, 2005). Therefore, the processes underlying the comprehension of subjective causal relations have been related to Theory of Mind abilities (Sperber, 1997; Zufferey, 2010). Objective causal relations, on the other hand, do not require such meta-representation but simply relate two events in the physical world, and as such they may be easier to process. Data from acquisition studies and psycholinguistic experiments confirm that the difference between subjective and objective causality may have cognitive relevance. For instance, corpora of Dutch and English child language data show that subjective causal relations appear later than objective relations in both English and Dutch childlanguage (Evers-Vermeul & Sanders, 2011; Van Veen, 2011), suggesting that the former category can be considered as being 28|Chapter 2 more complex. This difference in complexity is paralleled by on-line processing data with adults. Studying on-line text processing in a self-paced reading experiment, Traxler, Sanford, Aked, and Moxey (1997) found that subjective causal relations (8b) induced longer reading times of the second clause, compared to objective causal relations (8a). (8) a. Rick almost died from shock because a poisonous snake bit him on the leg. b. Rick was walking in a remote area because a poisonous snake bit him on the leg. Note that in order to be able to measure the effects of subjective versus objective causal relations, the second clause of the relation has to contain exactly the same words in both conditions. As a result, the authors varied the content of the first clauses of the relations in order to be able to express either a subjective or an objective causal relation. An eye-tracking study by Traxler, Bybee, and Pickering (1997) demonstrated that the locus of the processing effect reported in Traxler, Sanford, Aked, and Moxey is around the main verb; it surfaced at the words bit him in example (8). Further experiments by Traxler, Sanford, Aked, and Moxey revealed that the delay in processing times for subjective causal relations is eliminated when the first clause of the relation contains explicit cues of subjectivity in the form of mental state predicates (John thinks), epistemic adverbs (maybe, perhaps) and modal verbs (may) (9). (9) [John thinks / Maybe] Rick was walking in a remote area because a poisonous snake bit him on the leg. According to Traxler, Sanford, Aked, and Moxey (1997), the longer processing times for English subjective compared to objective causal relations are caused by the fact that it has not been made clear that the first clause is a psychological event. They argue that the default interpretation of the first clause of a causal relation is an objective interpretation of the state of affairs in the world. Therefore, the processing effects associated with subjective causal relations surface because “the text does not signal that a less preferred [subjective] interpretation should be adopted” (p.89). Different results were obtained in a Dutch self–paced reading experiment by Noordman and De Blijzer (2000). The authors report longer reading times for the second clause of subjective (10b) compared to objective (10a) causal relations, even if the first clause of the subjective relation contains modal elements, which are markers of subjectivity (zal wel (must have) in (10b)). (10) a. Het meisje is nat geworden, omdat ze in de rivier is gesprongen. Causal connectives as processing instructions|29 The girl got wet, because she jumped in the river. b. Het meisje zal wel nat zijn geworden, want ze is in de rivier gesprongen. The girl must have got wet, because she jumped in the river. Noordman and De Blijzer propose that the comprehension of causal relations requires a match between the causal relation and a model of the world. Objective causal relations directly reflect real-world causality. Subjective relations, however, are more complex because they reflect realworld causality in a less direct fashion. Rather, these relations involve a line of reasoning on the basis of real-world causality. The reader has to check the possibility of that underlying causal relation in the world. Considering the experimental materials used in this study, one may question whether the longer reading times for subjective relations could also be attributed to the plausibility of those relations. For example, in relations such as (10b) the phrase zal wel (must have) is inserted in the first clause, which introduces uncertainty about the effect (Oversteegen, 2005). However, because it is inevitable that a person gets soaked from jumping into a river, the use of zal wel leads to a rather strange interpretation, as if it could also be possible to stay dry in such a situation. Thus, while Traxler, Sanford, Aked, and Moxey (1997) introduced epistemic markers that facilitate the interpretation of the subjective relation, the manipulation by Noordman and De Blijzer may have made these relations more difficult. The materials used by Traxler, Sanford, Aked, and Moxey (1997) may also raise questions about the plausibility of the relations. Indeed, one could argue that the subjective relations in this study are also less plausible than the objective relations. Note, however, that this cannot fully explain the results. Markers of subjectivity within S1 (such as possibly, John thinks) do not affect the plausibility of the subjective relation because the underlying reasoning is still the same, yet these markers do cancel out the disadvantage in processing time. In sum, experimental data from English and Dutch suggest that the distinction between subjective and objective causal relations affects online processing. Yet, it is unclear whether the distinction between subjective and objective causal connectives, which surfaces in many languages of the world, also affects online discourse processing. To our knowledge, there is only one previous study by Kamalski, Lentz, Sanders and Zwaan (2008) that specifically investigated the effects of various subjective and objective connectives and cue phrases on the processing of English subjective and objective causal relations. The authors report a tendency for a speeding-up effect at the entire clause following the objective markers compared to implicit objective relations. The subjective condition produced an interaction effect between segment and marker. Kamalski et al. concluded that subjective markers initially speed up the processing of subjective causal 30|Chapter 2 relations, but slow down the processing of the final words of the relation. One complication to this study, however, is that the categorization of subjective versus objective coherence markers in the materials is not based on actual language use. Therefore, it is unclear whether the two groups of subjective and objective markers manipulated by Kamalski et al. truly reflect these two categories. More importantly, the materials included connectives as linguistic markers that occur in both subjective and objective conditions. Ascribing the observed effects to the degree of subjectivity of the coherence markers is therefore difficult. 2.4 Subjective versus objective causal connectives: From usage patterns to online processing In recent years, a vast amount of (cross-) linguistic corpus research has been conducted to verify whether the distinction between subjective and objective causal relations is reflected in the lexicon of causal connectives (e.g. Stukker, Sanders, and Verhagen, 2009). An important question that arises from the literature is whether causal connectives themselves encode subjectivity, or whether this is purely a property of the relation between the combined segments. In English, for example, the connective because is used to express all sorts of backward causal relations and does not distinguish between subjective and objective relations (e.g. Couper- Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990). This means that the connective itself does not contribute to either a subjective or objective interpretation; this can only be derived by the linguistic characteristics of the text segments. In many languages of the world, however, the distinction between subjective and objective causal relations seems to be reflected in the distribution of forward and backward causal connectives and cue phrases (see Stukker & Sanders, 2012, for an overview). Table 1 provides a summary of the different connectives in the various languages. In French, for example, parce que is typically used to mark backward objective relations whereas car and puisque are considered to be its subjective counterparts (e.g. Anscombre & Ducrot, 1983; Le Groupe Lambda- λ, 1975; Zufferey, 2011). In forward causal relations, the markers donc and dès lors typically occur in subjective relations, while c’est pourquoi and de ce fait are prototypical markers of objective relations (Degand & Pander Maat, 2003). In Dutch backward causal relations the connective omdat is most frequently used in volitional objective causal relations and doordat is typically used in non-volitional causal relations. The connectives want and aangezien are considered to be prototypical markers of subjective relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009; submitted; Verhagen, 2005). With respect to forward connectives, the Dutch connective daardoor typically marks non-volitional objective causal relations, daarom is a prototypical Causal connectives as processing instructions|31 marker of volitional objective causal relations, and dus is typically used in subjective relations (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, 2005; Verhagen, 2005). Similarly, the German connectives weil and denn are associated with objective and subjective relations respectively (Pasch, 1983, in Stukker & Sanders, 2012). Interestingly, comparable distinctions show up in Latin (Bolkestein, 1991; Kroon, 1998), Portuguese (Lopes, 2009) and Mandarin Chinese (Li, EversVermeul, & Sanders, submitted; Xing, 2001 in Li et al., submitted). Table 1. Summary of subjective and objective causal connectives in French, German, and Dutch, analyzed in the literature. Direction French Subjective Objective Backward car; puisque parce que Forward donc; dès lors c’est pourquoi; de ce fait German Backward denn weil Dutch Backward want; aangezien omdat; doordat dus daarom; daardoor Foward These observations illustrate that in many languages of the world causal connectives specialize in specific subjective versus objective subtypes of causal relations. In this dissertation we will investigate whether such frequency data tell us something about the way in which causal connectives are processed. Frequency effects are a sensitive topic because these effects can be interpreted from two opposing perspectives. From one perspective, frequency effects are driven by the internalized structure of the language system. For example, the relation between frequency and comprehension complexity has been explained in terms of a preference to produce easier structures to more complex structures (e.g. Gibson, Schütze, & Salomon, 1996; Stevenson & Merlo, 1997). Others, however, argue that it works exactly the other way around in that frequency determines the way in which the language system is organized (Bybee, 2007). With respect to comprehension complexity, frequency is assumed to determine the ease of understanding (see Ellis, 2002, for an overview; Jurafsky, 1996; Seidenberg & MacDonald, 1999; Mitchell et al., 1995; Tabor, Juliano, & Tanenhaus, 1997). Here, we will not investigate the directionality of frequency effects, but focus on the question of whether there is a relation between connective usage patterns on the one hand, and online processing on the other. 32|Chapter 2 With respect to our ‘subjective’ and ‘objective’ causal connectives, there are two ways in which their usage patterns could be reflected in online processing and representation. These connectives may trigger the representation of both subjective and objective relations, of which the one that happens to be the most frequently used relation is dominant. This representation is therefore easiest to activate and harder to let go when the alternative applies. Alternatively, it could be the case that each causal connective triggers only one discourse representation, which is either subjective or objective, that corresponds to their prototypical usage. Slightly problematic for this latter account is the fact that causal connectives are sometimes also used to mark non-prototypical relations. Researchers have recognized that there is no black-and-white distinction between subjective and objective connectives on the basis of their usage patterns. See, for example, Table 2 in which the results from different corpus-based studies on want and omdat are summarized. The way in which the profiles of these connectives are established is by first stripping the causal relations of their connectives. Next the degree of subjectivity of the relation is determined by means of a paraphrase test. Subjective relations can be paraphrased by “the fact that P causes S’s claim / advice / conclusion that Q” (Sanders, 1997) or “this leads to the following conclusion” (Pander Maat & Degand, 2001). Objective causals are paraphrased by “The fact that P causes the fact that Q” (Sanders, 1997), “this has the following consequence”, or “this was the reason to perform the following act” (Pander Maat & Degand, 2001). Table 2 shows that, on average, want occurs most frequently in subjective relations whereas omdat is used most frequently in objective relations. However, this distinction is not that clear-cut in all studies. For example, on the basis of Degand and Pander Maat (2003) it seems that omdat does not really differentiate between objective and subjective relations (52% versus 48%), and the results from the chat conversations in Sanders and Spooren (submitted) indicate that want is often used to mark objective relations (40%). One explanation for this phenomenon is provided by Stukker and Sanders (2012) who interpret usage patterns in terms of the cognitive structures associated with human categorization. The authors conducted a meta-analysis concerning prototypicality characteristics in corpus data on French, German, and Dutch causal connectives. Results revealed that every instantiation of non-prototypical connective usage systematically contains characteristics that correspond to the connective’s more prototypical relational context. Thus, subjective relations with omdat are still considered more objective than subjective relations with want and vice versa. Causal connectives as processing instructions|33 Table 2. Distribution of want and omdat in subjective and objective causal relations, given in percentages of the analyzed occurrences. Want Omdat Subjective Objective Subjective Objective 68 32 8 82 Pit (2003) Newspaper texts 80 20 42 58 Degand & Pander Maat (2003) Newspaper texts 84 16 48 52 Sanders & Spooren (submitted) Spontaneous conversations (CGN) 59 40 10 89 Sanders & Spooren (submitted) Newspaper texts (D-COI, 2006) 61 39 5 95 Sanders & Spooren (submitted) 65 Chat conversations (VU Chat corpus) 35 5 95 Average 30 20 79 Pit (2003) Narrative text 70 Irrespective of their non-prototypical occurrences, there are clear differences between want and omdat. Want can be used in all relational contexts in which because occurs, that is, in subjective (11b) and objective (11a) causal relations. Omdat, on the other hand, cannot be used in subjective relations that involve abductive reasoning (11b). In these relations, a real-world effect (Karl left immediately) is taken as an argument to support the speaker’s conclusion about the cause (Karl was annoyed) (Pander Maat & Degand, 2001). This relation cannot possibly be expressed by the connective omdat, which leads to a reversed interpretation (This impossibility is expressed by the symbol # which indicates that the connective is not able to express the intended relation). The fact that Karl left immediately is interpreted as the cause of Karl’s annoyance, which does not make much sense2. (11) a. Karl was upset, because Ricky made him swim with sharks. Karl was boos, want Ricky heeft hem met haaien laten zwemmen. Karl was boos, omdat Ricky hem met haaien heeft laten zwemmen. b. Karl was annoyed, because he left immediately. Karl was geïrriteerd, want hij is meteen weer vertrokken. #Karl was geïrriteerd, omdat hij meteen weer is vertrokken. 2 Note that this could make sense if the pronoun he refers to some other discourse entity. 34|Chapter 2 There are two ways to interpret the fact that want can be used to express all kinds of causal relations. Similar to because, want could be underspecified and allow for both subjective and objective causal relations. Alternatively, want may encode that a relation is subjective and therefore forces a subjective interpretation in any causal relation. As such, want provides processing instructions that cue the interpretation of S1 as a conclusion or claim. One way to verify whether want is similar to because with respect to its processing instructions is by testing whether want has the same effect on the processing of subjective versus objective causal relations. However, in order to compare the processing effects of these two connectives we need to have data from comparable experiments in the two languages. We therefore created a Dutch version of the experiment by Traxler, Bybee, and Pickering (1997), as discussed in section 2.3, and used want in both subjective and objective causal relations. In order to be able to compare the two experiments we stayed close to the original materials, in which S1 varies in order to express either a subjective or an objective causal relation, and S2 is the same in both conditions. We are aware of the fact that these items could be improved with respect to the plausibility of the relations. However, as will become evident in Chapter 3, differences in plausibility cannot explain the results reported in the current study. Recall that Traxler, Bybee, and Pickering found that subjective causal relations (12b) led to longer processing times at the words bit him compared to objective causals (12a). (12) a. Rick almost died from shock because a poisonous snake bit him on the leg. b. Rick was walking in a remote area because a poisonous snake bit him on the leg. The time course of this effect is compatible with the idea that because is ambiguous between subjective and objective relations. After all, if this connective does not provide any cues about the type of causal relation it marks, it makes sense that effects of subjectivity arise at the moment in which the subjective relation can be established from the propositional content of the two clauses. If want is also underspecified with respect to the type of causal relation it marks, this connective should lead to the same processing pattern as observed in English with because. We therefore expect a processing delay for subjective compared to objective relations, which surfaces at the main verb. At this point in the sentence, the propositional content allows readers to construct either a subjective or an objective causal relation. Causal connectives as processing instructions|35 2.5. Experiment 2.5.1 Participants 21 Undergraduate students from Utrecht University participated in the experiment (19 female, mean age 22.0 age range 19–27 years). All participants were native speakers of Dutch and were paid for their participation. 2.5.2 Materials and design The materials consisted of 24 sets of sentences as in (13) which are Dutch versions of the English objective (a) and subjective (b) items as used by Traxler, Bybee, and Pickering (1997) (see Appendix 1 for more examples). Both relations are marked by the connective want. (13) a. Hanneke was buiten adem, want ze was vier trappen afgerend om de post te halen. [Hanneke was out of breath, want she was four stairs ran down to the mail get.] Hanneke was out of breath, because she ran down four stairs to get the mail. b. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. [Hanneke was in a hurry, want she was four stairs ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. The 24 sets were divided over two lists, according to a Latin square design, so that each list contained only one version of a set. In addition, 72 unrelated filler items were inserted in each list. Line breaks were placed right after the first clause and before the connective. We made sure that the regions of interest, in the clause following the connective, were not situated at the end of the first line or at the beginning of the second line. This is important because the so-called return sweep, jumping to the next line, causes noise in the eye movements (see Cozijn, 2000, for more details). Verification statements were randomly divided over the stimuli and appeared after 25% of the items. Participants were informed to respond to these statements by pressing the ‘yes’ or ‘no’ button on the button box. 2.5.3 Apparatus and Procedure An SMI Eyelink I head-mounted eye-tracker was used, controled by FEP software (Veenker, 2006), with which both eyes were sampled at 250 Hz. The Eyelink I eye-tracker has a tracking range of 30 degrees horizontally and 20 degrees vertically, with a gaze position accuracy of 0.5 to 1.0 degrees. Gaze positions are corrected for head movements by an optical head-tracking camera on the headset, and four reflectors on the subject monitor. All participants were individually tested in a testing booth at the University. Before the experiment started, participants were informed about the 36|Chapter 2 procedure. First the experimenter adjusted the headband and made sure the participant was comfortably seated. Participants were asked not to move their heads or blink excessively during the experiment. Each experiment started with a calibration procedure during which subjects had to follow a small circle on the screen moving through nine positions, followed by a similar validation procedure. This procedure was repeated before each block. The experiment started with a practice trial of 5 items. Drift corrections were performed before each sentence. 2.5.4 Data clean-up We used the fixation analysis program Fixation (Cozijn, 1994) to check the assignment of fixations to the words in the texts. This is necessary because fixations can sometimes land at the borders of the text. These fixations were manually assigned to the words in question. Also, head movements and poor calibrations can lead to shifted fixation patterns. These cases were corrected by moving the entire pattern in a vertical direction (but never horizontally). In most cases, the assignment of fixations to the text was unproblematic. Ambiguous cases were discarded from the analyses 2.5.5 Eye-tracking measures Several eye-tracking measures have been developed to capture the dynamics of reading processes. Because these measures are highly correlated it is impossible to pinpoint the cognitive processes that these individual measures reflect. However, a general division can be made between so-called “early” measures, and “late” measures. Early measures, such as first fixation duration and first pass reading times, measure the first view of a word or region and are often associated with cognitive processes related to word recognition and lexical access. Late measures, such as regression path duration and total time, take rereading and regressions into account and are often associated with processes of integration and reanalysis. In order to obtain a meaningful reading pattern, it is essential to examine different measures rather than a single measure of processing time (Rayner, 1998). In the present study we analyzed the following measures: first fixation duration, first pass reading times, regression path duration and total reading time. First fixation duration is the duration of the first fixation on a word or region, and reflects the immediate processing difficulties a reader has when viewing that region for the first time. This measure is especially suitable when the region of interest is short, or when the researcher wants to capture spillover effects from the previous region (Clifton, Straub, & Rayner, 2007). First pass reading times (Inhoff & Radach, 1998; Rayner, 1998) is what Rayner and Duffy (1986) call gaze duration for single words and consists of all fixations within a region (including saccades) before moving into a Causal connectives as processing instructions|37 forward or a backward direction. Regression path duration (Konieczny, Hemforth, Scheepers, & Strube, 1997) consists of all fixations on a region before passing on in a forward direction, including rereading of previous material. This measure is also referred to as total-pass reading time (Kennedy, Murray, Jennings, & Reid, 1989), go-past reading time (Clifton, Bock & Rado, 2000) and cumulative region reading time (Mitchell, Brysbaert, Grondelaers, & Swanepoel, 2000). Total reading time is the Total time spent at a region. This measure captures the time required for reanalysis when a piece of information is not completely processed during the first reading (Rayner & Sereno, 1994). 2.5.6 Results Example (14) illustrates how the items were divided into regions. Region 1 is the connective, Region 3 consists of the main verb and Region 2 comprises all the information in between Region 1 and 3 (in most cases a noun phrase and an auxiliary). Region 4 consists of the final words of the relation. (14) |Want 1| ze was vier trappen 2 | afgerend 3| om de post te halen 4| |Because 1 | she was four stairs 2 | ran down 3 | to the mail get 4 | Correct answers to the verification statements were given in 84% of the trials. Blinks were extracted from the data. All observations that were two standard deviations above or below item and subject mean for each position and condition were excluded from the analysis. Following these criteria we removed 1.2% of the data (171 cases). Means are reported in Table 2. We performed Linear Mixed Effects Regression analyses (LMER) (Baayen, 2008) on the data, with subjects and items as crossed random effects and Relation (subjective versus objective), as fixed effect. Eyemovement data typically have a lot of missing values, especially if the regions of interest are short. However, multilevel analyses such as LMER are robust against missing data (Quené & van den Bergh, 2004). An additional advantage of this technique over traditional ANOVA is the fact that it deals with item and subject variability in a single model (See Quené & van den Bergh, 2004, for more details). Log-transformations were performed on the data in order to meet the normality requirements of linear modeling. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). Traxler, Bybee, and Pickering (1997) reported longer reading times in subjective compared to objective causal relations at the text region containing the main verb (Region 3). In our study, however, no significant effect of Relation surfaced at this region in any of the measures (first fixation duration: ß=0.00, SE=0.03, p(MCMC)>0.05; first pass reading times: ß=0.05, SE=0.04, p(MCMC)>0.05; regression path duration: ß=0.04, SE=0.05, 38|Chapter 2 p(MCMC)>0.05; total reading time: ß=-0.02, SE=0.05, p(MCMC)>0.05). No effects were observed in any of the other regions. Table 2.

These markers provide explicit information about the causal relation between two text-segments, which otherwise has to be inferred on the basis of the discourse context. Indeed, experimental evidence shows that the presence of a causal connective leads to a faster processing of at least the first part of the immediately following clause (Haberlandt, 1982; Millis, Golding, & Barker, 1995; Millis & Just, 1994; Noordman & Vonk, 1997), more accurate responses to comprehension questions (Millis & Just, 1994) and superior recall performance (Caron, Micko, & Thuring, 1988; Millis, Golding, & Barker, 1995). These studies, however, are limited to objective causal relations. To the best of our knowledge, no other studies have investigated whether causal connectives also provide information about the exact type of causal relation they mark: whether they mark a subjective or an objective causal relation. This idea stems from the observation that in many languages of the world, the distinction between subjective and objective causal relations seems to be reflected in the lexicon of causal connectives. In addition, it has been observed that subjective causal relations are acquired later (Evers-Vermeul & Sanders, 2011; Van Veen, 2011) and processed slower (Noordman & De Blijzer, 2000; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997) compared to objective causal Causal connectives as processing instructions|39 relations. This suggests that the distinction between these two types of causal relations is cognitively real. As such, it is to be expected that the difference between objective and subjective connectives is reflected in online processing. In this chapter, we focused on the Dutch backward causal connectives want and omdat. These connectives are both translated by because, however, where because can be used to mark both subjective and objective causal relations (e.g. Couper- Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990), the Dutch connectives want and omdat specialize in one or the other. Various corpus-based studies on the semanticpragmatic profiles of Dutch causal connectives have revealed that want is most frequently used in subjective relations, but omdat occurs most frequently in objective relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009, 2012; Verhagen, 2005). This chapter provides a first attempt to investigate this issue from a processing perspective. On the basis of the frequency data provided by corpus research, it could be argued that want and omdat will results in different processing and representation patterns. However, the differences between the semantic profiles of want and omdat are not clear-cut: both connectives are also used in non-prototypical relations. This observation could be potentially problematic for the claim that these two connectives are markers of different cognitive categories. At the same time, there are clear differences between the two connectives: similar to because, want can be used in all types of causal relations. Omdat, however, cannot be used in a subtype of subjective relations (15). (15) Karl was annoyed, because he left immediately. Karl was geïrriteerd, want hij is meteen weer vertrokken. #Karl was geïrriteerd, omdat hij meteen weer is vertrokken. This observation could in principle mean that want is underspecified with respect to the type of causal relation it marks, and is therefore similar to because. We hypothesized that if want and because are similar with respect to their processing instructions, they should also have the same effect on the processing of subjective versus objective causal relations. This hypothesis was tested in a Dutch version of the eye-tracking experiment reported in Traxler, Bybee, and Pickering (1997). Traxler, Bybee, and Pickering found longer processing times for subjective causal relations (16b) compared to objective causals (16a) at the words bit him. (16) a. Rick almost died from shock because a poisonous snake bit him on the leg. b. Rick was walking in a remote area because a poisonous snake bit him on the leg. 40|Chapter 2 The position of this effect is fully compatible with the assumption that because does not provide information about the degree of subjectivity of the causal relation it marks. Language users can therefore only derive this information from the propositional content, which explains why the effects of subjectivity arise relatively late in the second sentence. If want is similar to because, want should lead to a similar processing pattern in Dutch subjective versus objective causal relations. This effect was expected to arise at the moment in which the relation could be established from the content, which is Region 3 in our experiment. Our results, however, did not reveal any processing differences between subjective and objective relations at all. Does this mean that our experiment is flawed, or is it possible that the properties of the connective want were responsible for this null effect? In what follows we will discuss three possible explanations for this outcome. One possibility is that want makes objective relations more difficult because the degree of subjectivity of the connective does not match the degree of subjectivity of the relation. According to Pander Maat and Degand (2001) causal connectives encode a degree of subjectivity that contributes to the degree of subjectivity of the relation. However, they argue that these two must concord: a connective is inappropriate if its degree of subjectivity is too high or too low for the level of subjectivity expressed by the relation (p.230). Therefore, want may have increased the overall complexity of the objective relations in our experiment. Given that the match between the relation and the connective can only be evaluated when the reader is able to construct the causal relations, the position of this effect coincides with the position where we expected to find the processing effects of subjective causal relations. This may explain why we did not observe longer processing times in subjective compared to objective causal relations. A second explanation may be that we did not replicate the processing asymmetry between subjective and objective causal relations because want facilitates the subjective interpretation. Traxler, Sanford, Aked, and Moxey (1997) (Experiment 2) found no processing difference between subjective and objective causal relations when the first clauses of both relations contain explicit cues of subjectivity in the form of epistemic modal adverbs (maybe, possibly) (17). They explained this finding by stating that mental space builders that introduce possibility facilitate the construction of the subjective interpretation (p.93). Possibly, want also functions as such a space builder that facilitates the construction of a subjective relation. (17) [Maybe] Rick was walking in a remote area because a poisonous snake bit him on the leg. Causal connectives as processing instructions|41 As a third option we would like to propose that want may encode semantic-pragmatic information, corresponding to its usage pattern, which triggers a subjective interpretation of any causal relation. This would mean that the construction of the subjective relation arises before the propositional content of S2 is processed, and occurs irrespective of the underlying relation between S1 and S2 without a connective. Example (18a), for example, contains an objective causal relation that is left implicit. In this example, the second clause provides the cause of the situation in S1: the fact that Ricky wants Karl to go bungee jumping leads to the situation that Karl is afraid. (18) a. Karl is bang. Hij moet gaan bungeejumpen van Ricky. Karl is afraid. Ricky wants him to go bungee jumping. b. Karl is bang want hij moet gaan bungeejumpen van Ricky. Karl is afraid because Ricky wants him to go bungee jumping. The use of want in this relation (18b), however, could have the effect of turning the preceding clause into the speaker’s conclusion about a situation. As such, want could function as a trigger for the construction of a subjective causal relation, leading to an interpretation of S1 as “Karl is probably afraid”. Therefore, the objective relations in our experiment may have been processed as subjective relations. If the construction of a subjective relation is indeed cognitively demanding, it may be the case that want leads to a processing slowdown as soon as the connective is processed. But because this connective was used in both types of relations, we did not observe any effects in our experiment. On the basis of the experiment presented in this chapter it is impossible to distinguish between these three explanations. Our findings, however, do suggest that the Dutch connective want and the English connective because do not encode the same information about the discourse structure. In Chapter 3 we will further investigate this issue by using the Dutch connectives in their prototypical relation: want in subjective causal relations and omdat in objective causal relations. If our first explanation holds, and want makes objective relations more difficult, using the connectives in their prototypical relation should lead to a replication of the results reported in Traxler, Bybee, and Pickering (1997). If, following our second explanation, want facilitates the processing of subjective causal relations, we may expect to find no processing difference between subjective and objective causal relations marked by want and omdat respectively. If, however, our third suggestion holds and want triggers the representation of a subjective relation, we may expect an earlier effect of subjectivity compared to Traxler, Bybee, and Pickering. Chapter 3 Causal connectives in discourse processing: How differences in subjectivity are reflected in eyemovements1 3.1 Introduction Understanding discourse is not simply a matter of understanding the content of the clauses involved. In order to achieve successful comprehension, language users also need to be able to understand the relations between these clauses. Such coherence relations (Hobbs, 1979; Mann & Thompson, 1988; Sanders, Spooren, & Noordman, 1992) can be of an additive, causal, temporal, or adversative nature. The present study focuses on causal coherence relations, which can be made explicit by coherence markers such as connectives, cue phrases (that’s why) and signaling phrases (The problem is… A solution might be…). It is generally assumed that causal connectives provide crucial information about the discourse representation; they signal that a causal relation is to be established between two text segments. These markers are therefore assumed to provide processing instructions, which specify the enfolding discourse structure (e.g. Britton, 1994; Gernsbacher, 1997; Sanders & Spooren, 2007). Indeed, much experimental work has been conducted in order to investigate the online processing effects associated with causal connectives. A central point of interest has been the time course of such effects. As discussed in Chapter 2, a general finding in many studies is that the presence of a causal connective leads to an immediate processing facilitation compared to implicit relations (Cozijn, 2000; Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Maury & Teisserenc, 2005; Millis & Just, 1994). In addition, some studies have also reported longer processing times at the final words of causal relations if they are marked by causal connectives (Cozijn, 2000; Cozijn et al., 2011; Millis & Just, 1994). As discussed in Chapter 2, these effects have been explained in diverging ways, depending on the function ascribed to connectives. According to Millis and Just’s Delayed Integration Hypothesis, causal connectives instruct the reader to delay the integration of two clauses until the second clause is processed. Cozijn et al. (2011), on the other hand, argue that connectives facilitate the immediate integration of two clauses, hence explaining the immediate speeding up effect. Even though the differences with respect to the time course of these 1 An almost identical version of this chapter will appear as Canestrelli, A. R., Mak, W. M., & Sanders, T.J.M. (To appear).

