Referential properties of pronouns influence sentence processing independently of structural complexity Yair Haendler & Flavia Adani Research funding: Ernst Ludwig Ehrlich Studienwerk Linguistics Department, University of Potsdam (www.uni-potsdam.de/aladdin/en; [email protected]) 1pro Background & research questions 3pro “I” Speaker /speaker/ Hearer Cognitively less demanding “It” Speaker Adults - OR + embedded 1pro are perceived as less complex than OR + embedded 3pro (both are less complex than OR + embedded full DP) (Warren & Gibson, 2002). /the owl/ Hearer Cognitively more demanding - In SRs filler-gap dependency resolution is less hard than in ORs → no pronoun effects are expected. (Ariel, 2001; Erteschik-Shir, 1997) Linguistic material Embedded Pronoun 1pro Subject Relatives (SR) 3pro Object Relatives (OR) Le mucche che mi stanno acchiappando Le mucche che io sto acchiappando The cows who me are catching The cows whom I am catching 'The cows that are catching me' 'The cows that I am catching' - Introduction of new discourse referents between filler and gap increases processing cost (Gibson, 2000) – more demanding for 3pro than 1pro. Children - OR + embedded pronoun are easier than OR + embedded full DP: the embedded pronoun attenuates the intervention locality effect (Friedmann et al., 2009). - In SRs there is no intervention locality effect → no effects of embedded pronouns are expected. Le mucche che lo stanno acchiappando Le mucche che lui sta acchiappando Research questions The cows who him are catching The cows whom he is catching 1) Does the 1pro/3pro asymmetry affect also SRs? 2) Does the 1pro/3pro asymmetry emerge in childrenʼs processing? 'The cows that are catching him' 'The cows that he is catching' 3) Do we find similar results across different testing methods? Eye-tracking visual-world experiment - Adults (N=19, mean age=27, 20-38) ; children (N=69, mean age=5;3, 4;1-5;11) 1pro 3pro - Task: watch animated videos and listen to accompanying test sentences. - Test sentences (N=36): question about the color of the target referent ( Di che colore sono le mucche che lui sta acchiappando? 'What color are the cows that he is catching?'). - Fillers (N=6): Di che colore sono le mucche con il fiore? 'What color are the cows with the flower?' - Response: adults & children were highly accurate on all conditions. Dependent variable: Proportion of target looks = Target /Target + Middle + Distractor Linking the pronouns in context: - Each trial was preceded by a video in which the animals of the scene were presented ('Here there are cows. And here is their friend, the lion'). - In 1pro trials, the middle animal was the narrator – Lilli the dog – alone ('I') or with her sister ('we'). We measure: How hard it is to identify the relative clause head as subject/object → this depends on fillergap dependency resolution → which is affected by the pronounʼs referential properties (1pro vs. 3pro). Adults Children - Main effect Gap (OR > SR), t=4.08. - Main effect Gap (OR > SR), t=12.78. - Main effect Pronoun (1pro > 3pro), t=-4.78. - Main effect Pronoun (1pro > 3pro), t=-14.07. - No interaction Gap:Pronoun, t=-1.78 - No interaction Gap:Pronoun, t=-.85. - No interaction Time:Gap:Pronoun, t's<|2|. - Interaction Time:Gap:Pronoun, t=2.19 (linear), t=-2.42 (cubic). Y-axis: Adjusted proportion of target looks (individual differences removed with remef ). X-axis: Time (in sec.), starting at auxiliary onset. Dashed line marks the sentence offset, followed by silence that was included to account for late effects. Analysis: Linear Mixed Models with empirical logit (Barr, 2008). Self-paced reading experiment - Adults (N=68, age=28, 20-44). - 32 test items (8 per condition). - 102 fillers. - Latin-Square design. - Non-cumulative SPR (Linger). - Comprehension questions – overall high accuracy rate. Analysis – Linear Mixed Models: - Main effect Pronoun (1pro > 3pro), t=-2.78 (AUX), t=-4.24 (VERB). Linking pronouns in context – preamble sentences: - No main effect Gap, no Maria era al mare con il fratello Paolo. interaction Gap:Pronoun, t<|2|. ('Maria was at the sea with the brother Paolo.') Paolo si è messo ad azzuffarsi con i vicini di ombrellone. ('Paolo started to fight with the people of the beach umbrella nearby.') Discussion Answering the research questions 1) 1pro/3pro asymmetry is similar in SRs and ORs. 2) Children show the same eye-movement pattern as adults. 3) Similar outcome in eye-tracking and self-paced reading. - More target looks in ORs: preference to look at the patient before the linguistic input is heard – gaze pattern changes following critical input. - Pronoun effects in SRs: not related to syntactic complexity – neither in terms of intervention locality (Friedmann et al., 2009), nor of integrating discourse referents during filler-gap dependency resolution (Warren & Gibson, 2002). - Referential properties of 1pro/3pro: influence sentence processing independently of structural complexity – discourse accessibility for 1pro is cognitively less demanding than for 3pro.
