Emotional ties that bind: the roles of valence and consistency of group emotion in inferences of cohesiveness and common fate

In three studies, observers based inferences about the cohesiveness and common fate of groups on the emotions expressed by group members. The valence of expressions affected cohesiveness inferences, whereas the consistency of expressions affected inferences of whether members have common fate. These emotion composition effects were stronger than those due to the race or sex composition of the group. Furthermore, the authors show that emotion valence and consistency are differentially involved in judgments about the degree to which the group as a whole was responsible for group performance. Finally, it is demonstrated that valence-cohesiveness effects are mediated by inferences of interpersonal liking and that consistency-common fate effects are mediated by inferences of psychological similarity. These findings have implications for the literature on entitativity and regarding the function of emotions in social contexts.     

The social signal value of emotions

Human interactions are replete with emotional exchanges. In these exchanges information about the emotional state of the interaction partners is only one type of information conveyed. In addition, emotion displays provide information about the interaction partners' disposition and the situation as such. That is, emotions serve as social signals. Acknowledging this role of emotions, this special section brings together research that illustrates how both person perception and situational understanding can be derived from emotional displays and the modulation of this process through context. Three contributions focus on information about expressers and their intentions. An additional article focuses on the informative value of emotional expressions for an observer's construal of social situations and another article exemplifies the way context determines the social impact of emotions. Finally, the last article presents the dynamic nature of mutual influence of emotions. In an attempt to integrate these contributions and offer lenses for future research, this editorial offers a contextualised model of social perception which attempts to systematise not only the types of information that emotion expressions can convey, but also to elaborate the notion of context.     

Affective expressions in groups and inferences about members' relational well-being: The effects of socially engaging and disengaging emotions

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions—the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance.     

Assessing the way people look to judge their intentions

Faces of unknown persons are processed to infer the intentions of these persons not only when they depict full-blown emotions, but also at rest, or when these faces do not signal any strong feelings. We explored the brain processes involved in these inferences to test whether they are similar to those found when judging full-blown emotions. We recorded the event-related brain potentials (ERPs) elicited by faces of unknown persons who, when they were photographed, were not asked to adopt any particular expression. During the ERP recording, participants had to decide whether each face appeared to be that of a positively, negatively, ambiguously, or neutrally intentioned person. The early posterior negativity, the EPN, was found smaller for neutrally categorized faces than for the other faces, suggesting that the automatic processes it indexes are similar to those evoked by full-blown expressions and thus that these processes might be involved in the decoding of intentions. In contrast, in the same 200-400 ms time window, ERPs were not more negative at anterior sites for neutrally intentioned faces. Second, the peaks of the late positive potentials (LPPs) maximal at parietal sites around 700 ms postonset were not significantly smaller for neutrally intentioned faces. Third, the slow positive waves that followed the LPP were larger for faces that took more time to categorize, that is, for ambiguously intentioned faces. These three series of unexpected results may indicate processes similar to those triggered by full-blown emotions studies, but they question the characteristics of these processes.     

Seeing what you ought to see: The role of contextual factors in the social perception of achievement emotions

To assess the impact of context information on emotion perception, participants saw a picture of a male or female person with either a neutral, happy or sad facial expression and received information about the context in which the picture was taken. Their task was to rate the emotion actually expressed in the photo (i.e., focal emotions) as well as emotions not actually expressed (i.e., non-focal emotions) and inferences extracted from them. We predicted and found that context information affected both the perception of emotions and the inferences that the observers drew from them. Perceivers used context information in order to make sense of what was perceived to the extent that in the case of neutral expressions and for non-focal emotions, they “see” things that do not actually exist.     

Emotional expressions forecast approach-avoidance behavior

The contention that basic behavioral intentions are forecasted by emotional expressions has received surprisingly little empirical support. We introduce a behavioral task that gauges the speed with which movement of angry and fearful faces (toward or away from an expressor's gaze) are accurately detected. In two studies we found that perceivers were faster to correctly detect approaching anger faces (i.e., faces that moved in the direction of their own gaze). The opposite, however, was not true for fear expressions. These findings offer evidence that, at least for anger displays, the basic behavioral intent to approach is strongly transmitted and at very low-levels of processing, even priming congruent behavioral responses in observers. The null results for fear faces may indicate that these signal a “freezing” response or behavioral inhibition rather than flight per se. The results of this work are discussed in relation to contemporary theories of emotion.     