DOI:10.1080/01690965.2012.685885. 44|Chapter 3 effects is not the focus of the present study, the results presented in this chapter contribute to this discussion by shedding more light on the function of causal connectives during processing. On the basis of the empirical data so far it can be concluded that information about the discourse structure encoded in causal connectives plays a significant role during online processing. Crucially, this information consists of different components. First, causal connectives inform readers that a causal relation needs to be established between two text segments. In addition, they specify the temporal order of events. Forward connectives, such as therefore, indicate a linear order between events in which causes precede effects. In case of backward causal connectives, such as because, the linear order of events is interrupted and effects precede causes in the text. In the present chapter we investigate whether a third source of information, namely subjectivity, could also play a role in the processing of causal connectives. 3.2 Causal connectives and subjective versus objective causal relations Languages differ with respect to the amount of information encoded in causal connectives. In English, for example, the connective because is used to express all sorts of backward causal relations and does not distinguish between relations that express real-world causation (1b) versus those that involve subjective reasoning (1a) (e.g. Couper- Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990). Note that we use the term of backward causation to describe the order of events as they are presented in the text, that is: effect precedes cause, or conclusion/ claim precedes argument. (1) a. Peter must be sick because he looks pale. b. The cup broke because it fell off the table The distinction between these types of causal relations is also referred to as ‘objective’ versus ‘subjective’ (e.g., Degand & Pander Maat, 2003; Pander Maat & Degand, 2001; Pander Maat & Sanders, 2001), ‘semantic’ versus ‘pragmatic’ (Van Dijk, 1979; Sanders et al., 1992), ‘internal’ versus ‘external’ (Halliday & Hasan, 1976), or ‘content’ versus ‘epistemic’ relations (Sweetser, 1990). In this study we will refer to these relations as objective and subjective causal relations. One crucial difference between these two subtypes of causal relations is that subjective relations involve mental states (Knott, 2001) whereas the states of affairs in objective relations are presented as facts in the world. In subjective relations such as (1a), the first clause is a claim, conclusion, or belief on behalf of the speaker, based on the real-world state in the second Differences in subjectivity reflected in eye-movements|45 clause (Peter looking pale). Therefore, the speaker is responsible for constructing the causal relation, and reference to the speaker is required in order to understand this type of relations. In objective causal relations, such as (1b), the speaker is not involved in the construction of the causal relation, but is merely reporting the situation in S1 and S2 as being causally related in the real world (Pander Maat & Sanders, 2000). A general assumption in the literature on subjective causality, and epistemic modality in general, is that it requires a meta-representation of others’ beliefs and conclusions (e.g. Oversteegen, 2005). Therefore, the processes underlying the comprehension of subjective causal relations have been related to Theory of Mind abilities (Sperber, 1997; Zufferey, 2010). In addition, epistemic modality is assumed to involve an assessment of “the probability of a state of affairs from the speaker’s point of view” (Jaszczolt, 2003). Such considerations have led to the idea that subjective causal relations are more complex than objective causal relations (Noordman & De Blijzer, 2000; Sanders et al., 1992; Traxler, Sanford, Aked, & Moxey, 1997). The difference in cognitive complexity between these types of relations becomes apparent in language acquisition and online processing in adults. Corpora of Dutch and English child language data show that subjective causal relations appear later than objective relations in English, French, and Dutch children (Evers-Vermeul & Sanders, 2011; Spooren & Sanders, 2008; Van Veen, 2011; Zufferey, 2010) suggesting that the former category is more complex. Studying online text processing in English, Traxler, Bybee, and Pickering (1997) found that subjective causal relations (such as2b) produced longer reading times compared to objective causal relations (2a) 2 . This difference surfaced at the moment that readers were able to construct the causal relation from the content, at the words didn’t score in the example. (2) a. The goalkeeper won the game because the other team didn’t score any goals. b. The goalkeeper knew how to play the game because the other team didn’t score any goals. As pointed out at the beginning of this section, the connective because is underspecified with respect to the type of causal relation it signals. Therefore, the processing instructions provided by this connective may be no more specific than relating S2 to S1 in some sort of causal relation. In order to arrive at a subjective interpretation of a relation marked by this general connective, readers have to rely entirely on the content, world knowledge and other linguistic cues of subjectivity. 2 Traxler, Bybee, and Pickering (1997) use the terms diagnostic and causal relations. 46|Chapter 3 In many languages of the world, however, the distinction between subjective and objective causal relations seems to be reflected in the distribution of causal connectives (See Stukker & Sanders, 2012, for an overview). In French, the connective parce que is typically used to mark objective relations while car and puisque are considered to be markers of subjective relations (e.g. Anscombre & Ducrot, 1983; Le Groupe Lambda- λ, 1975; Zufferey, 2011). In Dutch, the connective omdat is most frequently used in objective relations whereas want is considered to be a prototypical marker of subjective relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009; Verhagen, 2005). Similarly, the German connectives weil and denn are typically associated with objective and subjective relations respectively (Pasch, 1983). Interestingly, similar distinctions show up in Latin (Bolkestein, 1991; Kroon, 1998), Portuguese (Lopes, 2009) and Mandarin Chinese (Xing, 2001). These observations illustrate that, in many languages, causal connectives specialize in specific subtypes of causal relations. It is feasible that knowledge of such usage patterns is helpful during reading (Murray, 1997). In fact, in usage based approaches usage patterns are related to the cognitive representation that language users form of a given construction. The more frequent a token or grammatical construction is, the stronger its cognitive representation, a process also referred to as entrenchment (Bybee, 2007). Although several studies have investigated the processing effects associated with causal (and non-causal) connectives, so far it is unknown whether the distinction between subjective and more objective causal connectives also plays a role in the processing and representation of causal relations. In the present study we investigate whether language users make use of this type of information during online discourse processing and, if so, when this information becomes available. We focus on the Dutch causal connectives want and omdat, although the distinction is expected to be relevant in all languages that display a similar distribution. 3.3 Want versus omdat Want and omdat are connectives that mark backward causal relations and can both be translated by because (see example 3). Both connectives are highly frequent in Dutch; their log frequency based on the Celex corpus of written Dutch (Baayen, Piepenbrock, & Gulikers, 1995) is 4.5 and 4.6 (per million words) respectively. Yet, these connectives differ with respect to their syntactic properties. Want is a coordinating connective, whereas omdat introduces a subordinate clause. In Dutch, this syntactic difference is reflected in the word order in the embedded clause: in Dutch coordinate clauses the finite verb is in second position (3a) while subordinate clauses are verb final (3b). Differences in subjectivity reflected in eye-movements|47 (3) a. Peter zal wel ziek zijn want hij ziet bleek. [Peter must ill be because he looks pale.] Peter must be ill because he looks pale. b. Peter blijft thuis omdat hij ziek is. [Peter stays home because he ill is.] Peter stays at home because he is ill. We will not go into this syntactic difference but focus on the semanticpragmatic differences between want and omdat. Although there is no blackand-white distinction between these two connectives, want occurs most frequently in subjective CLAIM-ARGUMENT relations, whereas omdat is most frequently used in objective CONSEQUENCE-CAUSE relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009). As discussed in Chapter 2, the general conclusion based on corpus studies on these two connectives is that they have clear preferences for a specific type of relation. Indeed, omdat and want cannot simply be interchanged without altering the causal relation expressed. For example, (4a) is a diagnostic subjective relation in which the first clause consists of a claim regarding the cause of the situation in the second clause. In other words, the low temperature in the house is taken as evidence for the claim that the heating must be broken. However, the relation gets a different interpretation if the connective omdat is used. The use of omdat in (4b) changes the relation from CLAIM-ARGUMENT into CONSEQUENCE-CAUSE. As a result, the cold temperature is interpreted as the real-world cause of the broken heating, which could make sense in case of frozen pipes. (4) a. De verwarming is kapot want het is koud in huis. The heating is broken because the house is cold. b. De verwarming is kapot omdat het koud is in huis. The heating is broken because the house is cold. At the same time, it is less clear whether objective relations change by altering the connective. In (5a), the fact that Marc is ill leads to the situation that he stays at home. Here, omdat can be replaced by the connective want without changing the relation entirely. However, as we have discussed in Chapter 2, want does allow for an additional interpretation in which the fact that Marc is ill leads to the conclusion that he stays at home. (5) a. Marc blijft thuis omdat hij ziek is. Marc stays at home because he is ill. b. Marc blijft thuis want hij is ziek. Marc stays at home because he is ill. 48|Chapter 3 Since causal connectives provide crucial information about the discourse structure, we propose that their processing instructions go beyond simply marking that a causal relation exists between two text segments. Given the fact that want and omdat are prototypical markers of subjective and objective relations respectively, we hypothesize that this subtle information is encoded in their processing instructions and guides language users when processing a causal relation. This implies that want actually induces a subjective representation where omdat triggers an objective interpretation. In order to test the effect of the Dutch connectives on discourse processing, we started out with an eye-tracking experiment involving a Dutch translation of the materials used by Traxler, Bybee, and Pickering (1997), as used in Chapter 2. An additional difference between want and omdat is that omdat is a subordinating connective whereas want introduces a coordinated clause. In Experiment 2 we investigate whether this syntactic difference independently affects online discourse processing. The main research question in this study is whether the information about the discourse structure that want and omdat provide is used by the reader to establish the relation between two pieces of text. We know from the English results by Traxler, Bybee, and Pickering that there is a delay in reading times in subjective relations as soon as the relation can be established from the content of the second clause. If the discourse information provided by want and omdat is not used immediately by the reader, we expect the same result in Dutch as in English: a delay in reading times in subjective relations in the text region where the relation between S1 and S2 can be established from the content. In our materials that would be at the main verb. If, however, the discourse information encoded in the connectives is put to use immediately, the effect may occur earlier, at or directly after the connective. 3.4 Experiment 1 3.4.1 Participants Twenty-one undergraduate students from Utrecht University participated in the experiment (20 female, mean age 23.7 age range 18–45 years). All participants were native speakers of Dutch and were paid for their participation. 3.4.2 Materials and design The materials consisted of 24 sets of sentences as used in Chapter 2, which are Dutch versions of the English objective (6a) and subjective (6b) items as used by Traxler, Bybee, and Pickering (see Appendix 2 for more examples). The objective condition is marked by omdat and the subjective condition is Differences in subjectivity reflected in eye-movements|49 marked by want. Although the position of the verb varied across conditions, all text regions that were used in the analysis contained the same words. (6) a. Hanneke was buiten adem, omdat ze vier trappen was afgerend om de post te halen. [Hanneke was out of breath, omdat she four stairs was ran down to the mail get.] Hanneke was out of breath, because she ran down four stairs to get the mail. b. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. [Hanneke was in a hurry, want she was four stairs ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. The 24 sets were divided over two lists, according to a Latin square design, so that each list contained only one version of a set. In addition, 72 filler items were inserted in each list. Line breaks were placed right after the first clause and before the connective. We made sure that the regions of interest, in the clause following the connective, were not situated at the end of the first line or at the beginning of the second line. This is important because the so-called return sweep, jumping to the next line, causes noise in the eye movement data (Rayner, 1998). Verification statements were randomly divided over the stimuli and appeared after 25% of the items. Participants were informed to respond to these statements by pressing the ‘yes’ or ‘no’ button on the button box. 3.4.3 Apparatus and Procedure A Sensomotoric Instruments (SMI) Eyelink I head-mounted eye-tracker was used, controled by FEP software (Veenker, 2006), with which both eyes were sampled at 250 Hz. The Eyelink I eye-tracker has a tracking range of 30 degrees horizontally and 20 degrees vertically, with a gaze position accuracy of 0.5 to 1.0 degrees. Gaze positions are corrected for head movements by an optical head-tracking camera on the headset, and four reflectors on the subject monitor. All participants were individually tested in a testing booth at the University. Before the experiment started, participants were informed about the procedure and were asked to read the instructions carefully. First the experimenter adjusted the headband and made sure the participant was comfortably seated. Participants were asked not to move their heads or blink excessively during the experiment. Each experiment started with a calibration procedure during which subjects had to follow a small circle on the screen moving through nine positions, followed by a similar validation procedure. This procedure was repeated before each block. The experiment started with a practice trial of five items. Drift corrections were performed before each sentence. 50|Chapter 3 3.4.4 Results Example (7) illustrates how the items were divided into regions. Region 1 is the connective, Region 3 consists of the main verb and Region 2 contains all the information in between Region 1 and 3 (in most cases a noun phrase plus an auxiliary). Region 4 consists of the final words of the sentence. (7) | Want / omdat 1 | ze was vier trappen 2 | afgerend 3 | om de post te halen 4 | | Because 1 | she was four stairs 2 | ran down 3 | to the mail get 4 | Correct answers to the verification statements were given in 85% of the trials. Blinks and missing observations, due to skipped regions, were extracted from the data. All observations that were two standard deviations above or below item and subject mean for each position and condition (75 cases) were excluded from the analysis. Following these criteria we removed 1% of the data. We computed the following measures: first fixation duration, first pass reading times, regression path duration and total reading time. First fixation duration is the duration of the first fixation on a region. First pass reading times is what Rayner and Duffy (1986) call gaze duration for single words and consists of all fixations within a region (including saccades) before moving into a forward or a backward direction. Regression path duration (Konieczny, Hemforth, Scheepers, & Strube, 1997) consists of all fixations on a region before passing on in a forward direction, including rereading of previous material. Total reading time is the Total time spent at a region. Means are reported in Table 1. Table 1.

This technique has several advantages over traditional ANOVA, such as its ability to handle missing data and the fact that it deals with item and subject variability in a single model (See Quené & van den Bergh, 2004, for more details). Before the analysis, log-transformations were performed on the data in order to meet the normality requirements of linear modeling3. Markov Chain Monte Carlo (MCMC) sampling was used to estimate the p values (Baayen, 2008). At Region 2, the words directly following the connective, we observed longer first pass reading times in subjective causal relations compared to objective relations (ß=0.231, SE=0.058, t=3.95, p(MCMC)<.01). The same pattern of result surfaced in regression path duration (ß=0.108, SE=0.042, t=2.56, p(MCMC)<.05) and total time (ß=0.155, SE=0.043, t=3.61 p(MCMC)<.01). None of the other regions produced significant effects. 3.4.5 Discussion The results indicate that, as in English, Dutch objective causal relations with omdat are associated with shorter processing times compared to subjective causal relations with want. However, in Dutch this effect arises earlier compared to English. Namely, on the first segment following the connective, before the main verb is processed. Recall that Traxler, Bybee, and Pickering (1997) observed a processing difference between English subjective and objective relations with because in the prefinal region, didn’t score in example (2a) here repeated in (8). (8) The goalkeeper knew how to play the game because the other team didn’t score any goals. Note that in English this is the first position in the sentence at which all the necessary information is available to readers to establish the causal relation. The effects in our experiment with Dutch causal relations arise at the region immediately following the connective. At this point in the sentence it is not at all clear what the precise causal relation will be. This implies that the cognitive processes responsible for the longer processing times for subjective relations in our experiment are activated by the connective, rather than related to the actual content of the relation. These results suggest that the subtle semantic-pragmatic information about the subtype of causal relation that causal connectives mark immediately affects 3 The untransformed data produced similar results in all experiments. 52|Chapter 3 online processing. This would mean that omdat provides processing instructions that trigger the representation of an objective causal relation between S1 and S2. Want, on the other hand, should immediately trigger the construction of a subjective causal relation. However, these hypotheses crucially rely on the assumption that the immediate processing difference between want and omdat is the result of the same cognitive operations as reflected in the processing difference between subjective and objective relations in English. A way to verify this assumption is by further investigating the source of both effects. A series of self-paced reading experiments have demonstrated that the delay in processing times for English subjective compared to objective causals can be overcome by introducing epistemic markers, such as John thinks and perhaps (9) (Traxler, Sanford, Aked, & Moxey, 1997). These markers make clear that the first clause is to be taken as a belief or possibility, and thus explicitly mark the information as being subjective. (9) John thinks the goalkeeper knew how to play the game because the other team didn’t score any goals. These findings illustrate that if the reader is already aware that a relation is subjective, the content of that relation no longer induces any processing difficulties. This suggests that it may be the construction of the subjective representation that is responsible for the longer processing time in subjective compared to objective causal relations. Recall that subjective causal relations are assumed to involve a meta-representation of others’ beliefs or conclusions (e.g. Knott, 2001; Oversteegen, 2005; Zufferey, 2010). In English subjective causal relations with because that lack other markers of subjectivity, this meta-representation is triggered at the moment the relation can be established from the content. We propose that, being a prototypical marker of subjective relations, the connective want by itself triggers this meta-representation and that it is in fact the construction of this representation that increases the cognitive load. If the immediate processing difference between want and omdat indeed reflects the same processes as the observed processing difference between English subjective and objective causals, this effect should also be canceled out by epistemic markers preceding the connective want. We therefore conducted a second experiment in which we added a subjective condition with want containing epistemic markers in the first clause. An additional advantage of this experimental setup is that it allows us to assess whether the syntactic difference between want and omdat independently affects online processing. Recall that want is a coordinating connective, whereas omdat introduces a subordinate clause. In Dutch, this syntactic difference is reflected in the word order in the embedded clause: in Dutch coordinate Differences in subjectivity reflected in eye-movements|53 clauses the verb precedes the object. In a subordinate clause this order is inversed. Adding epistemic markers to S1 affects the interpretation of that clause, yet it does not influence the syntactic structure of the embedded clause. Therefore, the sentences in these two conditions have the same word order. 3.4 Experiment 2 3.5.1 Participants Forty undergraduate students from Utrecht University, none of which participated in Experiment 1, took part in the experiment (31 female, mean age 21.6 age range 16–50 years). All participants were native speakers of Dutch and were paid for their participation. 3.5.2 Materials and design The materials, design and procedure were the same as in Experiment 1. The only difference between the two studies is that we added a subjective condition marked by volgens (according to) followed by a proper name in the first clause (10c) (see Appendix 2 for more examples). This adverbial construction explicitly signals that the information in S1 is someone’s conclusion or belief. The proper name always mismatched the protagonist in the relation with respect to its gender, in order to avoid pronoun ambiguities. (10) a.

All observations that were two standard deviations above or below item and subject mean for each position and condition (110 cases) were excluded from the analysis. Following these criteria we removed 0.8% of the data. Correct answers to the verification statements were given in 91% of the trials. Regions were defined as in 54|Chapter 3 Experiment 1, see example (7). Again, we analyzed the log-transformations of the following measures: first fixation duration, first pass reading times, regression path duration and total time. Means are reported in table 2.

There was no processing difference between objective and marked subjective relations (ß=-0.014, SE=0.029, t=0.49, p(MCMC)>.05).

Subjective relations without epistemic markers produced longer fixation times compared to objective relations (ß=0.169, SE=0.097, t=1.7, p(MCMC)<.05, one tailed) however, the difference with subjective relations that contained epistemic markers did not reach significance (ß=0.139, SE=0.097, t=1.43, p(MCMC)>.05). There was no difference between objective relations and marked subjective relations (ß=0.030, SE=0.097, t=0.31, p(MCMC)>.05). Total time produced significant differences at Region 1, which is the connective. This measure was shorter in the subjective condition (want) containing epistemic markers compared to the unmarked subjective (want) Differences in subjectivity reflected in eye-movements|55 (ß=-0.179, SE=0.053, t=3.38, p(MCMC)<.01) and objective (omdat) condition (ß=-0.120, SE=0.050, t=2.44 p(MCMC)<.05). There was no significant difference between objective and unmarked subjective relations (ß=0.059, SE=0.051, t=1.14, p(MCMC)>.05). No other significant effects surfaced from the analyses. 3.5.4 Discussion In Experiment 2 we observed the same effect as in Experiment 1. Want in subjective relations without epistemic markers leads to longer processing times compared to omdat relations. This effect surfaced at the same position in the sentence as observed in Experiment 1, at the words immediately following the connectives. Conversely, if want is preceded by epistemic markers in S1, we observe no processing differences between omdat and want relations in any of the measures. These findings demonstrate that the processing difference between want and omdat reflects the same processes as the observed difference between subjective and objective causals in English. Both effects are canceled out by the presence of epistemic markers in the first clause of the relation. These markers inform the reader that the information in the first clause is someone’s belief, claim or conclusion, rather than an objective description of the state of affairs in the real world. It is this status that we believe lies at the heart of the processing effects associated with want and subjective relations in general. We propose that subjective connectives such as want, in addition to being a causal marker, trigger the representation of S1 as a mental state, and that it is the construction of this representation that increases the cognitive load. Indeed, the fact that the presence of epistemic markers such as ‘according to X’ cancels out the effect at the connective want indicates that these elements have a shared function. If the first clause of a subjective causal relation already triggers a subjective representation, no differences between want and omdat arise because the relevant operation has already been executed before the connectives are processed. The effects in total time reveal that the presence of epistemic markers also facilitates the processing of the connective want during its second reading. This measure captures the time required for reanalysis when a piece of information is not completely processed during the first reading (Rayner & Sereno, 1994). When readers arrive at the end of the causal relation, they need to spend more time at the connective want in the unmarked compared to the marked condition. The results from Experiment 2 allow us to exclude an alternative explanation for the results from Experiment 1 in terms of syntactic and lexical differences between want and omdat. Given that want is a 56|Chapter 3 coordinating connective whereas omdat is a subordinating connective, the delay in processing times for want compared to omdat relations in Experiment 1 could also be interpreted as a reflection of this structural difference. Since the addition of epistemic markers in the first clause of a want relation eliminates the processing difference between want and omdat, it can be concluded that the syntactic differences between want and omdat have no independent effect on processing. After all, the addition of epistemic markers does not alter the syntactic structure of the embedded clause: both conditions with (11b), and without (11a) the ‘according to’ phrase in S1 involve coordinate clauses. (11) a. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. [Hanneke was in a hurry, want she was four stairs ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. b. Volgens Peter had Hanneke haast, want ze was vier trappen afgerend om de post te halen. [According to Peter Hanneke was in a hurry, want she was four stairs ran down to the mail get.] According to Peter, Hanneke was in a hurry, because she ran down four stairs to get the mail. In Experiments 1 and 2 we tested the effects of want and omdat in their typical context. To further assess the validity of the claim that these connectives function as an immediate signal of either a subjective or an objective relation, we conducted a third experiment in which the connectives are placed in an atypical relation: want in objective relations and omdat in subjective relations. Note that this has a different effect for objective and subjective relations. In objective relations such as (12a), the use of want leads to a subjective interpretation; S1 is interpreted as a claim. This should immediately slow the reader down, but should not cause further problems because any objective information can in principle be presented as subjective. In subjective relations, on the other hand, the use of omdat should initially be no problem, because the reader is instructed to create a CONSEQUENCE-CAUSE relation between the two clauses. However, towards the end of the relation, readers should experience severe problems when they try to interpret the relation as objective because this interpretation doesn’t make much sense. In example (12b) omdat forces the reader to interpret the second clause as the cause of the situation presented in the first clause: the fact that Hanneke ran down the stairs causes her to be in a hurry. Obviously, this results in a very implausible causal relation. Therefore, this should lead to a processing delay towards the end of the relation where the reader will try to make sense of the CONSEQUENCECAUSE interpretation. Differences in subjectivity reflected in eye-movements|57 (12) a. Hanneke had haast, want ze was vier trappen afgerend om de post te halen.

[Hanneke was in a hurry, omdat she four stairs was ran down to the mail get.] #Hanneke was in a hurry, because she ran down four stairs to get the mail. A second purpose of Experiment 3 is to assess whether the processing difference between want and omdat replicates. This effect is smaller in Experiment 2 compared to Experiment 1. Given that the presence of epistemic markers in the design is the only difference between the two experiments, this may have affected the magnitude of the effect. The presence of epistemic markers in a subset of the items may have facilitated the construction of a subjective relation in other items. However, the difference could also be caused by the fact that the effect is simply not as strong as we claim it to be. In Experiment 3 we therefore tested whether the same immediate asymmetry between want and omdat arises if we systematically vary the relations in which they are placed. In both subjective and objective relations, want should immediately induce longer processing times compared to omdat. Therefore a main effect of connective is expected to arise at the region following the connective. However, if omdat forces an objective CONSEQUENCE-CAUSE interpretation, this should cause problems in our subjective relations at the moment the reader has a complete representation of the relation, because it makes no sense. We therefore expect to find longer processing times at the end of subjective relations with omdat compared to the other conditions. 3.6 Experiment 3 3.6.1 Participants Thirty-eight undergraduate students from Utrecht University, none of which took part in Experiment 1 or 2, participated in the experiment (35 female, mean age 22 age range 18–29 years). All participants were native speakers of Dutch and were paid for their participation. 3.6.2 Materials and design The materials consisted of the same items as in Experiment 1, but we added 16 new items to obtain a total of 10 items per condition (see Appendix 2 for examples). The difference with the first experiment is that we presented both types of relations with both connectives resulting in 4 conditions. As in Experiment 1, conditions (a) and (b) are objective relations with omdat (13a) and subjective relations with want (13b) respectively. In the other two 58|Chapter 3 conditions we swapped the connectives to create objective relations with want (13c) and subjective relations with omdat (13d). (13) a.

[Hanneke was in a hurry, omdat she four stairs was ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. The 40 sets were divided over four lists, according to a Latin square design, so that each list contained only one version of a set. In addition, 60 filler items were inserted in each list. The rest of the procedure was the same as in Experiment 1. 3.6.3 Results The data were treated as in Experiment 1. All observations that were two standard deviations above or below item and subject mean for each position and condition (201 cases) were excluded from the analysis. Following these criteria we removed 0.8% of the data. Correct answers to the verification statements were given in 85% of the trials. We analyzed the same regions as in Experiment 1, defined in example (7). Again, we analyzed the logtransformations of the measures: first fixation duration, first pass reading times, regression path duration and total time. Means are reported in table 3. We performed LMER analyses on the data, with subjects and items as crossed random effects. We modeled the fixed effect of Relation (subjective vs. objective), Connective (want vs. omdat) and the interaction between these factors. At Region 1, the connective, the results revealed a main effect of Connective. Omdat was processed faster compared to want in first fixation duration (ß=-0.042, SE=0.020, t=2.05, p(MCMC)<0.05), first pass reading times (ß=-0.057, SE=0.020, t=2.78, p(MCMC)<0.01) and regression path duration (ß=-0.085, SE=0.023, t=3.67, p(MCMC)<0.001). Differences in subjectivity reflected in eye-movements|59 The same region also produced a main effect of Relation in first fixation duration (ß=0.051, SE=0.019, t= 2.62, p(MCMC)<0.01) and first pass reading times (ß=0.046, SE=0.019, t= 2.39, p(MCMC)<0.05). The connective was processed faster after a subjective first clause compared to an objective first clause. Table 3.

This region was processed faster if it followed omdat compared to want in first fixation duration (ß=-0.024, SE=0.014, t=1.71, p(MCMC)<0.05 (one-tailed)), first pass reading times (ß=0.057, SE=0.027, t=2.12, p(MCMC)<0.05) and regression path duration (ß=0.079, SE=0.023, t=3.44, p(MCMC)<0.001). Region 4, the final words of the second clause, produced a main effect of Relation in first fixation duration (ß=-0.042, SE=0.019, t= 2.20, p(MCMC)<0.05). Objective relations led to shorter first fixation durations compared to subjective relations. In regression path duration, this region produced a significant interaction between Connective and Relation (ß=0.145, SE=0.061, t=2.38, p(MCMC)<0.05). Post-hoc comparisons revealed that subjective relations with omdat led to increased processing times compared to the same relation with want (ß=0.117, SE=0.043, t=2.74, 60|Chapter 3 p(MCMC)<0.01). However, the connective made no difference in objective relations (ß=-0.024, SE=0.042, t=0.58, p(MCMC)>0.05). In total time we observed significant effects of Relation at regions 2, 3 and 4 (ß=-0.064, SE=0.024, t=2.64, p(MCMC)<0.01; ß=-0.057, SE=0.024, t=2.36, p(MCMC)<0.05; ß=-0.059, SE=0.023, t=2.57, p(MCMC)<0.05 respectively). These regions were processed faster in objective compared to subjective relations. In addition, a main effect of Connective surfaced in region 3 (ß=0.055, SE=0.024, t= 2.30, p(MCMC)<0.05). The total reading time of this region was longer in omdat relations compared to want relations. 3.6.4 Discussion The results of Experiment 3 confirm that the connectives want and omdat function as signals for the construction of a subjective and objective relation respectively. We observed longer processing times for want compared to omdat, irrespective of the exact type of causal relation in which the two connectives were presented. As in the first two experiments we observed this asymmetry at the words immediately following the connective, but on top of that, the effect also surfaced at the connective itself. These results illustrate that want triggers the same cognitive processes irrespective of the content of the preceding clause. More importantly, the results also demonstrate that omdat triggers the construction of an objective relation. As we hypothesized, the use of omdat in subjective relations leads to an initial facilitation effect compared to want, but induces problems at the end of S2 when the causal coherence relation can be fully established. At this point, readers find out that an objective interpretation makes no sense and they need more time to reread the relation, which increases the reading times. On the basis of these results we cannot tell whether readers eventually come up with a subjective representation of the relation, or whether they just end up with a nonsense relation. Either way, the results indicate that the connective initially leads into the wrong direction, resulting in serious processing difficulties at the final region of the second clause. The results in total time indicate that when readers have arrived at the end of the causal relation, it takes more time to reanalyze subjective relations compared to objective relations. This could be interpreted as a reflection of the overall complexity of the subjective relations involved. 3.7 General Discussion The purpose of the present study was to investigate the nature of the processing instructions provided by causal connectives. It is generally assumed that these markers provide important information about the unfolding discourse structure, as they signal that a causal relation is to be established between two pieces of text. However, it seems that causal Differences in subjectivity reflected in eye-movements|61 connectives do more than that. In various languages of the world the distinction between subjective and objective causal relations seems to be reflected in the usage pattern of causal connectives. We set out to assess whether such semantic-pragmatic distinctions play a role in online processing. Crucially, we were interested in the time course of such effects. As a case in point, we focused on the Dutch causal connectives omdat and want, which are considered to be prototypical markers of objective and subjective relations respectively (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009; Stukker & Sanders, 2012). We hypothesized that knowledge of these usage patterns helps language users during reading. Therefore, subjective connectives such as want are expected to induce a subjective representation whereas objective connectives such as omdat should trigger an objective representation. The three experiments presented in this chapter support this hypothesis and provide new insights into the function of causal connectives in processing. Our data reveal that the processing asymmetry between subjective and objective causal relations, as observed in English, is affected by the semantic properties of the Dutch connectives want and omdat. Recall that Traxler, Bybee, and Pickering (1997) observed longer processing times in subjective compared to objective relations at the main verb of the second clause. Given the fact that because is used in both types of relations, this is the earliest possible position at which the causal relation can be fully constructed from the content in their materials. In Dutch, this difference in processing times appears directly after the connective want is processed, or even at the connective itself (Experiment 3). At this point in the sentence the reader does not have the necessary information about the content of S2 to establish the coherence relation. Experiment 2 showed that the delay in processing times associated with want is related to a subjective interpretation of S1. If this interpretation is already marked by linguistic cues of subjectivity in the first clause, the delay at want disappears. These results show that the connective want by itself functions as a trigger for a subjective interpretation, and that this immediately affects online processing. Experiment 3 demonstrated that this effect arises independently of the information in the clauses involved. In both subjective and objective relations, want leads to an immediate processing slowdown compared to omdat. This implies that the cognitive operations responsible for these effects are induced by the properties of the connectives rather than the propositional content of the text segments. Coming back to issues raised in Chapter 2, these results reveal that the processing effects induced by want cannot be explained in terms of the plausibility of the underlying causal relation. Furthermore, the incompatibility of omdat in subjective relations, which resulted in an increase in processing times in regression path duration at the end of S2, reveals how omdat influences the processing of causal 62|Chapter 3 relations. This connective forces an objective CONSEQUENCE-CAUSE reading, which is infelicitous in our subjective relations and therefore results in a discourse garden path effect. The position of the effects of subjectivity in our Dutch experiments differs from the English results. However, we would like to emphasize that we seem to be dealing with similar cognitive processes that simply surface at different positions in the text. Recall that in both languages, the processing asymmetry between subjective and objective relations disappears if the first clause of the subjective relation is explicitly marked for its subjectivity. The main difference between the two languages is that the information encoded in the connectives differs. These findings suggest that the effects in both studies are related to subjectivity. Moreover, the observation that the use of epistemic markers in the first clause of subjective relations cancels out the early processing asymmetry between want and omdat also provides more information about the cognitive processes responsible for the effect. This result illustrates that the slowdown in unmarked subjective causals with want is not caused by syntactic or lexical differences between want and omdat, but must be related to the modification of the information in the first clause, which is exactly what epistemic markers do. Taken together, the data from the three experiments demonstrate that causal connectives are not just general devices that mark causal relations between text segments. Our findings suggest that causal connectives contribute to the immediate construction of a causal relation between two clauses (Cozijn, 2000; Cozijn et al. 2011) rather than delaying this process until the end of the second clause (Millis & Just, 1994), as discussed in the introduction of this chapter. Moreover, causal connectives provide information about rather subtle semantic-pragmatic distinctions between types of causal relations, corresponding to their usage patterns, which immediately influence online processing. Objective connectives, such as omdat, trigger the representation of an objective causal relation. Causal connectives that are typically associated with subjective relations, such as want, trigger the representation of someone’s belief or opinion, be it from the author, speaker or any other person whose reasoning is presented in the discourse. As a result, it functions as a cue to readers that the information is to be interpreted as a mental state and not as a fact or event in the world. Future research will have to establish whether the processing pattern observed in Dutch is generalizable to other languages that have equally specialized connectives. Different theoretical explanations could explain the observed disadvantage in processing times for subjective connectives, and subjective causal relations in general. In what follows, we discuss two theories from diverging frameworks. Differences in subjectivity reflected in eye-movements|63 From a linguistic perspective, it could be argued that subjective relations are more complex than objective relations, simply because they contain more information at the propositional level. Subjective relations possibly require the representation of an additional proposition concerning the validity or truthfulness of S1, which could be described in terms of an ‘X thinks / says’ component (De Smet & Verstraete, 2006; Ross, 1970; Rutherford, 1970. If the context preceding a connective expressing a subjective relation does not already trigger such a proposition, as is the case in the unmarked subjective relations in our experiment, encountering a connective such as want may trigger the construction of such a proposition. In case of underspecified connectives, such as because, this representation has to be established from the content of the relation. If however, the additional information is already marked in S1, the second clause is processed smoothly. A similar explanation is put forward in Traxler, Sanford, Aked, and Moxey (1997), who propose that the processing difficulty observed in subjective causal relations is caused by the fact that it has not been made clear that S1 needs to be interpreted as a psychological event (as opposed to an objective interpretation of the state of affairs in the real world). As a result, S1 needs to be reanalyzed as such. The authors therefore treat the effects of subjectivity along the lines of the garden path effects associated with reduced relatives and reduced complements (Ferreira & Henderson, 1990; Trueswell, Tanenhaus, & Garnsey, 1994; Trueswell, Tanenhaus, & Kello, 1993). A different way to account for the processing effects is by relying on discourse theories on perspective. Subjective causal relations differ from objective relations in that they involve a change in perspective, because the interpretation of the claim or conclusion has to be related to the speaker’s point of view or mental space (Fauconnier, 1994; Sanders, Sanders, & Sweetser, 2009, 2011). Theories such as the Deictic Shift Perspective (Segal & Duchan, 1997; Segal, Duchan, & Scott, 1991) predict that such perspective changes induce processing difficulties. According to this theory, readers experience a narrative world by following the perspective in the story. Crucial to this theory is the ‘Principle of continuity’, which assumes a general bias to process information in a continuous fashion. Changes in the discourse structure are associated with a processing cost; therefore this principle has been adopted to account for the processing effects that have been observed with topic shifts and temporal discontinuity (Bestgen & Costermans 1994; Bestgen & Vonk, 2000; Zwaan, 1996). Even though it is debatable whether sentence pairs constitute a narrative, all subjective relations that do not contain subjectivity markers in S1 involve a perspective change. In the absence of other markers of subjectivity, the first clauses of these relations are presented as objective observations of events taking place in the world. However, the connective want makes clear that the reader has 64|Chapter 3 to shift that perspective to the subjective perspective of the speaker, which could explain the processing difficulty associated with this connective. Indeed, subjective connectives such as want are claimed to function as perspective markers (Verhagen, 2005). In relations with more general connectives such as because, perspective shifts are marked by the propositional content of the second clause, at the moment the reader has all the necessary information to establish the subjective relation. If the first clause of a subjective relation already marks the speaker’s perspective, by markers such as perhaps, or the subjective perspective of the protagonist, as in the ‘according to’ condition in Experiment 2, continuity is maintained. On the basis of the empirical data so far we cannot yet determine which of these theories most adequately accounts for the disadvantage in processing time for subjective causal relations. Whether it consists of a local reanalysis of the proposition in the first clause, or whether it is related to the maintenance of perspective, could be tested in an experimental setup with larger contexts. Following the perspective approach, a contextual manipulation of perspective should eliminate a perspective shift at encountering a subjective connective such as want. If such a manipulation cancels out the processing difficulty at want, this would provide evidence for the Deictic Shift Perspective. A propositional account, on the other hand, predicts that this manipulation would not solve the problem because a manipulation of perspective in the context does not explicitly mark the first clause of the relation as a mental state. In any case, both explanations have one thing in common which is essential for any theory on the processing and representation of subjective causal connectives and subjective relations in general. These relations require the representation of additional information related to reasoning processes. The experimental data on English and Dutch show that this representation can be established either by epistemic markers, such as maybe and John thinks, or by subjective connectives such as want. Further research is required to assess what this representation consists of and how it relates to general cognition. Chapter 4 Processing subjective causal relations: The role of contextual versus linguistic signals of speaker involvement. 4.1 Introduction Language is used for communication. In order for communication to be successful, it is not enough to process the individual pieces of information in the linguistic input. It is a widely shared assumption that establishing the relations between those pieces is an essential part of communication. Crucially, language comprehension also involves an evaluation of whether the conveyed information corresponds to our world knowledge: whether that information is true, false, possible or plausible (Johnson–Laird, 1983; Noordman & De Blijzer, 2000). Therefore, language users need to be able to distinguish between utterances that describe actual events or situations in the real world, and utterances that convey someone else’s belief, opinion, or evaluation of these events. Say, for example, you are watching a soccer game in a bar and you overhear a heated discussion in which someone yells (1): (1) That referee needs to go look for a new job! Given the circumstances in which this utterance is produced, it is pretty unlikely that you will believe that the discussion is about a referee that is actually looking for a new job. Instead, the discourse and other non verbal cues (shouting, hand gestures, angry faces) will probably lead to the interpretation that the sentence “That referee needs to go look for a new job” is not to be interpreted literally, but conveys the speaker’s (negative) opinion about this referee. In that case, the utterance could most likely continue as in (2): (2) It was clearly offside. Even though in this example the correct interpretation seems rather obvious, under different circumstances it is possible to continue the sentence as in (3): (3) His contract will not be extended. What these examples illustrate is that in everyday communication, language users need to be able to distinguish between these different interpretations; between clauses that express factual situations in the real world, and those that convey another person’s opinion, belief or conclusion 66|Chapter 4 about those situations. At first glance, this seems like a simple task to perform. And of course, information about some person we do not know or care about may not need to be evaluated with great care. Indeed, we probably do not go about verifying the status of every utterance we hear. Yet, this does not mean that the processes underlying these decisions are executed without any effort or ambiguity. As the causal continuations in (2) and (3) illustrate, the status of the sentence in (1) can vary as a function of these continuations. In combination with (2), we are dealing with a CLAIMARGUMENT relation, whereas the continuation in (3) results in a CONSEQUENCE-CAUSE relation. As we have seen in Chapters 2 and 3, the distinction between these types of relations is also referred to as subjective versus objective relations (e.g., Degand & Pander Maat, 2003; Pander Maat & Degand, 2001; Pander Maat & Sanders, 2001). Other labels that have been used to describe these relations are semantic versus pragmatic (Sanders, Spooren, & Noordman, 1992; Van Dijk, 1979) internal versus external (Halliday & Hasan, 1976), or content versus epistemic relations (Sweetser, 1990). In objective causal relations, the speaker is describing the situation in S1 and S2 as being causally related in the real world (Pander Maat & Sanders, 2000), the speaker is ‘just reporting’ (Sanders, Sanders, & Sweetser, 2012, p.6). Subjective relations, on the other hand, involve reasoning. The speaker is presenting a conclusion or a claim on the basis of some evidence in the real world. On the basis of the conceptual difference between these two types of causal relations, subjective causal relations are claimed to be more complex than objective causal relations (Noordman & De Blijzer, 2000; Sanders, Spooren, & Noordman, 1992; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997). Traxler, Bybee, and Pickering (1997) found that subjective causal relations (4b) lead to longer processing times compared to objective causal relations (4a). This effect appeared at the words didn’t score in the example below, which is the position in the sentence where the reader can infer the type of causal relation from the content. (4) a. The goalkeeper won the game because the other team didn’t score any goals. b. The goalkeeper knew how to play the game because the other team didn’t score any goals. In English, both subjective and objective backward causal relations can be expressed by because (e.g. Couper-Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990), this connective can therefore not be used as a cue to establish the exact type of causal relation. In Dutch, however, these types of relations are typically expressed by two different causal connectives: want is a prototypical marker of subjective Contextual versus linguistic signals of speaker involvement|67 CLAIM-ARGUMENT relations (5b) whereas omdat is a prototypical marker of objective CONSEQUENCE-CAUSE relations (5a) (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009; submitted; Verhagen, 2005). (5) a. Die scheidsrechter moet ander werk gaan zoeken omdat zijn contract niet wordt verlengd. That referee needs to go look for a new job omdat his contract will not be extended. b. Die scheidsrechter moet ander werk gaan zoeken want het was duidelijk buitenspel. That referee needs to go look for a new job want it was clearly offside. The results presented in Chapter 3 reveal that the Dutch connectives want and omdat provide immediate instructions about the type of causal relation they mark. In a set of eye-tracking experiments involving Dutch objective (6a) and subjective (6b) causal relations, we demonstrated that the subjective connective want induces longer processing times compared to the more objective connective omdat. (6) a. Hanneke was buiten adem, omdat ze vier trappen was afgerend om de post te halen. [Hanneke was out of breath, omdat she four stairs was ran down to the mail get.] Hanneke was out of breath, because she ran down four stairs to get the mail. b. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. [Hanneke was in a hurry, want she was four stairs ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. This effect arose at the connective itself and at the first words immediately following it. At this point in the sentence, readers do not yet have enough information to construct the causal relation from the content, which shows that the effect is caused by the semantic-pragmatic properties of the connectives. We proposed that omdat triggers the representation of an objective CONSEQUENCE-CAUSE relation, whereas want triggers the representation of a subjective CLAIM-ARGUMENT relation. If this hypothesis is on the right track, it is expected that readers experience difficulties when the connective leads into the wrong direction. This is confirmed by the results from Experiment 3 in Chapter 3. When both connectives are placed in a subjective relation that does not allow for a CONSEQUENCE-CAUSE interpretation such as (7), omdat leads to longer processing times at the end of the second clause. (7) #Hanneke had haast, omdat ze vier trappen was afgerend om de post te halen. 68|Chapter 4 [Hanneke was in a hurry, omdat she four stairs was ran down to the mail get.] #Hanneke was in a hurry, because she ran down four stairs to get the mail. Even though the position of the effect differs in the two languages, the effects associated with subjective causal relations in English and Dutch reflect similar cognitive processes. In both languages, a disadvantage in processing time arises at the point where it becomes clear that S1 represents someone’s reasoning rather than an objective consequence. In English, this information is derived by the propositional content of the second clause, which makes clear that the relation is subjective. In Dutch, this information is cued by the connective want. That these effects reflect similar cognitive processes in both languages can be derived from the fact that both effects are canceled out when the first clause of the causal relation contains explicit cues about the status of S1 as a claim. In a set of clause-by-clause self-paced reading experiments, Traxler, Sanford, Aked, and Moxey (1997) show that the delay in processing times for subjective compared to objective causal relations disappears if the first clause of the subjective causal relation is marked by modal expressions such as perhaps and maybe, or the mental state predicate John thinks (8). These markers make clear that the first clause is to be taken as someone’s belief, claim, or conclusion, and thus explicitly mark the information as being subjective. (8) John thinks the goalkeeper knew how to play the game because the other team didn’t score any goals. Similar results were obtained in Experiment 2 in Chapter 3. We found that the immediate disadvantage in processing time for want compared to omdat is canceled out if the first clause of the relation is preceded by the mental state predicate according to Peter (9). (9) Volgens Peter had Hanneke haast, want ze was vier trappen afgerend om de post te halen. [According to Peter Hanneke was in a hurry, want she was four stairs ran down to the mail get.] According to Peter, Hanneke was in a hurry, because she ran down four stairs to get the mail. These experiments reveal that when readers are explicitly cued about the status of S1 as a claim or conclusion, the delay in processing time for subjective compared to objective causal relations in both English and Dutch is canceled out. This shows that the relative complexity of these relations has to be related to the representation of S1 as someone’s reasoning, rather than an actual event in the world. Furthermore, these studies illustrate that the construction of this representation, as triggered by subjective connectives Contextual versus linguistic signals of speaker involvement|69 such as want, comes at a processing cost. However, when the construction of this representation is already explicitly cued in the first clause of the causal relation, the rest of the subjective relation is processed smoothly. Up to now, we have discussed CLAIM-ARGUMENT relations. However, language users encounter claims in many different kinds of linguistic contexts. The fundamental question is how do language users recognize the special status of a sentence as a claim? And what are the mechanisms underlying the processing of subjective causal relations? As discussed in Chapter 2, the difference between objective and subjective causal relations has been described in terms of speaker involvement. Speaker involvement is defined as the degree to which a thinking subject, which can be the speaker, author, or any person whose reasoning is presented, is involved in the construal of the causal relation (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000; Pit, 2003; Stukker, Sanders & Verhagen, 2009), thereby taking responsibility for the presented information. In the current study, we will explore whether contextual cues of speaker involvement affect the processing asymmetry between subjective and objective causal relations in Dutch, as marked by want and omdat respectively. To be more specific, the question is: does a text have to make explicit that a given sentence is someone’s claim, to overcome the disadvantage in processing time for subjective compared to objective causal relations? Or do contextual cues that imply that the text is written from the author’s perspective, in which he or she might be claiming things, have the same effect? In other words, do we need to know that someone is claiming, or does S1 have to be explicitly marked as a claim? 4.2 Subjectivity from a mental space perspective Examples (1) to (3) suggest that in everyday communication the representation of claims and beliefs can be easily derived from the (nonlinguistic) context. Indeed, there are global means to mark the speaker’s subjective involvement in a discourse, for example, by an argumentative context that makes clear that the presented information is to be interpreted from the speaker’s point of view. It is, however, unclear whether linguistic contextual cues of speaker involvement also cancel out the disadvantage in processing time for subjective over objective causal relations as marked by want and omdat. A cognitive theoretical framework that might provide insights in this matter is Mental Spaces Theory (MST) (Fauconnier, 1994). Mental spaces are conceived as conceptual spaces in which information bound to time, space, and person is represented relative to the here and now. As such “They organize the processes that take place behind the scenes as we think and talk” (Fauconnier, 1998, p.151). According to MST, language users build, and 70|Chapter 4 constantly update, a network of mental spaces when they communicate. Within this theory, a special function has been ascribed to linguistic signals that set up the construction of specific mental spaces, so-called space builders. For example, in Fauconnier’s (1998) example in (10), the expression Max thought functions as a space builder because it sets up the mental space that represents Max’s thoughts. (10) Max thought the winner received $100. Subjective connectives such as want have also been proposed to function as space builders; they trigger the setup of the mental space of the relevant thinking subject, be it the speaker, author, or a third person character in a story, in which the causal relation can be interpreted (Sanders, Sanders, & Sweetser, 2009, 2012; Verhagen, 2005). Even though MST is not developed to make specific predictions about online discourse processing, this theory could be used to formulate hypotheses about the processing effects associated with subjective causal relations. On the basis of MST it could be argued that the cognitive complexity of representing someone’s reasoning is related to the construction of the relevant mental space for interpretation. If this operation explains the longer processing times for subjective compared to objective causal relations, it follows that this effect should be canceled out if the context preceding the causal relation contains (linguistic) elements that already provide the required mental space for interpretation. Indeed, contextual cues of speaker involvement have been shown to influence the offline interpretation of causal relations. Sanders (1997) embedded causal relations that were ambiguous between a subjective and an objective interpretation in either an argumentative or a descriptive version of a text. Participants were asked to choose the best fitting paraphrase of the relation from a list. The results revealed that the interpretation of ambiguous causal relations is affected by context type. Descriptive texts lead to more objective interpretations while argumentative texts lead to more subjective interpretations. These results illustrate that an argumentative context can guide the offline interpretation of ambiguous causal relations without a causal connective. The remaining question is whether this type of information prepares the reader for the representation of claims in the upcoming text in such a way that it facilitates the online processing of CLAIM-ARGUMENT relations. One way to answer that question is by manipulating evaluative markers in the context preceding want and omdat relations. Evaluation is referred to as “the broad cover term for the expression of the speaker or writer’s attitude or stance towards, viewpoint on, or feelings about the entities or propositions that he or she is talking about” (Thompson & Hunston, 2000, p.5), similar to the notion of stance (Biber & Finegan, 1988). Contextual versus linguistic signals of speaker involvement|71 In this study we particularly focus on evaluative adverbs and adjectives such as terribly, fantastic and ridiculous in written text. Such expressions make clear that the author is emotionally involved in the matter under discussion. Therefore, these markers are expected to function as cues to the reader that the text is to be interpreted from the author’s perspective; they inform the reader that someone is claiming. Yet, they do not provide explicit cues for the interpretation of specific clauses in the text as being claims or conclusions, as part of a chain of reasoning. If the representation of claims as marked by want is related to the construction of the required mental space for interpretation, the processing of this connective should be sensitive to the presence of space builders in the discourse context. Therefore, the processing asymmetry between want and omdat, as reported in Chapter 3, should be smaller, or even canceled out, if the preceding context already provides information about the author’s involvement in the text. Neutral contexts, without such markers, should lead to a replication of the processing asymmetry between these two connectives. 4.3 Experiment 1 4.3.1 Participants 39 Undergraduate students from Utrecht University participated in the experiment (35 female, mean age 22.3 age range 18–35 years). All participants were native speakers of Dutch and were paid for their participation. 4.3.2 Materials and design We created 36 sets of adapted news items on various topics, which were all approximately one paragraph long. Two factors were manipulated: Context (neutral versus subjective) and Relation (want versus omdat relations). All omdat relations are CONSEQUENCE-CAUSE relations such as (11b). All want relations are CLAIM-ARGUMENT relations in which the second clause cannot be interpreted as the cause of the situation in the first clause (11a) (see Appendix 3 for more examples). Both want and omdat relations have the same first clause, which means that this first sentence is in principle ambiguous between a claim (followed by an argument) and a consequence (followed by a cause). Because want is a coordinating connective and omdat a subordinating connective, there is a difference in the word order of the embedded clauses. In Dutch coordinate clauses the finite verb is in second position while subordinate clauses require verb final word order. However, we designed the items in such a way that the first words following the connective were the same in both want and omdat relations. This allows us to make a comparison between want and omdat relations directly after the connectives are 72|Chapter 4 processed, which is the position where we observed the processing difference between want and omdat in Chapter 3. After this segment, the content of the want and omdat relations starts to diverge, expressing either a CONSEQUENCE-CAUSE or CLAIM-ARGUMENT relation. Therefore, the processing times of the rest of the want and omdat relations cannot be directly compared, since they contain different words. Care was taken that both types of relations fit into the global discourse structure to create natural texts in all conditions. (11) a. Het huidige niveau van de studenten is laag want slechts de helft haalt een voldoende voor rekenen en taal.

