Child Development, March/April 2004, Volume 75, Number 2, Pages 377 – 394 On the Nature of Emotion Regulation Joseph J. Campos, Carl B. Frankel, and Linda Camras This paper presents a unitary approach to emotion and emotion regulation, building on the excellent points in the lead article by Cole, Martin, and Dennis (this issue), as well as the fine commentaries that follow it. It begins by stressing how, in the real world, the processes underlying emotion and emotion regulation appear to be largely one and the same, rendering the value of the distinction largely for the benefit of analysis. There is an extensive discussion of how the same processes can generate emotions (i.e., are constitutive of emotion) and account for variability of manifestation of emotion in context (i.e., regulate them). Following an extensive review of many of the principles involved in emotion and emotion regulation, the paper presents implications for developmental study of infants and children, includes several methodological recommendations, and concludes with an analysis of the extent to which contemporary affective neuroscience contributes to the study of emotion and emotion regulation. Albert Einstein supposedly stated that a scientific explanation should be simple, but not too simple. In this commentary, we strive to meet Einstein’s maxim. We attempt to glean many of the insights about emotion regulation contained in the provocative lead article by Cole, Martin, and Dennis (this issue), as well as in the various commentaries it spawned. Those commentaries sometimes endorse, frequently modify, and sometimes reject ideas presented in the lead article. However, both the lead article and the commentaries address limited aspects of emotion regulation. Our task is thus one of supplementing and briefly systematizing what we believe it takes to explain emotion regulation and its relation to the concept of emotion. Based on the principles we provide, we intend to take up the challenge posed by Bridges, Denham, and Ganiban (this issue) and point to new and fruitful directions for studies in emotion regulation relevant to basic researchers, clinicians, and applied developmentalists alike.

The term implies the existence of two phenomenaFone involving a set of processes related to the generation of emotion, and the second a different set of processes coming after the elicited emotion and involving management or mismanagement of the generated emotion. Indeed, the endorsement of such a two-factor model is a major theme at the conclusion of the lead article by Cole et al. (this issue), in which they recommend research approaches that first generate emotion, then study how regulatory process change the elicited emotional state. Such a two-factor approach to emotion regulation is both simple and commonsensical. How often has each of us experienced the two factors in ourselves? First, we feel overwhelmed, such as after an intense frustration (creating the ‘‘urge to attack someone’’), then we ‘‘count to 10,’’ ‘‘take a deep breath,’’ or ‘‘curb our wrath,’’ hoping to modulate or prevent altogether the manifestation of behaviors we deem undesirable. This two-step experience is so compelling it has become the canonical phenomenon of emotion regulationFthat which most researchers want to explain. A corollary of the two-factor approach to emotion regulation also seems simple, straightforward, and intuitively appealing. That corollary is the belief that there are ‘‘good’’ emotions, such as joy, relief, and enjoyment, and ‘‘bad’’ emotions, such as anger, shame, and scorn. The explanatory task for those researching emotion regulation is then to derive r 2004 by the Society for Research in Child Development, Inc. All rights reserved. 0009-3920/2004/7502-0010 378 Campos, Frankel, and Camras principles and procedures to help the individual maximize the good emotions and minimize the bad emotions. Many, if not most, researchers on emotion regulation take as their starting point the identification and the eradication of phenomena such as infant crying, temper tantrums, school-age fighting, taunting, harassment, social withdrawal, and inappropriate expressions of emotions, and substitute socially more acceptable emotional behaviors. In this sense, there are many points of convergence between researchers studying emotion regulation and those emphasizing the merits of ‘‘positive psychology’’ (see Lazarus, 2003,and subsequent commentaries on his treatment of positive psychology). The two-factor principle and its corollary thus are face valid. But are they appropriate for an understanding of what emotion regulation is? In this paper, we say, ‘‘No,’’ and argue that, as in Einstein’s maxim, the canonical approach is too simple. In the first place, we argue that there is no ‘‘pure’’ emotion, if by that is meant an emotion that ever exists in an unregulated manner. If so, there is no first factor to account for in a two-factor theory. Furthermore, even if there were such a phenomenon as a pure emotion, we would have no way of knowing it. A pure emotion would have clear indication of its existenceFindications that could serve as its operational definition. Unfortunately, emotion is not readily amenable to operational definition. More specifically, no one has ever convincingly presented coherent facial, vocal, gestural, physiological, or cerebral indexes that approximate a 1:1 relation to an emotional state (Davidson, Jackson, & Kalin, 2000). We have no gold standard, no ostensive definition of emotion. Instead, we have a state of affairs in which (a) many behaviors can be in the service of a single emotion, and (b) the same behavior can be in the service of multiple emotions. This observation suggests that extraordinary caution is in order about the many difficulties of reliably identifying the emotion that subsequent processes then, ex hypothesis, modify or regulate. To illustrate the first part of this observation, consider how two morphologically divergent reactions can reflect the same emotion, shame. Shame is the emotion of avoiding social interaction with a person who disapproves of one’s actions.1 In one 1 A clarification is in order here. We believe that shame, like all other emotional states, is not merely a feeling state that precedes behavior, nor is it the behavior itself. Rather, shame is the evaluation by individuals of the condition they find themselves in and their attempts to deal with that condition. (In the case of shame, the condition is one of finding oneself being observed in a disapproving manner by another and attempting to discontinue that manifestation of shame, the person avoids social intercourse by hiding his or her face, or moving into the social background; in another case, the person avoids the social intercourse by distracting the disapproving person through rapid banter and change of venue. Notice that though morphologically different, the divergent responses are in the service of the same endFhiding the self from the disapproved act and the self’s role in that act. To illustrate the second part of the observation, consider how response inhibition can reflect two very different emotions. Inhibition can reflect the emotion of shame when it results in behavioral arrest that cuts off social interaction following disapproval, while morphologically similar inhibition can reflect fearFthe emotion linked to threat to the integrity or safety of the selfFby avoiding a danger, such as in fear of a predator. There is a second difficulty in identifying emotion: We cannot use an environmental event (an ‘‘incentive event,’’ as Kagan, 1978, called it) as a proxy for an expected emotional outcome. For instance, arm restraint is frequently mentioned in this set of papers in connection with the generation of anger. In other papers, loss of support has been used as a proxy for fear. However, any eliciting event can produce a multiplicity of emotions. In addition to anger, arm restraint can initially elicit game-like smiling, sadness, and disappointment at being put into what appears to be an undesirable state, or uncertainty in the infant about what is going on with the arm restraint (see Stenberg & Campos, 1990). Loss of support elicits avoidance, laughter, or puzzlement, depending on context (Sroufe & Waters, 1976). As Sroufe (1996) noted, it is the meaning of the event, and not its physical composition, that determines the emotion. The difficulties inherent in operationalizing emotion by reference to expression, behavior, or eliciting stimuli does not mean that emotion cannot be identified. How then does one do so? The answer given by some contemporary emotion theories (Campos & Barrett, 1984; Frijda, 1986) leads to one reason why emotion and emotion regulation cannot be dissociated from one another. That answer is as follows: To classify behaviors as emotion A (e.g., shame) or as observation or end its disapproving nature.) Feeling accompanies the evaluation the person makes of the situation and assimilates into the evaluation of the situation the sensations from the viscera and skeletal musculature. Feeling can register powerfully in consciousness and serves important monitoring functions, described later in this paper. Nonetheless, feeling is not the cause or defining attribute of the emotion, any more than color is the cause or defining attribute of an object. From Another Perspective: The Nature of Emotion Regulation emotion B (e.g., fear), we must understand the function that the selected behaviors serve in interaction with the world, how those behaviors are related to the problem the person is facing, and how they are playing a role in solving that problem. The function of the behavior, then, and not its morphology, is the organizing principle behind the classification of emotional reactions; it is what makes possible differentiating