Recognition of emotion from inverted schematic drawings of faces

The present study investigated whether facial expressions of emotion are recognized holistically, i.e., all at once as an entire unit, as faces are or featurally as other nonface stimuli. Evidence for holistic processing of faces comes from a reliable decrement in recognition performance when faces are presented inverted rather than upright. If emotion is recognized holistically, then recognition of facial expressions of emotion should be impaired by inversion. To test this, participants were shown schematic drawings of faces showing one of six emotions (surprise, sadness, anger, happiness, disgust, and fear) in either an upright or inverted orientation and were asked to indicate the emotion depicted. Participants were more accurate in the upright than in the inverted orientation, providing evidence in support of holistic recognition of facial emotion. Because recognition of facial expressions of emotion is important in social relationships, this research may have implications for treatment of some social disorders.     

What do facial expressions convey: feeling states,behavioral intentions,or action requests?

Emotion theorists assume certain facial displays to convey information about the expresser's emotional state. In contrast, behavioral ecologists assume them to indicate behavioral intentions or action requests. To test these contrasting positions, over 2,000 online participants were presented with facial expressions and asked what they revealed-feeling states, behavioral intentions, or action requests. The majority of the observers chose feeling states as the message of facial expressions of disgust, fear, sadness, happiness, and surprise, supporting the emotions view. Only the anger display tended to elicit more choices of behavioral intention or action request, partially supporting the behavioral ecology view. The results support the view that facial expressions communicate emotions, with emotions being multicomponential phenomena that comprise feelings, intentions, and wishes.     

基本情绪的神经基础：来自fMRI与机器视觉技术研究的证据

基本情绪理论(basic emotion theory)是情绪科学领域最具代表性的理论, 该理论认为人类情绪是由有限的几种基本情绪组成的, 如恐惧、愤怒、喜悦、悲伤等。基本情绪是为了完成基本生命任务(fundamental life task)进化而来的, 每一种基本情绪都有独特的神经结构和生理基础。尽管基本情绪理论被广泛接受, 但是对于基本情绪的种类却莫衷一是。近几十年来, 许多fMRI研究试图确定各种基本情绪的独特神经结构基础, 而且取得了许多重要发现, 比如厌恶和脑岛有关, 悲伤和前扣带回有关, 杏仁核是与恐惧有关的重要边缘结构等。但是, 最近有人进行了元分析研究, 发现许多基本情绪存在混淆的大脑区域, 因此对基本情绪的特定脑区理论提出质疑, 甚至否定基本情绪理论。通过对基本情绪及其神经基础的探讨, 以及对基本情绪理论的最新功能性磁共振成像研究进行梳理分析, 提出有关基本情绪理论的争论来源于基本情绪种类的确定, 因为许多所谓的不同基本情绪实际上是同一种基本情绪, 提出人类可能只有3种基本情绪。未来研究可以利用机器视觉技术进一步推动基本情绪脑影像研究。     

Do Dynamic Facial Expressions Convey Emotions to Children Better Than Do Static Ones?

Past research has shown that children recognize emotions from facial expressions poorly and improve only gradually with age, but the stimuli in such studies have been static faces. Because dynamic faces include more information, it may well be that children more readily recognize emotions from dynamic facial expressions. The current study of children (N = 64, aged 5–10 years old) who freely labeled the emotion conveyed by static and dynamic facial expressions found no advantage of dynamic over static expressions; in fact, reliable differences favored static expressions. An alternative explanation of gradual improvement with age is that children's emotional categories change during development from a small number of broad emotion categories to a larger number of narrower categories—a pattern found here with both static and dynamic expressions.