Het huidige niveau van de studenten is laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. The students' current skill level is low omdat only half of the teaching hours are dedicated to maths and language. Subjective contexts were created by adding evaluative adverbs (such as horribly, amazingly), adjectives (ridiculous, stupid, fantastic) and discourseoriented adverbs (of course, really) to the title and the text preceding the causal relation. These markers reveal the emotional involvement of the author with respect to the content, which informs the reader that the text is to be interpreted from the author’s point of view. In that respect, our subjective contexts resemble letters to the editors of newspapers (Pounds, 2005). The final sentence of the text was the same in both contexts. An example of an experimental item is given in (12). (12) a.

We made sure that the connective was never at the end or beginning of a line. Because the majority of the causal relations were too long to fit on a single line, we placed the final words of the causal relation on the subsequent line. There was 74|Chapter 4 considerable variance with respect to the layout of the texts. However, length differences between the target line, containing the second clause of the causal relation, and the lines preceding and following it were kept to a minimum to avoid effects due to systematic differences in visual presentation. 54 Filler news items were added to the materials. These items covered a range of topics and had the same length as the test items but contained no causal relations. 4.3.3 Pretest An offline judgment test was performed to check whether our manipulation of speaker involvement was successful. Two lists were created, containing either the subjective or the neutral version of a text. Each text was cut off after the first clause of the causal relation, directly before the connective, so that the degree of subjectivity of the connective could not influence the judgments. 19 Students of Utrecht University participated in the judgment task. These participants did not take part in any of the other experiments in this study. Because it is difficult, and maybe even impossible, to judge the degree of speaker involvement, we asked our participants to judge the persuasive and the informative intent of the author on a 7-point Likert scale. We reasoned that if readers are sensitive to the presence of evaluative markers in the subjective texts as an indication of the author’s point of view on the matter under discussion, these texts should score higher on persuasive intent than the neutral variants. The judgments were analyzed using Linear Mixed Effects Regressions (LMER) analyses (Baayen, 2008), with subjects and items as crossed random effects and Condition (subjective versus neutral) as fixed factor. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). The results indicate that the context influenced readers’ perception of the author’s intentions. Subjective contexts received a higher score on persuasive intent compared to neutral contexts (4.32 (1.88) versus 2.77 (1.65) respectively) (ß=1.57, SE=0.11, t=13.71, p(MCMC)<0.001). Neutral contexts received a higher score on informative intent compared to subjective contexts (6.07 (1.02) versus 5.31 (1.46) respectively) (ß=0.78, SE=0.07, t=10.42, p(MCMC)<0.001). These results indicate that readers are sensitive to our manipulation of speaker involvement. 4.3.4 Apparatus and procedure Eye movements were recorded with a desktop-mounted EyeLink 1000 eyetracker, controled by FEP software (Veenker, 2006), which samples the right eye at 500Hz. The system has an eye position tracking range of 32 degrees horizontally and 25 degrees vertically, with a gaze position accuracy of 0.5 degrees. The materials were presented on a 19-inch computer screen at a viewing distance of approximately 60 centimeters. Before the experiment Contextual versus linguistic signals of speaker involvement|75 started, participants were informed about the procedure and the experimenter made sure the participant was comfortably seated. All participants were informed that the experiment consisted of newspaper texts and they were asked not to move their heads or blink excessively during the experiment. Each experiment started with a thirteen-point calibration procedure followed by a validation procedure, which was repeated before each block. The experiment started with a practice trial of 3 items. 4.3.5 Results Example (13) illustrates how the items were divided into regions. Again, line breaks are indicated by a backslash. The title and the text preceding the causal relation will not be discussed because these parts of the text contain more words in subjective compared to neutral contexts. Region 1 consists of the first part of S1 and Region 2 contains the rest of S1 after the line break. Region 3 is the connective and Region 4 comprises the target region, in most cases the subject of S2 or a prepositional phrase. Region 5 is the point from which want and omdat relations start to diverge and contains the main verb. Region 6 is the final region of the target line and region 7 contains the last words of the causal relation on the next line. The final region comprises the last sentence of the text.

Following these criteria we removed 0.8% of the data. We computed the following measures: first pass reading times, right-bounded time, regression path duration, and total reading time. First pass reading times is what Rayner and Duffy (1986) call gaze duration for single words and consists of all fixations within a region (including saccades) before moving into a forward or a backward direction. Right-bounded time (or total gaze duration) sums all fixations within a region before moving on progressively. This measure consists of first pass reading times, including additional fixations that follow regressive eye-movements. Regression path 76|Chapter 4 duration (Konieczny, Hemforth, Scheepers, & Strube, 1997) consists of all fixations on a region before passing on in a forward direction, including rereading of previous material. Total reading time is the Total time spent at a region. This measure includes the time required for reanalysis when a piece of information is not completely processed during the first reading (Rayner & Sereno, 1994). Means are reported in Table 1. We performed Linear Mixed Effects Regression analyses (LMER) (Baayen, 2008) on the data, with subjects and items as crossed random effects and Relation (want vs. omdat), Context (subjective vs. neutral) and the interaction between these two as fixed effects. Eye-tracking data typically have a lot of missing values, especially if the regions of interest are short. However, multilevel analyses such as LMER are robust against missing data (Quené & van den Bergh, 2004). Log-transformations were performed on the data in order to meet the normality requirements of linear modeling. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). If the processing asymmetry between want and omdat, as observed in Chapter 3, is related to processes involved in the construction of the mental space of the thinking subject, this effect should be canceled out by evaluative markers that already trigger this mental space in the context preceding the relations. In that case we expect an interaction effect between Relation and Context at the words following the connective (Region 4). This region should be processed faster after omdat compared to want in neutral contexts. In subjective contexts, however, this difference is expected to be smaller, or even canceled out. Main effect Relation (want vs. omdat) Want leads to longer processing times compared to omdat at several positions in the sentence. At the connective (Region 3) this effect surfaced in regression path duration (ß=0.072, SE=0.030, t=2.40, p(MCMC)<0.05) At the words immediately following the connective (Region 4) we observed this effect in first pass reading times (ß=0.067, SE=0.023, t=2.97, p(MCMC)<0.01) regression path duration (ß=0.077, SE=0.024, t=3.13, p(MCMC)<0.001), right-bounded time (ß=0.065, SE=0.022, t=2.97, p(MCMC)<0.01) and total time (ß= 0.070, SE=0.025, t=2.81, p(MCMC)<0.01). At Region 8, the final sentence of the text, this effect surfaced in rightbounded time (ß=0.055, SE=0.012, t=4.40, p(MCMC)<0.001), regression path duration (ß=0.040, SE=0.014, t=2.78, p(MCMC)<0.01) and total time (ß= 0.055, SE=0.012, t=4.40, p(MCMC)<0.001). At Region 7, the final words of the target sentence, we observed a main effect of Relation in the opposite direction. Want lead to faster processing times compared to omdat in first pass reading times (ß=-0.076, SE=0.021, Contextual versus linguistic signals of speaker involvement|77 t=3.57, p(MCMC)<0.001), right-bounded time (ß=-0.069, SE=0.022, t=3.17, p(MCMC)<0.01), regression path duration (ß=-0.06194, SE=0.025, t=2.45, p(MCMC)<0.05) and total time (ß=-0.086, SE=0.022, t=3.84, p(MCMC)<0.001. However, because this region contains different words in the two types of relations, this effect is not interpretable. Main effects of Context (subjective vs. neutral) Main effects of Context surfaced at the first part of S1 (Region 1). Subjective contexts produced longer fixation times compared to neutral contexts in right-bounded time (ß=0.040, SE=0.017, t=2.32, p(MCMC)<0.05), regression path duration (ß=0.049, SE=0.019, t=2.57, p(MCMC)<0.05), and total time (ß=0.055, SE=0.018, t=2.97, p(MCMC)<0.01). At Region 7, the final words of the relations, we observed the opposite effect. This region was processed faster in subjective contexts compared to neutral contexts in first pass reading times (ß=-0.052, SE=0.021, t=2.46, p(MCMC)<0.05), right-bounded time (ß=-0.051, SE=0.021, t=2.37, p(MCMC)<0.05) and total time (ß=-0.045, SE=0.022, t=2.03, p(MCMC)<0.05). Region 8, the final sentence of the text, produced the same effect as observed in Region 1. Subjective contexts produced longer fixation times compared to neutral contexts in right-bounded time (ß=0.032, SE=0.012, t=2.54, p(MCMC)<0.05), regression path duration (ß=0.031, SE=0.014, t=2.15, p(MCMC)<0.05) and total time (ß=0.032, SE=0.012, t=2.54, p(MCMC)<0.05). Interaction Relation * Context At Region 6 we observed a significant interaction between Relation and Context in first pass reading times (ß=-0.095, SE=0.047, t=2.04, p(MCMC)<0.05). The end of the target line in omdat relations was read faster in neutral contexts compared to subjective contexts (ß=-0.066, SE=0.032, t=2.02, p(MCMC)<0.05). In want relations, however, there was no difference between the two contexts (ß=-0.026, SE=0.030, t=0.86).

Mean first pass reading times (FP), right-bounded time (RB), regression path duration (RP) and total reading time (TT) by Context (subjective vs. neutral) and Relation (want vs. omdat) per Region in Experiment 1. 78|Chapter 4 Contextual versus linguistic signals of speaker involvement|79 4.3.6 Discussion In Experiment 1 we manipulated evaluative adverbs and adjectives (ridiculous, horribly, fantastic etc.) which all make clear that the author is emotionally involved in the matter under discussion. Therefore these markers should function as signals to the reader that the information is presented from the author’s point of view, even before the causal relation is processed. The results of Experiment 1 reveal that this manipulation has no effect on the processing of want versus omdat. We replicated the disadvantage in processing time for want compared to omdat at the words following the connective, as reported in Chapter 3, in both subjective and neutral contexts. Up to this point in our test items, both types of relations contain exactly the same words (except for the connective). This confirms that the effect is induced by the connective itself rather than the content of the relations. In addition, the same asymmetry already arises at the connective, which provides further evidence for the claim that we are dealing with processes induced by an inherent difference between want and omdat. These results demonstrate that the asymmetry between want and omdat is not limited to sentences in isolation, but also surfaces in larger contexts. Crucially, there was no interaction between Context and Relation at this point in the relation. The presence of evaluative markers in the context preceding the causal relation had no influence on the immediate processing asymmetry between want and omdat. Providing the author’s perspective by means of these markers is clearly not enough to overcome the processing difficulty that arises at want, which suggests that this effect is not related to the construction of mental spaces, or a general notion of speaker involvement. But did subjectivity of the context have no effect at all? After all, the offline tests of our materials did reveal that readers are sensitive to our manipulation of speaker involvement. Subjective contexts received a higher score on persuasive intent, but a lower score on informative intent compared to neutral contexts. In addition, the online results show that this manipulation affects readers’ overall processing strategies. Adding an argumentative flavor to the context preceding the causal relation slows down the processing of subsequent information. Region 1, comprising the main part of S1, contains the same words in all conditions but produces longer reading times if placed in subjective contexts compared to neutral contexts. A similar pattern arises in total reading time at the final sentence of the text, which is also the same in subjective and neutral contexts. This measure captures the time required for reanalysis when a piece of information is not completely processed during the first reading (Rayner & Sereno, 1994). Thus, readers spent more time rereading the final sentence in subjective compared to neutral texts. In the general discussion we will consider this effect in more detail. For now it suffices to know that our manipulation of speaker involvement was not too subtle to be noticed. 80|Chapter 4 The opposite effect surfaced at Region 7, which comprises the final words of the relation. This region was processed faster in subjective compared to neutral texts. Given that region 7 is associated with substantial length differences, varying from 1 to over 4 words, it is difficult to interpret any effect that surfaces at this region. Even though we did not observe any significant interactions at this position, on the basis of the mean reading times in Table 1 it may be the case that the want relations are mainly responsible for this effect. These relations led to faster processing times in subjective contexts compared to all other conditions. The mean reading times in omdat relations in subjective contexts, however, are not faster than the mean reading times for want and omdat relations in neutral contexts. This suggests that at this point in the sentence the match between the context and the relation influences the processing of want relations. At the previous region, the end of the target line, a similar pattern surfaced in omdat relations. This region did produce a significant interaction between Context and Relation in first pass reading times. Neutral contexts led to faster processing times in omdat relations compared to subjective contexts. These results suggest that neutral contexts facilitate the processing of omdat relations at Region 6, whereas subjective contexts facilitate the processing of want relations at Region 7. These effects could be interpreted as a reflection of wrap-up effects that surface at different positions in the text, depending on the type of relation (e.g. Just & Carpenter 1980; Kennedy, Murray, Jennings, & Reid, 1989; Rayner, Kambe, & Duffy, 2000). And indeed, as noted before, want- and omdat-relations contain different words in S2. However, since we were not anticipating any wrap-up effects, the items were not designed to capture them. As a result, the final regions of the relations were not controled for their length, distribution of information, and the way in which they have been segmented. Therefore, before we can draw any conclusions about these patterns, we need to reduce the differences between want- and omdat- relations to test whether they replicate. Interestingly, the type of relation also influenced the processing of the final sentence of the text. This region produced longer total reading times after want relations compared to omdat relations. This indicates that, compared to objective relations, readers engage in additional cognitive processes immediately after a subjective relation is completed. Not only do readers experience immediate processing difficulties when they are faced with a CLAIM-ARGUMENT relation, they also need more time to evaluate that relation after it is processed. Overall, the results from Experiment 1 reveal that there is no indication that the longer processing times for want compared to omdat can be explained by the necessity of setting up the mental space of the thinking subject. It is not enough to know that the text is presented from the author’s point of view to overcome the disadvantage in processing time for want Contextual versus linguistic signals of speaker involvement|81 compared to omdat. This suggests that language users need more explicit cues about the status of a sentence as a claim. But how specific must these cues be? The results reported in Traxler, Sanford, Aked, and Moxey (1997), and our results from Experiment 2 in Chapter 3 demonstrate that modal sentence adverbs such as perhaps and mental state predicates such as John thinks and according to John in S1 cancel out the processing difference between subjective and objective causal relations. In addition to being local cues of subjectivity, these markers have scope over the entire sentence. In (14) the phrase Volgens Jan modifies the entire clause that follows as something that Jan claims. (14) [Volgens Jan [is het huidige niveau van de studenten laag] ] want [Y] [According to Jan [the students' current skill level is low] ] because [Y] Therefore, there may be two ways in which the status of S1 as a claim could be derived. Readers either rely on reference to the relevant thinking subject within S1, or on explicit markers that modify S1 as a whole as someone’s reasoning. A way to disentangle these factors is by testing how evaluative adjectives and adverbs as non-sentence modifiers within S1 affect the processing of subjective causal relations. As discussed in the introduction, these markers inform the reader that the author is emotionally committed to the content of the proposition, and therefore make clear that the utterance is to be interpreted from the author’s perspective. Rather than explicitly marking S1 as a claim, they make S1 argumentative. Indeed, evaluative adverbs such as ridiculously in (15) do not affect the status of the entire sentence; they only have scope over a subpart. Note that evaluative adverbs can be used as sentence modifiers (see 16). In the present study, however, we only manipulate adverbs as non-sentence modifiers. (15) Het huidige niveau van de studenten is [belachelijk [laag]]. The students' current skill level is [ridiculously [low]] (16) Het is belachelijk [dat het huidige niveau van de studenten laag is]. It is ridiculous [that the students' current skill level is low]. If language users can derive the status of S1 as a claim by markers of speaker involvement within that sentence, we expect that the presence of evaluative markers within S1 cancels out the processing difference between want and omdat. If, however, this status can only be derived by linguistic devices that modify S1 as a whole, we expect that the presence of evaluative markers within S1 will not cancel out the disadvantage in processing time for want. 82|Chapter 4 A second issue that needs to be resolved is to verify whether the interaction effect between Context and Relation that surfaced towards the end of the causal relations is valid. We tentatively interpreted this pattern as a match/mismatch effect between Relation and Context that is spread out over two consecutive regions. However, as explained before, we did not design appropriate items to be able to measure such effects. We therefore need to reduce the differences between want and omdat relations with respect to their length and distribution of information to test whether it replicates. 4.4 Experiment 2 4.4.1 Participants 39 Undergraduate students from Utrecht University participated in the experiment (34 female, mean age 22,4 age range 18–28 years). These participants did not take part in any of the other experiments in this study. All participants were native speakers of Dutch and were paid for their participation. 4.4.2 Materials and design The materials consisted of the 36 items from Experiment 1, which were slightly adapted (see Appendix 3). The conditions in the neutral contexts (17 a and b) are the same as in Experiment 1. We manipulated the subjective conditions by adding evaluative markers to the first clause of want and omdat relations (See example (17c) and (17d) respectively). In addition, we adjusted a subset of the items to reduce the length differences between want and omdat relations. Line breaks in the target line were placed earlier compared to Experiment 1, at a point in the sentence where there would not yet be enough information available to construct the causal relation (see example 17 for an illustration of the visual presentation). In doing so, we tried to avoid wrap-up effects triggered by the line break (Kennedy et al., 1989) so that we would be able to capture these effects at the final region on the next line. The rest of the design and procedure were the same as in Experiment 1. (17) a.

These participants did not take part in any of the other experiments in this study. They were asked to judge the persuasive and the informative intent of the author on a 7-point Likert scale. The results replicate the findings of the judgment task in Experiment 1. Subjective texts received a higher score on persuasive intent compared to neutral texts (5.19 (1.60) versus 3.06 (1.79) respectively) (ß=2.14, SE=0.12, t=17.67, p(MCMC)<0.001). Neutral texts received a higher score on informative intent compared to subjective texts (5.98 (1.20) versus 4.67 (1.44) respectively) (ß=1.32, SE=0.09, t=14.70, p(MCMC)<0.001). These results indicate that, as in Experiment 1, readers are sensitive to our manipulation of speaker involvement. 4.4.4 Results The data were treated as in Experiment 1. All observations that were two standard deviations above or below item and subject mean for each position and condition (348 cases) were excluded from the analysis. Following these criteria we removed 0.9% of the data. Again, we analyzed the logtransformations of the measures: first pass reading times, right-bounded time, regression path duration, and total reading time. Means are reported in Table 2. As in Experiment 1, we will not discuss the title and the text preceding the causal relation because these parts of the text contain more words in subjective compared to neutral contexts. There were some slight changes with respect to the segmentation of the items. Therefore, not all regions are directly comparable to Experiment 1. Example (18) illustrates how the texts were divided into regions. Again, line breaks are indicated by a backslash. Because the position of the evaluative markers in S1 varied, we had to analyze this sentence as one text region. Regions 2 and 3 consist of the connective and the target region respectively and are the same as in Experiment 1. Region 4 is the final region of the target line and is the point from which want and omdat relations start to diverge. This region is shorter compared to Experiment 1 because we wanted to avoid early wrap-up effects triggered by the line break (Kennedy et al. 1989). Region 5 consists of the final words of the relation and is longer compared to Experiment 1. Region 6 is the final sentence of the text, which is the same in all conditions.

Below we will discuss the main effects of these two factors throughout the text. Main effects Relation Region 3, the words following the connective, was processed faster when it followed omdat than when it followed want. This effect surfaced in first pass reading times (ß=0.047, SE=0.024, t=1.99, p(MCMC)<0.05), total time (ß=0.062, SE=0.027, t=2.31, p(MCMC)<0.05), and marginally in rightbounded time (ß=0.044, SE=0.023, t=1.95, p(MCMC)=0.05) and regression path duration (ß=0.048, SE=0.025, t=1.89, p(MCMC)=0.06). Main effects Context At Region 1, the first clause of the causal relation, we observed main effects of context. This region was processed slower in subjective compared to neutral contexts. This effect appeared in first pass reading times (ß=0.182, SE=0.026, t=7.08, p(MCMC)<0.001), right-bounded time (ß=0.225, SE=0.016, t=14.36, p(MCMC)<0.001), regression path duration (ß=0.228, SE=0.017, t=13.52, p(MCMC)<0.001) and total time (ß=0.228, SE=0.018, t=12.88, p(MCMC)<0.001).Note, that we manipulated the presence of evaluative markers in this region, which therefore contains more words in subjective compared to neutral contexts. As a result, the main effects of context at this position are difficult to interpret. The same effects surfaced at Region 3, the words following the connective in right-bounded time (ß=0.051, SE=0.022, t=2.29, p(MCMC)<0.05), regression path duration (ß=0.061, SE=0.025, t=2.43, p(MCMC)<0.02) and total time (ß=0.067, SE=0.027, t=2.52, p(MCMC)<0.05). And at Region 6, the final sentence of the text in regression path duration (ß=0.034, SE=0.017, t=1.95, p(MCMC)<0.05 (one–tailed)).