anger from fear, or any one emotion from any other. In other words, emotional responses can be equipotential. Once one admits equipotentiality, one necessarily has accepted regulatory principles into one’s conception of emotionFspecifically, the person’s selection from a palette of different responses that are suitable for meeting a person’s goals, and in addition, monitoring the effectiveness of the choice. A One-Factor Alternative: Emotion and Emotion Regulation Are Concurrent, Coterminous Processes In preference to a two-factor model of emotion regulation, we propose instead a unitary model that is based on general systems theory as well as the writings of Barrett and Campos (1987), Frankel (1999, 2002), Frijda (1986), Holodinski and Friedlander (in press), and Lazarus (1991). Where appropriate, we also use conceptualizations explicit in the lead article by Cole et al. (this issue). The model we present has four qualities we find highly desirable. First, the approach is designed to be more integrative, allowing one to explain what both emotion and emotion regulation involve, as well as how they are typically indissociable. Second, it allows one to account for how bad emotions can be good in context, and how good emotions can be inappropriate and misregulated in other contexts. Third, it places the human being into ever larger but concentric circles of social influence, from the dyadic to the cultural and historical. Fourth, it provides novel heuristic principles that can give us new insights into emotion and emotion regulation across development. Before we present this model, we would like to make two caveats. The first is that, analytically and conceptually, there can be differences between emotion and emotion regulation. This is an important qualification to what we are about to describe. However, such a conceptual distinction does not imply ontological distinctivenessFthat each process has a separate, real existence that corresponds to the mental distinction. Such separate existence is what the lead article by Cole et al. (this issue) somewhat ambivalently concluded and many commentaries accepted. We do not accept the assumption that in 379 real life first comes one and then comes the other. Rather, emotion and emotion regulation are conjoined from the beginning as one observable processFa process that reflects the attempt by the person to adapt to the problems he or she encounters in the world. There is a second caveat. We do believe that something like the two-step process (first becoming angry, then counting to 10) does appear to take place. However, such two-step processes we believe prove amenable to explanation in the same manner as the more typical manifestation of emotion, especially when one considers that emotions, contrary to the opinions of many (e.g., Ekman, 1992), unfold over time, are only rarely instantaneous or micromomentary, and often are elicited in conjunction and in complex ways with other emotions. Therefore, apparent two-step manifestations of ‘‘emotion then regulation’’ should not be taken as the prototype of regulation. Such two-step examples are at best exceptions to the rule, though we later argue that they are not even exceptions. Definition of Emotion and Emotion Regulation Many of the contributions to this special section of the journal failed to make clear their definitions of the concepts they were attempting to explain. They assumed them. To their credit, Cole et al. (this issue) did make such an attempt. To avoid misunderstanding, we begin our narrative with our brief working definitions of emotion and emotion regulation. Our working definitions are based on the following assumption: Human beings encounter problems, solutions to problems, or ways of sidestepping problems in the course of their adaptation to social and nonsocial demands of the world in which they live. These encounters constitute the setting events for the generation of emotion and emotion regulation, even for positive emotions such as love. Both emotion and emotion regulation center on dealing with the problems of existence and of adaptation to the reconstructed past, the attributed present, and the predicted future. Here, then, are our definitions, based on the assumption just articulated. Emotion is the process of registering the significance of a physical or mental event, as the individual construes that significance. The nature of the significance (perceived insult, threat to life, deprecation by another, relinquishment of a desired state, avoidance or resolution of a problem, etc.) determines the quality of the emotion. The degree of perceived significance determines the magnitude of the emotional response, as well as its urgency. 380 Campos, Frankel, and Camras Emotion regulation is the modification of any process in the system that generates emotion or its manifestation in behavior. The processes that modify emotions come from the same set of processes as those that are involved in emotion in the first place. An exception is when a social agent, often mobilized by his or her own emotions, intervenes to address one’s problem (as when a mother soothes a hungry or frightened baby, or when an adult breaks up a fight between children). Regulation takes place at all levels of the emotion process, at all times the emotion is activated, and is evident even before an emotion is manifested. How Emotion and Emotion Regulation Draw on the Same Processes We propose that emotion and emotion regulation (recall, differentiated here not ontologically but for the purpose of analysis) interact at all phases of their generation, manifestation, and termination. We illustrate these points, first by arguing that emotion and its regulation occur concurrently from the outset of an emotional transaction; second by showing how emotion and emotion regulation are embodied in processes that are almost entirely coterminous; and third by proposing that emotion and regulation exhibit extraordinary variability, befitting the impressive plasticity the human shows in adapting to problems posed by the social and nonsocial world. We also discuss canonical cases of emotion regulation (e.g., wanting to hit someone but counting to 10 instead) and argue, as noted earlier, that such cases are not distinctive instances of emotional processing. Emotion Regulation Is Evident Even Before an Emotion Is Elicited In this section we discuss the point made by Cole et al. (this issue) and elsewhere that the proper study of emotion and emotion regulation involves, first, a sequence of generating emotion, and then, regulating it by processes different from those of its generation. Cortical inhibition can precede emotion elicitation. There is widespread agreement that inhibition is a hallmark of regulation. It is also a principle evident in emotion generation because in the course of one emotion or set of emotions being generated, other emotions and emotion sets are simultaneously and typically held in check. If we admit inhibition as a regulatory process, we must admit that regulation plays a role even before the elicitation of an emotion. In many cases, the elicitation of emotion is as much a function of the release of existing inhibition as it is the direct activation of cerebral emotion circuits. In other words, emotions reflect the organization of several cortical and subcortical centers in an intricate network of mutual influence, some of which preexist the transaction with the significant event. This point was made clearly by Goldsmith and Davidson (this issue) and by Lewis and Stieben (this issue) in their commentaries. Release from inhibition has been proposed for many years in the explanation of important phenomena in brain – behavior relations. For instance, foreshadowing recent neuroscientific findings, Sokolov’s (1963) studies of orienting showed that the cortex actively inhibits arousal centers in the brain during environmental stimulation. That inhibition is released only when (a) a process of cortical comparison of stimulus input against neuronal models of prior stimulation is completed, and (b) a mismatch occurs between current stimulation and sensory stores of prior stimulation. The release of inhibition then permits stimuli coming through alternative pathways to arouse the reticular formation and other brain structures that produce the cortical activation, behavioral arrest, and autonomic response patterns associated with orienting. Sokolov’s work, then, showed that orienting responses cannot be said to be elicited by external events but rather by a complex orchestration of cerebral phenomena that are only partially linked to concurrent stimulation. As Goldsmith and Davidson (this issue) and Lewis and Stieben (this issue) implied, theories of emotion and emotion regulation must make clear how they deal with preexisting regulatory processes. Such theories often do not. The end of an apparent sequence can influence the beginning of the sequence. A second factor affecting the generation of emotion from the start is the assessment the person makes, automatically or voluntarily, of one’s capacities to respond to the event one is facing. If a person can deal with an event, the event loses much of its emotion-generating impact. It is short-circuited. For instance, a parachute jumper whose skill is so proficient and whose confidence in a successful parachute jump is very great will not experience jumping from an airplane as stressful (Fenz, 1974; Fenz & Jones, 1972). It is ‘‘no sweat’’ and possibly not even thrilling. Remove the skill or remove the confidence and the emotion becomes proportionally more negative and intense. Therefore, factors apparently late in the process of emotion generation (choice of response and confidence in outcome) can affect the unfolding of one’s emotional From Another Perspective: The Nature