It is not enough to know that the author is giving his personal opinion to overcome the processing difficulty associated with claims as marked by want. These results suggest that readers need more specific cues to derive the status of S1 as a claim. The purpose of Experiment 2 was to verify how specific these cues need to be. We know that explicit signals, such as John thinks and perhaps, that modify the status of S1 as a whole, cancel out the processing difficulty for subjective compared to objective causal relations. In Experiment 2 we tested whether this can also be achieved by non-sentence modifying markers of subjectivity within S1. We therefore manipulated evaluative adverbs and adjectives such as ridiculously, fantastic, and horrible in the first clause of the causal relation. As illustrated in (16) here repeated in (19), these markers convey the author’s emotional involvement, yet they do not modify the entire sentence. If used as in (19) they only modify a subpart of S1. (19) Het huidige niveau van de studenten is [belachelijk [laag]] The students' current skill level is [ridiculously [low]] We hypothesized that if language users can derive the status of a sentence as a claim by the presence of these markers within that sentence, the disadvantage in processing time for want over omdat should be canceled out. If, however, this status can only be derived by linguistic devices that have the ability to modify the entire sentence as a claim, we expect that the presence of evaluative markers within S1 will not affect the processing asymmetry between want and omdat. The results replicate the findings of Experiment 1. We observed longer processing times for want compared to omdat at the words immediately following the connectives in both subjective and neutral contexts. Again, there was no sign of an interaction at this point in the sentence. The manipulation of evaluative markers in the first clause of the causal relation had no influence on the processing of want and omdat. These results suggest that readers cannot derive the status of S1 as a claim by the presence of the author’s evaluation within that sentence. Rather, this information needs to be explicitly cued by markers that modify S1 as a whole, such as modal sentence adverbs (perhaps) and mental state predicates (John thinks). Similar to the results of Experiment 1, Experiment 2 produced main effects of Context. Evaluative adverbs and adjectives in the context and the first clause of the causal relation led to longer processing times of the words 88|Chapter 4 following the connective region and the final sentence of the text. In the general discussion we will discuss these effects in more detail. There was no indication of a context-by-relation match/mismatch effect during end of sentence processing. The final region of want and omdat relations was not processed differently in subjective compared to neutral contexts. This indicates that the interaction effect observed in Experiment 1 cannot be interpreted as a reflection of the match between Context and the type of relation. We therefore conclude that this effect must have been caused by differences between the conditions with respect to the segmentation of the sentences and their distribution of information. 4.5 General Discussion The purpose of the present study was to further investigate the relative processing difficulty associated with CLAIM-ARGUMENT relations, as reported for English (Traxler, Bybee, & Pickering, 1997) and Dutch (Chapter 3) On the basis of previous research, we argued that this effect is related to the representation of the first clause of a CLAIM-ARGUMENT relation as a claim or conclusion, as opposed to a real-world description of causes and effects in an objective causal relation. In order to get a better understanding of the cognitive processes involved, we investigated how language users recognize the special status of sentences as claims. In Experiment 1, we assessed whether this representation could be derived from contextual cues of speaker involvement, or mental space builders. Mental Spaces Theory (MST) (Fauconnier, 1994) is a cognitive linguistic framework that has been used to describe a variety of linguistic phenomena, among which the distinction between subjective and objective causal relations (Sanders, Sanders, & Sweetser, 2009, 2012; Verhagen, 2005). According to this framework, language users build, and constantly update, a network of mental spaces when they communicate. These mental spaces are conceived as conceptual spaces in which information bound to time, space, and person is represented relative to the here and now. Within MST it is assumed that certain linguistic signals, such as connectives, function as space builders. Relevant to our discussion here is that mental space configurations can differ in their overall complexity. In fact, Sanders, Sanders and Sweetser (2009, 2012), argue that the mental space configuration of a subjective causal relation is more complex than the configuration of an objective relation because the latter involves conclusions within the mental space of a thinking subject, be it the speaker, author, or a character in the discourse whose reasoning is presented. Even though MST was not developed as a processing theory, we applied these insights to the processing effects associated with subjective causal relations. We hypothesized that these effects could be related to the construction of the relevant mental space for interpretation. If this operation Contextual versus linguistic signals of speaker involvement|89 underlies the processing difficulty for claims as marked by want, we hypothesized that this difficulty should be canceled out if the context preceding the causal relation contains space builders that already provide the required mental space for interpretation. We set out to verify this hypothesis by testing CLAIM-ARGUMENT relations with want and CONSEQUENCE-CAUSE relations with omdat in contexts with and without contextual cues of speaker involvement. Speaker involvement was manipulated by means of evaluative adverbs and adjectives, such as terribly, fantastic and ridiculous, in the context preceding the causal relations. These markers express the author’s emotional stance towards the matter under discussion (Thompson & Hunston, 2000) and therefore function as cues to the reader that the text is to be interpreted from the author’s perspective. The eye-tracking data from Experiment 1 revealed that this information has no influence on the processing of want. In line with the results presented in Chapter 3, we observed an immediate disadvantage in processing time for want compared to omdat in both subjective and neutral texts. This effect surfaced at the connective and the first text region following the connective. These results suggest that it is not enough to know that someone is giving his personal opinion to overcome the processing difficulty associated with CLAIM-ARGUMENT relations. Therefore, it seems that the processing asymmetry between subjective and objective causal relations cannot be explained in terms of the construction of additional mental spaces. Note, that these results cannot be explained by the fact that implicit reference to the author by means of evaluative markers is too implicit to trigger the construction of the author’s mental space. Previous experiments demonstrated that explicit third person perspective markers, such as John thinks or According to John, cancel out the processing difficulty in the second clause of subjective causal relations. However, Traxler, Sanford, Aked, and Moxey (1997) also report the same effect for epistemic modal adverbs, such as probably and maybe, which also implicitly refer to the speaker or author. These results show that explicit reference to a third person concluder is not a prerequisite to cancel out the processing difficulty of subjective causal relations. A limitation to the application of MST as a theory for online discourse processing is that within MST the relative complexity of mental spaces configurations concerns their overall configuration; it lacks a specification of the cognitive processes underlying the incremental construction of these configurations. Or, simply put, it doesn’t specify when it gets difficult and why. As a working hypothesis, we proposed that the complexity of subjective causal relations is related to the construction of the relevant mental space for interpretation. We hypothesized that once a mental space is called into existence, it can be used freely for the interpretation of linguistic input. Our 90|Chapter 4 data suggest that this is not the case. Mental space builders in the context preceding a want relation do not cancel out the processing asymmetry between want and omdat. However, on the basis of MST it remains unclear whether the relative complexity of a specific configuration should be described in terms of the setup of the different mental spaces, the maintenance of different spaces, or to the fact that certain utterances need to be mapped onto certain spaces. It may in fact be the case that it is not the construction of mental spaces that leads to the processing effects associated with subjective causal relations, but the mapping of information onto the mental space of the thinking subject. Even if the author’s perspective is clearly “visible” in a given discourse, it would not make sense to interpret everything he or she utters as a claim or conclusion because argumentative text can also contain objective descriptions of the world. Nevertheless, the activation of a mental space may lead to a more careful evaluation of how to interpret the following utterances in a discourse, that is, as claims or not. Indeed, the results from the Experiments presented in this chapter reveal that the presence of mental space builders in the context leads to different reading strategies. In both experiments, the presence of evaluative markers in the contexts led to longer processing times of subsequent text regions compared to neutral contexts. In Experiment 1 this effect surfaced at the first part of S1 and at the final sentence of the text. Similar effects surfaced in Experiment 2. Recall that these regions contain exactly the same information in subjective and neutral contexts, which means that these effects can only be caused by the presence of evaluative markers in the preceding text. These results illustrate that readers take more time to interpret information that is preceded by markers of subjectivity. If we take higher order processes into account, one could argue that these context effects are related to genre expectations. Such expectations are assumed to guide the cognitive activities involved in text comprehension processes as well as the ways in which readers represent discourse information in memory (see Zwaan & Rapp, 2006 for an overview; Steen, 2011; Zwaan, 1994). These expectations are set by experience, text specific tasks and goals, but could also be cued by implicit information such as the evaluative markers in our texts. These markers may have affected the overall processing strategies because the presence of the author’s perspective is unexpected in the news genre. However appealing this explanation might be, it does not provide a straightforward explanation for our results. First, it is unclear why a shift in genre expectations should lead to an increase in processing times that surfaces later on in the text. Second, the presence of evaluative markers is not uncommon in certain types of newspapers. As such, an explanation for the context effects obtained in the experiments 1 and 2 may not be the most plausible explanation. Contextual versus linguistic signals of speaker involvement|91 Returning to the central question of this chapter, how do readers know when a given utterance is to be interpreted as a claim and mapped onto a specific mental space? We proposed that the connective want functions as a signal to place S1 within the mental space of the thinking subject. On the basis of the results from Experiment 1 we argued that readers need relatively specific cues about the status of a sentence as a claim to do so. Experiment 2 provides further information about how specific these cues need to be. Previous experiments in Dutch (Chapter 3) and English (Traxler, Sanford, Aked, & Moxey, 1997) revealed that the disadvantage in processing time for subjective compared to objective causal relations is canceled out if the first clause of the relation contains mental state predicates, such as according to John, or modal sentence adverbs, such as perhaps. These markers can be conceived as local markers of subjectivity because they inform the reader about the perspective from which the utterance is produced. In addition, they modify the entire sentence as a claim that belongs to the person whose reasoning is presented. In Experiment 2 we verified which of these properties is related to the processing of claims by testing whether the processing difficulty for subjective over objective causal relations can be overcome by non-sentence modifying markers of subjectivity within S1. In a design similar to Experiment 1, we manipulated evaluative adjectives and non-sentence modifying adverbs within the first clause of the relations, such as ridiculously in (15) and (19), here repeated in (20). These markers provide the author’s opinion about the states of affairs and therefore add an argumentative flavor to the sentence. However, as example (20) illustrates, these markers do not modify the sentence as a whole but only a subpart. (20) Het huidige niveau van de studenten is [belachelijk [laag]] The students' current skill level is [ridiculously [low]] The results from Experiment 2 reveal that the presence of these markers does not facilitate the processing of subjective causal relations. As in Experiment 1, we observed an immediate disadvantage in processing time for want over omdat in relations with and without local markers of subjectivity. Making the first clause of a causal relation argumentative does not contribute to the representation of S1 as a claim. On the basis of these results we propose that want modifies the status of S1 as a whole as a claim or conclusion. Unlike the evaluative adjectives and non-sentence adverbs manipulated in the present study, mental state predicates such as according to John and modal sentence adverbs such as perhaps have scope over the entire sentence. They therefore cue the representation of claims before the connective is processed, which explains why they cancel out the disadvantage in processing times for subjective 92|Chapter 4 causal relations. In terms of our MST explanation, these phrases already cue the mapping of S1 onto the mental space of the thinking subject, and this operation is already performed when encountering want. What these markers share with the evaluative markers in the present study is that they modify pieces of information as relying on a specific discourse referent for their interpretation. The results from the present study suggest that the level at which they operate is crucial for the processing of subjective causal relations. For example, the evaluative adverb ridiculously in (20) provides a subjective evaluation of the adjective low. Therefore, only a subpart of the sentence, the evaluation of the adjective, is clearly marked as subjective. The truthfulness of the rest of the sentence is not at stake. Conversely, modal sentence adverbs such as waarschijnlijk, (probably) in (21) do affect the status of the entire sentence. What is at stake is the truthfulness of the entire clause following waarschijnlijk. This distinction is reminiscent of the distinction between ‘shields’ and ‘approximators’ proposed by Prince, Frader, and Bosk (1982). The former are conceived as local markers of the speaker’s evaluation whereas the latter are described as global markers that modify the status of entire propositions. (21) Waarschijnlijk [is het huidige niveau van de studenten laag] Probably [the students' current skill level is low] One could question whether there are other (contextual) manipulations of subjectivity that could facilitate the mapping of S1 onto the mental space of the thinking subject, which would reduce the effects of want versus omdat. We chose to use markers of evaluation because this allowed us to minimally alter the neutral contexts, which is desirable when you monitor and compare eye-movements across conditions. Yet, there may be different (and possibly stronger) ways to provide the relevant perspective that could prepare the reader for a CLAIM-ARGUMENT relation. Examples (1)–(3) at the beginning of this chapter suggest that the communicative context can cue the required interpretation. Future research will have to establish whether such information does eliminate the processing difficulty of subjective compared to objective causal relations. Nevertheless, the data presented in this chapter indicate that manipulating evaluative adverbs and adjectives is an effective way to provide the perspective of the thinking subject. The offline judgment tasks presented in both Experiments 1 and 2 show that readers are sensitive to this manipulation. Subjective contexts received higher scores on persuasive intent compared to neutral texts. Moreover, the online data revealed that this information also influences online processing. Taken together, our results reveal that signals of evaluation, either in the context preceding a want relation or within S1 of a want relation, do not facilitate the construction of a CLAIM-ARGUMENT relation. These markers Contextual versus linguistic signals of speaker involvement|93 indicate that the text is to be interpreted from the author’s point of view, but apparently, want signals something else. Our results suggest that the cognitive processes underlying the processing difficulty of subjective compared to objective causal relations, as marked by want and omdat, is related to a modification of S1 as a whole as a conclusion or claim. Subjective relations, marked by want, require an interpretation of the entire first clause within the mental space of the thinking subject. Even in the presence of the relevant perspective in the context and in the first clause of the relation, this operation still has to be executed at encountering want. There are, however, different ways to explain why this operation should cause processing difficulties in CLAIM-ARGUMENT relations. So far, it is unclear whether this effect is caused by the fact that the information in S1 needs to be reanalyzed as a claim or conclusion (or copied from one mental space to the other), or whether this is the result of inherently complex operations. Traxler, Sanford, Aked, and Moxey (1997) propose that the processing difficulty observed in diagnostic causal relations is caused by the fact that it has not been made clear that the first clause of the relation is a psychological event. They argue that the default interpretation of the first clause of a causal relation is an objective interpretation of the state of affairs in the world. Therefore the processing effects associated with diagnostic causal relations surface because “the text does not signal that a less preferred [subjective] interpretation should be adopted” (p. 89). Traxler, Sanford, Aked, and Moxey thus treat these effects along the lines of the garden path effects associated with reduced relatives and reduced complements (Ferreira & Henderson, 1990; Trueswell, Tanenhaus, & Garnsey, 1994; Trueswell, Tanenhaus, & Kello, 1993). A straightforward way to verify this explanation is by looking at forward causal relations. In Dutch, a similar distinction between subjective and objective connectives exists in the forward causal connectives dus and daarom. Similar to want, dus is considered to be a subjective connective whereas daarom is considered to be a more objective connective (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, Sanders & Verhagen, 2009; Verhagen, 2005). However, in forward subjective relations there can be no reanalysis of the conclusion triggered by the connective because the conclusion follows the connective. If dus and daarom lead to a similar processing asymmetry as want versus omdat, this would support the idea that subjective relations are inherently more complex than objective relations. This inherent complexity of subjective causal relations could be related to the fact that claims and conclusions convey information that is not necessarily true. In fact, the reason why people provide arguments to support claims is to convince their interlocutors of the truth of those claims. Overt marking of the status of information as a claim may therefore lead to a 94|Chapter 4 more careful evaluation of those claims, or epistemic vigilance (Sperber et al., 2010). Epistemic vigilance is assumed to be a cognitive mechanism involved in the assessment of truthfulness of information and is associated with a processing cost. With respect to coherence marking, it has already been proposed that subjective coherence markers trigger similar processes as becomes apparent in measures of persuasion (Kamalski, Lentz, Sanders, & Zwaan, 2008). Further research will have to establish whether the processing effects reported in this chapter can be related to these mechanisms. Chapter 5 On the processing complexity of subjective causal relations: From reasoning to speaker involvement 5.1 Introduction The distinction between subjective and objective causal relations, which surfaces in many languages of the world, has been well studied from a textlinguistic and discourse theoretical perspective. The majority of these studies focus on the exact classification of the different relations, and on the question of whether or not the distinction is also represented in the lexicon of coherence markers (as discussed in Chapter 2). On the basis of psycholinguistic insights, subjective causal relations are claimed to be more complex than objective causal relations (Chapter 2-3; Noordman & De Blijzer, 2000; Sanders & Spooren, 2009). Indeed, corpora of Dutch and English child language data show that subjective causal relations appear later than objective causals (Evers-Vermeul & Sanders, 2011; Spooren & Sanders, 2008), and there are some processing studies that also point into that direction. Eye-tracking studies by Traxler, Bybee, and Pickering (1997) revealed that subjective causal relations such as (1b) lead to longer processing times compared to objective causal relations (1a). (1) a. The goalkeeper won the game because the other team didn’t score any goals. b. The goalkeeper knew how to play the game because the other team didn’t score any goals. The eye-tracking experiments presented in Chapters 3 and 4 also revealed a processing slowdown in Dutch subjective compared to objective causal relations. In these experiments, the subjective relations are marked by the prototypically subjective connective want, whereas the objective relations are marked by the prototypically objective connective omdat. An important difference between English and Dutch is that the Dutch causal connectives want and omdat provide cues for the construction of subjective and objective relations respectively, whereas because is underspecified in this respect. As reported in Chapter 3, the effects in Dutch arise immediately after the subjective connective want is processed, whereas the English effect surfaces later on in the sentence when the relation can be inferred from the content. Interestingly, the effects in both languages are canceled out when the first clause of the causal relation is preceded by mental state predicates (according to John or John thinks) (Chapter 3; Traxler, Sanford, Aked, & 96|Chapter 5 Moxey, 1997) or modal sentence adverbs (maybe, possibly) (Traxler, Sanford, Aked, & Moxey, 1997). Thus, explicitly marking the status of S1 as a claim eliminates the longer processing times in subjective CLAIM-ARGUMENT compared to objective CONSEQUENCE-CAUSE relations. The experiments presented in Chapter 4 revealed that this canceling out effect cannot be achieved by evaluative adverbs and adjectives (ridiculously, terrible, luckily), which introduce the author’s perspective, placed in the context preceding the causal relation and within the first clause of the relation (2). (2) Pabo moet echt beter! De Nederlandse Pabo-opleidingen gaan vanaf volgend jaar eindelijk meer aandacht besteden aan het niveau van de studenten. In plaats van 8 uur wordt er dan maar liefst 14 uur per week uitgetrokken voor reken- en taalvakken. Teachers Training Colleges must improve! Starting next year, the Dutch Teacher Training colleges will finally pay more attention to their students’ maths and language skills. They will increase the number of teaching hours dedicated to maths and languages from as many as 8 to 14 hours a week. a. Het huidige niveau van de studenten is belachelijk laag want slechts de helft haalt een voldoende voor rekenen en taal. The students' current skill level is ridiculously low want only half of them pass the maths and language tests. b. Het huidige niveau van de studenten is belachelijk laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. The students' current skill level is ridiculously low omdat only half of the teaching hours are dedicated to maths and language. These results suggest that markers of subjectivity that only modify a subpart of S1, rather than S1 as a whole, do not have the same effect on the processing of want as mental state predicates (volgens Jan) and modal sentence adverbs (possibly) do. This led to the conclusion that the processing delay in reading times for want, and for subjective relations in general, has to be related to a modification of the asserted information in S1 as a whole as a claim or conclusion. Hence, in Chapter 4, we proposed that want adds information that modifies the status of the entire clause preceding the connective as a conclusion or claim. There are at least two explanations for why the processing of conclusions could be a complex operation. First, given that conclusions are products of reasoning, it may be the case that the cognitive complexity associated with subjective causality is related to this underlying process. Reasoning can be defined as a “simulation of the world fleshed out with our knowledge” (Johnson-Laird, 2010, p.1). It involves the construction of a set of possible mental models compatible with The processing complexity of subjective causal relations|97 a given situation in the world, on the basis of which a conclusion is derived. It may therefore be the case that subjective causal relations invite the reader, or listener, to follow the underlying steps of reasoning, which increases the processing load. Second, conclusions as part of subjective relations entail speaker involvement (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003). These relations involve a thinking subject who takes responsibility for the conclusion; it therefore needs to be interpreted within the mental world of that thinking subject (as proposed in Chapter 4). As discussed in Chapter 2, the thinking subject can be the speaker, author, or a character in the discourse whose reasoning is presented. In our discussions of subjectivity and speaker involvement we will by default refer to this thinking subject as ‘the speaker’, unless it is of particular relevance to specify the exact thinking subject whose reasoning we are dealing with. It could be that the operation of assigning information to the mental world of the speaker is in itself demanding. Also, the fact that the representations of different realities (the real world versus the speaker’s mental world) have to be maintained simultaneously could increase the cognitive load. In addition, it may be the case that because the conclusion is linked to the internal world of the speaker, the reliability of that conclusion is at stake depending on the reliability of the speaker. For example, the claim in (3) is more credible when it is produced by the weatherman than by an umbrella salesman. (3) I think it will rain today. Therefore, information bound to specific mental spaces may require a more careful evaluation on behalf of the reader, or listener. This hypothesis is compatible with the results from Experiment 1 in Chapter 4. We observed that want relations increase the processing times of the sentence following the relation, which was interpreted in terms of more careful evaluation. However, given that the studies described above involve backward relations1, subjective CLAIM-ARGUMENT versus objective CONSEQUENCE-CAUSE, it is unclear whether the longer processing times for subjective compared to objective causal relations arise because subjective relations are inherently more complex, or because the reader has to reanalyze the information in S1 as a claim or conclusion rather than a description of the world. This explanation is put forward in Traxler, Sanford, Aked, and Moxey (1997) who propose that the processing difficulty observed in English Noordman and De Blijzer (2000) did include forward subjective relations in their study. However, various factors were manipulated at the same time, which makes it difficult to draw conclusions about individual factors. 1 98|Chapter 5 subjective compared to objective causal relations is caused by the fact that it has not been made clear that the first clause is a psychological event. They argue that the default interpretation of the first clause of a causal relation is an objective interpretation of the state of affairs in the world. Therefore, the processing effects associated with subjective causal relations surface because “the text does not signal that a less preferred [subjective] interpretation should be adopted” (p.89). Traxler, Sanford, Aked, and Moxey thus treat these effects along the lines of the garden path effects associated with reduced relatives and reduced complements (Ferreira & Henderson, 1990; Trueswell, Tanenhaus, & Garnsey, 1994; Trueswell, Tanenhaus, & Kello, 1993). A straightforward way to verify this explanation is by investigating how forward subjective connectives affect the processing of causal relations. From a cognitive perspective, forward and backward causal relations are assumed to be shaped by the same conceptual notions (Sanders, Sanders, & Sweetser, 2012) that do not change when the order of presentation is changed. In backward subjective relations (4a) the claim precedes the argument, whereas in forward subjective relations (4b) the argument precedes the claim or conclusion. (4) a. Lisa heeft te veel geshopt deze maand want ze kan niet meer pinnen. Lisa has been shopping too much this month because her bank account is empty. b. Lisa kan niet meer pinnen dus heeft ze te veel geshopt deze maand. Lisa’s bank account is empty so she has been shopping too much this month. In (4b), dus signals that the following clause is to be interpreted as a conclusion. Therefore, in this type of subjective relations there can be no reanalysis of the already processed information as a claim because the claim follows the connective dus. 5.2 Dus and daarom versus want and omdat Similarly to the distinction between want and omdat, speakers of Dutch distinguish between the connectives dus and daarom to express forward subjective and objective causal relations (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, 2005; Verhagen, 2005) (see Table 1.). Similar to omdat, daarom is a prototypical marker of objective CAUSECONSEQUENCE relations such as (5a). The fact that Peter has not eaten anything all day leads to the situation (or his action) that he orders a pizza. Comparable to want, dus is generally described as a subjective connective that marks subjective ARGUMENT-CLAIM relations such as (5b). The fact that Peter filled his plate for the second time leads to the speaker’s conclusion that he must have been very hungry. The processing complexity of subjective causal relations|99 Table 1. Summary of the differences between the Dutch causal connectives daarom versus dus and omdat versus want. P and Q stand for antecedent and consequent respectively. S1 corresponds to the first discourse segment and S2 corresponds to the second discourse segment. Volitional Objective Subjective Direction Daarom (that’s why) Dus (so) Forward: S1=P, S2=Q Omdat (because) Want (because/since) Backward: S1=Q, S2=P (5) a. Peter had de hele dag niks gegeten, daarom bestelde hij een pizza. Peter hadn’t eaten anything all day, that’s why he ordered a pizza. b. Peter schepte voor de tweede keer op, dus had hij veel honger2. Peter filled his plate for the second time, so he was very hungry. The connectives daarom and dus are highly frequent in Dutch. Their log frequency based on the Celex corpus of written Dutch (Baayen, Piepenbrock, & Gulikers, 1995) is 4.1 and 4.5 (per million words) respectively. While want and dus are considered to have similar semantic-pragmatic properties (Sanders, Sanders, & Sweetser, 2009, 2012; Verhagen, 2005), they differ with respect to the direction in which they operate (Sanders, Spooren, & Noordman, 1992). In CLAIM-ARGUMENT relations marked by want, the clause preceding the connective contains the asserted information, which is justified by the information in the second clause (6a). In ARGUMENTCLAIM relations marked by dus, the asserted information is presented in the clause following the connective, which consists of a conclusion based on the premise in the first clause (6b). 2 In the experiments described in this study we used dus in its adverbial position in the syntactic structure, as in (a), in which it triggers the inversion of the finite verb, because this allowed us to compare dus and daarom with the same word order. When dus functions as a complementizer, as in (b), this inversion does not apply. 1. 2. Peter schepte voor de tweede keer op, dus had hij veel honger. [Peter filled his plate for the second time, so had he a lot of hunger.] Peter filled his plate for the second time, so he was very hungry. Peter schepte voor de tweede keer op, dus hij had veel honger. [Peter filled his plate for the second time, so he had a lot of hunger.] Peter filled his plate for the second time, so he was very hungry. Even though dus allows for these two different forms, this difference has no effect on the type of relation marked by this connective (Evers-Vermeul, 2005; 2010). Although Verhagen (2005, p.199) suggests that there may be a difference in the relative degree of subjectivity between these two versions, both versions are considered to be subjective. 100|Chapter 5 (6) a. Peter had veel honger, want hij schepte voor de tweede keer op. Peter was very hungry, because he filled his plate for the second time. b. Peter schepte voor de tweede keer op, dus had hij veel honger. Peter filled his plate for the second time, so he was very hungry. Similarly, in CONSEQUENCE-CAUSE relations marked by omdat (7a), the clause preceding the connective conveys the consequence of the situation described in the second clause. This order is reversed in CAUSECONSEQUENCE relations marked by daarom (7b). (7) a. Peter schepte voor de tweede keer op, omdat hij veel honger had. Peter filled his plate for the second time, because he was very hungry. b. Peter had veel honger, daarom schepte hij voor de tweede keer op. Peter was very hungry, that’s why he filled his plate for the second time. Example (6) illustrates that similar processes are induced by dus and want, yet want modifies the status of S1 whereas dus modifies S2. This means that in forward subjective relations there can be no reanalysis of the conclusion triggered by the connective, because the conclusion follows the connective. If the delay in processing times for CLAIM-ARGUMENT relations marked by want is related to a reanalysis of S1 as a claim, forward subjective relations, as marked by dus, should not cause processing difficulties compared to objective relations marked by daarom. If, on the other hand, subjective relations are inherently more complex than objective relations, we should observe a similar processing asymmetry between dus and daarom as has been reported for want versus omdat. 5.3 Experiment 1 5.3.1 Participants Forty undergraduate students from Utrecht University participated in the experiment (20 female, mean age 23.7 age range 18–45 years). All participants were native speakers of Dutch and were paid for their participation. 5.3.2 Materials and design The materials consisted of 20 sets of forward causal relations marked by either dus (8a) or daarom (8b) (see Appendix 4 for more examples). (8) a. Tim heeft morgen een tentamen. Dus zit hij al uren te studeren. Tim has a test tomorrow. So he has been studying for hours. b. Tim heeft morgen een tentamen. Daarom zit hij al uren te studeren. Tim has a test tomorrow. That’s why he has been studying for hours. The processing complexity of subjective causal relations|101 80 Filler items were added to the materials. These filler items consisted of the 40 sets of items that are reported in Experiment 2, and 40 unrelated sentence pairs. The sentences were divided over two lists according to a Latin square design, so that each list contained only one version of an item. The items were presented in four blocks of stimuli. Line breaks were placed before the word preceding the connective. We did this to make sure that the regions of interest were not situated at the beginning or end of a line. Verification statements were randomly divided over the stimuli and appeared after 25% of the items. Participants were informed to respond to these statements by pressing the ‘yes’ or ‘no’ button on the button box. 5.3.3 Apparatus and procedure Eye movements were recorded with a desktop-mounted EyeLink 1000 eyetracker, which samples the right eye at 500Hz. The system has an eye position tracking range of 32 degrees horizontally and 25 degrees vertically, with a gaze position accuracy of 0.5 degrees. The materials were presented on a 19-inch computer screen at a viewing distance of approximately 60 centimeters. All participants were individually tested in a testing booth at the University. Before the experiment started, participants were informed about the procedure and the experimenter made sure that they were comfortably seated. Participants were asked not to move their heads or blink excessively during the experiment. Each experiment started with a thirteenpoint calibration procedure followed by a validation procedure, which was repeated before each block. The experiment started with a practice trial of 5 items. 5.3.4 Results The critical sentence, starting with the connectives dus or daarom, was divided into 4 regions for analysis, see example (9). Region 1 contains the connective. Region 2 consists of the two subsequent words, in most cases an auxiliary and the subject. Region 4 comprises the final words of the sentence and contains the key information to construct the causal relation. And Region 3 consists of all the words in between regions 2 and 4. (9) | Dus / Daarom 1| zit hij 2 | al uren 3| te studeren 4 | | So / that’s why 1| sits he 2 | for hours 3| to study 4 | Correct answers to the verification statements were given in 93% of the trials. Blinks were extracted from the data. All observations that were two standard deviations above or below item and subject mean for each position and condition were excluded from the analysis. Following these criteria we removed 1.1% of the data (162 cases). We analyzed the following measures: first pass reading times, right-bounded time, regression path duration, and 102|Chapter 5 total reading time. First pass reading times is what Rayner and Duffy (1986) call gaze duration for single words, and consists of all fixations within a region (including saccades) before moving into a forward or a backward direction. Right-bounded time (or total gaze duration) sums all fixations within a region before moving on progressively. This measure consists of first pass reading times, including fixations that follow regressions. Regression path duration (Konieczny, Hemforth, Scheepers, & Strube, 1997) consists of all fixations on a region before passing on in a forward direction, including rereading of previous material. Total reading time is the Total time spent at a region. This measure includes the time required for reanalysis when a piece of information is not completely processed during the first reading (Rayner & Sereno, 1994). Means are reported in Table 2.

Eye-movement data typically have a lot of missing values, especially if the regions of interest are short. However, multilevel analyses such as LMER are robust against missing data (Quené & van den Bergh, 2004). These analyses were performed on the log-transformed data in order to meet the normality requirements of linear modeling. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). The results at Region 1, containing either dus or daarom, will not be discussed because the length difference between these two connectives makes any effects difficult to interpret. The processing complexity of subjective causal relations|103 We observed longer processing times for dus compared to daarom at Region 2, the words following the connective. This effect surfaced in first pass reading times (ß=0.164, SE=0.029, t=5.65, p(MCMC)<0.001), rightbounded time (ß=0.168, SE=0.030, t=5.64, p(MCMC)<0.001), regression path duration (ß=0.174, SE=0.032, t=5.50, p(MCMC)<0.001) and total time (ß=0.198, SE=0.037, t=5.36, p(MCMC)<0.001). No significant effects were observed in any of the other regions. 5.3.5 Discussion Experiment 1 reveals that dus leads to longer processing times of the immediately following text region compared to daarom. These results suggest that the forward connectives dus and daarom produce a similar processing pattern as the backward connectives want and omdat, reported in Chapters 3 and 4. Therefore, the longer processing times for subjective compared to objective relations reported in previous studies (Chapter 3-4; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997) cannot be explained in terms of a reanalysis of the already processed information as a claim or conclusion, as proposed by Traxler, Sanford, Aked, and Moxey (1997). Instead, we propose that the cognitive operations involved in the representation of subjective causal relations are inherently complex. Under this assumption, it is to be expected that processing effects surface at the moment at which the representation of the subjective relation is constructed. Therefore, linguistic devices that trigger this subjective representation, such as dus and want, are expected to immediately induce longer processing times compared to markers that do not, such as omdat and daarom. We argue that daarom provides immediate processing instructions that lead to the construction of a volitional CAUSE-CONSEQUENCE relation. If this is the case, it is expected that daarom causes processing difficulties when the content of the text segments is not compatible with this interpretation. Take, for example, the ARGUMENT-CLAIM relation with dus in (10a): the fact that Peter ordered two pizzas leads to the speaker’s conclusion that he must have been hungry. (10) a. Peter bestelde 2 pizza’s, dus had hij grote honger. Peter ordered 2 pizzas, so he was very hungry. b. #Peter bestelde 2 pizza’s, daarom had hij grote honger. #Peter ordered 2 pizzas, that’s why he was very hungry. If daarom is used to mark the same relation (10b), the interpretation changes into an objective CAUSE-CONSEQUENCE relation: the fact that Peter ordered two pizzas leads to the situation that he is hungry, an interpretation that makes no sense (Sanders, Sanders, & Sweetser 2009, 104|Chapter 5 p.38). If the connective daarom triggers the immediate construction of a CAUSE-CONSEQUENCE interpretation while dus triggers an ARGUMENT-CLAIM relation, we expect an initial processing facilitation for daarom compared to dus in relations such as (10), as surfaced in Experiment 1. However, at the end of the second clause, at which point readers have al the necessary information to construct the causal relation, it is expected that they will experience difficulties interpreting the relation marked by daarom because it makes no sense. We therefore expect to find longer processing times at the end of relations such as (10) with daarom compared to dus. Assuming that the processing difference between dus and daarom is a reflection of the difference between subjective and objective causal relations, the next question is: how do we explain these effects? Experiment 1 demonstrates that the delay in processing times for subjective causal relations cannot be explained in terms of a reanalysis of already processed information. Instead, the data suggest that subjective relations are inherently more complex than objective causal relations. In what follows we will further investigate the cognitive mechanisms underlying this complexity. In line with earlier results (Chapter 3-4; Traxler, Sanford, Aked, & Moxey, 1997), we propose that subjective causal connectives trigger the representation of one of the two text segments as a conclusion, or claim, based on the premise in the clause with which it is connected. In the introduction of this chapter we proposed that the representation of conclusions could be resource demanding because conclusions rely on reasoning. Alternatively, this effect may be related to the fact that a thinking subject is responsible for the presented conclusion. In what follows we will systematically investigate which of these approaches adequately explains the processing complexity of subjective causal relations. If this complexity is explained by the fact that subjective relations involve reasoning, other linguistic devices that also mark reasoning should lead to similar effects. In Dutch, there are no other forward causal connectives that share this property with dus. There are, however, adverbs with similar semantic– pragmatic characteristics, such as the inferential evidential adverb blijkbaar, which can be translated by evidently. The function of evidentials is to mark the source of information underlying statements. These sources can be direct or non-direct, first-hand or second hand, based on hearsay or reasoning. Blijkbaar belongs to the class of indirect evidentials because it is used when the speaker has not witnessed an action himself, but has deduced it on the basis of indirect perceptible evidence (11a). (11) a. Mies heeft haar pasta niet opgegeten, blijkbaar had ze geen honger. Mies did not finish her pasta, blijkbaar she wasn’t hungry. b. Mies heeft haar pasta niet opgegeten, dus had ze geen honger. Mies did not finish her pasta, dus she wasn’t hungry. The processing complexity of subjective causal relations|105 As an inferential evidential, blijkbaar identifies evidence based upon reasoning (Van der Auwera & Plungian, 1998). As such, dus and blijkbaar share the property that they mark conclusions as derived by reasoning, which modifies the status of S2 as a whole as a conclusion. Therefore, the relation expressed by blijkbaar in (11a) seems comparable to the relation in (11b) expressed by dus. Unlike dus, evidentials such as blijkbaar signal that the evidence underlying the conclusion is outside the speaker’s belief (Giannakidou, 2011; Nuyts, 2001). By using blijkbaar the speaker signals that he or she does not take responsibility for the conclusion. Note, that even though blijkbaar and dus can be used in the same relation with the same evidence presented in S1, these markers emphasize different levels of speaker involvement in the conclusions. If the processing difficulty of subjective causal relations is explained by the fact that they involve reasoning, irrespective of the degree of speaker involvement, blijkbaar should also lead to longer processing times compared to daarom. Yet, no processing differences are expected between dus and blijkbaar. If, on the other hand, the relative involvement of the speaker’s mind is responsible for the processing difference between dus and daarom, we expect to obtain longer processing times for dus compared to daarom and blijkbaar. An additional question addressed in this study concerns the integration effect associated with causal connectives. It is generally assumed that causal connectives contribute to the construction of causal relations. As discussed in Chapter 2, a general finding in experimental studies is that the presence of a causal connective, or cue phrase, speeds up the processing of the first words of the second clause, compared to an implicit version of the same relation (e.g. Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Millis & Just, 1994; Sanders & Noordman, 2000). However, if dus increases the processing load because it signals the construction of a subjective relation, this connective may not lead to such a speeding up effect. Results from previous experiments in Dutch suggest that is may indeed be the case. The use of dus has been shown to lead to no processing difference (De Leeuw, Mak, & Sanders, 2008), and even longer processing times (Kleijn, Mak, & Sanders, 2011), compared to implicit relations. In order to investigate the effects of the different markers on the integration of the two clauses, we added an implicit condition to our design. 5.4 Experiment 2 5.4.1 Participants Because Experiments 1 and 2 were run as one experiment, see Experiment 1 for participant details. 106|Chapter 5 5.4.2 Materials and design We created 40 ARGUMENT-CLAIM relations in which we varied coherence marking in 4 conditions: dus (12a), daarom (12b), blijkbaar (12c) and implicit (12d) (see Appendix 4 for more examples). All items are based on strong CAUSE-CONSEQUENCE relations, which we inverted to arrive at plausible ARGUMENT-CLAIM relations. For example, walking in the rain usually leads to getting your hair wet. Inverting this reasoning results in the relation in (12a). “Petra’s hair is wet, so it must be the case that it has been raining outside”. This interpretation is unproblematic with blijkbaar (12c). However, the use of daarom (12b) leads to an odd interpretation because a CAUSE-CONSEQUENCE relation does not make sense: wet hair usually does not cause rain. (12) a. Petra’s haren zijn kletsnat. Dus heeft het net hard geregend. Petra’s hair is soaking wet. Dus it has been raining cats and dogs. b. #Petra’s haren zijn kletsnat. Daarom heeft het net hard geregend. #Petra’s hair is soaking wet. Daarom it has been raining cats and dogs. c. Petra’s haren zijn kletsnat. Blijkbaar heeft het net hard geregend. Petra’s hair is soaking wet. Blijkbaar it has been raining cats and dogs. d. Petra’s haren zijn kletsnat. Het heeft net hard geregend. Petra’s hair is soaking wet. It has been raining cats and dogs. The 40 sets were divided over four lists, according to a Latin square design, so that each list contained only one version of a set. 60 Filler items were added to the materials. These fillers consisted of 40 unrelated sentences and the 20 CAUSE-CONSEQUENCE relations with dus and daarom that were used in Experiment 1. Note, that because of these 20 CAUSECONSEQUENCE relations, the design also contained daarom relations that do make sense. Therefore, readers could not learn that this connective was always used inappropriately. The rest of the procedure was the same as in Experiment 1. 5.4.3 Results The data were treated as in Experiment 1. All observations that were two standard deviations above or below item and subject mean for each position and condition were excluded from the analysis. Following these criteria we removed 0.9% of the data (258 cases). Correct answers to the verification statements were given in 93% of the trials. Again, we analyzed the logtransformations of the measures: first pass reading times, right-bounded time, regression path duration, and total reading time. Means are reported in Table 3. The processing complexity of subjective causal relations|107 Table 3. Mean first pass reading times (FP), right-bounded time (RB), regression path duration (RP) and total reading time (TT) by Condition and region in Experiment 2.