of Emotion Regulation response from the outset of an emotional encounter. Emotion regulation is not a linear process first involving the elicitation of emotion. The importance of short-circuiting of appraisals. A third factor that can affect the initial registration of the significance of an event also involves short-circuiting of emotion generation. Lazarus and Alfert (1964) called this form of short-circuiting a form of cognitive appraisal, but for our purposes, it is better called a cognitive preappraisal. In the Lazarus and Alfert study, research participants who were given instructional sets to the effect that a circumcision rite about to be viewed on film was not really very painful and was welcomed by the circumcised adolescents did not show the same level of stress as control participants given no such instructional set. In this entire line of research by Lazarus (1999), future emotional reactions were affected by the manipulation of expectations that preceded the emotional transaction. Nichepicking: Choosing one’s environment influences one’s emotions. A fourth factor is what we (Campos, Mumme, Kermoian, & Campos, 1994) and Eisenberg and Spinrad (this issue) have called nichepicking, a term inspired by an article on genetics and environment by Scarr and McCartney (1983). Nichepicking refers to the person avoiding the occasion in which an undesired emotion is likely to become activated or choosing settings in which desired emotions will be likely. An example of nichepicking comes from work in temperament. Shy infants (e.g., Kagan, in press) often choose to hang back and not join social groups until they are more comfortable with what is expected in that environment; they are slow to warm up, and they give themselves a chance to scout out the situation and learn expectations before joining social activity. A clinical example is milieu simplification (Goldstein, 1939), for example, airplane phobics choosing not to fly. A commonplace example includes thrill seekers traveling to amusement parks and places where thrills abound. Nichepicking is a highly effective means of regulating emotion at the outset by minimizing the experience of undesired emotions and maximizing the experience of desired emotions. Emotion regulation, in the forms we have mentionedFcortical inhibitory processes, awareness of response potential, interpretation of eliciting circumstances, nichepicking, and doubtless several othersFcan thus precede the elicitation of an emotion, in some cases prevent the manifestation of an emotion in its entirety, and in still other cases change the quality of the emotion. It seems inescapable to conclude that regulation and emotion generation mutually interact from the outset. 381 The Same Processes That Generate Emotions Regulate Them As we noted earlier, there are few (some would say no) environmental stimuli that intrinsically elicit emotion of any sort. Rather, emotion is the result of a person – event transaction, a relational phenomenon whereby an event is assimilated to a process significant to the individual. There are at least four such processes that render an event significant: (a) the person’s goals; (b) hedonics (i.e., the generation of pleasure or pain, or forecasts of a pleasurable or painful outcome); (c) emotional communication, including the expressive reactions in the face, voice, or gestures of others, as well as language, all of which can convey the reflected appraisals of others (Cooley, 1902; Mead, 1934) and are crucial for socialization, inculcation of values, and cultural transmission; and (d) past experiences, including those related to parent – child interaction and to socialization, and exposure to and assimilation of cultural rules and norms (in the interest of cogency, we do not elaborate on this fourth source of signification separately from the prior three but interweave its relevance throughout the paper). We now show how each of these processes plays a role both in the generation of emotion and in its regulation. We call the former role, following Levy (1973), the constitutive aspect of emotion, and the latter role the regulatory aspect. Emotions are constitutive because the person constructs the significance of events by linking events to some personal value or relevance, or coconstructs the significance of events by sharing with others. The constitution of emotion in a transaction yields meanings that are non-neutral; they are motivating. Emotion is regulatory insofar as the person, in some way, selects responses, sequences them, targets them, and monitors their impact on the problem that set the stage for the emotion. Here, again, is an instance where a distinction is conceptual but not ontological. We explicitly posit that all but severely pathological of brains are organized so that the act of appraising the significance of events ineluctably starts to motivate the kinds of things one might do in response. Constitutive and regulatory aspects are conceptually distinct only because they have a sequential dependency: In representing what happens when in an emotional state, people almost always attribute an initial construal of the event before they construe what to do about it. However, people cannot start to appraise the significance of an event without starting to be motivated to respond, and to start regulating their motivation, 382 Campos, Frankel, and Camras their response selection, and their subsequent acquisition of information to appraise. Hence, both constitutive and regulatory aspects of emotion and emotion regulation are aspects of a unitary process (see Frankel, 1999; Frankel & Ray, 2001). Constitutive and regulatory aspects of emotion generation related to goals. There seems to be little argument that there is a link between the generation of emotion and the assimilation of an event to one’s goals. For example, if an event facilitates goal attainment, joy ensues, constituting the affective meaning of the event for the person who has the goal. If something blocks goal attainment, anger ensues; if an event results in relinquishing a goal, sadness takes place. The list of linkages of events to goals is long and quickly becomes complicated. These linkages have been articulated clearly in the recent book by Scherer, Schorr, and Johnstone (2001), and earlier by Frijda (1986) and Barrett and Campos (1987). We do not summarize the list here. Moreover, as we remarked earlier, there is an important implication of the now-accepted principle of event – goal transaction; namely, by virtue of an event being assimilated to a goal, that transaction also creates a regulatory constraint such that the responses selected and deployed by the person must be in the service of the goal of that transaction. The regulatory behavior one observes in an emotional episode is typically not reflexive, as some theories of emotion hold (e.g., Plutchick, 1980). As a general rule, if a person deploys an instrumental response, that response will reflect an attempt to establish, maintain, or change the relation of the person to his or her environment to help attain that goal or, in some cases, to relinquish it. Instrumental (voluntary) behaviors illustrate this point best: When one is afraid, one selects a response, like freezing or running, aimed at eliminating the threat. Expressive reactions less obviously show the same purposiveness. If the person deploys an expressive response (facial, vocal, or gestural), the response will also be in the service of a goal: It will become an appealFa social signal designed voluntarily or automatically to attain an end state through the intermediary of a social other (Scherer, 1992). Even when a person fails to manifest a response (e.g., stilling behavior in fear, or behavioral inaction in passive aggressiveness), the absence of behavior can directly or indirectly also be in the service of a goal, in a manner similar to active behaviors. Contrary to ethics, in emotion the end does justify the means, or at least the means reveal what end the person is seeking. The fact that emotions are linked to goals requires rethinking the proposition that emotion regulation necessarily involves change. We consider this proposition intrinsically underspecified and, in one important sense, incorrect. First, the proposition must be made more specific, in a way that demands explicit consideration of the end state toward which regulation is allowing change to take place. Change per se is chaotic, unless and until it is controlled. For example, we consider an environment, the temperature of which is regulated by a thermostat, to involve not change but rather change centered around a set pointFthe ambient temperature desired by the occupants of the room (see the incisive points made by Hoeksma, Oosterlan, & Schipper, this issue). Change around a set point is change that is controlled, in this case, by the thermostat’s regulatory functioning. Lacking a principle of control that accounts for the direction of the temperature change toward some final state, change in temperature would be random or unidirectional, not corrected by a set point (or, in the language of dynamic systems theory, an attractor). Second, we also believe there is one sense in which the equation of regulation with change is incorrect. In a regulatory system, the maintenance of constancy is just as important and effortful as variations around a set point. Emotion frequently involves constancy of behavior, as when we identify what we need to do to reach a goal and keep at it until we attain the desired outcome. Empirical studies have shown that suppression of emotional display (i.e., maintaining one’s calm demeanor despite an upset) is very effortful when the person’s goal is no change of expression in response to an emotional encounter (Gross & Levenson, 1993). We thus prefer the term control