Region 1 contains the different markers and is empty in the implicit condition (14). Region 2 consists of the first two subsequent words, in most cases an auxiliary and the subject. In the implicit condition, these are the first words of the second clause, which are inverted because Dutch main clauses require verb second word order. Notwithstanding this word order variation, Region 2 contains the same words in all conditions. Region 4 comprises the final words of the sentence and contains the key information to construct the causal relation. Region 3 consists of all the words in between regions 2 and 4. (13) |Dus 1 | heeft het 2 | net hard 3 | geregend. 4 | |Dus 1 | has it 2 | just heavy 3 | rained. 4 | (14) | ---- 1 | Het heeft 2 | net hard 3 | geregend. 4 | |----- 1 | It has 2| just heavy 2 | rained. 4 | Again we performed LMER analyses (Baayen, 2008) on the data, with subjects and items as crossed random effects and Marker (dus, daarom, 108|Chapter 5 blijkbaar and implicit) as fixed effect. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). For clarity’s sake, we will first discuss the effects of the different markers throughout the second sentence, after which we will go into the differences between implicit relations and the marked relations. The results at Region 1, containing the three markers, will not be discussed because the differences in length and frequency make it difficult to interpret any effects. The results in total time will be presented separately because this measure involves rereading, which is heavily influenced by the anomalous use of daarom. Dus versus daarom versus blijkbaar Dus led to longer processing times compared to blijkbaar and daarom at the first words following the connective (Region 2) and the subsequent region (Region 3). At Region 2, this effect surfaced in first pass reading times (dus vs. blijkbaar: ß=0.122, SE=0.030, t=4.10, p(MCMC)<0.001; dus vs. daarom: ß=0.071, SE=0.029, t=2.42, p(MCMC)<0.05), right-bounded time (dus vs. blijkbaar: ß=0.129, SE=0.030, t=4.28, p(MCMC)<0.001; dus vs. daarom: ß=0.067, SE=0.030, t=2.28, p(MCMC)<0.05) and regression path duration (dus vs. blijkbaar: (ß=0.133, SE=0.032, t=4.15, p(MCMC)<0.001); dus vs. daarom: (ß=0.074, SE=0.031, t=2.36, p(MCMC)<0.05). At Region 3, regression path duration was longer in dus relations compared to blijkbaar relations (ß=0.112, SE=0.042, t=2.66, p(MCMC)<0.01). At Region 4, the final words of the relation, we observed a longer regression path duration in daarom relations compared to dus and blijkbaar relations (daarom vs. dus: ß=0.141, SE=0.045, t=3.12, p(MCMC)<0.01; daarom vs. blijkbaar: ß=0.251, SE=0.0462, t=5.43, p(MCMC)<0.001). At this region, we also observed a longer regression path duration in dus compared to blijkbaar relations (ß=0.110, SE=0.046, t=2.41, p(MCMC)<0.05). In sum, arrived at the end of the relation, daarom led to longer rereading times of previous information compared to dus which in its turn led to longer rereading times compared to blijkbaar. Total Time Region 2 produced longer total reading times in dus and daarom relations compared to blijkbaar relations (ß=0.327, SE=0.038, t=8.63, p(MCMC)<0.001; ß=0.298, SE=0.0382, t=7.81, p(MCMC)<0.001 respectively). At Region 3 we observed longer total reading times in daarom compared to blijkbaar relations (ß=0.134, SE=0.037, t=3.66, p(MCMC)<0.001). Implicit versus marked relations Region 2, which consists of the first two words following the connective or the first two words of implicit relations, was processed faster in implicit relations The processing complexity of subjective causal relations|109 compared to both dus and daarom relations. This effect appeared in first pass reading times (implicit vs. dus: ß=-0.137, SE=0.030, t=4.49, p(MCMC)<0.001; implicit vs. daarom: ß=-0.066, SE=0.031, t=2.15, p(MCMC)<0.05) and in right-bounded time (implicit vs. dus: ß=-0.144, SE=0.031, t=4.63, p(MCMC)<0.001; implicit vs. daarom: ß=-0.076, SE=0.031, t=2.42, p(MCMC)<0.05). In regression path duration this difference was only significant for implicit compared to dus relations (ß=-0.124, SE=0.033, t=3.76, p(MCMC)<0.001). Similar effects appeared at Region 3. Compared to dus relations, this effect appeared in right –bounded time (ß=-0.143, SE=0.031, t=4.63, p(MCMC)<0.001) and regression path duration (ß=-0.168, SE=0.043, t=3.89, p(MCMC)<0.001). Compared to daarom relations, the effect surfaced in first pass reading times (ß=-0.108, SE=0.034, t=3.14, p(MCMC)<0.01), and right– bounded time (ß=-0.080, SE=0.036, t=2.23, p(MCMC)<0.05), and compared to blijkbaar in first pass reading times (ß=-0.076, SE=0.034, t=2.23, p(MCMC)<0.05). At the final words of the relations, we observed a shorter regression path duration for implicit compared to daarom relations only (ß=-0.193, SE=0.046, t=4.21, p(MCMC)<0.001). Total time Total time produced a similar pattern of results as the other measures. We observed a processing advantage for implicit relations compared to daarom and dus relations at Region 2 (ß=-0.267, SE=0.039, t=6.84, p<0.001; ß=0.296, SE=0.039, t=7.63, p<0.001). Compared to daarom, this advantage extended to Region 3 (ß=-0.092, SE=0.037, t=2.46, p<0.05). 5.4.4 Discussion The purpose of Experiment 2 was to get a better understanding of the cognitive mechanisms underlying the disadvantage in processing times for subjective compared to objective causal relations. As a first step, we set out to verify whether the processing asymmetry between dus and daarom, as observed in Experiment 1, can be interpreted as a reflection of their processing instructions about the type of causal relation they mark. The results from Experiment 2 suggest that this is indeed the case. We hypothesized that if daarom provides immediate cues to construct a CAUSECONSEQUENCE relation, readers are expected to experience difficulties when this interpretation is incompatible with the content of the text segments. This hypothesis was confirmed by our results. When daarom is used in ARGUMENT-CLAIM relations that do not allow for a CAUSECONSEQUENCE interpretation, such as (15), it initially leads to a processing advantage compared to dus. This replicates the results from Experiment 1. 110|Chapter 5 (15) #Petra’s haren zijn kletsnat. Daarom heeft het net hard geregend. #Petra’s hair is soaking wet. That’s why it has been raining cats and dogs. However, at the final words of relations such as (15), daarom leads to an increase in processing times in regression path duration. At this point in the sentence, readers can fully establish the CAUSE-CONSEQUENCE relation, as cued by daarom, and realize that it makes no sense. After all, wet hair does not usually cause any rain. As a result, readers start to look back to earlier parts of the relation in order find out what went wrong. Further evidence supporting the idea that dus provides instructions for the construction of a subjective causal relation comes from the processing difference between dus relations and implicit relations. As discussed in Chapter 2, a general finding in experimental studies is that causal connectives, and other signals of discourse structure, speed up the processing of the second clause of the causal relations (e.g. Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Millis & Just, 1994; Sanders & Noordman, 2000). However, dus did not lead to this facilitation effect. In line with the results from Kleijn, Mak, and Sanders (2011), we observed faster processing times at the beginning of S2 in implicit relations compared to dus-relations. This suggests that, rather than facilitating the construction of the relation between S1 and S2, dus induces additional cognitive processes. We proposed that these processes could be related to the representation of conclusions derived by reasoning, or to the representation of speaker involvement. We tested which of these components is responsible for the processing effects associated with subjective causal relations by comparing the processing of dus to the inferential evidential adverb blijkbaar. Blijkbaar is used to mark conclusions about events that the speaker has not witnessed himself, but that are derived by reasoning on the basis of the end state of those events. Yet, unlike dus, evidentials such as blijkbaar rely on objective evidence in the world, outside the speaker’s beliefs (Giannakidou, 2011; Nuyts, 2001). Therefore, the speaker is not responsible for the conclusion. We argued that if the processing difficulty of subjective causal relations is caused by the simple fact that they involve reasoning, irrespective of the degree of speaker involvement, blijkbaar and dus should lead to a similar delay in reading times compared to daarom. The results from Experiment 2, however, reveal that dus and blijkbaar do not induce comparable processing patterns. Readers need more time to process the first words after dus compared to both daarom and blijkbaar. While the effect compared to daarom is limited to these first words, compared to blijkbaar it extends to all subsequent regions. These results demonstrate that the processing effect associated with subjective causal relations cannot be explained by the fact that language users have difficulties in processing information derived by reasoning per se. The inferential evidential adverb blijkbaar also marks The processing complexity of subjective causal relations|111 reasoning, yet our data reveal that this adverb does not slow down the reading process in the way that dus does. In fact, the first region following blijkbaar even leads to faster processing times compared to daarom. The result from the comparison between blijkbaar and implicit relations did provide some evidence for our hypothesis that the representation of information derived by reasoning leads to a processing slowdown. Compared to implicit relations, blijkbaar did not lead to an initial speeding up effect. However, at the second region following blijkbaar, we did observe a processing slowdown compared to implicit relations. The fact that this effect does not arise immediately after blijkbaar, but one region later, suggests that readers do not immediately use all the semantic-pragmatic information encoded in this adverb. Why this effect should arise one region later is unclear. We will come back to this issue in the general discussion. Interestingly, daarom also led to longer processing times of S2 compared to implicit relations, but here the effect surfaced immediately after the connective. This is unexpected because (objective) causal connectives have been shown to speed up the processing of the second clause of a causal relation. One possible explanation for our result is related to the causal expectations that may have been triggered by our items. Because the relations in Experiment 2 were all created on the basis of inverted CAUSECONSEQUENCE relations, it may be the case that the first clauses of these relations created the expectation that a cause, or explanation, will be provided. For example, the interpretation of the relation in (16) without a connective is an objective CONSEQUENCE-CAUSE relation: S2 explains S1. (16) Petra’s haren zijn kletsnat. Het heeft net hard geregend. Petra’s hair is soaking wet. It has been raining cats and dogs. This interpretation is constructed on the basis of the two text segments together. However, the first clause “Petra’s hair is soaking wet” may already create the expectation that we are going to learn something about why this is relevant to know. Indeed, readers have been demonstrated to make online inferences about causes, rather than effects, because these inferences explain the current situation (Magliano, Bagget, Johnson, & Graesser, 1993). In addition, experiments by Mak and Sanders (to appear) show that such expectations immediately affect online processing. If daarom instructs readers that the following clause is to be interpreted as a consequence, this connective is unexpected when readers were in fact expecting a cause. This could explain the longer processing times for daarom relations compared to implicit relations. 112|Chapter 5 Taken together, our results suggest that the representation of conclusions, as based on reasoning, comes at a processing cost. However, the processing cost associated with subjective relations, as marked by dus, is much greater than the processing effect induced by blijkbaar; blijkbaar leads to faster processing times compared to dus. This suggests that the processing difficulty associated with subjective causal relations is not caused by the fact that they rely on reasoning per se. Instead, our data suggest that this effect may be caused by the fact that the speaker is responsible for the presented conclusion; it entails speaker involvement (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003; Stukker, Sanders, & Verhagen, 2009). To be more specific, these relations specify that the mind of a thinking subject is (at least in part) responsible for the presented conclusions and claims in a particular clause. As such, subjective connectives such as dus function as explicit cues to the interlocutor to take this mind into account in the representation (and possibly also the evaluation) of these conclusions. To verify whether this property of subjective causal relations is responsible for the observed processing effects associated with subjective causal relations, we conducted a third experiment in which we compared the processing of dus and blijkbaar to the epistemic modal waarschijnlijk (probably). Similar to dus and blijkbaar, waarschijnlijk marks (possible) conclusions. However, being a modal, waarschijnlijk provides additional information about the speaker’s estimation of the probability of these conclusions. The speaker explicitly signals that the following proposition is highly likely, yet he or she is not fully committed to its truthfulness (Nuyts, 2004, p.61) (17a). This estimation relies on all sorts of knowledge available to the speaker, such as world knowledge, common sense but also personal experiences, ideas and beliefs. By using waarschijnlijk the speaker indicates that he or she judges a scenario to be likely. We therefore propose that conclusions marked by waarschijnlijk carry more speaker involvement than conclusions marked by blijkbaar. Yet, it has been recognized that modal expressions, such as waarschijnlijk, are not always tied to the speaker; they can represent judgments that are shared by others (e.g. Ernst 2009:540; Lyons, 1977; Nuyts, 2001, 2004). Given that by using waarschijnlijk the speaker takes a safe distance from the presented conclusion, we propose that it involves less speaker involvement than dus. In line with ideas on relative degrees of speaker involvement (Pander Maat & Degand, 2001) we propose that waarschijnlijk takes up an intermediate position between dus and blijkbaar (17). (17) Degree of speaker involvement dus > waarschijnlijk > blijkbaar The processing complexity of subjective causal relations|113 If the notion of speaker involvement is related to the processing effects associated with subjective causal relations, we expect that our classification of dus, blijkbaar, and waarschijnlijk along the lines of speaker involvement is reflected in online processing. Waarschijnlijk should therefore lead to a delay in processing times compared to blijkbaar, but to faster processing times compared to dus. An additional difference between waarschijnlijk on the one hand, and dus and blijkbaar on the other, is that it presupposes doubt. In ARGUMENT-CLAIM relations as used in Experiment 2, in which reasoning occurs from effect to cause, waarschijnlijk implies that there are alternative causes (Cummins, 1991, 1995; Noordman & De Blijzer, 2000) that could in principle also be responsible for the effect described in the first clause of the relation (18). (18) Petra’s haren zijn kletsnat. Waarschijnlijk heeft het net hard geregend (maar misschien heeft ze haar hoofd net onder de kraan gehad). Petra’s hair is soaking wet. Waarschijnlijk it has been raining cats and dogs. (But maybe she just put her head under the tap) If waarschijnlijk activates such alternative causes during online processing, we would expect language users to experience difficulties when this adverb is used in causal scenarios in which there is no doubt. By way of illustration, consider example (19). People usually get drunk when they drink too much alcohol. One could, of course, always come up with an implausible alternative cause for getting drunk. For example, one of the alternative causes for getting drunk that surfaced in our pretest was “eating liquor filled chocolates”, which received a low probability score. In this situation, there really are no plausible alternative causes and the use of waarschijnlijk should be inappropriate. Readers are expected to realize this towards the end of the second clause. Arrived at the end of the second clause, readers have enough information to construct the causal relation and will be able to evaluate the alternative causes, which there aren’t in case of (19). (19) Na een avondje stappen kwam Fabio stomdronken thuis. Waarschijnlijk had hij te veel alcohol gedronken. After a night out, Fabio came home completely drunk. Waarschijnlijk he drank too much alcohol. By using dus and blijkbaar (20), on the other hand, the speaker suggests that there are no alternative causes (with dus because the speaker believes so, and with blijkbaar because it implies that there is objective evidence that points into that direction). Therefore, the conclusion in S2 is presented as the only sensible one. 114|Chapter 5 (20) Na een avondje stappen kwam Fabio stomdronken thuis. Dus / Blijkbaar had hij te veel alcohol gedronken. (# maar misschien heeft hij heel veel kersenbonbons gegeten) After a night out, Fabio came home completely drunk. Dus / Blijkbaar he drank too much alcohol. (# but maybe he ate too many liqueur bonbons) The use of dus and blijkbaar should therefore cause problems in scenarios such as (21) where in fact many alternative causes apply. However, these scenarios should not cause any problems if they are marked by waarschijnlijk. (21) Na een avondje stappen kwam Fabio met een taxi naar thuis. Dus / blijkbaar had hij te veel alcohol gedronken. After a night out, Fabio came home in a taxi. Dus / Blijkbaar he drank too much alcohol. 5.5 Experiment 3 5.5.1 Participants Forty undergraduate students from Utrecht University participated in the experiment (36 female, mean age 21.2 age range 18–27 years). These participants did not take part in any of the other experiments described in this study. All participants were native speakers of Dutch and were paid for their participation. 5.5.2 Materials and design The materials consisted of 42 short narratives of 3 sentences in which we embedded ARGUMENT-CLAIM relations marked by dus, waarschijnlijk and blijkbaar. Scenarios with and without alternative causes were constructed for each item, see (22) (see Appendix 4 for more examples). All items have the same structure. The first sentence sets the stage and provides background information underlying the conclusion. The second sentence describes a situation that leads to the speaker’s conclusion about the cause of that situation, which is presented in the final sentence. The first and second sentences of the text were manipulated to obtain the different scenarios. For example, in the scenario with no alternative causes (NO-AC), the conclusion that Fabio drank too much alcohol is the only plausible cause for getting drunk. In the scenario with alternative causes (AC) on the other hand, the conclusion that Fabio drank too much alcohol is not the only plausible cause for coming home in a taxi. Other causes (lost his keys, flat tire etc.) could be equally plausible. Note that even though the first clause of the causal relation is different in the two scenarios, the target sentence is the same in all conditions. The processing complexity of subjective causal relations|115 (22) No Alternative Causes (NO-AC) Met Oud en Nieuw ging Fabio naar een smartlappenfeest in Den Haag. De volgende ochtend kwam hij stomdronken thuis. Dus / Waarschijnlijk / Blijkbaar had hij te veel alcohol gedronken. On New Year’s Eve Fabio went to a tearjerker festival in The Hague. The next morning he came home completely drunk. Dus / Waarschijnlijk / Blijkbaar he drank too much alcohol. Alternative Causes (AC) Gisteravond ging Fabio naar een verjaardagsfeestje. Uren later kwam hij met een taxi naar huis. Dus / Waarschijnlijk / Blijkbaar had hij te veel alcohol gedronken. Yesterday night Fabio went to a birthday party. Hours later he came home in a taxi. Dus / Waarschijnlijk / Blijkbaar he drank too much alcohol. The 42 sets were divided over six lists, according to a Latin square design, so that each list contained only one version of a set. 46 Filler items were added to the materials, which consisted of 46 unrelated short narratives. The items were presented in four blocks of stimuli. Line breaks were placed as in example (23). We made sure that the connective was not situated at the end or beginning of a line. Length differences between the target line and the line preceding it were kept to a minimum to avoid effects of systematic differences in visual presentation. Verification statements were randomly divided over the stimuli and appeared after 25% of the items. Participants were informed to respond to these statements by pressing the ‘yes’ or ‘no’ button on the button box. The rest of the procedure was the same as in Experiments 1 and 2. (23) Met Oud en Nieuw ging Fabio naar een smartlappenfeest in Den Haag. De volgende ochtend kwam hij stomdronken thuis. Dus had hij te veel alcohol gedronken. [On New Year’s Eve went Fabio to a tearjerker festival in The Hague. The next morning came he completely drunk home. Dus had he too much alcohol drank.] 5.5.3 Pretest An offline pretest was conducted to verify whether our manipulation of the presence or absence of alternative causes was successful. To test the underlying relation, but avoiding effects of the different markers, we replaced the markers that introduce the final clause with the phrase I think that (24). This resulted in two versions of each item (one with, and one 116|Chapter 5 without alternative causes). The items were divided over two lists so that each list contained only one version of an item. (24) Met Oud en Nieuw ging Fabio naar een smartlappenfeest in Den Haag. De volgende ochtend kwam hij stomdronken thuis. “Ik denk dat hij te veel alcohol had gedronken.” On New Year ’s Eve Fabio went to a tearjerker festival in The Hague. The next morning he came home completely. “I think he drank too much alcohol.” 33 Students of Utrecht University, who did not participate in any of the other experiments described in this study, were presented with these scenarios. They were asked to rate on a 5-point Likert-scale how probable it was that the speaker’s conclusion (presented in quotation marks in the example) was the actual cause of the preceding situation. Also, if possible, they had to provide an alternative cause for that situation and again rate its probability. A NO-AC item was considered to be successful if its mean probability score was 4 or higher and its alternative cause received a probability score of 2 or lower. Note that this mean score is based on the cases in which our raters were able to come up with an alternative. However, in cases where no alternative was provided, an alternative probability score of zero applies. Therefore, items with an alternative probability score of more than 2.0 were discarded if more than half of the raters (8 or more) could come up with an alternative cause. In doing so, only items were included in which the causes were perceived as highly likely. And even if people were able to provide an alternative cause when they are stimulated to do so, this cause was judged as unlikely. In the AC condition, an item was considered to be successful if at least two thirds of the raters (11 or more) could come up with an alternative cause. Items that were rejected on the basis of these criteria were adjusted and retested until they fitted the requirements. 5.5.4 Results The data were treated as in Experiments 1 and 2. All observations that were two standard deviations above or below item and subject mean for each position and condition (101 cases) were excluded from the analysis.

Again, we analyzed the log-transformations of the measures first pass reading times, right-bounded time, regression path duration, and total reading time. Means are reported in Tables 4 and 5. Similar to Experiments 1 and 2, we divided the target sentence into 4 regions for analysis, illustrated by example (25). Region 1 is the conclusion marker (dus, blijkbaar or waarschijnlijk) and Region 2 consists of the first two subsequent words, in most cases an auxiliary and the subject. Region 4 comprises the final words of the sentence and contains the key information to construct the causal relation. Region 3 consists of all the words in between regions 2 and 4. (25) |Dus / Blijkbaar / Waarschijnlijk 1 | had hij 2 | te veel 3 | alcohol gedronken 4 | |Dus / Blijkbaar / Waarschijnlijk 1 | had he 2| too much 3 | alcohol drank 4 | We performed LMER analyses (Baayen, 2008) on the data, with subjects and items as crossed random effects. We modeled the fixed effect of Scenario (alternative causes vs. no alternative causes), Marker (dus vs. blijkbaar vs. waarschijnlijk) and the interaction between these factors. Markov Chain Monte Carlo (MCMC) sampling was used to estimate p values (Baayen, 2008). There were no significant interactions between Marker and Scenario, we obtained only main effects. We will first discuss the main effects of Scenario and then go into the main effects of Marker throughout the target sentence. The results at Region 1, containing the different markers, will not be discussed because the differences in length and frequency make any effects difficult to interpret. Main effects of Scenario At Region 4, the final words of the conclusion, a main effect of Scenario was observed in regression path duration. This region was processed slower in scenarios with alternative causes compared to scenarios without alternative causes (ß=0.128, SE=0.036, t=3.51, p(MCMC)<.001). The same effect also appeared in total time at Region 3 (ß=0.109, SE=0.025, t=4.29, p(MCMC)<.001). Main effects of Marker At Region 2, the words following the markers, reading times were longer in dus conclusions compared to blijkbaar and waarschijnlijk conclusions. This effect appeared in first pass reading times (dus vs. blijkbaar: ß=0.074, SE=0.023, t=3.22, p(MCMC)<.01; dus vs. waarschijnlijk: ß=0.071, SE=0.022, t=3.16, p(MCMC)<.01), right-bounded time (dus vs. blijkbaar: ß=0.084, The processing complexity of subjective causal relations|119 SE=0.023, t=3.58, p(MCMC)<.001; dus vs. waarschijnlijk: ß=0.092, SE=0.023, t=3.98, p(MCMC)<.001), regression path duration. (dus vs. blijkbaar: ß=0.064, SE=0.026, t=2.43, p(MCMC)<.05; dus vs. waarschijnlijk: ß=0.104, SE=0.026, t=4.02, p(MCMC)<.001) and total time (dus vs. blijkbaar: ß=0.378, SE=0.033, t=11.58, p(MCMC)<.001; dus vs. waarschijnlijk: ß=0.381, SE=0.033, t=11.57, p(MCMC)<.001). Region 3, the prefinal region, produced a slightly different pattern of results. We observed longer first pass reading times in waarschijnlijk compared to dus conclusions (ß=0.064, SE=0.027, t=2.37, p(MCMC)<.05) and longer reading times in right-bounded time for waarschijnlijk compared to blijkbaar conclusions (ß=0.083, SE=0.029, t=2.91, p(MCMC)<.01). At this region, we also obtained a longer regression path duration for dus and waarschijnlijk compared to blijkbaar (dus vs. blijkbaar: ß=0.090, SE=0.035, t=2.56, p(MCMC)<.01; waarschijnlijk vs. blijkbaar: ß=0.094, SE=0.035, t=2.69, p(MCMC)<.01) and a longer total time for dus compared to blijkbaar conclusions (ß=-0.091, SE=0.031, t=2.93, p(MCMC)<.01) At Region 4, the final words of the conclusion, we observed a similar pattern as in Region 2. Dus conclusions led to longer reading times in regression path duration compared to waarschijnlijk (ß=0.169, SE=0.045, t=3.79, p(MCMC)<.001) and blijkbaar (ß=0.157, SE=0.044, t=3.54, p(MCMC)<.001) conclusions. 5.5.6 Discussion The purpose of Experiment 3 was to test whether the notion of speaker involvement explains the processing cost of subjective causal connectives and relations. In order to answer this question we compared the processing patterns of dus and blijkbaar to the epistemic modal adverb waarschijnlijk. We proposed that dus encodes a high level of speaker involvement whereas blijkbaar encodes a low level of speaker involvement, and waarschijnlijk takes up an intermediate position. The pattern of results that arises from Experiment 3 is consistent with this division along the lines of speaker involvement. As in Experiment 2, dus led to a disadvantage in processing time compared to blijkbaar at the entire second clause (Regions 2, 3, and 4). Compared to waarschijnlijk, dus led to longer processing times at Regions 2 and 4. At Region 3, however, there was no difference between dus and waarschijnlijk, except for a single measure. First pass reading times at this region were longer for waarschijnlijk, compared to dus. At this region waarschijnlijk also led to longer processing times compared to blijkbaar in first pass reading times and in regression path duration. Figures 1 and 2 illustrate the differences in right-bounded time and regression path duration between blijkbaar on the one hand, and dus and waarschijnlijk on the other. 120|Chapter 5 45 40 Difference in fixation time 35 30 25 dus 20 waarschijnlijk 15 10 5 0 -5 2 3 4 Region Figure 1.