to change when describing emotion and emotional regulation. The term control also gives us a method for identifying what changes (or absence of changes) are dysregulated. In emotion, a selected response or set of responses can be too intense or not intense enough, they can be of the wrong quality in a particular context, or they can be in violation of a social norm, again in certain contexts. In other words, the control principle can malfunction, resulting in undesired outcomes or outcomes attained with means that create more problems in the future. The concept of change is ambiguous in a way that the notion of control is not. Constitutive and regulatory processes related to hedonics. The same dual function of being constitutive and regulatory applies to hedonicsFthe pleasures and the pains we experience in many transactions in life. Pleasure and displeasure are meaningful experiences in and of themselves. The best illustration From Another Perspective: The Nature of Emotion Regulation of the constitutive role of hedonics in the generation of the emotions is in the emotions of desire and aversion (Frijda, 1986). Desire is the deployment and regulation of behavior in the interest of attaining a consummatory endFsuch as sexual intercourse, eating a delicious meal, or satisfying one’s thirst (other uses of the term desire are metaphorical). Aversion is the oppositeFbehaving and modulating behavior to avoid worse hedonic states than the one currently being experienced. Desire and aversion therefore exist because of hedonic processes. Hedonics also are regulatory. They are feelings that provide one of the ways by which we monitor our progress toward goals (Frijda, 1986), leading us to modify our behavior when we appear to be straying from our intended outcome or keep our behavior ‘‘steady as she goes’’ as we move toward an outcome. Without such hedonic signals, we might know that we are moving toward or away from a goal, but we will not be very motivated to change our behaviors to get back on track. Hedonics also are crucial in emotion and emotion regulation because these phenomenological qualities can become dissociated from their roles as signals in the service of regulating behavior toward a goal and instead become ends in themselves. In contrast to the role of hedonics in desire and aversion, wherein we typically seek consummatory responses that have as an accompaniment strong hedonic components, the hedonics of addiction involve no consummatory responses. Hedonics can thus shift from a monitoring signal and an accompaniment to consummation to an end in itself. When that happens so completely as to undermine the fabric of workplace and interpersonal relationships, hedonic processes have become addictive. Hedonics can be an aspect of an end state, part of monitoring progress toward a goal and a directly sought experience (an affective high; the pleasures of the senses). The signaling role of hedonics is critically important in the form of behavior regulation called emotion-focused coping (Lazarus & Folkman, 1984). There are times when the unpleasantness experienced in dealing with the problems of existence become so great that we direct our attention to controlling the feeling state and not to addressing the problem faced in life. Such emotion-focused coping may be manifested by self-medicating with alcohol or other mood-altering substances, or invoking the defense mechanisms of the ego. Such defenses, such as denial, displacement, reaction formation, repression, and so on, are marked by their not being realistic solutions to certain circumstances; such defense mechanisms can lead to major physical or health 383 benefits for the individual. Lazarus (1983), for instance, reported in one study that patients who engaged in forms of denial before surgery recovered better from surgery than others who did not use such defenses. The hedonic basis of emotion and emotion regulation was singular by its absence in the lead article by Cole et al. (this issue) and the associated commentaries. We believe such omission must be corrected in future treatments of emotion and emotion regulation. Constitutive and regulatory processes related to emotional communication. Social signals of others are also both constitutive and regulatory. By social signals, we mean the manner by which the emotions of others are manifested in facial, vocal, or gestural ways (we treat the role of language in generating and regulating emotion in this section but separately from what we call social signals.) Social signals are important in any treatment of emotion and emotion regulation in at least three ways: (a) they can generate emotion in another, both directly and indirectly; (b) they influence both the quality and the intensity of an emotion manifested by another personFthat is, they regulate the behavior of others; and (c) they illustrate how ‘‘no man is an island, entire unto himself,’’ because social signals, along with language, are one of the primary means by which the person is embedded in dyadic, family, ethnic, and cultural contexts; is exposed to social rules; and acquires the social norms that determine the generation and regulation of many emotions. Few people now doubt that social signals are regulatory of another person’s behavior. The large body of literature on social referencing (Campos, Thein, & Owen, in press; Saarni, Mumme, & Campos, 1998) has documented that from 8.5 months of age, facial, vocal, and gestural signals directed from an adult toward a baby can affect the child’s behavior toward that event. At earlier ages, social signals from others also powerfully affect the infant’s emotional responses, though in this case the social signals are not directed toward a third event but rather toward the child personally (in what Trevarthen, 1998, called primary intersubjectivity). It is not very widely recognized that social signals can be constitutive of emotion. That is, the fact of one person having an emotion can itself generate an emotion in an observing person, without reference to the event that triggered the reaction by the observed person. One example of such a constitutive role is the phenomenon of emotional contagion (Hatfield, Cacioppo, & Rapson, 1994). Under certain circumstances that are not well understood, one person’s 384 Campos, Frankel, and Camras emotional expressions can generate a like emotional state in someone perceiving that expression. This phenomenon is so fundamental that aspects of emotional contagion can be seen in the contagious crying observed in neonates (Martin & Clark, 1982; Sagi & Hoffman, 1976; Simner, 1971) and in a multiplicity of other contexts, including contagious laughter, fear, and disgust (McIntosh, Druckman, & Zajonc, 1994). More recently, Campos et al. (in press) proposed a second way in which social signals are constitutive of emotion. They held that social signals play a role in the generation, and in the social construction, of the emotions of pride, shame, and guilt. They noted that pride differs from joy insofar as joy can take place following success (Sroufe & Waters, 1976), including the detection of contingency between a response and an outcome (Watson, 1971). Joy need have no social context, though it usually does have one. However, the context of eliciting pride necessarily involves the reflected appraisals of the parents or significant figures in the environment as manifested in their enthusiastic applause, vocalizations, gestural expansiveness, and words of praise. When internalized, these reflected appraisals become the basis of pride. Indeed, the puffed-up chest and the expansive gesturing of the arms indicative of pride may be internalizations in the child of the behaviors the child observes in the parents. The perception of the approval of a significant other is itself significant. The constitutive role of social signals in shame is similar but involves the expression of different emotions by the significant figure in the environment. There probably is a precursor emotion to shame, as joy is to pride. If so, the precursor may reside in the disappointment and frustration experienced by a child when encountering failure at a task. However, in shame as in pride, the reflected appraisals of a significant other convert the emotional response observed in a given situation to a shameful one. Shame is constituted by the disappointment, the anger, the verbal disapproval, and the scorn or contempt the other person directs at the target person. Without that opprobrium and without the emoting person being significant to the perceiver of the social signals, there is no shame. The fact of a significant other’s disapproval itself has impact. It is interesting that some emotions do not play a role in generating shame. One example is the fear expressed by others. In contrast to the emotions described previously, fear expressions by the other directed at the person doing the disapproved act does not appear to generate shame. However, fear does potentially play a crucial role in the generation of guilt, as does the suffering, sadness, or pain experienced by another to the extent that one attributes these emotions to one’s actions. As with shame, not every emotion attributed to one’s behavior is the source of guilt. One does not feel guilty if the person whom one has hurt shows scorn, anger, or contempt toward the perpetrator, nor does the perpetrator feel guilt if the aggrieved other laughs or smiles. The constitutive role of social signals is thus specific to specific emotions. What we propose here is not in line with circumflex models of emotional expression that reduce the latter largely or exclusively to factors such as pleasantness or unpleasantness and level of activation (Russell, 1980). Emotional signaling, being constitutive exchanges involving specific interpersonal meanings, has different effects depending on the context in which the signaling takes place. These considerations about pride, shame, and guilt lead us to the conclusion that the principles involved in the generation of emotion and the regulation of emotion are largely the same. Moreover, social signals, along with the use of language, constitute the major route by which the child is exposed to the norms and rules of the larger community within which the child operates. Culture can be said to be, among other things, a system of values (Saarni et al., 1998). Values are best communicated by the combination of verbal and paralinguistic sources of communication. Raver’s (this issue) commentary raises many crucial points about how culture and ethnicity affect the generation and the regulation of emotion. Culture, itself a collection of shared constitutive and regulatory processes, affects emotion and emotional regulation in many ways: by affecting what is important or not important to oneself, by determining which behaviors are deemed appropriate and which are not, and by specifying how one should feel and behave in certain contexts (e.g., Hochschild, 1979). A good illustration of the relevance of culture to emotion and emotion regulation comes from comparisons of the inhibited temperamental style described by Kagan (in press) as evaluated in American and Chinese cultures (see Holodinski & Friedlander, in press). In this country, temperamental inhibition is not highly valued; most of us prefer our children to be assertive, bold, and sociable. Consequently, we often link temperamental inhibition to emotional dysregulation. In China, by contrast, temperamentally inhibited children are valued (Chen, Rubin, & Li, 1995). Shyness is considered to be an indication of willingness by the child to obey the rules of the culture, of being studious and hard working, and of From Another Perspective: The Nature of Emotion Regulation keeping his or her place in the culturally prescribed order of status. This illustration, along with the examples enumerated by Raver (this issue), should lead to caution about equating certain types of behavior (such as shyness) as bad or dysregulated and other types of behavior as good or well regulated. Often, what is good or bad is a function of the context and the culture in which one is growing up. A second example is relevant to this point. Many studies of emotion regulation center on the control of aggressive or hostile behavior in children (Garber & Dodge, 1991). Those studies have as their aim the identification of the etiology of aggressive behavior and the steps that can be taken to control such aggressiveness. However, in some cultures aggressiveness is not perceived as bad. In her study of toddlers growing up in Baltimore, Miller and Sperry (1987) documented how mothers socialize their toddlers to engage in aggressive behavior in the interest of defending themselves in a neighborhood where such hostile behavior is often called for. Miller and Sperry reported how mothers socialized their toddlers to be aggressive in a manner appropriate to their environment by calling them sissies when the children cried and did not counterattack following an assault by someone else. Yet the mothers did not give their child carte blanche to behave brutally. If the child showed aggressiveness when the mothers thought there was no circumstance they deemed appropriate for the aggressiveness, they called the toddlers spoiled. The point here is that the mothers of these children had values that differed in significant ways from those of the majority culture, instilled those values through paralinguistic and verbal means (teasing, name calling, showing disapproval of manifestations of pain or suffering, and emotionally encouraging aggressiveness the mothers deemed appropriate). To call anger and aggressiveness good or bad independent of the context in which emotion is shown is thus an error. Taken as a whole, these studies have documented how powerfully factors of emotional communicational (including linguistic factors) enter into the socialization of emotion and emotion regulation behaviors in toddlers, and how the culture can determine whether the same behavior is valued positively or not. Explaining ‘‘canonical’’ instances of two-factor emotion regulation. What we have called the canonical manifestation of emotion regulation (i.e., first one has an emotion; then one regulates it) is in our opinion a form of conflict resolution. It is also a kind of emotion regulation that involves much more 385 socialization, experience, and cognitive processing capabilities than the types of emotion and emotion regulation shown by the young child. Above all, it reflects a much more voluntary and willful self-regulation than is the case for the type of emotion regulation seen in infants and toddlers. All in all, the canonical manifestation is no more representative of emotion regulation than formal operations is representative of cognition. It demands too much development to be the prototype of regulation. We now elaborate briefly on the idea of conflict resolution that we see as central in the canonical instance. The conflict involves two emotions, each of which operates under the same principles we described previously. However, each emotion serves a different goal from the other. For example, a person may have a sexual desire but hold it in check for fear of rejection by the other. The conflict in the canonical instance is complicated by being slow in developing; such instances typically involve a fast-acting, impulsive emotion that requires minimal processing resources and a slower developing emotion reflecting better socialized goals to which the mature self is committed (see Loewenstein, Reed, & Baumeister, 2003). Although the latter typically involves higher moral value, the former, more impulsive emotion can often gain what Frijda (1986) called control precedence. That is, the action tendency becomes strong and strives for immediate execution. However, because emotions intrinsically involve monitoring of anticipated consequences of one’s selecting a response tendency, the emergence of the second, slower activating emotion can result in the inhibition of the impulses despite their lack of initial control precedence. As a result of such monitoring of the consequences of executing a behavioral strategy, the influence of the slower, more cognitively demanding emotion begins slowly to be felt. People thus often find themselves restraining the lower precedence, fast-acting impulse (typically in the voluntary fashion described by Eisenberg & Spinrad, this issue). If this analysis is correct, the canonical instance of emotion regulation can be observed only in older children, adolescents, and adults. It is a form of meta-emotion (Gottman, Katz, & Hooven, 1997), requiring a cognitive capacity to reflect on one’s emotions and, in part, voluntarily decide what to do. Infants and toddlers would not be expected to show much evidence of this type of emotional conflict. The fact that infants and toddlers clearly can regulate their emotions even before having the capacity for meta-emotion shows that the canonical instance is not truly representative of fundamental 386 Campos, Frankel, and Camras emotion-regulation processes. The canonical instance is developmentally a late-onset phenomenon. Therefore, even in this seemingly canonical ‘‘first emotion, then regulation’’ situation, we believe the processes involved continuously reflect the constitutive and regulatory processes that enter into significant transactions with the world. Whatever their relative precedence, both responses (e.g., the urge to hit someone and the deep breath one takes to hold matters in check) are linked to emotion, and both responses are regulated from the outset. Indeed, it can take more regulated care, for example, to steal a tempting object undetected than to walk away from one. Only in a colloquial, introspective sense does it appear that the slower, higher precedence response is regulating the faster, lower precedence impulse that it is supplanting. However, each response option is itself both constitutive and regulatory. That is, each response option reflects construals and goals that are different from each other, yet both construals are constitutive and both goals set regulatory targets. Stealing the coveted object is motivated by positive emotions but also risks negative emotions. Motivated more powerfully to prevent those negative emotions, the person instead counts to 10, is careful not to betray any impulse to steal the object, and then does not steal the object. Developmental Implications We now pose the question that Cole et al. (this issue) posed to themselves: What does the conceptual framework we have elaborated buy us in terms of guiding new research? Elaborating the developmental implications of what we have just proposed about emotion and emotion regulation would require a monograph unto itself. We can at best be selective about developmental implications in what we have described. An Epigenetic Approach to the Development of Emotion and Emotion Regulation Few have speculated on how emotion and emotion regulation develop. At best, we assume that maturational processes account for changes in both, but we rarely test the assumption. Sometimes, cognitive development is given the central role as the major organizer of emotional changes with age, but most approaches merely correlate cognition and emotion in an attempt to identify synchronies in development. At other times, researchers remain agnostic about the underlying processes accounting for the organization of development, leaving behind phenomena in search of explanation. The approach proposed here postulates sets of epigenetic processes that account for the development