Difference in regression path duration for dus and waarschijnlijk compared to blijkbaar per region. These results suggest that readers are sensitive to the degree of speaker involvement encoded in waarschijnlijk. However, this effect arises later compared to dus. Note that this is the same position at which we observed the effects of blijkbaar compared to implicit relations in Experiment 2. Hence, both adverbs affect online processing at the same position in the The processing complexity of subjective causal relations|121 sentence, which suggests that this difference in comparison with connectives may be related to their grammatical properties. Therefore, the delayed effects could be explained by the fact that waarschijnlijk and blijkbaar, which are both non-connective adverbs, do not have the same integrative function as connectives. We will come back to this in the general discussion. We propose that the processing slowdown induced by waarschijnlijk is a reflection of speaker involvement. But before we discuss this in more detail, we need to consider an alternative explanation for this effect. Being a modal, waarschijnlijk provides information about the probability of the following proposition. By using waarschijnlijk, the speaker indicates that this probability is high, yet there is room for an alternative, there is doubt. With respect to the ARGUMENT-CLAIM relations manipulated in the present study, in which reasoning occurs from effect to cause, waarschijnlijk implies that there are alternative causes. It could therefore be argued that the processing effect of waarschijnlijk is caused by the fact that readers have to activate these alternatives. We hypothesized that if language users make use of this information during online processing, waarschijnlijk should cause problems when the presented conclusion is necessarily true. Therefore, in relations such as (26), in which there really are no alternative causes, readers are expected to experience processing difficulties towards the end of the second clause. At this point in the sentence, the relation can be fully constructed and evaluated against the world knowledge of the reader. (26) Met Oud en Nieuw ging Fabio naar een smartlappenfeest in Den Haag. De volgende ochtend kwam hij stomdronken thuis. Waarschijnlijk had hij te veel alcohol gedronken. On New Year’s Eve Fabio went to a tearjerker festival in The Hague. The next morning he came home completely Waarschijnlijk drunk. he drank too much alcohol. Conversely, dus and blijkbaar presuppose that there are no alternative causes; there is no doubt. The conclusions in the second clause are presented as the only sensible ones. We therefore hypothesized that dus and blijkbaar should lead to processing difficulties in relations with many alternative causes, such as (27). (27) Gisteravond ging Fabio naar een verjaardagsfeestje. Uren later kwam hij met een taxi naar huis. Blijkbaar / Dus had hij te veel alcohol gedronken. Yesterday night Fabio went to a birthday party. Hours later he came home in a taxi. Dus / Blijkbaar he drank too much alcohol. 122|Chapter 5 The results from Experiment 3 reveal that the presence of alternative causes does not interact with the type of marker used in ARGUMENTCLAIM relations. Contrary to what we hypothesized, waarschijnlijk did not cause any processing difficulties in conclusions that are necessarily true; neither did it facilitate the processing of conclusions that are questionable. These results suggest that the presence of waarschijnlijk does not lead to the activation of alternative causes. Rather, it seems that what is most informative about waarschijnlijk is not the notion of doubt, but the high probability of the following proposition. The conclusions presented in scenarios without alternative causes are highly likely, and therefore compatible with the probability indicated by waarschijnlijk. Conclusions in scenarios with alternative causes, however, are necessarily less probable because there are alternatives. This is confirmed by the results from our offline judgment task, which revealed an overall lower probability score for the conclusion in causal scenarios with alternative causes compared to scenarios without alternative causes. The online data reveal that our participants were sensitive to these differences. Overall, readers took more time to process conclusions in scenarios with alternative causes compared to scenarios without alternative causes. This mainly resulted in a longer regression path duration at the final text region and in the total reading times of the entire conclusion. The position of these effects, and the measures in which they arise, suggests that readers take more time rereading conclusions in scenarios with alternative causes. However, readers did not differentiate between dus, blijkbaar and waarschijnlijk when they evaluated the conclusions against their world knowledge. This suggests that the notion of doubt, implied by waarschijnlijk, does not affect the processing and evaluation of ARGUMENT-CLAIM relations. These observations therefore support our interpretation of the processing slowdown induced by waarschijnlijk as a reflection of speaker involvement rather than doubt. 5.6 General Discussion The three eye-tracking experiments reported in this study contribute to our understanding of the cognitive mechanisms underlying the complexity of subjective causal relations. Previous studies in English and Dutch have reported longer processing times for subjective CLAIM-ARGUMENT compared to objective CONSEQUENCE-CAUSE relations (Chapter 3-4; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997). The main difference between English and Dutch is that in English, the connective because can be used in both subjective and objective relations whereas Dutch has two connectives, want and omdat, that specialize in subjective and objective causal relations respectively. Therefore, in Dutch the The processing complexity of subjective causal relations|123 effect of subjectivity arises immediately after the subjective connective want is processed. On the basis of these studies, however, it remained unclear whether the effect of subjectivity is to be attributed to a reanalysis of S1 as a conclusion, or a psychological event (Traxler, Sanford, Aked, & Moxey, 1997), or whether it arises because the representation of these conclusions is inherently complex. Since backward and forward causal relations are considered to be conceptually similar (Sanders, Sanders, & Sweetser, 2012), we tried to disentangle these factors by investigating the online processing of forward subjective and objective causal relations marked by dus and daarom respectively. The advantage of this setup is that a conclusion marked by dus does not involve a reanalysis of the conclusion because the conclusion follows the connective. Experiment 1 revealed that, similar to the processing asymmetry between want and omdat, the connective dus leads to longer processing times compared to daarom at the immediately following words. These results reveal that the delay in processing times for subjective causal relations compared to objective causal relations cannot be explained in terms of a reanalysis of the first clause of those relations as claims or conclusions. Instead, our data suggest that subjective relations are inherently more complex. Experiments 2 and 3 shed more light on this complexity by focusing on different pieces of information that are encoded in dus. We hypothesized that the complexity of subjective causal relations may consist of at least two components. Given that claims and conclusions are products of reasoning, it may be the case that the cognitive complexity associated with subjective causality is related to this underlying process. Reasoning can be defined as a simulation of the world (Johnson-Laird, 2010). This process involves the construction of different mental models compatible with a situation in the real world, on the basis of which a conclusion is drawn. In addition, conclusions as part of subjective causal relations entail speaker involvement (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003); a thinking subject takes responsibility for the presented conclusion. This subject can be the speaker, author, or any third person character whose reasoning is presented. For sake of convenience we will continue to refer to the speaker in this discussion. Experiment 2 revealed that the cognitive complexity of subjective causal relations is not explained by the simple fact that these relations involve reasoning. Similar to dus, the inferential evidential adverb blijkbaar relies on reasoning, yet this adverb does not lead to longer processing times compared to the objective connective daarom. The results of Experiment 3, in which we compared the processing of dus and blijkbaar to the modal adverb waarschijnlijk, suggest that it is the relative degree of speaker involvement 124|Chapter 5 in the presented conclusions that determines the processing complexity of subjective causal relations. We argued that dus conclusions are directly linked to the mind of the speaker. As such, dus signals that this mind is to be taken into account in the representation (and possibly the evaluation) of those conclusions. Blijkbaar, on the other hand, emphasizes that the speaker’s personal beliefs and opinions are not involved in the conclusion; it signals a certain distance from the speaker’s mental world. It implies that there is perceptible evidence in the world (Giannakidou, 2011; Nuyts, 2001) that forces the speaker to draw that particular conclusion. As such, the speaker does not take responsibility for that conclusion. We hypothesized that if speaker involvement is a determining factor underlying the longer processing times for dus compared to daarom and blijkbaar, other sentence modifiers that also signal speaker involvement, such as the modal adverb waarschijnlijk, should have a similar effect. Waarschijnlijk provides the speaker’s evaluation of the probability of the following proposition. Yet, modals such as waarschijnlijk can also represent evaluations that belong to people other than the speaker (e.g. Ernst 2009, p.540; Lyons, 1977; Nuyts, 2001, 2004). Also, by using waarschijnlijk, the speaker might not fully commit him or herself to the truthfulness of the proposition: he or she takes a safe distance. We therefore proposed that waarschijnlijk signals more speaker involvement than blijkbaar, but less speaker involvement than dus. The processing effects observed in Experiment 3 are consistent with this division along the lines of speaker involvement. We observed longer processing times after waarschijnlijk compared to blijkbaar, yet dus led to even longer processing times. The notion of subjectivity as speaker involvement is not new. This term already been used to capture the difference between subjective and objective causal relations (Pander Maat & Degand, 2001, Pander Maat & Sanders, 2000, 2001). In these studies, speaker involvement has been described as “…referring to the degree to which the present speaker is implicitly involved in the construal of the relation” (Pander Maat & Degand, 2001, p.214), or “the involvement of the speaker in the interpretation of the relation” (Pander Maat & Sanders, 2001, p.253). Note, however, that the original definitions are somewhat misleading because they suggest that speaker involvement only concerns involvement of the speaker. Yet, the processing data discussed in the current study reveal that third person mental states (John thinks, according to John) have the same ability to cancel out the processing effects in the second clause of subjective causal relations as epistemic modals (perhaps, maybe), which implicitly refer to the speaker. This confirms that speaker involvement concerns any character in a discourse whose reasoning is presented (Sanders, Sanders, & Sweetser, 2009). Pander Maat and The processing complexity of subjective causal relations|125 Degand also refer to involvement of the concluder, who by default is the speaker himself (2001, p.221). In addition, according to the original definitions, speaker involvement is conceived as a property of relations. However, the experimental evidence on backward causal relations suggests that it is not necessarily the relational aspect that causes processing problems, but the link between the proposition comprising the conclusion and the mind of the thinking subject. The effects of subjectivity disappear when the first clause of the subjective causal relation is marked by phrases such as perhaps and according to John. These phrases do not build causal relations between two segments, but signal the fact that a thinking subject is responsible for the proposition at hand. This suggests that speaker involvement, as an explanation for the observed processing effects in subjective causal relations, may be a property of propositions rather than relations. At this point we can only speculate about why speaker involvement should come at a processing cost. From a communicative perspective it seems relevant to know whether an utterance conveys a description of a situation in the real world, or whether it is derived from the mental world of a thinking subject. Cues of speaker involvement could therefore function as a signal to the reader, or listener, that the information should be interpreted against the background of this mental world. As discussed in the introduction of this chapter, the construction of the representation of this mental world could in itself be cognitively demanding. However, the increased processing load could also be explained by the placement of information within the representation of the relevant mind, the maintenance of that representation next to the representation of the real world, or by the fact that this information bound to specific mental worlds requires a more careful evaluation on behalf of the reader. In Chapter 6 we will further elaborate on these processes. It is remarkable that the effect of subjectivity induced by causal connectives has a different time course than non-connective adverbs: the disadvantage in processing time induced by dus surfaced at the region immediately following the connective whereas the effect of waarschijnlijk surfaced one segment later. This pattern of results reveals that the information about the relative degree of speaker involvement encoded in these devices is put to use at different positions in the sentence. One explanation for this difference is that connectives may induce immediate effects of subjectivity because they have an integration function (Noordman & Vonk, 1997) whereas non-connective adverbs do not. There is some evidence from neuro-linguistic experiments that suggests that connectives and non-connective adverbs differently affect online processing. German ERP studies by Brehm (2005) revealed that connectives 126|Chapter 5 lead to a Late Anterior Negativity (LAN) at the immediately following word compared to non-connective adverbs. This effect was interpreted as reflecting the immediate integration of the first sentence as the external argument of a two-place relation. Indeed, while connectives by default establish links between two pieces of text, non-connective adverbs, such as waarschijnlijk and blijkbaar, do not necessarily do this. They can easily be used out of the blue, without any linguistic context, in single declarative sentences (28a) (29a), whereas this is impossible or at the very least more difficult for dus or daarom (28b) (29b)3. (28) a. Waarschijnlijk ga ik zondag naar het strand. Waarschijnlijk I’m going to the beach tomorrow. b. ?Dus / Daarom ga ik zondag naar het strand. ? Dus I’m going to the beach tomorrow. (29) (speaker looks at his watch) a. Oeps, blijkbaar is het niet gelukt om op tijd te komen. Oops, blijkbaar I failed to be in time. b. ?Oeps, dus / daarom is het niet niet gelukt om op tijd tekomen. ? Oops, dus / daarom I failed to be in time. Our data support the idea that adverbs such as waarschijnlijk and blijkbaar have a different function in online processing compared to connectives. The effect of subjectivity induced by waarschijnlijk in Experiment 3 surfaced later compared to the connective dus. Crucially, this was the same position in the sentence where we observed the processing delay in reading times for blijkbaar compared to implicit relations in Experiment 2. This pattern of results suggests that information encoded in adverbs that influences the status of the entire clause may not be put to use immediately when they are encountered. Because non-connective adverbs do not require the construction of a relation between two clauses, it could be the case that interclausal integration starts only when the content of the second clauses reveals that a relation between S1 and S2 needs to be established. At this point in the sentence, information about the status of clauses as conclusions derived by reasoning (in case of blijkbaar) or as conclusions that entail speaker involvement (in case of waarschijnlijk) could become relevant. Conversely, because causal connectives trigger the immediate integration of two clauses, information about the degree of subjectivity underlying one of these clauses has an immediate effect in online processing. Further results reported in this study support the hypothesis that causal connectives lead to a more active integration process compared to 3 It is remarkable that dus can be used in these situations if it functions as a discourse marker, with a specific intonation pattern and followed by a pause. The processing complexity of subjective causal relations|127 adverbs. Recall that in Experiment 1, dus leads to longer processing times compared to daarom at the first words following the connectives, but not at later regions, as compared to waarschijnlijk and blijkbaar in Experiments 2 and 3. This suggests that connectives induce longer processing times at the end of the causal relation compared to adverbs. This effect is reminiscent of the ‘inference effect’ (Cozijn, 2000) or ‘world knowledge integration’ effect (Cozijn, Noordman, & Vonk, 2011) attributed to causal connectives, as discussed in Chapter 2. In addition, the data from Experiment 2 shed new light on the integration effect associated with causal connectives. A typical finding in experimental studies is that causal connectives, and other signals of discourse structure, speed up the processing of the beginning of the second clause (e.g. Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Millis & Just, 1994; Sanders & Noordman, 2000). Our results suggest that this facilitation does not arise when 1) the relation expressed by the connective violates the causal expectations elicited by S1 (daarom vs. implicit relations) and 2) the relation expressed by the connective is more complex, as a result of speaker involvement, than the relation established without a connective (dus vs. implicit relations). These results reveal that interclausal integration is not a static operation, but a complex process that interacts with factors such as discourse expectations and subjectivity. More research is required to fully understand the dynamic process of interclausal integration and how it is reflected in online processing. Chapter 6 Conclusion Coherence relations and their linguistic markers play a significant role in the study of discourse processing and comprehension. A number of studies have shown that the presence of coherence markers, such as connectives, in a text facilitates the construction of a coherent representation. That is, these markers specify the coherence relations that need to be constructed between text segments. This information leads to faster processing times of the information following a connective (Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Kamalski, Sanders, Lentz, & Zwaan, 2008; Millis, Golding, & Barker, 1995; Millis & Just, 1994; Noordman & Vonk, 1997; Sanders & Noordman, 2000), and to a better a text representation (Degand & Sanders, 2002; Hyönä & Lorch, 2004; Loman & Mayer, 1983; Lorch & Lorch, 1986; McNamara, Kintsch, Songer, & Kintsch, 1996; Meyer, Brandt, & Bluth, 1980; Millis & Just, 1994; Sanders, Land, & Mulder, 2007). Therefore, connectives are proposed to function as processing instructions (e.g. Britton, 1994; Gernsbacher, 1997; Murray, 1995; Sanders & Spooren, 2007). The main purpose of the current study was to get a better understanding of the type of information that is encoded in these processing instructions, and how this information affects online discourse processing. More specifically, we focused on causal connectives and investigated whether they provide cues about the fine-grained distinction between subjective and objective causal relations (or epistemic and content relations in terms of Sweetser (1990)). This question is relevant for two reasons. First, in many languages of the world causal connectives seem to specialize in either subjective or objective causal relations (Stukker & Sanders, 2012). And second, subjective causal relations are assumed to be more complex than objective causal relations (Sanders, Spooren, & Noordman, 1992). This complexity is associated with longer processing times in reading experiments (Noordman & De Blijzer, 2000; Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997). In the current dissertation we have investigated these issues from a processing perspective, by focusing on Dutch forward and backward causal connectives (dus versus daarom and want versus omdat). In this final chapter we will discuss our main findings and explore ideas for future research. 6.1 Summary of results 6.1.1 Causal connectives as processing instructions 130|Chapter 6 Causal connectives are assumed to provide processing instructions about the causal relation that needs to be constructed between the pieces of text. So far, no other studies have investigated whether such processing instructions are to be taken as general instructions about the causal nature of the coherence relation, or whether they also convey subtle information about the degree of subjectivity of that relation. Previous research on the processing of English subjective and objective causal relations (Traxler, Bybee, & Pickering, 1997; Traxler, Sanford, Aked, & Moxey, 1997) focused on subjectivity as a property of relations, and compared the processing of subjective and objective causal relations that were marked by the same connective. Kamalski, Lentz, Sanders, and Zwaan (2008) investigated the effects of various subjective and objective connectives and cue phrases on discourse processing by comparing explicit versus implicit versions of a text. In the current study, however, we directly compared the processing effects of subjective and objective connectives and investigated this matter in a series of eye-tracking experiments. While the presence of a causal connective is generally assumed to speed up processing times, we found that this is not the case for subjective causal connectives. In Chapter 2 we first explored whether the notion of subjectivity could play a role in the processing of causal connectives, and started out by focusing on the Dutch causal connectives want and omdat in comparison to the English connective because. The latter is used to mark both subjective and objective causal relations in English, and is therefore underspecified with respect to the degree of the subjectivity of the causal relation it marks (e.g. Couper- Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990). Conversely, the Dutch connective want is a prototypical marker of backward subjective causal relations, while omdat is a prototypical marker of backward objective causal relations (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009; submitted; Verhagen, 2005). In addition, there is a syntactic difference between these two connectives: want is a coordinating connective, whereas omdat introduces a subordinate clause. As we will show later on in this chapter, this syntactic difference cannot be used as a plausible explanation for the effects obtained in our experiments. Given that want, but not omdat, can be used in all relational contexts in which because occurs, we formulated the following research question: RQ1 Is the Dutch connective want comparable to English because with respect to its processing instructions? We tested this question in an eye-tracking experiment in which we used a Dutch version of the items from Traxler, Bybee, and Pickering (1997) in which the connective want marked both subjective (1b) and objective (1a) Conclusion|131 causal relations. Note that these relations are perfectly fine in Dutch when they are both marked by want. (1) a. Hanneke was buiten adem, want ze was vier trappen afgerend om de post te halen. [Hanneke was out of breath, want she was four stairs ran down to the mail get.] Hanneke was out of breath, because she ran down four stairs to get the mail. b. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. [Hanneke was in a hurry, want she was four stairs ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. In the original English study subjective causals with because were found to lead to longer processing times compared to objective causals with because. This effect arose right before the end of the second clause. The position of this effect is fully compatible with the assumption that because does not provide information about the degree of subjectivity of the causal relation it marks. Language users can therefore only derive this information from the propositional content, which explains why the effects of subjectivity arise relatively late in the second sentence. We found that when want marks both subjective and objective causal relations in Dutch, there is no processing difference between subjective and objective causal relations. This suggests that want and because are not similar in terms of their processing instructions. One possible explanation for this (null) effect put forward in Chapter 2 is that want, being a prototypical marker of subjective causal relations, induces a subjective representation of (inherently) objective relations such as (1a). As such, readers may treat S1 as a claim (followed by an argument) rather than a consequence (followed by a cause). In Chapter 3 we verified this explanation by testing the following research question: RQ2 Is the distinction between subjective and objective causal connectives, as distinguished in corpus-based studies on the semantic-pragmatic characteristics of connectives, relevant in online processing? And if so, what is the time course of this effect? In Experiment 1 we used the same materials as in Chapter 2, with the only difference that the objective connective omdat marks the objective condition (2). (2) Hanneke was buiten adem, omdat ze vier trappen was afgerend om de post te halen. [Hanneke was out of breath, omdat she four stairs was ran down to the mail get.] Hanneke was out of breath, because she ran down four stairs to get the mail. 132|Chapter 6 This time we did replicate the delay in processing times for subjective compared to objective causal relations as observed in English with Dutch subjective and objective causal relations marked by want and omdat respectively. In addition, we found that the slowing down effect in Dutch arises much earlier, directly at and after the connective want. At this point in the sentence, readers do not yet have enough information to construct the causal relation from the content, which shows that the effect must be caused by the semantic-pragmatic properties of the connectives. The results from Experiment 2 confirmed that this effect is a reflection of the difference between want and omdat in terms of subjectivity. We found that the processing delay in subjective causal relations disappears when the reader is explicitly cued about the status of S1 as a claim, or conclusion, by means of mental state predicates such as volgens Peter (according to Peter) (3). (3) Volgens Peter had Hanneke haast, want ze was vier trappen afgerend om de post te halen. [According to Peter Hanneke was in a hurry, want she was four stairs ran down to the mail get.] According to Peter, Hanneke was in a hurry, because she ran down four stairs to get the mail. These results replicate earlier studies in English (Traxler, Sandford, Aked & Moxey, 1997), and reveal that the relative complexity of subjective causal relations in English and Dutch has to be related to the representation of S1 as someone’s reasoning, or claim, rather than an actual event in the world. This finding allows us to exclude an alternative explanation for the processing asymmetry between want and omdat observed in Experiment 2 in terms of their syntactic properties, that is, as coordinating or subordinating connective. The addition of according to Peter to the first clause of a want relation does not alter the syntactic properties of want, yet does eliminate the processing asymmetry between want and omdat. Therefore this asymmetry cannot be explained by the syntactic differences between the two connectives. In addition, our results illustrate that the construction of the subjective representation, as triggered by subjective connectives such as want, comes at a processing cost. If this representation is already explicitly cued in the first clause of the causal relation, the rest of the subjective relation is processed smoothly. On the basis of these results we proposed that want triggers the representation of a subjective CLAIM-ARGUMENT relation, whereas omdat triggers the representation of an objective CONSEQUENCE-CAUSE relation. Experiment 3 in Chapter 3 provides further evidence that omdat triggers the representation of a CONSEQUENCE-CAUSE relation. In this Conclusion|133 experiment we used both want and omdat in subjective relations that do not make sense with a CONSEQUENCE-CAUSE interpretation such as (4). (4) #Hanneke had haast, omdat ze vier trappen was afgerend om de post te halen. [Hanneke was in a hurry, omdat she four stairs was ran down to the mail get.] Hanneke was in a hurry, because she ran down four stairs to get the mail. We found that in sentences like these, omdat initially leads to faster processing times compared to want. However, at the end of the second clause, at which point it becomes clear that the relation makes no sense, omdat leads to a discourse garden path effect, which is reflected in longer processing times. Taken together, our results provide a quite detailed picture of the role causal connectives play in the dynamic process of discourse comprehension. We found that causal connectives do more than inform the reader that a causal coherence relation needs to be constructed between two pieces of text. On top of that they provide information about the relative degree of subjectivity of that causal relation. On the basis of our results we conclude that the Dutch causal connectives want and omdat instruct the reader to construct either a subjective, or an objective representation of the causal relation. Crucially, this information is put to use immediately when the connectives are processed, as becomes apparent from the immediate processing effects reported throughout this dissertation. This suggests that when readers encounter the connective want, the previous segment is immediately interpreted as a claim or conclusion. These results are in line with the assumption that coherence markers have an immediate influence on the interpretation of the unfolding discourse (e.g. Cozijn Noordman, & Vonk, 2011; Kehler, Kertz, Rohde, & Elman, 2008; Koornneef & Sanders, to appear; Noordman & Vonk, 1997). 6.1.2 Why are subjective causal relations complex? A central question in this study concerns the source of the processing complexity of subjective causal relations. Why should these relations lead to longer processing times compared to objective causal relations? In Chapter 2 we discussed two different explanations for this effect that have been proposed in the literature so far, which we will summarize here. According to Traxler, Sanford, Aked, and Moxey (1997), the processing delay in English subjective compared to objective causal relations is caused by the fact “that it has not been made obvious enough that A [the first clause] is a psychological event” (p.89). They argue that the default interpretation of the first clause of a causal relation is an objective interpretation of the state of affairs in the world. Therefore, the processing effects associated with subjective causal relations surface because “the text 134|Chapter 6 does not signal that a less preferred [subjective] interpretation should be adopted” (p.89). Traxler, Sanford, Aked, and Moxey therefore interpret the processing effect of subjective causal relations in terms of a reanalysis, similar to the garden path effects associated with reduced relatives and reduced complements (Ferreira & Henderson, 1990; Trueswell, Tanenhaus, & Garnsey, 1994; Trueswell, Tanenhaus, & Kello, 1993). Noordman and De Blijzer (2000), on the other hand, argue that the comprehension of causal relations requires a match between the causal relation and a model of the world. Objective causal relations directly reflect real-world causality. Subjective relations, however, are more complex because they less directly reflect real-world causality. These relations involve a line of reasoning on the basis of real-world causality, and the reader has to check the possibility of that underlying causal relation in the world. The results obtained in our experiments shed new light on the complexity of subjective causal relations, and allow us to discard both these explanations. The idea that subjective causal relations are more difficult to process than objective causals because they involve a validation of the underlying causal relation, as Noordman and De Blijzer propose, is incompatible with the early effects of subjectivity that surfaced directly after the subjective connective want. After all, such a checking procedure is expected to play a role towards the end of the relation, because the underlying relation cannot be evaluated before it has become clear what the actual content of that relation is. In Chapters 4 and 5 we further investigated the source of the processing complexity of subjective causal relations. In Chapter 4 we used insights from Mental Spaces Theory (Fauconnier, 1994), which we discuss below, to investigate the online processing of subjective causal relations. The central research question in this chapter was: RQ3 Is the processing complexity of subjective causal relations related to readers’ cognitive processes involved in the setup of the mental space of the thinking subject? In Chapter 5 we started out by testing the reanalysis account, formulated in Traxler, Sanford, Aked, & Moxey (1997). The first research question formulated in this chapter was: RQ4 Is the processing complexity of subjective compared to objective causal relations explained by a reanalysis of S1 as a claim? For sthe ake of argumentation, we will first discuss the latter research question before we will go into research question 3. So far, all preceding studies on subjective causal relations involved CLAIM-ARGUMENT versus Conclusion|135 CONSEQUENCE-CAUSE relations. Therefore, it was impossible to determine whether the subjectivity effect was related to a reanalysis of S1 as a claim or conclusion, or to the inherent complexity of the processing and representation of CLAIM-ARGUMENT relations. The results from Experiment 1 in Chapter 5, however, revealed that the forward subjective connective dus (5a) also leads to an immediate processing slowdown compared to daarom (5b). (5) a. Tim heeft morgen een tentamen. Dus zit hij al uren te studeren. Tim has a test tomorrow. So he has been studying for hours. b. Tim heeft morgen een tentamen. Daarom zit hij al uren te studeren. Tim has a test tomorrow. That is why he has been studying for hours. Similarly to the distinction between want and omdat, speakers of Dutch distinguish between the connectives dus and daarom to express forward subjective and objective causal relations (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, 2005; Verhagen, 2005). Since the conclusion follows the connective in forward subjective causal relations marked by dus, the results from this experiment cannot be explained in terms of a reanalysis of the conclusion triggered by the connective. These results provide evidence against the reanalysis account by Traxler, Sanford, Aked, & Moxey (1997) and suggest that there has to be a different explanation for the complexity of subjective causal relations. Given that the same immediate processing asymmetry between subjective and objective causal connectives arises in forward and backward connectives, we proposed that the cognitive operations involved in the processing and representation of subjective claims or conclusions are inherently complex. The next big question is then: why should the representation of conclusions increase the processing load? We proposed that this effect is related to the representation of the internal world of the thinking subject, be it the speaker, author, or a character in the discourse whose reasoning is presented, to which the utterance relates. Conclusions as part of subjective relations entail speaker involvement (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003); they involve a thinking subject who takes responsibility for uttering the presented conclusion. Therefore the conclusion needs to be interpreted against the background of the mental world of this thinking subject. In Chapters 4 and 5 we have systematically investigated how this process relates to the processing delay in subjective compared to objective causal relations. In Chapter 4 we investigated this issue from a mental spaces perspective in which we focused on research question 3, repeated below. 136|Chapter 6 RQ3 Is the processing complexity of subjective causal relations related to readers’ cognitive processes involved in the setup of the mental space of the thinking subject? Mental Spaces Theory (MST) (Fauconnier, 1994) is a cognitive linguistic framework that has been used to describe the distinction between subjective and objective causal relations (Sanders, Sanders, & Sweetser, 2009, 2012; Verhagen, 2005). The mental space configuration of subjective causal relations has been characterized as more complex than the configuration of objective relations because the latter involves the setup of the mental space of the thinking subject, and interpreting the conclusion within this mental space (Sanders, Sanders, & Sweetser (2009, 2012). In addition, the connectives want and dus, but not omdat or daarom, are assumed to function as space builders that cue the construction of new mental spaces (Verhagen, 2005). In Chapter 4 we investigated whether other space builders in the context preceding the causal relations have the ability to cancel out the processing asymmetry between want and omdat. In order to answer this question, we conducted two eye-tracking experiments in which we manipulated one-paragraph long news texts with embedded subjective (6a) and objective (6b) causal relations marked by want and omdat respectively. (6) a. Het huidige niveau van de studenten is laag want slechts de helft haalt een voldoende voor rekenen en taal. The students' current skill level is low want only half of them pass the maths and language tests. b. Het huidige niveau van de studenten is laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. The students' current skill level is low omdat only half of the teaching hours are dedicated to maths and language. Unlike the Experiments in Chapters 2 and 3, the first clause of both relations in this experiment was exactly the same, including the first text region following the connectives (‘slechts the helft’). We created subjective contexts by adding space builders in the form of evaluative adverbs and adjectives, such as terrible, ridiculously, and luckily, to the title and the context preceding the causal relations. These markers make clear that the text is presented from the author’s perspective. An offline judgment task showed that this manipulation of speaker involvement was successful, as became apparent from judgments about the author’s intentions. In addition, the presence of evaluative markers led to an increase in processing times of subsequent information. These results indicate that readers were sensitive to our manipulation of space builders. However, this manipulation had no influence on the processing asymmetry between want and omdat. We found similar results to those reported in Chapter 3: want led to longer processing Conclusion|137 times compared to omdat. Again, this effect already surfaced at the connectives and at the immediately following text region. These results suggest that the asymmetry between want and omdat is not explained by the necessity of setting up the new mental space of the thinking subject. In Experiment 2 we placed the same (non-sentence modifying) evaluative adverbs within S1 of the causal relations (7). (7) a. Het huidige niveau van de studenten is belachelijk laag want slechts de helft haalt een voldoende voor rekenen en taal. The students' current skill level is ridiculously low want only half of them pass the maths and language tests. b. Het huidige niveau van de studenten is belachelijk laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. The students' current skill level is ridiculously low omdat only half of the teaching hours are dedicated to maths and language. Again, we found no effect of space builders on the processing difference between want versus omdat. As discussed earlier, explicit signals such as John thinks and perhaps, that modify the status of S1 as a whole as a claim or conclusion (8), cancel out the delay in processing times for subjective compared to objective causal relations. The evaluative adverbs and adjectives manipulated in Experiment 2 convey the author’s emotional involvement, yet they do not modify the entire sentence. If used as in (9) they only modify a subpart of S1. Given that these markers do not have the ability to cancel out the processing effect in subjective causal relations, we conclude that this effect must be related to the representation of one of the clauses as a whole as someone’s conclusion or claim. (8) Volgens Jan / Waarschijnlijk [is het huidige niveau van de studenten laag] According to John / Probably [the students' current skill level is low] Het huidige niveau van de studenten is [belachelijk [laag]] The students' current skill level is [ridiculousy [low]] (9) In Chapter 5 we investigated why the representation of such conclusions is resource consuming. Given that claims, or conclusions, are products of reasoning, we hypothesized that the cognitive complexity associated with subjective causality could also be related to this underlying process. Reasoning can be defined as a “simulation of the world fleshed out with our knowledge” (Johnson-Laird, 2010, p.1). It involves the construction of a set of possible mental models compatible with a given situation in the world, on the basis of which a conclusion is derived. It may therefore be the case that, besides the fact that subjective causal relations are linked to the internal world of the thinking subject (they entail speaker involvement), they 138|Chapter 6 also invite the reader, or listener, to follow the underlying steps of reasoning, which increases the processing load. This hypothesis led to the following research question: RQ 5 Can we distinguish between reasoning and speaker involvement in order to explain the inherent processing complexity of subjective compared to objective causal relations? This question has been addressed in Experiments 2 and 3 of Chapter 5. In Experiment 2 we focused on the reasoning aspect of subjective causal relations and compared the processing of the forward subjective connective dus to the inferential evidential adverb blijkbaar. Similar to dus, blijkbaar identifies evidence based upon reasoning (Van der Auwera & Plungian, 1998). Yet, unlike dus, evidentials such as blijkbaar rely on objective evidence in the world, outside the speaker’s beliefs (Giannakidou, 2011; Nuyts, 2001); blijkbaar signals a certain distance from the speaker’s mental world. We found that blijkbaar does not lead to an immediate disadvantage in processing time compared to daarom. These results demonstrate that the processing effect associated with subjective causal relations cannot be explained by the fact that language users have difficulties in processing conclusions derived by reasoning per se. In Experiment 3 we tested whether this effect can be explained by differences in terms of speaker involvement, by including the epistemic modal adverb waarschijnlijk. This adverb provides the speaker’s evaluation of the probability of the following proposition, but at the same time, the speaker does not fully commit him or herself to the truthfulness of that proposition: he or she takes a safe distance (Nuyts, 2004, p.61). We therefore proposed that dus encodes a high degree of speaker involvement whereas blijkbaar encodes a low degree of speaker involvement. Waarschijnlijk takes up an intermediate position (10). (10) Degree of speaker involvement dus > waarschijnlijk > blijkbaar The results from Experiment 3 are consistent with this division along the lines of speaker involvement. We observed longer processing times after waarschijnlijk compared to blijkbaar, yet dus led to even longer processing times. Taken together, we propose that the processing complexity of subjective causal relations can be explained by the notion of speaker involvement (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003). The conclusions and claims presented in subjective causal relations have a special status because they are directly linked to the mental world of the thinking subject – be it the speaker, author, or a third person Conclusion|139 character in the discourse – who is responsible for that particular conclusion. As such, subjective causal relations are more complex than objective relations because language users need to be able to understand that the information in the conclusion is not a description of the outside world, but is part of someone’s view on the world. This is essential information because this view can differ from individual to individual. It is plausible that this information induces several different cognitive operations that could increase the processing load. In section 6.2.3 and 6.2.4 we will further elaborate on these processes. In Chapter 1 of this dissertation we introduced the discussion about the level of representation (Fletcher, 1994; Fletcher & Chrysler, 1990; Graesser, Millis, & Zwaan, 1997; Kintsch, 1998; Zwaan & Radvansky, 1998) at which explicitly marked causal relations are represented. Here, we will briefly consider what our results tell us about the level of representation involved in the representation of subjective causal relations. The distinction between representing the status of information as a description of the world versus someone’s view on the world is not a property of the textual representation of a text. Even though this representation may be triggered by linguistic cues, such as subjective connectives, it differs with respect to the mental picture of the message. As the materials from Chapter 4 in example (6) (page 136) show, claims and objective descriptions can contain exactly the same linguistic content but still receive a different interpretation, that is, objective or subjective. Therefore, we conclude that we are dealing with representations that differ at the level of the situation model rather than the text base. 6.2 Issues for discussion and future research 6.2.1 Cognitive categories reflected in processing The most important result that arises from the various experiments presented in this study is that subjective and objective causal connectives differently affect online discourse processing. We argue that subjective causal connectives such as want and dus trigger the representation of subjective causal relations, whereas objective causal connectives such as omdat and daarom trigger the representation of objective relations. This pattern parallels the semantic profiles of these connectives as put forward in corpus-based studies of their meaning and use (Degand & Pander Maat, 2003; Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003; Sanders & Spooren, 2009; submitted; Stukker, 2005; Verhagen, 2005). Causal relations and connectives have been organized in distinct categories that differ in terms of subjectivity, or speaker involvement. Our results reveal a direct link between these usage patterns and the online 140|Chapter 6 processing of causal connectives. We found no difference between subjective and objective relations when both relations are marked by want (Chapter 2). This difference only appeared when the relations are marked by their prototypical connectives: want in subjective relations, and omdat in objective relations (Chapter 3). In addition, we have shown that the use of the objective connectives daarom and omdat causes processing problems when they are placed in highly subjective relations that are not compatible with the typical relation that these connectives express (Chapter 3 Experiment 3; Chapter 5 Experiment 2). Taken together, these results support the idea that the different categories these causal connectives represent, that of subjective and objective causality, are cognitively ‘real’ (Sanders & Spooren, 2009). A more fundamental question is how these categories could be represented. Some theories distinguish between two separate categories of connectives and relations, that is between relations with a high degree of speaker involvement referred to as subjective, and those with a low degree of speaker involvement referred to as objective (De Smet & Verstraete, 2006; Pander Maat & Sanders 2001; Stukker & Sanders, 2012). Others, however, have argued for a classification in the form of a scale that involves several levels of speaker involvement (Pander Maat & Degand, 2001). Throughout this dissertation we have not committed ourselves to one or the other approach, as it was not the purpose of our study to settle this issue. In Chapter 5 we did propose, as a working hypothesis, a scalar division between the connective dus and the adverbs waarschijnlijk and blijkbaar with respect to the degree of speaker involvement they encode. On the basis of our results there is no way to decide whether subjectivity is in fact to be taken as a scale or not. What is important for our discussion here is that the results presented in this study are compatible with both approaches. Our results demonstrate that the linguistic encoding of speaker involvement comes at a processing cost. Whether or not this varies as a function of the degree of speaker involvement is open for future research. The results obtained throughout this dissertation may have methodological implications for future research focusing on the semanticpragmatic profiles of causal connectives. The traditional methodology used to establish these profiles systematically underestimates the role of causal connectives in the discourse representation. In order to classify the meaning of a causal connective it is first extracted from the text segments that it relates (Sanders, 1997, p.128). Next the degree of subjectivity of the causal relation is established by means of a paraphrase test. Subsequently, the meaning of the connective is determined on the basis of this underlying relation between the two segments. For example, the relation in (11a) with the connective want could be classified as objective because without the connective (11b), the relation can be paraphrased by “the situation in S2 is Conclusion|141 the cause of the situation in S1”. As a result, the meaning of want in this relation would also be classified as objective. (11) a. De straten zijn nat want het regent. The streets are wet want it is raining. b. De straten zijn nat. Het regent. The streets are wet. It is raining. The data presented in the current study suggest that connectives make their own contribution to the discourse representation, irrespective of the propositional content in the two combined segments. If, as our data suggest, connectives influence, or maybe even determine, the degree of subjectivity of the causal relation, the classical methods for determining the semantic profiles of connectives run the risk of misclassifying actual connective meaning. Nevertheless, we understand that this procedure is necessary in order to avoid circular reasoning. The results from the current study are based on the characteristics of Dutch connectives in terms of the amount of subjectivity that they encode. An obvious question that may be addressed in future research concerns the generalizability of the effects presented throughout this study. If subjective and objective causality are indeed two distinct cognitive categories, it follows that similar processing effects should arise in other languages that also have specific linguistic markers for these categories, such as French (e.g. Anscombre & Ducrot, 1983; Le Groupe Lambda- λ, 1975; Zufferey, 2011) German (Pasch, 1983) and Portuguese (Lopes, 2009). However, there may also be languages that do not have specific causal connectives to mark subjective and objective causal relations. Future research may address the question of how these languages signal the degree of subjectivity of causal relations, and how such signals affect online processing. In addition, the effects of coherence markers on text comprehension have been demonstrated to vary across text type and with reader characteristics (McNamara & Kintsch, 1996; McNamara, Kintsch, Songer, & Kintsch, 1996; Meyer, Young, & Bartlett, 1989; Noordman, Vonk, & Kempff, 1992; Kamalski, Lentz, Sanders, & Zwaan, 2008). It may therefore be worthwhile to investigate whether these factors also influence the online processing effects of (subjective) causal connectives. 6.2.2 Subjectivity as speaker involvement As discussed in Chapter 2, there are various ways to characterize the difference between subjective and objective causal relations. Throughout this study we have relied on the notion of speaker involvement as formulated in many other studies (Pander Maat & Degand, 2001; Pander Maat & Sanders, 142|Chapter 6 2000, 2001; Pit, 2003; Stukker, Sanders, & Verhagen, 2009). In these studies, speaker involvement has been described as “…referring to the degree to which the present speaker is implicitly involved in the construal of the relation” (Pander Maat & Degand, 2001, p.214), or “the involvement of the speaker in the interpretation of the relation” (Pander Maat & Sanders, 2001, p.253). Note that these definitions are somewhat misleading because they suggest that speaker involvement only concerns involvement of the speaker. Yet, processing data reveal that third person mental states (John thinks, according to John) have the same ability to cancel out the processing effects in the second clause of subjective causal relations as epistemic modals (perhaps, maybe) do, which implicitly refer to the speaker (Chapter 3; Traxler, Sanford, Aked, & Moxey, 1997). This confirms that speaker involvement concerns any character in a discourse whose reasoning is presented (Sanders, Sanders, & Sweetser, 2009). Indeed, Pander Maat and Degand also refer to involvement of the concluder, who by default is the speaker himself (2001, p.221). In addition, the experimental evidence illustrates that the processing effects of subjectivity cannot be explained in terms of differences in perspective. As discussed in Chapter 2, first person evaluations have been proposed to be more subjective than third person evaluations because their perspective is closer to the communicative “here and now” (Sanders, Sanders, & Sweetser, 2012; Traugott, 1989, 1995). However, the observation that markers of both types of perspective within S1 cancel out the effects of subjectivity suggests that these differences in perspective are not relevant for the processing effects observed in subjective versus objective causal relations. Rather, these processing data stress what these different perspectives have in common: they all involve a thinking subject who is responsible for the causal relation. It is, however, not impossible for there to be differences between such perspectives that could influence the processing of subjective causal relations. For instance, it may be easier to adopt the first person perspective because it is always implicitly available (Sanders, Sanders, & Sweetser, 2009, 2012). It is open for future research to assess the impact of such properties on the processing of subjective causal relations. A second insight provided by the processing data reported in this study, and in Traxler, Sanford, Aked, and Moxey (1997), concerns the level at which subjectivity operates. According to the original definitions, speaker involvement is conceived as a property of relations. However, the experimental evidence on backward causal relations suggests that it is not necessarily the relation between S1 and S2 that causes processing problems, but the link between the proposition comprising the conclusion and the mind of the relevant thinking subject. The effects of subjectivity disappear when the first clause of the subjective causal relation is marked by phrases such as Conclusion|143 perhaps and according to John. These phrases do not build causal relations between clauses, but signal the fact that someone is responsible for the proposition at hand. It may therefore be the case that speaker involvement, as an explanation for the observed processing effects in subjective causal relations, is a property of the clauses that constitute the causal relations rather than the relations themselves. 6.2.3 Complexity from a mental space perspective In Chapter 4 we studied the online processing of subjective causal relations by relying on the theoretical framework of Mental Spaces Theory (MST) (Fauconnier, 1994), which is one way to describe the cognitive processes involved. According to this framework, language users build, and constantly update, a network of mental spaces when they communicate. These mental spaces are conceived as conceptual spaces in which information bound to time, space, and person is represented relative to the here and now. Within MST it is assumed that certain linguistic signals, such as connectives, function as space builders. Crucially, mental space configurations can differ in their overall complexity. Subjective causal relations are assumed to be more complex than objective relations because the latter involve conclusions placed within the mental space of the thinking subject, be it the speaker, author, or a third person character in the discourse (Sanders, Sanders, & Sweetser (2009, 2012). Because MST was not developed as a processing theory, it remains unclear how exactly the processing effects associated with subjective causal relations fit into this theory. Intuitively it makes sense that keeping track of the minds of the speaker and the characters in a discourse is resource consuming. However, this operation may consist of several sub-processes that each may have an individual contribution to the processing complexity. For one thing, the mental spaces that represent the different minds need to be constructed, or set up. Second, language users need to engage in some sort of mapping procedure by which they assign pieces of communicated information to the relevant mental space for interpretation. And third, information bound to specific mental spaces may require a more careful evaluation, against the background of the relevant thinking subject. In addition to these primary processes, there may also be recursive processes involved in the overall representation. Throughout the discourse, the content of the different mental spaces may need to be revised, or updated, whenever new opinions or claims come up. And second, keeping track of everything requires a simultaneous maintenance of the representations of different realities (the real world versus the speaker’s mental world), which obviously draws on executive functions such as working memory. 144|Chapter 6 On the basis of our results we cannot draw clear conclusions about which sub-process is responsible for the observed effects of subjectivity. Nevertheless, the results reported in Chapter 4 do shed some light on this matter. Our data suggest that the immediate processing effects induced by subjective connectives are not necessarily related to the set up of mental space of the thinking subject. Space builders in the form of evaluations in the context preceding the causal relations did not cancel out the processing asymmetry between want and omdat. We therefore tentatively interpreted this immediate effect in terms of the mapping of information onto the specific mental spaces. After all, even if the author ’s perspective is clearly “visible” in a given text, which makes it relatively easy for readers to set up the relevant mental space, this does not mean that all utterances in the text need to be interpreted as claims or conclusion. Even an argumentative text contains objective descriptions of events and situations in the real world. This means that even if a specific mental space has been constructed in the discourse, readers still need to make decisions about how upcoming information is to be interpreted. Future research will have to establish whether the immediate effect of subjective causal connectives is indeed related to such mapping processes. Even though we found no effect of mental space builders on the processing of want versus omdat, we cannot exclude that more restricting contexts can facilitate the mapping of claims onto specific mental spaces. The example in the introduction of Chapter 4, here repeated in (12), makes clear that the intended interpretation of a sentence as a claim can often be easily derived from the communicative context, without local linguistic markers of subjectivity. (12) That referee needs to go look for a new job. Future research may explore whether more restricting communicative settings facilitate the processing of subjective connectives such as want. One way to test this could be by manipulating clear argumentative contexts that bring participants in a more argumentative “mood”, such as heated discussions in a football stadium or between environmental activists. It may be the case that in contexts like these, language users automatically assign all incoming information to the mental space of the relevant thinking subject. The results from Chapter 4 suggest that additional processes involved in the representation of mental spaces could be reflected in online processing. We observed that the presence of mental space builders leads to longer processing times of subsequent text regions compared to neutral contexts, even though these sentences had exactly the same content Conclusion|145 compared to the neutral context. There are two ways to interpret this effect. First, it may result from maintenance of an additional mental space next to the representation of reality. Alternatively, these longer processing times may be a reflection of a more careful evaluation of how to interpret the utterances in a text, that is, as a claim or not. As such, this effect may also be related to mapping processes. On the basis of our data we cannot distinguish between these different sub-processes. In order to verify whether the processing and representation of speaker involvement requires the representation of a thinking subject, future research may include neuroimaging techniques such as FMRI. For example, the repeated name penalty (Gordon, Grosz, & Gilliom, 1993), which arises when a proper name is repeated instead of using a pronoun, has been related specific neural activation patterns associated with the representation of discourse entities (Almor et al., 2007). These results suggest that the repeated name penalty arises because of the increased representational load due to the activation of a new discourse entity. If, as we propose, speaker involvement requires the representation of another person’s mind, it may be the case that this leads to similar activation patterns. 6.2.4 Mental spaces and higher order cognitive processes: Epistemic vigilance Why should language users pay attention to the different mental spaces involved in the representation of claims? One straightforward answer is that claims are not necessarily trustworthy. In fact, the purpose of providing arguments to support claims is to convince others of the truth of those claims. Overt marking of the status of information as a claim, by means of want or dus, may therefore signal that the presented information requires increased attention before it is accepted, a process that can be related to the notion of epistemic vigilance (Sperber et al., 2010). Epistemic vigilance is described as a set of cognitive mechanisms that serve to filter incoming information in order to avoid misinformation, manipulation, and deceit. Crucially, these mechanisms come with a processing cost that is likely to be kept at a bare minimum when the communicated information is not relevant (Sperber et al., 2010, p.363). Epistemic vigilance can be targeted at the source, we make split-second judgments about a person’s trustworthiness when we see a new face (Willis & Todorov, 2006; Ybarra, Chan, & Park, 2001). Or it can be targeted at the content. But clearly these two are also related. As discussed in Chapter 5, the claim in (13) is more credible when it is produced by the weatherman than by an umbrella salesman. (13) I think it will rain today. 146|Chapter 6 Epistemic vigilance, as presented in Sperber et al., has not been fully worked out in terms of a processing model. In fact, the authors point out that many of the assumptions put forward are speculative. Nevertheless, the issues discussed throughout this dissertation seem very compatible with this theoretical proposal, and our results may be used to specify how epistemic vigilance is reflected in online processing. Sperber et al. assume that comprehension involves a tentative stance of trust (Holton, 1994; Origgi, 2005, 2008), which will lead to acceptance if epistemic vigilance does not provide reasons to doubt (Sperber et al., 2010, p.368). It is, however, not clear under what circumstances epistemic vigilance is triggered. Sperber et al. put it very generally by proposing that it is “triggered by the same communicative acts that trigger comprehension” (p.369). The results put forward in our study suggest that specific linguistic cues of subjectivity, such as causal connectives, could function as a trigger for epistemic vigilance. A similar account can be found in Kamalski et al. (2008) who propose that subjective coherence markers trigger resistance to persuasion. The authors argue that the use of subjective coherence markers makes language users realize that the speaker is trying to persuade them. As a result, they stick to their own opinion. However, epistemic vigilance, as described by Sperber et al., differs from this mechanism because it does not necessarily lead to resistance. Epistemic vigilance is not the opposite of trust; it is the opposite of blind trust (p.361). Vigilance, as used in cognitive psychology, refers to “sustained attention”. As such, cues of subjectivity may lead to a more careful evaluation, or interpretation, of information. Whether this immediately leads to a lower level of persuasiveness will depend on many other factors, such as, the source (who is claiming) and the validity of the argument on which it is based. If, however, the information is accepted, it is not excluded that epistemic vigilance results in a stronger representation of that information because the reader, or listener, has been engaged in deeper processing strategies. As such, it is even possible that the use of subjective connectives leads to a higher persuasive power compared to objective connectives. Of course, we can only speculate about such effects. Future research will have to establish whether the processing effects reported in this chapter can be related to these mechanisms, and how they affect the persuasiveness of communication. 6.2.5 Subjectivity and Theory of Mind There is a clear link between the notions of subjectivity, Mental Spaces Theory, and Theory of Mind abilities. Theory of Mind (ToM) is the ability to reason about other people’s mental states. And such metacognitive abilities are a prerequisite for understanding subjective causal relations because these require the representation of other's beliefs and conclusions (Sperber, Conclusion|147 1997). It is a well-known observation that children up to 4 years of age have difficulty processing and representing this type of information because their own knowledge of reality interferes, as becomes apparent from false belief tasks (Baron-Cohen, Leslie, & Frith, 1985; Wimmer & Perner, 1983). However, there is also some experimental evidence that suggests that ToM engaging activities lead to an increased processing load in adults too. Recent experiments with adults reveal that inferring character’s beliefs (true and false beliefs) ad hoc leads to increased reaction times (Back & Apperly, 2010), and there is some evidence to suggest that holding information about other’s beliefs in mind is resource consuming (Apperly, Back, Samson, & France, 2008). These results suggest that even when language users are endowed with ToM abilities, putting these abilities to use may increase the processing load. It remains to be seen whether such effects are related to the processing effects observed in subjective causal relations. Preliminary results by Zufferey (2010) indeed suggest that there is a relation between ToM abilities and the use and comprehension of subjective causal relations. In a corpus study, Zufferey found that French and English autistic children and adolescents, who are known to have limited ToM abilities, do not produce subjective causal relations marked by connectives. Also, in a comprehension study, Zufferey showed that the comprehension of ironic use of puisque in 7-year-old children is moderately correlated with performance on theory of mind tests (p.300). However, because these data are not conclusive, more research is required to establish whether these concepts relate. Interestingly, ToM has been related to the development of epistemic vigilance (Sperber et al.) as well. Around the age of passing the standard false belief test, a validated indicator of children’s ToM abilities, children also become increasingly attentive to the epistemic quality of other people’s beliefs and messages (Sperber et al., 2010, p.373). In addition, they become more selective in their trust, and also more willing and able to manipulate the beliefs of others. This overlap offers insights into the nature and development of ToM abilities. Sperber et al. suggest that ToM, as measured by the false belief test, may actually be the output of epistemic vigilance. The authors propose that children may pay more attention to the relevant aspects of false belief tasks as a result of their increased capacity for epistemic vigilance: “As they become increasingly aware that others may hold false beliefs […] they get better at taking these false beliefs into account when predicting the behavior of others. Their interest is not so much that of an observer, but rather that of a potential victim of misinformation, a potential perpetrator of deception, or a co-operator who prefers knowledgeable partners” (p.373). It remains to be seen whether or not this explanation holds. 148|Chapter 6 Nevertheless, it seems straightforward that the cognitive abilities underlying ToM are also involved in the understanding of subjective causal relations and the representation of mental spaces. How else could we understand other people’s conclusions, if we are unable to distinguish our own beliefs from the beliefs of others? It is open for future research to establish whether and how exactly these concepts relate. It is, however, clear that the processing complexity of subjective causal relations cannot be explained by ToM alone. We still need the linguistic markers of subjectivity that allow us to recognize beliefs and conclusion, and we have to be able to represent and maintain them in a representation such as a mental space configuration. 6.3 Conclusion The results obtained throughout this study all add up to our conclusion that subjective causal connectives and relations require the representation of the mind of the thinking subject, be it the speaker, author, or a third person character in the discourse, who is responsible for the presented information. Crucially, our results suggest that the processes involved in the construction of this representation increase the processing load. Therefore, linguistic devices that trigger this representation, such as the subjective connectives dus and want, will generally induce longer processing times compared to markers that do not, such as omdat and daarom. This is in line with the assumption that causal connectives are processing instructions that help readers construct a coherent discourse representation. We have shown that these instructions go as far as informing the reader about the exact type of causal relation that needs to be constructed, be it subjective or objective. But what could these instructions look like? In Figure 1 we propose a tentative processing model of subjective versus objective causal connectives. Note, that this model does not include syntactic parsing instructions; rather, it describes the instructions about the required discourse interpretation of the causal relation the connectives mark. Conclusion|149 Connective Subjective Direction: Backward - S1 is claim based on S2 or Forward - S2 is claim based on S1 Objective Direction: Backward - S1 is cause of S2 or Forward - S2 is cause of S1 Set up: Find relevant mind & set up mental space Mapping: Assign clause to relevant mental space Reconstruct: Recover underlying inference or add inference to knowledge Evaluate: If access to source & relevant enough Figure 1. A tentative processing model for subjective versus objective causal connectives. Both subjective and objective connectives signal the direction in which they operate. With respect to objective causal relations they specify that S2 functions as the consequence of the situation in S1 (forward relations), or they signal that S2 contains the cause of S1 (backward relations). This cue triggers the construction of the causal relation between the two clauses. Whether or not language users fully understand this relation depends on their ability to recover the underlying causal inferences (if P then Q), in line with the inference function ascribed to causal connectives (Cozijn, Noordman, & Vonk, 2011; Noordman & Vonk, 1997). However, language users may not always able to do so. For example, most readers will not be able to recover the underlying causal inference in (14) because they lack the 150|Chapter 6 relevant background knowledge. That does not mean that they cannot construct the causal relation, they may just not fully understand it. (14) Patrick holds his breath because it is Opposite Day. Readers who know the SpongeBob episode from which this relation is derived will be able to activate the underlying knowledge and generate the necessary inference: Opposite Day means doing exactly the opposite of what you’re used to, therefore Patrick decides to stop breathing. In the absence of such knowledge, Cozijn et al. propose that the presence of the causal connective will invite the reader to derive a causal inference (apparently it is customary to hold your breath on Opposite Day), which they will then add to their world knowledge. The direction of the relation is also relevant for subjective causal connectives. Here, however, the connective signals that S1 functions as a claim or conclusion on the basis of the argument in S2, or it signals that S2 functions as a claim or conclusion on the basis of the argument in S1. Next, the reader needs to find the mind of the thinking subject that is responsible for uttering the claim, and a mental space representing this mind needs to be set up. In line with theories on speaker involvement (Pander Maat & Degand, 2001, p.221) we will assume that, by default, this mind is the speaker’s mind. Subsequently, the claim needs to be mapped onto that mental space. The reason why we are suggesting that the set up of a mental space and the mapping of information onto that space are two distinct processes is that mental spaces can also be set-up by space builders in the preceding discourse. This does not imply, however, that everything that follows is to be interpreted as a (subjective) claim. In this case, subjective connectives still have the mapping function. Similar to objective connectives, subjective causal connectives may invite the reader to derive the underlying causal inference by checking the causal relation against their world knowledge, or by adding the reconstructed inference to their world knowledge. A final piece of information encoded in subjective causal connectives could be a cue to evaluate the information in the claim. The reason why this final step is presented with a dotted line is that language users do not necessarily have to evaluate all the claims they hear. That would in fact be a rather time and energy consuming endeavor, which is unnecessary if the claim is about something that is completely irrelevant to the reader or listener. For example, in (15) the claim “orange is trending” will have a different effect on people who are interested in fashion, compared to those that are not. (15) Orange is trending, because I saw Blake Lively wear an orange dress. Conclusion|151 Fashionistas may run through a number of steps before they will accept the claim as truthful (Is Blake Lively a true fashion icon? Have I seen orange clothing in the fashion magazines?). Fashion phobes, on the other hand, may be able to derive the inference that Blake Lively must be a fashion icon. However, whether or not that justifies the claim “orange is trending” may be of too little interest to them to waste energy on such evaluations in the first place. Note that the model only includes the primary processes triggered by causal connectives. However, we can also identify two recursive processes involved in the representation of subjective causal relations. First, language users need to maintain the representations of the relevant mental spaces in the discourse. In addition, whenever a given space is called into existence, its contents may require revisions, or updates, throughout the discourse whenever new opinions or claims come up. Of course, our model is only a tentative processing model on the basis of the empirical data so far. One thing that remains unclear, for example, is how the evaluation of claims correlates with knowledge of the person who produced it. In order to be able to evaluate a claim, you also need to know something about the source. Is the claim compatible with what I already know about this person’s beliefs? Is this person trustworthy? Does he have a hidden agenda? Is this person knowledgeable? Do we usually share opinions? It is unclear what happens in the absence of such information. It may be the case that in this situation claims stay in some sort of ‘mental space limbo’ and remain unaccepted by the reader. However, it may also be the case that the claim is accepted provided that the argument on which it is based is sound. Conversely, in case of a highly reliable source, we may skip the evaluation process altogether and accept everything that he or she claims as truthful. Future research may focus on how these factors influence the processing of subjective causal connectives and of subjectivity in general. This can only be achieved in a fruitful way by interdisciplinary collaborations between cognitive linguists and text linguists on the one hand, and experimental psycholinguists and social psychologists on the other. Such collaborations should help us get a better understanding of the exact processes involved in discourse processing, which is a crucial part of communication through language.