of emotion and emotion regulation. By epigenesis, we mean only that one developmental acquisition makes possible experiences that lay the stage for new and enduring developmental acquisitions, not that there is a single epigenetic trajectory that all individuals follow. Development of Instrumental Behaviors Affects Emotion and Emotion Regulation The field of emotional development has missed out on the study of several periods of rapid and important developmental transitions in emotion and emotion regulation in the child by not considering the epigenetic consequences of motor development of the infant and young child. We earlier argued that equipotentiality of responses is a hallmark of emotion and emotion regulation. Such equipotentiality must be intrinsically limited at the beginning of life, becoming progressively richer with age as the child develops new means of responding to and dealing with the world. These means include scanning, reaching, crawling, walking, and speaking, which form a generally ordinal series of increasingly complex means of behaving and attaining goals. As each of these skills develops, response options increase in number, and a child’s emotional dealings can become more flexible. If there is any truth to the proposal that the development of instrumental behavior can profoundly affect emotion and emotion regulation, it comes as a surprise to us that so little work has been devoted to understanding how the progressive enrichment of motoric options for the infant and child affects the child’s emotional life. There have been only a scattering of studies of how reaching affects the emotional life of the infant (Witherington, 1998), how crawling reorganizes the infant and family system of interactions (Campos, Kermoian, & Zumbahlen, 1992), how walking influences emotion and emotion regulation (Biringen, Emde, Campos, & Applebaum, 1995), and how language and emotion interact (Bloom, 1993). Only the scanning and head turning behavior of the infant has been investigated with some degree of thoroughness (Field & Fogel, 1982). In short, the increasing voluntarization of the child’s responding (see Eisenberg & Spinrad, this issue) is a major area ripe for exploration. It must constitute a major step (though not the first one) in the development of emotion and emotion regulation and how such processes can go awry. For example, some mothers welcome the onset of crawling as a From Another Perspective: The Nature of Emotion Regulation sign of the baby’s increasing autonomy; others rue it. The different meanings of crawling for different mothers thus must create very different social contexts for the child’s affective life, influencing both social regulation and self-regulation. Developments in Language Affect Emotion and Emotion Regulation Let us consider the importance we have given to emotional communication. A major aspect of such communication is language. We consider language to be both a constitutive and a regulatory process for emotion. It is the means par excellence (although not the only one) by which cultural values are inculcated into the child. It is a major means by which children shift from a demanding or petulant but indistinct expressiveness of what they want to the more specific forms of requesting that a need be met that language affords. Language also facilitates, perhaps even makes possible the beginnings of, the process of negotiation, by which the child and the socializing agents coconstruct a mutually acceptable outcome. The acquisition of language, therefore, must be a major milestone in the study of emotion and emotion regulation. What kinds of studies of emotion and language are there in the literature? We have a modest literature on the acquisition of an emotion lexicon (Bretherton & Beeghly, 1982), studies on how emotion signaling and language influence each other’s development (Bloom, 1993), and investigations of the ways that different cultures construe the nature of emotion by their language usage (Wierzbicka, 1994), yet there are remarkably few studies showing how the acquisition of language affects the organization of emotional development. We therefore call for investigations of how language constitutes emotions by conveying values, including praise, rejection, drawing attention to the emotional reactions of others, and so on. We need to understand how language acquisition and skill helps change how emotions are manifested, and how language communicates some emotions such as scorn or contempt more easily than nonverbal expressions. Language also becomes interiorized, resulting in much better self-regulation, as Luria and Judovich (1956/1959) proposed. In fact, the interiorization of language must be pivotal for personality development and the fantasy world of the child. We need to revisit the work of Luria and others to understand the role of language, expressed openly or interiorized, in emotion and emotion regulation. This paper is a clarion call for studies of how 387 language acquisition affects emotion and emotion regulation (see also Holodinski & Friedlander, in press). Coregulation of Social Signals and Interiorization Processes in the Development of Emotion and Emotion Regulation Another point of entry into developmental transitions in emotion and emotion regulation comes from the study of the differentiation of emotional expressions (or social signals). The studies by Camras (1992) and her colleagues (e.g., see Camras, Oster, Campos, & Bakeman, 2003) have called into question the view that infants produce expressions of discrete negative emotions (e.g., anger, sadness, fear) during the first few months of life. Her work makes clear that we know very little about when facial, vocal, or gestural expressive patterns become adult-like. Camras’s conclusions about the lack of early differentiation of expressions have profound implications for understanding emotion and emotion regulation. To the extent that infants use expressions as a means of influencing their relation to the world (i.e., by influencing others), lack of differentiation of expressions implies that social agents must use a multiplicity of factors (including the infants’ nonfacial body and vocal behaviors) to interpret the infants’ emotion. To the extent that young infants’ nonfacial behaviors are themselves undifferentiated (e.g., because of their limited motor capabilities), social agents must rely on context. Furthermore, undifferentiated facial expressions and bodily reactions may imply a lack of differentiation in infants’ negative emotional experience itself (e.g., they may experience nonspecific distress rather than discrete anger, sadness, etc.). This suggests the possibility raised by Gergely and Watson (1996, 1999) that a form of social biofeedback is essential for the infant or child to construct emotional states, in particular, discrete feelings. Social biofeedback refers to the process wherein the parent, by selectively exaggerating and mirroring the infant’s expressions, helps shape the expressions into more regular patterns and enables the child to match the feedback from his or her emotional expressions to his or her feeling states. Gergely and Watson’s approach is a superb instantiation of the constitutive and regulatory aspects of emotional expressions, and provides a window into understanding how such expressive responses can be used in more complex ways at later ages to help acculturate the child. The study of the development of emotional expressions and their synchrony and coordination with the 388 Campos, Frankel, and Camras expressions of caregivers constitutes a major implication of the model we propose here. Still another implication of our model arises from the fact that early in life, the infant’s emotion and emotion regulation is largely regulated by external agents. This follows from the motoric limitations evident in early life. In those early months, the infant and the caregiver constitute a coregulatory system. However, as the baby develops, that coregulation changes, and eventually the child starts to take increasing control over regulatory processes. This control is evident in a variety of ways, including the child’s beginning use of emotional expressions in a voluntary, intentional, and instrumental fashion (again, see the commentary by Eisenberg & Spinrad, this issue). We have no systematic literature on this important development shift from dyadic coregulation (which in a way, not unlike a Piagetian primary scheme, is never lost with advancing age) to increasingly self-organized deployment of emotional resources. As new cognitive skills (especially symbolic skills) enter into play, emotion and emotion regulation begin to take new forms. In particular, emotion memories become enduring (indeed, a recent study by Hertenstein & Campos, in press, has noted a developmental shift in memory for emotional interactions between 11 and 14 months). The very process of emotion and emotion regulation thus undergoes major developmental changes in the first 15 months of life, and doubtless, these changes forecast major developmental changes to come. For articulate examples of how the development of symbolic processes may affect emotional development, see Mascolo and Fischer (1995) and Mascolo and Harkins (1998). Identifying Preexisting Processes That Affect the Manifestation of Emotion In discussing how emotion regulation plays a role from the very outset of an emotion-inducing episode, we believe we have pointed to an important line of work that needs systematic investigation. We know that a child’s ongoing state powerfully affects his or her reaction to pain. In particular, when the child is in non-rapid-eye-movement sleep (NREM states), pain reactions appear to be minimal compared with painful stimulation encountered during drowsy, waking, or REM states (Porter, 1990). This phenomenon requires further confirmation and extension in age and to other stressors. Another instance of preexisting processes playing a role in emotion and emotion regulation is arousal transfer (Zillman, Katcher, & Milavsky, 1972). A high state of arousal experienced in emotion state A can create a background that adds to the intensity of the experience of emotion state B. For example, the arousal an adult experiences when anger can affect the intensity of that person’s sexual desire. The phenomenon of arousal transfer has not been studied developmentally to the best of our knowledge. However, it is a phenomenon mothers intuitively know well. Mothers realize that a child who is running and laughing gleefully in a vigorous game can quickly shift to extraordinarily intense crying if the child encounters something negative (e.g., falling)Fcrying that would not be so intense if the child had not become so ‘‘worked up’’ by the excited laughing and running. The effects of background state, arousal transfer, and similar phenomena (including Dodge & Pettit’s, 2003, hostile attribution bias) point to the importance not only of studying how preexisting processes influence the generation and intensity of emotional experiences but also how these biases operate differently at different developmental levels of the child. We hope that these examples illustrate sufficiently the heuristic value of the principles we have proposed in this paper and the need to study each of the principles with a developmental point of view. Methodological Implications for the Study of Emotion and Emotion Regulation The Need for an Interpretational Methodology in Preference to an Operationalist Methodology One of the major implications of the model we have presented is methodological. We remind the reader of a pivotal point in the history of the study of socioemotional development. In 1977, the concept of attachment, defined operationally after Bowlby (1969) as physical proximity seeking, began to encounter many difficulties related to the lack of consistency of individual differences expected to be shown across age and contexts. Clearly, physical proximity (measured by physical distance of the child from the caretaker) is a superb indicator of attachment early in life (see Cohen & Campos, 1974). By 18 months, physical proximity seeking is no longer the sensitive indicator of attachment it had once been. When that apparent theoretical inconsistency was noted, the concept of attachment was in danger of being the baby who is thrown out with the bathwater; as disaffection in physical proximity seeking as an operationalization of attachment grew, so did disaffection with the construct of attachment. From Another Perspective: The Nature of Emotion Regulation In one of the most important papers written in the study of emotion, Sroufe and Waters (1977) argued for an approach that did justice to the meaning of behavior and that permitted taking into account alternative manifestations of the proximity-seeking hallmark of attachment. They noted how a child could show security in the presence of the parent in many ways, and coders thus had to be sensitive to the organization of behavior, to the possibility that different behaviors could be in the service of the same function of attaining felt security (e.g., a child could show social referencing or a pickup bidFconsidered as alternative means of seeking contact with the motherFwhile not showing any change in physical proximity). Sroufe and Waters provided evidence that taking an organizational, interpretational approach to the behaviors of infants in the Strange Situation revealed unexpectedly strong continuities in the classification of infants as secure, avoidant, or ambivalent. Few can argue with the success of the recommendations of Sroufe and Waters, which led the study of attachment to become the dominant approach in socioemotional development over the past quarter century. We believe that a similar approach is called for in the study of emotion and emotion regulation. Like Sroufe and Waters (1977), we call for the study of patterns of behavior and behavior interpreted in context as the appropriate first step in the study of emotion (Camras, et al., 2002). A similar call was made long ago by Miller and Sperry (1987), who noted the many advantages of the study of narratives, as was the eloquent appeal by Jessor (1996) for the importance of ethnographic methods in the study of human development. Our methods must do justice to the meaning of behavior to be effective in revealing important findings about emotion and emotion regulation. The Proper Role of Experimentation and Operationalization Our recommendation does not imply that we should abandon experimentation and careful quantification of objectively specified expressive, instrumental, or physiological responses. Rather, we are proposing that such standard experimental methods not be the de facto standard or the default method for empirical research in the study of emotion and emotion regulation. The merits of experimentation and objective quantification must be weighed against the strict constraints such methods place on the generalization and ecological validity of findings using such methods. At the least, converging research methods that combine experimentation with 389 confirmatory ethnographic reports of behaviors in the real world need to be considered. Coherence or Equifinality in Measuring Emotion and Emotion Regulation? A second methodological implication of the approach we are proposing is to challenge research approaches that search for the coherence of emotional behaviorFthat look for moderate to high correlations among dependent indexes of emotion. The commitment to coherence of responses is strong in the field. That commitment may be an atavism of psychology’s quest for a general factor in psychological processes such as intelligence, or the desire to confirm the presence of a general factor such as arousal in measures of emotion (Duffy, 1962), or a misunderstanding of the principle of converging research operations (Garner, Hake, & Erickson, 1956). Whatever the reason, researchers typically feel most comfortable making inferences about emotion when behavior, physiology, and, where appropriate, self-report cohere (see Cole et al.’s point in the lead article, this issue). But coherence in emotion measures may be a holy grail not to be found. We believe that, more often than not, emotion and emotion regulation are evident in the selection of one behavior pattern over another, that is, in the equifinality of different responses and not in their coherence. Let us take studies of infant behavior on the visual cliff as an example. Coherence of emotional behaviors is a rarity in such studies, despite the fact that the cliff is widely considered to be one of the strongest elicitors of fear in the human infant (Scarr & Salapatek, 1970). Let us consider three typical behavior patterns seen in tests on the visual cliff to demonstrate how coherence of indexes of fear is lacking while the observer clearly infers the presence of fear or wariness. Most tests on the visual cliff involve determining whether the infant will cross to the mother over the deep side of the cliff or not. One prototypical pattern shown by infants beyond a certain age and experience locomoting is one of complete reluctance to cross the deep side and, indeed, a backing away from the apparent drop-off. At the precise moment the infant is avoiding crossing the cliff, the infant is likely to be smiling. Smiling and avoidance should not go together in a fear state, but they do. Which index should we trustFthe moving away from the edge or the smiling of the baby? There is a second pattern observed in some 20% of infants from which one can infer fear or wariness. An alternative to avoidance of crossing the deep side at 390 Campos, Frankel, and Camras all is what we have called detour crossing, wherein the infant will not cross over the deep side to the mother on a beeline but will cross to the mother by holding onto the side wall of the cliff and tiptoeing on the thin shelf that supports the safety glass until the baby reaches her. This alternative behavior is typically not accompanied by smiling; therefore, successful resolution of a conflict by the detour does not cohere with facial expressions expected with successful problem solving. The third pattern of behavior on the cliff is evident when infants are tested slightly differently on the cliff: When the infant is placed directly atop the cliff, the child shows intense emotional expressions and freezing rather than avoidance; smiling is never observed and rarely is avoidance or escape. Therefore, one pattern involves avoidance and smiling, the second involves approach via detour but no smiling, and the third involves neither avoidance nor approach and no smiling. Facial movements of distress are typically seen only in the third case. Given these patterns of behavior on the cliff, correlations among indexes of emotion in any single visual cliff study will necessarily be low and thus not coherent. They are not what is expected by most researchers in emotion when dealing with intense emotional states. Yet, despite the lack of coherence observed in visual cliff tests, no observer escapes the conclusion that strong emotion has been elicited by the virtual dropoff. We believe the inescapability of the conclusion comes from the recognition of functional equifinality of the infant’s attempts to prevent harm, despite the variation (equipotentiality) in emotional responding in this context. We thus conclude that coherence of behavior is neither typical nor expectable in studies of emotion, even under conditions of intense negative transactions. Rather, there are patterns of alternative manifestations of