Verbeteringen in het onderwijs (Context Neutraal) De Nederlandse Pabo-opleidingen gaan vanaf volgend jaar meer aandacht besteden aan het niveau van de studenten. In plaats van 8 uur wordt er dan 14 uur per week uitgetrokken voor reken- en taalvakken. II. Pabo moet echt beter (Context Subjectief) De Nederlandse Pabo-opleidingen gaan vanaf volgend jaar eindelijk meer aandacht besteden aan het niveau van de studenten. In plaats van 8 uur wordt er dan maar liefst 14 uur per week uitgetrokken voor reken- en taalvakken. Target: Het huidige niveau van de studenten is laag a. want / slechts de helft / haalt een voldoende / voor rekenen / en taal. b. omdat / slechts de helft / van de onderwijsuren / wordt besteed / aan rekenen en taal. Afsluiting: De minister van Onderwijs pleit voor strengere toelatingseisen en meer toetsingsmomenten in een schooljaar. 2. I. Voedingscentrum luidt de noodklok Minister Klink van volksgezondheid heeft een onderzoek ingesteld naar de gezondheid van vegetariërs en vleeseters. Eerder deze maand luidde het voedingscentrum de noodklok over vegetarisme bij kinderen. II. Voedingscentrum moet vegetariërs aanpakken Minister Klink van volksgezondheid heeft eindelijk een degelijk onderzoek ingesteld naar de gezondheid van vegetariërs en vleeseters. Eerder deze maand luidde het voedingscentrum gelukkig al de noodklok over vegetarisme bij kinderen. Kinderen die geen vlees eten zijn niet gezond a. want / deze kwetsbare groep / heeft vaak last / van bloedarmoede / en andere kwalen. b. omdat / deze kwetsbare groep / ongemerkt / te weinig / vitaminen binnen krijgt. Het voedingscentrum adviseert alle vegetariërs om extra b12 bij te slikken. 3. I. Nieuwe aanpak studentenhuisvesting De Tweede Kamer houdt vanmiddag een debat over huisvesting voor studenten en starters. Vooral de gemeentes Nijmegen en Amsterdam staan hoog op de agenda. II. Studentenhuisvesting kan veel beter De Tweede Kamer houdt vanmiddag eindelijk het broodnodige debat over huisvesting voor studenten en starters. Vooral in de gemeentes Nijmegen en Amsterdam moet nu echt wat aan de situatie veranderen. De gemeente Nijmegen doet weinig aan betaalbare huisvesting in de stad a. want / veel woningzoekenden / moeten uitwijken / naar buurgemeenten / Lent en Elst. 176|Appendix 3 b. omdat / veel woningzoekenden / ook in omringende / gemeenten / willen wonen. Minister van der Laan zal een voorstel doen om dit probleem zo snel mogelijk aan te pakken. 4. I. Ontwikkelingsbeleid onder de loep Uit een onderzoek van de Universiteit Twente is gebleken dat de ontwikkelingshulp, die Europa de afgelopen decennia aan Afrika heeft geboden, negatieve effecten heeft.

Ontwikkelingsbeleid moet anders Uit een opzienbarend onderzoek van de Universiteit Twente is gebleken dat de goedbedoelde ontwikkelingshulp, die Europa de afgelopen decennia aan Afrika heeft geboden, behoorlijk wat negatieve effecten heeft. Deze uitkomst is in strijd met eerdere twijfelachtige conclusies van de EU. Ontwikkelingshulp belemmert Afrika a. want / de bevolking / is met de jaren / alleen maar armer / geworden. b. omdat / de bevolking / hierdoor niet leert / om op eigen / benen te staan. Volgens de onderzoekers is het veel beter om te investeren in educatie zodat de Afrikanen meer kansen krijgen om een vak te leren. 5. I. Meer stallingen Arnhem centraal De gemeente Arnhem werkt sinds 2008 aan een grootschalige verbouwing van het centraal station. Een probleem dat hiermee wordt aangepakt is de beperkte parkeermogelijkheid voor fietsers. II.

Een probleem dat hiermee gelukkig wordt aangepakt is de beperkte parkeermogelijkheid voor fietsers. Er zijn nu te weinig fietsenstallingen a. want / de straten / rond het station / staan vol / met slordig geparkeerde fietsen. b. omdat / de straten / rond het station / te smal zijn / voor extra fietsenstallingen. Uiterlijk 2015 zal het probleem opgelost worden. 6. I. Herziening basisbeurs Minister Plasterk heeft aangekondigd de basisbeurs van de studiefinanciering af te willen schaffen. De landelijke studentenbond is bezorgd over de financiële situatie van toekomstige studenten. II. Herziening basisbeurs is nekslag Minister Plasterk kwam vorige maand met de schokkende aankondiging de basisbeurs van de studiefinanciering af te willen schaffen. De landelijke studentenbond is hierdoor natuurlijk zeer bezorgd over de financiële situatie van studenten. De meesten kunnen nu al niet rondkomen van 246 euro basisbeurs a. want / studenten / lenen jaarlijks / gemiddeld duizenden / euro’s bij. Appendix 3|177 b. omdat / studenten / gemiddeld 300 euro / moeten betalen / voor een kamer. Door de nieuwe wetgeving zullen er naar verwachting minder jongeren aan een studie gaan beginnen, uit angst voor een te hoge studieschuld. 7. I. Growshops extra aandacht politie De politie in Den Helder gaat dit jaar extra letten op het doen en laten van growshops. Dat zijn winkels waar benodigdheden voor de teelt van hennep verkocht worden. II. Growshops gelukkig extra aandacht politie De politie in Den Helder gaat dit jaar eindelijk eens extra letten op het doen en laten van growshops. Dat zijn dubieuze winkels waar benodigdheden voor de teelt van hennep zomaar verkocht mogen worden. Growshops zorgen voor problemen a. want / over het algemeen / kampen de wijken / waarin ze staan / met allerlei vormen van criminaliteit. b. omdat / over het algemeen / veel crimineel / publiek op de / winkels afkomt. Begin volgend jaar zal er een evaluatierapport verschijnen over de nieuwe aanpak. 8. I.

Astma Fonds verdient een medaille In aanloop naar de gemeenteraadsverkiezingen voert het Astma Fonds een fantastische campagne met acties in Amsterdam, Den Haag en Arnhem. Speerpunt van de campagne is het overtuigen van politici om de luchtkwaliteit in de steden eindelijk eens goed aan te pakken. De stadslucht is ernstig vervuild a. want / jaarlijks / worden er steeds / meer mensen / ziek van. b. omdat / jaarlijks / meer CO2 door / uitlaatgassen / wordt uitgestoten. Van 22 tot en met 25 februari organiseert de stichting publieke debatten om het bewustzijn onder de bevolking te vergroten. 9. I. Minder reizigers NS Uit de kwartaalcijfers van de NS is gebleken dat de winst in het eerste kwartaal van 2010 is gedaald. De afname wordt in verband gebracht met de prijsstijgingen die in 2009 zijn doorgevoerd. II. Mensen hebben natuurlijk genoeg van de NS Uit de kwartaalcijfers van de NS is gebleken dat de winst in het eerste kwartaal van 2010 verschrikkelijk is gedaald. De afname wordt natuurlijk in verband gebracht met de belachelijke prijsstijgingen die in 2009 zijn doorgevoerd. Reizen met de trein is minder populair geworden a. want / veel reizigers / hebben dit jaar / hun abonnement / opgezegd. 178|Appendix 3 b. omdat / veel reizigers / het te duur vinden / om met de / trein te reizen. Reizigersorganisatie Rover heeft laten weten dat de afname mogelijk ook ligt aan een verminderd vertrouwen in de NS. 10. I. Melkboeren protesteren Melkboeren zijn gisteren in tien lidstaten van de Europese Unie de straat op gegaan om te protesteren tegen de dalende melkprijs. De boeren zullen pas weer melk aanleveren als er nieuwe afspraken over de melkprijs zijn gemaakt. II. Melkboeren moeten wel protesteren Melkboeren zijn gisteren in tien lidstaten van de Europese Unie de straat op gegaan om eens flink te protesteren tegen de zorgwekkend dalende melkprijs. De boeren zullen pas weer melk aanleveren als er fatsoenlijke afspraken over de melkprijs zijn gemaakt. De huidige prijs is laag a. want / in de afgelopen / 6 maanden zijn veel / boeren failliet / gegaan. b. omdat / in de afgelopen / 6 maanden in alle / lidstaten de vraag / naar melk is gedaald. Vandaag zal een delegatie van de EMB in Brussel een onderhoud hebben met eurocommissaris Mariann Fischer Boel van Landbouw. 11. I. Instellen TomTom strafbaar De politie heeft aangekondigd dat het instellen van een TomTom tijdens het rijden strafbaar wordt gesteld. Hiermee reageert de landelijke Politie op het verzoek van de ANWB om strengere regels op te stellen. II. Instellen TomTom nu dan toch strafbaar De politie heeft aangekondigd dat het instellen van een TomTom tijdens het rijden eindelijk strafbaar wordt gesteld. Hiermee reageert de landelijke Politie op het begrijpelijke verzoek van de ANWB om eindelijk eens strengere regels op te stellen. Het probleem wordt nu groots aangepakt a. want / dit jaar / is er 1 miljoen euro / uitgetrokken voor een / voorlichtingscampagne. b. omdat / dit jaar / al honderden mensen / een ongeluk hebben / veroorzaakt tijdens het instellen van de TomTom. De politie maakt zich ook zorgen over de extra mogelijkheden van de apparaatjes, zoals televisie kijken. 12. I. WHO waarschuwt voor homeopathie De Wereldgezondheidsorganisatie WHO waarschuwt mensen voor homeopathische middelen.

WHO waarschuwt eindelijk voor homeopathie De Wereldgezondheidsorganisatie WHO waarschuwt eindelijk voor homeopathische middelen. De WHO reageerde terecht op de schokkende resultaten van een onderzoek van het Health Network waaruit blijkt dat homeopathische middelen levensgevaarlijk kunnen zijn. Appendix 3|179 Homeopathie is slecht voor de volksgezondheid a. want / veel patiënten / krijgen te maken / met ernstige / bijwerkingen. b. omdat / veel patiënten / de door reguliere / artsen / voorgeschreven medicijnen laten staan. Vanavond houdt de Tweede Kamer een spoeddebat over de situatie. 13. I. Bioscopen weigeren Frankenweenie Een groot aantal Nederlandse bioscopen gaat Frankenweenie, de nieuwe Disneyfilm van regisseur Tim Burton, niet vertonen. Dat is het antwoord van de Nederlandse Vereniging van Bioscoopexploitanten (NVB) op het besluit van Disney om de film al binnen 3 maanden op dvd uit te brengen. II. Disney ligt weer eens dwars De meeste Nederlandse bioscopen gaan Frankenweenie, de spectaculaire nieuwe film van regisseur Tim Burton en Disney, niet vertonen. Dat is het terechte antwoord van de Nederlandse Vereniging van Bioscoopexploitanten op het lachwekkende besluit van Disney om de film al binnen 3 maanden op dvd uit te brengen. Disney heeft zich in de nesten gewerkt a. want / de filmmaatschappij / wordt door meerdere / landen / geboycot. b. omdat / de filmmaatschappij / zich niet aan / de internationale / afspraken houdt. Volgende week gaan alle partijen nogmaals in overleg om tot een compromis te komen. 14. I. Problemen door OV chipkaart De invoering van de OV-chipkaart heeft geleid tot ontevredenheid onder reizigers. Dit blijkt uit een onderzoek van de provincie Zuid-Holland. II. OV chipkaart is een drama De invoering van de zogenaamd handige OV-chipkaart heeft geleid tot grote ontevredenheid onder reizigers. Dit blijkt uit een confronterend onderzoek van de provincie Zuid-Holland. De OV chipkaart is geen succes a. want / veel mensen / zijn weer meer / met de auto gaan / reizen. b. omdat / veel mensen / niet goed weten / hoe ze de kaart / moeten gebruiken. Minister Peijs van Verkeer heeft toegegeven dat er nog veel verbeterd moet worden aan het nieuwe systeem. 15. I. Documentairemaker BBC opgepakt Documentairemaker Ray Grosling (70) van de BBC is opgepakt nadat hij had toegegeven dat hij jaren geleden zijn ongeneeslijk zieke partner had geholpen bij zelfdoding.

Ray Grossling is een held De sympathieke documentairemaker Ray Grosling van de BBC is opgepakt nadat hij had toegegeven dat hij jaren geleden zijn ongeneeslijk zieke partner had geholpen bij 180|Appendix 3 zelfdoding. De Britse omroep heeft gelukkig bekend gemaakt alles te zullen doen om een gevangenisstraf te voorkomen. Grosling is niet bang voor strafrechtelijke vervolging a. want / de documentairemaker / bekende zijn daad / op nationale / televisie. b. omdat / de documentairemaker / vindt dat / zijn daad / gerechtvaardigd is. De Britse politie is een onderzoek gestart naar de toedracht van de moord. 16. I. Kabinet is gevallen Het kabinet-Balkenende is zaterdagmorgen ten val gekomen. De urenlange vergaderingen over de parlementscrisis konden het vertrouwen in de minister-president niet verbeteren. II. Weer een Kabinet gevallen Er is weer een kabinet-Balkenende gevallen. De urenlange vergaderingen over de parlementscrisis konden het vertrouwen in de minister-president blijkbaar niet verbeteren. De populariteit van Balkenende is afgenomen a. want / het CDA / is flink / gedaald in de / peilingen. b. omdat / het CDA / zich niet / aan het regeerakkoord / heeft gehouden. Het is nog onduidelijk wanneer de nieuwe verkiezingen zullen worden gehouden. 17. I. ABN deelt bonussen uit ABN-AMRO betaalt zijn werknemers over 2009 in totaal 520 miljoen euro aan bonussen.

De Tweede Kamer heeft de Minister van Financiën gelukkig opgeroepen om maatregelen te nemen tegen het belachelijke beleid. ABN-AMRO heeft slecht gepresteerd a. want / de bank / heeft subsidie / nodig om / te kunnen bestaan. b. omdat / de bank / te lijden heeft / onder de / crisis. Vakbond CNV Dienstenbond liet weten een dubbel gevoel te hebben bij het beloningsvoorstel. 18. I.

De hertellingen gaan in de openbaarheid plaatsvinden en kosten de gemeente naar schatting enkele tonnen. 21. I.