emotional behavior in any emotional encounter. This principle of equipotentiality of responses in the service of equifinality of outcome will surely apply even more robustly to less intense emotional transactions than settings such as the visual cliff. Affective Neuroscience and Its Relation to Emotion and Emotion Regulation Many researchers have marshaled substantial amounts of evidence from the findings of affective neuroscience (see especially the commentaries in this issue by Bell & Wolfe; Goldsmith & Davidson; Lewis & Stieben). Researchers universally recognize the extraordinary promise of this new approach to in- quiry into emotion and its regulation (for an excellent, accessible primer, see Brett, Johnsrude, & Owen, 2002). However, affective neuroscience is clearly a nascent field, as Goldsmith and Davidson (this issue) remarked unequivocally, and is furthermore one with extraordinarily serious and, in some cases, intractable technological problems. These problems limit its ability to shed light on the processes involved in emotion and emotion regulation. We thus think it appropriate to offer a coda on affective neuroscience to this section on methodology. Contrast affective neuroscience with the bases for progress in the more established neuroscience of vision. Both sensory psychophysics and visual perception have found numerous phenomena that show strong mathematically specifiable relations between physical stimulation and psychological statesFrelations that are robust within and across individual human beings and across mammalian species. Moreover, the components of visual stimulation can be identifiedFedges, color, size, orientation, motion, depth, and many more. Most of these features can be specified geometrically, both in the physical world and in their projection as light onto membranes such as the retina. These discrete features can be experimentally manipulated to determine whether it is a component of the pattern of stimulation, or the pattern itself, that elicits the sensory experience or the percept. Furthermore, singlecell recording, animal models, lesion studies, and data from functional magnetic resonance imaging (fMRI) have been used as converging research operations to provide substantial confidence that relations exist among environmental stimulation, visual perception, and specific aspects of brain function. By contrast, affectogenic stimuli, such as the International Affective Picture System (Center for the Study of Emotion and Attention, 1994) or film clips chosen to induce emotions (Gross & Levenson, 1995), are not nearly so regular in their stimulus – response relations as are the relations (let us say) between frequencies of light and experience of color, or binocular stimulation and stereoscopic vision. In studies conducted in affective neuroscience, the same person can have different emotional responses to a given elicitor in different contexts on the same day, or even in a single experimental situation that places different task demands on the participant (Lange et al., 2003). Affectogenic stimuli are not easily broken down into component features that can be varied separately to ensure that it is the emotional quality of the transaction and not some simple physical difference residing in contrasting stimuli that accounts for the differences in brain activation. For example, varying the number From Another Perspective: The Nature of Emotion Regulation of cute, fuzzy animals depicted in a slide may not have the utility for affective science that varying the amount of color saturation has for vision science. Rat and primate models of emotion do not readily or necessarily generalize to other species. Lesion data, both within species and across species, are much more ambiguous for emotion than for vision. A region of interest for emotion research, the frontal cortex (FC), is the most irregular of gray matter structures, making localization of FC function unreliable. For these reasons, differential emotional activation of brain regions can neither be produced nor interpreted with the precision of visual neuroscience. The instruments also impose limitations. The newest instrument, fMRI, offers better spatial and temporal resolution than positron emission tomography (PET) and incomparably better spatial resolution and completeness than either electroencephalography (EEG) or magnetoencephalography (MEG). Even so, yielding several orders of magnitude fewer voxels than the brain has neurons, fMRI spatial resolution is coarse. For instrumentation of real-time processes such as emotion and its regulation, the temporal resolution of fMRI is seriously limited, both in the sampling rates that are feasible and in the low differentiation of hemodynamic response to closely sequenced events. Also, both EEG and fMRI data are easily made uninterpretable by movement, requiring experimental situations where participants’ movement is largely prevented. EEG and fMRI thus record the emotions of a research participant who is in reality an audience, watching events presumed to be emotional in a narrowly constrained slide show or on the ‘‘screen’’ of his or her memory. The methods used in affective neuroscience are not yet mature enough to characterize the family of real-time constitutive and regulatory processes in emotion and emotional regulation Fprocesses that, having much greater equipotentiality than vision, are much harder to study. It is not surprising that preliminary findings are mixed. For example, in a recent meta-analysis of more than 50 whole-brain fMRI studies for affective stimuli with respect to 22 brain regions, Phan, Wager, Taylor, and Liberzon (2002) determined that only the relation between the amygdala and fear was found in more that 50% of studies, and activation of the insula co-occurred with sadness in more than 40% of studies. All other localities occurred less frequently in both cortical and subcortical regions reviewed. This level of replication is lower than is typical in the neuroscience of basic visual functionsFlow enough to demand caution in drawing inferences about brain – behavior relations in affect. (Imagine, in the 391 clinical literature, touting a change in standard of care, based on a 40% meta-analytic showing for a new treatment.) We are starting to learn what brain regions might be differentially implicated in different emotions. However, we know so little about the contributions of the regions implicated in affect that we cannot begin to decide whether emotion has locality in the brain or if emotion is an emergent property of other kinds of functional activations, such as the orchestration of different regions of the brain. A trustworthy map of the brain regions implicated in emotion and what they do, individually and in interaction, is still far away. In sum, the contributions to this special issue, along with our own reading of the literature, reveal three important features of affective neuroscience: (a) there is an impressive capacity to start ‘‘lifting up the skull’’ and to study brain structure and function; (b) affective neuroscience is not yet strong enough or replicable enough to be used to explain much about real-life emotional phenomena, especially in early life; and (c) reports and interpretations in affective neuroscience are sometimes expressed with excessive confidence, in light of the limitations of the instruments and the stimuli, and questionable internal and external validity of the experimental paradigms. Despite the seductive attractiveness of unprecedented forms of instrumentation that promise to move toward hard science, affective neuroscience is not yet close to the consensual bases for confidence of demonstration that is typical of hard sciences. Conclusion In summary, we have proposed that emotion and emotion regulation are not two separate phenomena but are different facets of a single set of processes. We use the term emotion to stand for the meaning of a transaction between a person and an event, including what, in general, a person can do about the transaction. We use the term emotion regulation to refer to the variations in what a person can do depending on different contexts. The two words, while conceptually distinguishable, have the same referentFdealing with a person – environment problem. Emotion and emotion regulation involve equipotentiality of responding to the world in the service of promoting equifinal outcomes, rendering operational definitions problematic and identification of the goal of the behavior essential. Future research needs to look at emotion and emotion regulation as well as their development from a very different vantage point than has been the case and to use methods that do justice to the meanings, goal 392 Campos, Frankel, and Camras relevant and otherwise, that produce, reside in, and guide emotional behavior. Emotions are not good or bad, in and of themselves, except when context makes them so. We believe there is ample historical precedent for these ideas. Their roots can be traced at least to Aristotle, who instantiated emotion and emotion regulation well in this quote from his Nicomachean Ethics: ‘‘The person who is angry at the right things and toward the right people and also in the right way, at the right time, and for the right length of time, is praised’’ (1999, p. 61). The rub for the study of emotion and emotion regulation is in the use of the word right. What has made the study of emotion and emotion regulation extraordinarily difficult and confusing is neglecting, from the outset, to partition the question of suitability of goalsFthe rightness of goalsFfrom the question of adequacy of goal accomplishmentFthe rightness of the constitutive and regulatory processes that activate and accomplish goals in response to events, whatever a person’s goals and whatever their suitability.