De invloed van subjectieve versus objectieve causale connectieven op de verwerking van discourse Wanneer taalgebruikers met elkaar communiceren speelt het vermogen om een mentale representatie van de informatie te maken een belangrijke rol. Hierbij is het niet genoeg om alleen de betekenis van de losse onderdelen (zinnen of deelzinnen) van de discourse te begrijpen, het is van essentieel belang dat we ook in staat zijn deze delen te verbinden door er relaties tussen te leggen. Dit soort relaties worden coherentierelaties (cf. Hobbs 1979; Sanders, Spooren & Noordman, 1992; Kehler, 2002) genoemd. Voorbeelden van coherentierelaties zijn additieve (1a), contrastieve (1b) en causale relaties (1c). Deze relaties kunnen expliciet worden gemaakt door middel van talige signalen zoals connectieven (en, maar, dus) en signaalzinnen (om die reden, dat is waarom). (1) a. Mijn fiets is gestolen en ik heb net mijn telefoon in de wc laten vallen. b. Hij was niet knap maar ik ben toch maar met hem uit gegaan. c. Mijn zusje heeft mijn schoenen verpest dus heeft ze nu een groot probleem. Coherentierelaties en hun talige markeerders spelen een grote rol in het onderzoek naar het begrip en de verwerking van discourse. Diverse studies hebben aangetoond dat de aanwezigheid van coherentiemarkeerders, zoals connectieven, in een tekst een positieve invloed heeft op de constructie van een coherente discourse. Deze signalen maken de coherentierelaties tussen zinsdelen expliciet, en deze informatie leidt tot een snellere verwerking van de informatie die volgt na het connectief (Cozijn, Noordman, & Vonk, 2011; Haberlandt, 1982; Kamalski, Sanders, Lentz, & Zwaan, 2008; Millis, Golding, & Barker, 1995; Millis & Just, 1994; Noordman & Vonk, 1997; Sanders & Noordman, 2000), en tot een betere tekstrepresentatie (Degand & Sanders, 2002; Hyönä & Lorch, 2004; Loman & Mayer, 1983; Lorch & Lorch, 1986; McNamara, Kintsch, Songer, & Kintsch, 1996; Meyer, Brandt, & Bluth, 1980; Millis & Just, 1994; Sanders, Land, & Mulder, 2007). Om die reden wordt verondersteld dat connectieven fungeren als instructies voor verwerking (e.g. Britton, 1994; Gernsbacher, 1997; Murray, 1995; Sanders & Spooren, 2007). Het doel van dit proefschrift is meer inzicht te verkrijgen in het soort informatie dat in deze instructies is vastgelegd, en hoe deze informatie de online verwerking van discourse beïnvloedt. De nadruk ligt hierbij op causale connectieven en de vraag of deze signalen ook informatie verschaffen over het type causale relatie dat ze markeren. 206|Samenvatting Subjectieve en objectieve causale relaties In de literatuur worden er grofweg twee soorten causale relaties onderscheiden: subjectieve en objectieve causale relaties (Degand & Pander Maat, 2003; Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001). Een causale relatie is objectief wanneer er sprake van een oorzaakgevolg relatie in de werkelijke wereld (2a). In subjectieve relaties (2b) bestaat de causaliteit niet in de werkelijke wereld, maar in het hoofd van de spreker. Deze trekt een conclusie, of beweert iets, op basis van een bepaalde situatie of gebeurtenis. (2) a. Mijn buurman heeft zijn arm gebroken omdat hij is uitgegleden over een bananenschil. b. Mijn buurman is een sukkel want hij is uitgegleden over een bananenschil. Er zijn twee redenen waarom het relevant is om dit onderscheid in relatie tot causale connectieven te bestuderen. Ten eerste zijn er veel talen waarin causale connectieven zich specialiseren in subjectieve of objectieve causale relaties (Stukker & Sanders, 2012). Ten tweede wordt er verondersteld dat subjectieve causale relaties complexer zijn dan objectieve relaties (Sanders, Spooren, & Noordman, 1992). Deze veronderstelling wordt ondersteund door resultaten van studies naar taalverwerving en psycholinguïstische experimenten. Subjectieve causale relaties komen later voor in de kindertaal van zowel Nederlandse als Engelse kinderen. (EversVermeul & Sanders, 2011; Van Veen, 2011). Daarnaast laten leesexperimenten zien dat subjectieve causale relaties langzamer worden verwerkt dan objectieve relaties (Noordman & De Blijzer, 2000; Traxler, Bybee, & Pickering; Traxler, Sanford, Aked & Moxey, 1997). Traxler, Sanford, Aked en Moxey (1997) hebben bijvoorbeeld met een leesexperiment (self-paced reading) aangetoond dat subjectieve relaties zoals (4b) leiden tot langere leestijden van de gehele zin die volgt na het connectief because, vergeleken met objectieve relaties (3a). Leestijden wordt over het algemeen geïnterpreteerd als een reflectie van de hoeveelheid cognitieve energie die het de lezer kost om een tekst te lezen en te begrijpen: hoe langer de leestijden, hoe moeilijker de tekst is. (3) a.Rick almost died from shock because a poisonous snake bit him on the leg. Rick overleed bijna aan een shock ‘because’ een giftige slang hem in zijn been heeft gebeten b.Rick was walking in a remote area because a poisonous snake bit him on the leg. Rick was in een afgelegen gebied aan het wandelen ‘because’ een giftige slang hem in zijn been heeft gebeten. Samenvatting|207 Met nagenoeg hetzelfde testmateriaal lieten Traxler, Bybee, en Pickering (1997) in een oogbewegingsexperiment zien dat dit effect gecentreerd is rondom het werkwoord, op het tekstsegment bit him in (4b). Zoals te zien is in voorbeeld (3) worden in het Engels zowel subjectieve als objectieve causale relaties uitgedrukt met connectief because. Dit connectief kan daarom beschouwd worden als een algemeen connectief dat geen informatie verschaft over de mate van subjectiviteit van de causale relatie (zie bijvoorbeeld Couper- Kuhlen, 1996; Ford, 1993; Knott & Dale, 1994; Knott & Sanders, 1998; Sweetser, 1990). In het Nederlands zijn er echter connectieven die gespecialiseerd zijn in het uitdrukken van een subjectieve dan wel objectieve relatie. Uit corpusonderzoek is gebleken dat bij achterwaartse causale relaties zoals in (3) (waarin het effect voorafgaat aan de oorzaak in de tekst) het connectief want een prototypische markeerder is voor subjectieve relaties, terwijl omdat een prototypische markeerder is van objectieve relaties (Degand & Pander Maat, 2003; Pit, 2003; Sanders & Spooren, 2009, submitted; Verhagen, 2005). Bij voorwaartse causale relaties, waarin de oorzaak voorafgaat aan het gevolg, is het connectief dus een prototypische markeerder van subjectieve relaties, en is daarom prototypische voor objectieve relaties (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Stukker, 2005; Verhagen, 2005). In dit proefschrift is onderzocht of dit verschil tussen subjectieve en objectieve causale connectieven ook van invloed is op de verwerking van causale relaties. Causale connectieven als instructies voor verwerking In de hierboven beschreven experimenten van Traxler, Sanford, Aked, en Moxey (1997) en Traxler, Bybee, en Pickering (1997) stond de subjectiviteit van de causale relaties centraal. In Hoofdstuk 2 wordt verslag gedaan van een oogbewegingsexperiment waarin voor het eerst werd onderzocht of subjectiviteit ook een rol speelt in de verwerking van causale connectieven. Omdat because altijd vertaald kan worden met want, maar niet altijd met omdat, hebben we de volgende onderzoeksvraag geformuleerd: RQ1 Geeft want dezelfde verwerkingsinstructies als because? Om deze vraag te beantwoorden werd een Nederlandse versie van het testmateriaal van Traxler, Bybee en Pickering (1997) gebruikt. Zowel de objectieve (4a) als de subjectieve (4b) relaties werden gemarkeerd door het connectief want. (4) a. Hanneke was buiten adem, want ze was vier trappen afgerend om de post te halen. b. Hanneke had haast, want ze was vier trappen afgerend om de post te halen. 208|Samenvatting In het originele Engelse experiment werd het verwerkingsverschil tussen subjectieve en objectieve relaties gevonden op de tekstregio met het hoofdwerkwoord. De positie van dit effect komt overeen met de assumptie dat het connectief because zelf geen informatie verstrek over de aard van de causale relaties (subjectief of objectief). De lezer moet dit zelf herleiden aan de hand van de inhoud van de twee zinnen, wat het relatief late effect verklaart. De resultaten van het Nederlandse experiment lieten echter geen verwerkingsverschil tussen subjectieve en objectieve causale relaties zien. Een mogelijke verklaring voor deze uitkomst is dat want (als prototypische markeerder van subjectieve relaties) de lezer mogelijk instrueert om een subjectieve relatie te construeren, ook al is de relatie tussen de twee tekstsegmenten zonder connectief objectief (zoals 5a). Hierdoor behandelt de lezer de eerste zin (ook wel S1 genoemd) van (5a) mogelijk als een bewering (die zou worden gevolgd door een argument) in plaats van als een gevolg (dat zou worden gevolgd door een oorzaak). In Hoofdstuk 3 werd deze verklaring verder onderzocht door de volgende onderzoeksvraag te testen: RQ2 Is het onderscheid tussen subjectieve en objectieve causale connectieven dat voortkomt uit corpusonderzoek naar de semantisch-pragmatische eigenschappen van connectieven relevant in online verwerking? Als dat zo is, op welk moment tijdens het leesproces treedt het dan op? In Experiment 1 van Hoofdstuk 3 hebben we exact hetzelfde materiaal gebruikt als in Hoofdstuk 2, met als enige verschil dat het connectief omdat gebruikt werd om de objectieve relaties uit te drukken, zie (5). (5) Hanneke was buiten adem, omdat ze vier trappen was afgerend om de post te halen. Ditmaal repliceerden we de resultaten van het Engelse experiment: subjectieve relaties (met want) leidden tot langere leestijden dan objectieve relaties (met omdat). Opmerkelijker was de bevinding dat het vertragingseffect in het Nederlands zich veel eerder voordoet dan in het Engels, namelijk direct na het connectief want. Op dit moment in de zin heeft de lezer nog lang niet genoeg inhoud verwerkt om te bepalen of de relatie subjectief of objectief is. Dit betekent dat het verschil in verwerkingstijd wel te maken moet hebben met de semantische en pragmatische eigenschappen van de twee connectieven. De resultaten van Experiment 2 bevestigden dat het effect in Experiment 1 gerelateerd is aan het verschil tussen want en omdat in termen van subjectiviteit. Uit dit experiment bleek dat het vertragingseffect Samenvatting|209 na het connectief want verdwijnt wanneer de lezer al in de voorafgaande zin weet dat deze zin geen feit, maar een bewering of conclusie is, door mentale predicaten zoals “volgens Peter” toe te voegen (6). (6) Volgens Peter had Hanneke haast, want ze was vier trappen afgerend om de post te halen. Deze uitkomst repliceert eerder onderzoek in het Engels (Traxler, Sandford, Aked & Moxey, 1997), en laat zien dat de complexiteit van dit type subjectieve relaties in zowel het Engels als het Nederlands te maken heeft met de representatie van S1 als iemands redenering, of bewering, in plaats van een beschrijving van de werkelijke wereld. De resultaten van Experiment 2 sluiten een alternatieve verklaring voor het verwerkingsverschil tussen want en omdat in termen van syntactische verschillen (subordinerend versus coördinerend) uit. De toevoeging van “volgens Peter” aan S1 verandert niets aan deze eigenschappen, maar het doet het verwerkingsverschil tussen de twee connectieven wèl verdwijnen. Daarnaast suggereren onze resultaten dat de constructie van een subjectieve representatie, opgeroepen door subjectieve connectieven zoals want, extra cognitieve energie kost. Als deze representatie al in S1, dus vóórdat de lezer want heeft gelezen, wordt opgeroepen, dan kan de rest van de subjectieve relatie zonder problemen worden verwerkt. Op basis van deze resultaten kwamen we tot de hypothese dat want werkt als een trigger voor de representatie van een subjectieve bewering– argument relatie, terwijl omdat de representatie van een objectieve gevolgoorzaak relatie activeert. Deze laatste hypothese werd ondersteund door de resultaten van Experiment 3. In dit experiment hebben we gebruik gemaakt van subjectieve causale relaties die onzinnig zijn met een gevolg-oorzaak interpretatie (7), en deze met zowel want als omdat aangeboden. (7) ?Hanneke had haast, omdat ze vier trappen was afgerend om de post te halen. De resultaten waren als volgt: omdat zorgde in relaties zoals (7) in eerste instantie voor een snellere verwerking ten opzichte van want. Echter, aan het einde van de tweede zin, wanneer het voor de lezer duidelijk wordt dat de relatie met omdat nergens op slaat, zorgde omdat juist voor langere leestijden ten opzichte van want. De resultaten van deze eerste experimenten laten zien dat causale connectieven veel meer doen dan de lezer informeren dat er een causaal verband bestaat tussen twee tekstdelen. Deze signalen geven ook informatie over de mate van subjectiviteit van die relatie. Op basis van onze resultaten concluderen we dat de Nederlandse connectieven want en omdat fungeren 210|Samenvatting als instructies aan de lezer (of luisteraar) om respectievelijk een subjectieve of objectieve causale relatie te construeren. Deze informatie wordt direct gebruikt wanneer de connectieven zijn verwerkt, wat blijkt uit de effecten die zich onmiddellijk na de connectieven voordoen. Dit zou betekenen dat wanneer taalgebruikers het connectief want tegenkomen in een tekst, ze de voorafgaande zin gaan interpreteren als bewering of conclusie. Deze resultaten zijn verenigbaar met de veronderstelling dat coherentiemarkeerders de interpretatie van de te verwerken informatie direct beïnvloeden (e.g. Cozijn, Noordman & Vonk, 2011; Koornneef & Sanders, te verschijnen; Kehler, Kertz, Rohde & Elman, 2008; Noordman & Vonk, 1997). Waarom zijn subjectieve causale relaties complex? Een centrale vraag in dit proefschrift betreft de oorzaak van de verwerkingscomplexiteit van subjectieve causale relaties. Waarom zorgen deze relaties voor langere leestijden vergeleken met objectieve relaties? In Hoofdstuk 2 hebben we twee theoretische verklaringen voor dit verschijnsel besproken die tot nu toe in de literatuur zijn aangedragen. Volgens Traxler, Sanford, Aked, en Moxey (1997) wordt het vertragingseffect in subjectieve vergeleken met objectieve causale relaties veroorzaakt door het feit dat “het niet duidelijk genoeg is gemaakt dat A [de eerste zin] een mentale gebeurtenis is” (p.89). Volgens de auteurs is de standaard interpretatie van zo’n eerste zin altijd een objectieve interpretatie van een situatie in de werkelijke wereld. De verwerkingseffecten in subjectieve relaties doen zich dan ook voor omdat “de tekst niet duidelijk maakt dat er een interpretatie moet worden toegekend die niet de voorkeur heeft” (p.89). Traxler, Sanford, Aked en Moxey interpreteren deze effecten daarom in termen van een heranalyse, vergelijkbaar met de bekende garden path effecten zoals die zich voordoen in relatieve bijzinnen (Trueswell, Tanenhaus & Garnsey, 1994; Trueswell, Tanenhaus & Kello, 1993). Noordman en De Blijzer (2000) hebben een andere kijk op de zaak en stellen dat er aan het begrip van causale relaties een vergelijking tussen de desbetreffende relatie en een model van de wereld ten grondslag ligt. Het begrip van objectieve relaties is relatief makkelijk doordat oorzaak en gevolg in objectieve causale relaties overeenkomen met causaliteit in de werkelijke wereld. Subjectieve causale relaties daarentegen zijn complexer omdat deze relaties een minder directe weerspiegeling zijn van causaliteit in de werkelijke wereld. Subjectieve relaties bevatten een redenering op basis van een situatie of gebeurtenis in de wereld, en de lezer moet eerst checken of de onderliggende oorzaak-gevolg relatie klopt. Samenvatting|211 De resultaten van onze experimenten werpen een nieuw licht op de complexiteit van subjectieve causale relaties en maken het mogelijk om beide theorieën te verwerpen. Het idee dat subjectieve causale relaties moelijker zijn omdat de onderliggende causale relatie eerst gevalideerd moet worden, zoals Noordman en De Blijzer postuleren, is niet verenigbaar met de zeer vroege effecten van subjectiviteit die onmiddellijk na het connectief want verschijnen. Immers, zo’n valideringsprocedure zou alleen een rol kunnen spelen richting het eind van de causale relatie, aangezien de relatie onmogelijk kan worden gevalideerd voordat het duidelijk is wat de inhoud van die relatie is. Verderop in deze samenvatting zullen we ingaan op de heranalyseverklaring van Traxler, Sanford, Aked en Moxey (1997). In Hoofdstuk 4 en 5 werd de complexiteit van subjectieve causale relaties nader onderzocht. In Hoofdstuk 4 hebben we gebruik gemaakt van inzichten uit de Mental Spaces Theory (Fauconnier, 1994), die hieronder wordt besproken, om de online verwerking van subjectieve causale relaties te bestuderen. De hoofdvraag in dit hoofdstuk was: RQ3 Wordt de verwerkingscomplexiteit van subjectieve causale relaties bepaald door de cognitieve processen tijdens het lezen die te maken hebben met de constructie van de mental space van de spreker of auteur als denkende instantie? In Hoofdstuk 5 begonnen we met het toetsen van de heranalyseverklaring, geformuleerd in Traxler, Sanford, Aked, en Moxey (1997). De eerste onderzoeksvraag die in dit hoofdstuk aan de orde kwam is: RQ4 Is de verwerkingscomplexiteit van subjectieve causale relaties vergeleken met objectieve causale relaties te verklaren door een heranalyse van S1 als een bewering? In deze samenvatting zal ik eerst onderzoeksvraag 4 bespreken voordat we overgaan naar onderzoeksvraag 3. Tot nu toe hebben alle voorgaande studies naar de verwerking van subjectieve causale relaties gekeken naar de verwerking van (achterwaartse) bewering-argument relaties ten opzichte van gevolg-oorzaak relaties. Daardoor was het onmogelijk om te bepalen of het effect van subjectiviteit te wijten was aan een heranalyse van S1 als een bewering of conclusie, of aan de inherente complexiteit van de verwerking en representatie van bewering-argument relaties. In Experiment 1 van Hoofdstuk 5 hebben we daarom gekeken naar voorwaartse causale relaties gemarkeerd door het subjectieve connectief dus (8a) en het objectieve connectief daarom (8b). 212|Samenvatting (8) a. Tim heeft morgen een tentamen. Dus zit hij al uren te studeren. b. Tim heeft morgen een tentamen. Daarom zit hij al uren te studeren. De resultaten lieten zien dat het connectief dus ook tot een onmiddellijke vertraging in het leesproces leidt ten opzichte van daarom. Aangezien in voorwaartse subjectieve relaties met dus de conclusie pas na het connectief komt, kan het resultaat van dit experiment niet verklaard worden door een heranalyse van de conclusie die door het connectief wordt opgeroepen. Deze resultaten kunnen worden gebruikt als evidentie tegen de heranalyseverklaring van Traxler, Sanford, Aked, en Moxey (1997) en suggereren dat er een andere verklaring moet zijn voor de verwerkingscomplexiteit van subjectieve causale relaties. Het gegeven dat zowel voorwaartse als achterwaartse subjectieve connectieven tot een direct vertragingseffect leiden ten opzichte van hun objectieve equivalenten leidt tot de conclusie dat de cognitieve operaties die betrokken zijn bij de verwerking en representatie van beweringen en conclusies inherent complex zijn. De volgende grote vraag is dan: waarom kost de representatie van conclusies extra cognitieve energie? In dit proefschrift betogen we dat dit effect gerelateerd is aan de representatie van de interne wereld van de denkende persoon aan wie de uiting moet worden verbonden. In conclusies, als onderdeel van subjectieve relaties, is er altijd sprake van sprekerbetrokkenheid (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003); er is een denkende persoon die de verantwoordelijkheid neemt voor het uiten van de conclusie. Deze denkende persoon kan zijn de spreker, auteur of een personage in de discourse wiens redenering wordt gepresenteerd. Zodoende moet er bij de interpretatie van deze conclusies rekening worden gehouden met de ‘mentale ruimte’ van deze denkende persoon. In Hoofdstuk 4 en 5 hebben we systematisch onderzocht hoe dit proces zich verhoudt tot de verwerkingsvertraging in subjectieve vergeleken met objectieve causale relaties. In Hoofdstuk 4 benaderden we deze kwestie vanuit een mental space perspectief waarin onderzoeksvraag 3 centraal stond: RQ3 Wordt de verwerkingscomplexiteit van subjectieve causale relaties bepaald door de cognitieve processen tijdens het lezen die te maken hebben met de constructie van de mental space van de spreker of auteur als denkende instantie? Mental Spaces Theory (MST) (Fauconnier, 1994) (zie Hoofdstuk 4) is een theorie uit de cognitieve taalkunde die recent ook is gebruikt om het verschil tussen subjectieve en objectieve causale relaties te beschrijven (Sanders, Sanders, & Sweetser, 2009, 2012; Verhagen, 2005). Mental spaces zijn Samenvatting|213 conceptuele ruimten waarbinnen informatie gekoppeld aan tijd, ruimte, en personen ten opzichte van het hier en nu wordt gerepresenteerd. Wanneer taalgebruikers met elkaar communiceren bouwen ze een dynamisch netwerk van mental spaces, dat wordt aangepast met het verloop van de discourse. De mental space configuraties van subjectieve causale relaties zijn beschreven als meer complex dan die van objectieve causale relaties omdat in er in subjectieve relaties een extra mental space van de denkende persoon moet worden aangemaakt. De causale relatie dient vervolgens binnen deze space te worden geïnterpreteerd (Sanders, Sanders, & Sweetser, 2009, 2012). Relevant voor onze discussie is dat de connectieven want en dus, maar niet omdat en daarom, beschouwd worden als zogenaamde space builders die de constructie van nieuwe mental spaces activeren (Verhagen, 2005). In Hoofdstuk 4 is onderzocht of space builders in de context voorafgaande aan de causale relatie het verwerkingsverschil tussen want en omdat kunnen doen verdwijnen. Om deze vraag te kunnen beantwoorden hebben we twee oogbewegingsexperimenten uitgevoerd waarin korte nieuwsberichten zijn gemanipuleerd. In deze teksten werden subjectieve causale relaties met want (9a), en objectieve causale relaties met omdat (9b) verwerkt. (9) a. Het huidige niveau van de studenten is laag want slechts de helft haalt een voldoende voor rekenen en taal. b. Het huidige niveau van de studenten is laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. Anders dan in de voorgaande experimenten werden in dit experiment objectieve en subjectieve causale relaties gemanipuleerd die precies dezelfde S1 hebben, inclusief de eerste tekstregio na het connectief (‘slechts de helft’). Subjectieve contexten werden gecreëerd door space builders aan de titel en de context voorafgaande aan de causale relaties toe te voegen. Deze space builders bestonden uit evaluatieve bijwoorden en adjectieven, zoals verschrikkelijk, belachelijk en gelukkig, die duidelijk maken dat de tekst gepresenteerd wordt vanuit het perspectief van de auteur. Een offline beoordelingstaak, waarin de deelnemers gevraagd werd naar de intenties van de auteur, liet zien dat deze manipulatie van sprekerbetrokkenheid geslaagd was. Daarbij zorgde de aanwezigheid van de evaluaties voor langere leestijden van het vervolg van de tekst, dat in beide condities precies dezelfde woorden bevatte. Deze resultaten laten zien dat onze proefpersonen gevoelig waren voor onze manipulatie van space builders. Echter, deze manipulatie had geen enkele invloed op het verwerkingsverschil tussen want en omdat. Net als in de experimenten in Hoofdstuk 3 zorgde want voor een vertraging in het leesproces ten opzichte van omdat. Dit effect deed zich voor op het connectief, en op de eerste tekstregio na het connectief. 214|Samenvatting Deze resultaten doen vermoeden dat het verwerkingsverschil tussen want en omdat niet kan worden verklaard door de noodzaak van het aanmaken van een extra mental space van de denkende persoon. In Experiment 2 hebben we deze kwestie verder onderzocht door het materiaal minimaal aan te passen. Ditmaal werd in de subjectieve contexten ook de eerste zin van de causale relatie gemarkeerd met (nietzinsmodificerende) evaluatieve bijwoorden (10). (10) a.Het huidige niveau van de studenten is belachelijk laag want slechts de helft haalt een voldoende voor rekenen en taal. b. Het huidige niveau van de studenten is belachelijk laag omdat slechts de helft van de onderwijsuren wordt besteed aan rekenen en taal. Wederom was er geen effect van space builders op het verwerkingsverschil tussen want en omdat. Eerder in deze samenvatting hebben we besproken dat expliciete signalen in S1, zoals volgens Jan en waarschijnlijk, die de status van heel S1 modificeren tot een bewering of conclusie (11), het verwerkingsverschil tussen subjectieve en objectieve causale relaties doen verdwijnen. De evaluatieve elementen die we in Experiment 2 van Hoofdstuk 4 hebben gemanipuleerd signaleren wel de emotionele betrokkenheid van de auteur, maar ze modificeren niet de status van hele zin. Wanneer ze worden gebruikt zoals in (12), beïnvloeden dit soort markeerders de interpretatie van slechts een deel van S1. Aangezien deze evaluaties niet in staat zijn om de verwerkingsvertraging in subjectieve causale relaties op te lossen, concluderen we dat dit effect gerelateerd moet zijn aan de interpretatie van een van de zinnen in zijn geheel als iemands conclusie of bewering. Het lijkt erop dat het subjectieve connectief want deze interpretatie oproept. (11) Volgens Jan / Waarschijnlijk [is het huidige niveau van de studenten laag] (12) Het huidige niveau van de studenten is [belachelijk [laag]] In Hoofdstuk 5 hebben we verder onderzocht waarom de representatie van dit soort conclusies de cognitieve belasting vergroot. Aangezien beweringen en conclusies voortkomen uit een redenering, kwamen we tot de hypothese dat de cognitieve complexiteit van subjectieve causale relaties gerelateerd is aan dit onderliggende proces. Een redenering kan worden gedefinieerd als een “simulatie van de wereld, ingevuld met onze kennis” (Johnson-Laird, 2010, p.1). Deze omvat de constructie van een set van mogelijke mentale modellen die overeenkomen met een gegeven situatie in de wereld, op basis waarvan een conclusie kan worden herleid. Het is mogelijk dat, naast het feit dat subjectieve causale relaties verbonden zijn aan de interne wereld van de denkende person, ze ook een beroep doen op de lezer (of luisteraar) om de onderliggende Samenvatting|215 redenering te volgen, wat de cognitieve belasting vergroot. Deze hypothese heeft geleid tot de volgende onderzoeksvraag die centraal stond in Experiment 2 en 3 van Hoofdstuk 5: RQ5 Is het mogelijk om onderscheid te maken tussen redeneren en sprekerbetrokkenheid om de inherente complexiteit van subjectieve causale relaties te verklaren? In Experiment 2 hebben we ons gericht op het redeneeraspect van subjectieve causale relaties door de verwerking van het voorwaartse subjectieve connectief dus met het bijwoord blijkbaar, een zogenaamde inferential evidential, te vergelijken. Net als dus identificeert blijkbaar evidentie op basis van een redenering (Van der Auwera & Plungian, 1998). Maar in tegenstelling tot dus zijn evidentiële bijwoorden zoals blijkbaar gebaseerd op objectieve evidentie in de wereld, wat losstaat van de (subjectieve) overtuigingen van de spreker (Giannakidou, 2011; Nuyts, 2001); blijkbaar signaleert een zekere afstand tot mentale wereld van de spreker. Uit de resultaten bleek dat, vergeleken met daarom, blijkbaar niet tot een verwerkingsvertraging leidt. Deze uitkomst laat zien dat het gegeven dat conclusies voortkomen uit een redenering op zichzelf geen verklaring kan zijn voor het vertragingseffect in subjectieve causale relaties. In Experiment 3 is onderzocht of dit effect wèl verklaard kan worden door verschillen in sprekerbetrokkenheid. In dit experiment werd de verwerking van dus en blijkbaar vergeleken met het epistemische modale bijwoord waarschijnlijk. Met het gebruik van waarschijnlijk geeft de spreker een evaluatie van de waarschijnlijkheid van de volgende propositie. Tegelijkertijd verbindt de spreker zich niet volledig aan het waarheidsgehalte van die propositie: hij of zij houdt een veilige afstand (Nuyts, 2004, p.61). We postuleerden daarom dat dus een hoge mate van sprekerbetrokkenheid encodeert terwijl blijkbaar juist een lage mate van sprekerbetrokkenheid encodeert. Waarschijnlijk bevindt zich ergens in het midden van die schaal (13). (13) Mate van sprekerbetrokkenheid dus > waarschijnlijk > blijkbaar De resultaten van Experiment 3 komen overeen met deze verdeling in termen van sprekerbetrokkenheid. We observeerden langere verwerkingstijden na waarschijnlijk vergeleken met blijkbaar. Echter, dus zorgde voor nog langere verwerkingstijden. Op basis van de in dit proefschrift verkregen resultaten betogen we dat de verwerkingscomplexiteit van subjectieve causale relaties verklaard kan 216|Samenvatting worden door sprekerbetrokkenheid (Pander Maat & Degand, 2001; Pander Maat & Sanders, 2000, 2001; Pit, 2003). De conclusies en beweringen in subjectieve causale relaties hebben een bijzondere status omdat ze gelinkt zijn aan de ‘mentale ruimte’ van de denkende persoon – spreker, auteur, of personage in de discourse - die verantwoordelijk is voor het uiten van die conclusie. Zodoende zijn subjectieve causale relaties complexer dan objectieve relaties omdat taalgebruikers moeten begrijpen dat de informatie in de conclusie geen beschrijving is van de externe wereld, maar onderdeel uitmaakt van iemands kijk op de wereld. Dit is essentiële informatie omdat deze kijk kan verschillen van persoon tot persoon. Het is plausibel dat deze informatie diverse cognitieve operaties in werking die de cognitieve belasting vergroten. Conclusie De in dit proefschrift verkregen resultaten laten zien dat het onderscheid tussen subjectieve en objectieve causale connectieven direct van invloed is op de verwerking van de discourse. Wij concluderen dat het voor het begrip van subjectieve causale connectieven (en relaties) noodzakelijk is om een representatie te maken van de mentale wereld van de denkende persoon die verantwoordelijk is voor die causale relatie. Onze resultaten laten zien dat de cognitieve processen die betrokken zijn bij deze representatie de cognitieve belasting vergroten. Zodoende leiden talige markeerders die deze representatie activeren, zoals de subjectieve connectieven dus en want, tot langere verwerkingstijden vergeleken met markeerders die dat niet doen, zoals omdat en daarom. Deze conclusie sluit aan bij de veronderstelling dat causale connectieven fungeren als instructies voor verwerking die de lezer helpen bij het construeren van een coherente discourserepresentatie. We hebben laten zien dat deze instructies zo ver gaan dat ze de lezer informeren over het type causale relatie dat moet worden gelegd, subjectief of objectief. In Hoofdstuk 6 schetsen we een tentatief verwerkingsmodel dat illustreert hoe deze instructies er mogelijk uitzien. Zowel subjectieve als objectieve causale connectieven signaleren de richting waarin zij opereren. Objectieve connectieven specificeren dat de tweede zin (ook wel S2 genoemd) het gevolg is van de situatie in S1 (in voorwaartse relaties), of dat S2 juist de oorzaak is van S1 (achterwaartse relaties). Dit signaal activeert de constructie van de causale relatie tussen de twee zinnen. Of taalgebruikers deze relatie volledig zullen begrijpen hangt af van hun vermogen om de onderliggende inferentie te herleiden (als P dan Q). Dit wordt ook wel de inferentie functie van causale connectieve genoemd (Cozijn, Noordman, & Vonk, 2011; Noordman & Vonk, 1997). De richting van de relatie is ook relevant voor subjectieve causale connectieven. In dit geval signaleert het connectief dat S1 functioneert als Samenvatting|217 een bewering of conclusie op basis van het argument in S2 (achterwaartse relaties), of dat S2 functioneert als een bewering of conclusie op basis van het argument in S1 (voorwaartse relaties). Vervolgens is het aan de lezer om de denkende persoon die verantwoordelijk is voor de bewering te identificeren, en een mental space aan te maken die de gedachten van deze persoon representeert. In overeenstemming met theorieën over sprekerbetrokkenheid (Pander Maat & Degand, 2001, p.221) gaan we ervan uit dat deze persoon by default de spreker is. Daarna moet de bewering binnen de relevante mental space worden geplaatst. Net als bij objectieve connectieven kan het zijn dat subjectieve connectieven de lezer uitnodigen om de onderliggende causale inferentie te herleiden. Dit kan zijn door het toetsen van de causale relatie aan de bestaande wereldkennis van de lezer, of door de gereconstrueerde inferentie aan deze kennis toe te voegen. Een laatste bron van informatie die mogelijk in subjectieve connectieven is vastgelegd, is een signaal om de informatie in de bewering te evalueren. In het model worden slechts de primaire processen beschreven die door causale connectieven worden geactiveerd. Maar er zijn ook recursieve processen aan te wijzen die mogelijk betrokken zijn bij de representatie van subjectieve causale relaties. Ten eerste moeten taalgebruikers de representatie van relevante mental spaces actief houden in het werkgeheugen. Daarnaast kan het zijn dat de inhoud van een mental space moet worden bijgewerkt wanneer nieuwe beweringen of meningen voorbij komen in de discourse. Het spreekt voor zich dat dit model slechts een tentatief verwerkingsmodel is op basis van de empirische data die tot nu toe beschikbaar zijn. Het is bijvoorbeeld nog onduidelijk hoe de evaluatie van een bewering samenhangt met de achtergrondkennis over de persoon die verantwoordelijk is voor die bewering. Immers, om een bewering goed te kunnen evalueren is het belangrijk om ook iets te weten van de bron: Is deze persoon betrouwbaar? Heeft hij of zij een dubbele agenda? Hebben we doorgaans dezelfde mening? Het is onduidelijk wat er gebeurt wanneer dit soort informatie ontbreekt. Het kan zijn dat in dit geval de bewering ongeaccepteerd blijft. Maar het kan ook zijn de bewering wordt geaccepteerd zolang het argument waarop het is gebaseerd redelijk genoeg wordt bevonden. Anderzijds kan het in het geval van een zeer betrouwbare bron zijn dat het evaluatieproces in zijn geheel wordt overgeslagen en alle beweringen voor waar worden geaccepteerd. In vervolgonderzoek kan worden nagegaan wat de invloed is van dit soort factoren op de verwerking van subjectieve causale connectieven en subjectiviteit in het algemeen. De uitgelezen manier om dit te doen is door middel van interdisciplinaire 218|Samenvatting samenwerkingen tussen cognitieve taalkundigen en tekstlinguïsten aan de ene kant, en experimentele psycholinguïsten en sociaal psychologen aan de andere kant. Deze samenwerking zal bijdragen aan een beter begrip van de processen die betrokken zijn bij de verwerking van discourse, wat een essentieel onderdeel is van communicatie door taal. Acknowledgements Looking back at my PhD project I am very happy, but still a bit amazed, that somehow I made it to the end. I wrote a book. Of course there are many people who have helped me along the way and I would like to take the opportunity to thank you all. I apologize in advance to anyone I may have forgotton to mention. First of all, I thank my promotor Ted Sanders and co-promotor Pim Mak who never stopped believing in me, even when I did. Thank you for shaping my thoughts, polishing my writing and the good laughs during our meetings. Ted, thank you for including me in your VICI team and for the time and effort you have put into my supervision despite your crazy agenda. You showed me the world of discourse and that truly opened my eyes. Also, I very much respect your persistence in trying to get me to speak Italian, always surprising me with out of the blue buongiorno’s and grazie’s (sometimes there was some Spanish too I recall). Ecco, due parole in Italiano per te: grazie per tutto! Pim, I am grateful for everything you taught me about eye-tracking, doing experiments, and interpreting data. But more than that, I thank you for our conversations, irrelevant detours (let’s google this!), and for always being there to help me out. Somehow you helped me get back on the horse by convincing me to “just write up a boring story”. There are a number of people who have been of particular value throughout this project. First I thank the other members of the connectives mafia who were part of Ted’s VICI-project: Ninke Stukker, Pim Mak, Rosie van Veen and Ingrid Persoon. Thank you for the discussions and feedback that contributed to my research. A huge ‘thank you’ goes to Rosie van Veen for checking the English of parts of my dissertation (all remaining errors are my own!), helping me out with all kinds of things, listening to my complaints, for the fun we had (at conferences and in the office), and for agreeing to be my paranimf. Another special ‘thank you’ goes to Loes Koring, who turned out to work on subjectivity as well. Thanks for always being enthusiastic about my work and for our discussions on blijken, blijkbaar, lijken, lijkt me, schijnen, and waarschijnlijk J. It was nice to share the ups and downs of “finishing” with you, we made it! A word of gratitude goes to the people who have read parts of this dissertation and provided helpful feedback. Arnout Koornneef, Sandrine Zufferey and Kirsten Vis: thank you for your time and effort. 220|Acknowledgements I wouldn’t have been able to conduct so many experiments if it wasn’t for the Uil-OTS lab support provided by Iris Mulders, Theo Veenker, Warmolt Tonckens and Sjef Pieters. Special thanks to Iris Mulders for getting me into research in the first place and for making me fall in love with eye-tracking. I also wish to thank the people who have helped collect part of my data: Linda de Leeuw, Fang Li, and Susanne Kleijn. I also thank the CIW students Martijn Piggen, Klaas van Staveren, Jasper van Dijk, and Michelle van ‘t Hof, who helped collect part of the data for Experiment 2 in Chapter 5 as part of their Bachelor theses.

I owe a special ‘thank you’ to Marrit Müskens for being my paranimf and for all the good laughs: bedankt maat! As we reach the final part of these acknowledgements it is time to thank the people outside academia who have kept my feet on the ground. Manon, Laura, Lotte, Mariëtte, Petra, Linda, Kimberly, Ingrid, Ellen S, en Ellen N: thank you for being my friends, for distracting me with serious and not so serious stuff, and for putting things in perspective. In the end I owe everything to my family: my mother, my brother Sergio, and my sister Michelle. Thank you for the love and support you have given me. Mam, bedankt dat je mij altijd mijn eigen keuzes hebt laten maken en mij onvoorwaardelijk hebt gesteund in wat ik ook wilde doen. Even though I can only imagine what my father would have said about all this (probably lots of ridicule), I am sure he would have been so proud! Finally, the biggest ‘thank you’ of them all goes to Marc who put up with me on a daily basis. Thank you for being patient, understanding, and supporting. More importantly, thank you for being fun and crazy! Being around you has certainly helped lighten things up.