Effects of direct and averted gaze on the perception of facially communicated emotion

Research has largely neglected the effects of gaze direction cues on the perception of facial expressions of emotion. It was hypothesized that when gaze direction matches the underlying behavioral intent (approach-avoidance) communicated by an emotional expression, the perception of that emotion would be enhanced (i.e., shared signal hypothesis). Specifically, the authors expected that (a) direct gaze would enhance the perception of approach-oriented emotions (anger and joy) and (b) averted eye gaze would enhance the perception of avoidance-oriented emotions (fear and sadness). Three studies supported this hypothesis. Study 1 examined emotional trait attributions made to neutral faces. Study 2 examined ratings of ambiguous facial blends of anger and fear. Study 3 examined the influence of gaze on the perception of highly prototypical expressions.     

Emotion Regulation in Adulthood: Timing Is Everything

Emotions seem to come and go as they please. However, we actually hold considerable sway over our emotions: We influence which emotions we have and how we experience and express these emotions. The process model of emotion regulation described here suggests that how we regulate our emotions matters. Regulatory strategies that act early in the emotion-generative process should have quite different outcomes than strategies that act later. This review focuses on two widely used strategies for down-regulating emotion. The first, reappraisal, comes early in the emotion-generative process. It consists of changing how we think about a situation in order to decrease its emotional impact. The second, suppression, comes later in the emotion-generative process. It involves inhibiting the outward signs of emotion. Theory and research suggest that reappraisal is more effective than suppression. Reappraisal decreases the experience and behavioral expression of emotion, and has no impact on memory. By contrast, suppression decreases behavioral expression, but fails to decrease the experience of emotion, and actually impairs memory. Suppression also increases physiological responding in both the suppressors and their social partners.     

Facial morphology and children's categorization of facial expressions of emotions: a comparison between Asian and Caucasian faces

The effects of Asian and Caucasian facial morphology were examined by having Canadian children categorize pictures of facial expressions of basic emotions. The pictures were selected from the Japanese and Caucasian Facial Expressions of Emotion set developed by D. Matsumoto and P. Ekman (1989). Sixty children between the ages of 5 and 10 years were presented with short stories and an array of facial expressions, and were asked to point to the expression that best depicted the specific emotion experienced by the characters. The results indicated that expressions of fear and surprise were better categorized from Asian faces, whereas expressions of disgust were better categorized from Caucasian faces. These differences originated in some specific confusions between expressions.

Similarities and Variations in Facial Expressions of Emotions: Cross-cultural Evidence

North American (Canadian) and Indian observers were shown photographs of six facial emotions; happiness, sadness, fear, anger, surprise, and disgust, expressed by American Caucasian and Indian subjects. Observers were asked to judge each photograph, on a 7-point scale, for the degree of (a) distinctiveness (free from blending with other emotion categories), (b) pleasantness-unpleasantness, and (c) arousal-nonarousal of expressed facial emotion. The results showed significant interaction of Observer × Expressor × Emotion for the distinctiveness judgement. It was found that fearful and angry expressions in Indian faces, in comparison to Caucasian faces, were judged as less distinctly identifiable by observers of both cultural origins. Indian observers rated these two emotion expressions as being more distinctive than did North Americans irrespective of the culture of the expressor. In addition, Indian observers judged fearful and angry expressions as more unpleasant than did North Americans. Caucasians, in comparison to Indians, were judged to have more arousal in most of the emotion expressions.     

The Emerging View of Emotion as Social Information

Emotions play an important role in coordinating social life. In the last decade, traditional research on the intrapersonal effects of emotions has been complemented by a growing focus on interpersonal effects. I propose that a primary function of emotion at this interpersonal level is to disambiguate social interaction by providing information about the expresser’s feelings, goals, motives, and intentions. Building on this idea, I introduce the emotions as social information (EASI) model. The model posits that emotional expressions influence observers by eliciting affective reactions in them and/or by triggering inferential processes, depending on the observer’s information processing motivation and ability and on social-contextual factors. I discuss implications of this view for theorizing about the social functions of emotions; the evolution of emotion; the influence of emotional expressivity, emotion recognition, and emotion regulation; and the role of culture.     

Attending to emotional expressions: no evidence for automatic capture in the dot-probe task

Research on automatic attention to emotional faces offers mixed results. Therefore we examined validity effects for facial expressions of different emotions (compared to neutral faces) with a dot-probe paradigm in seven studies (total N?=?308). Systematic variations of type of emotion, CTI, task, cue size, and masking allow for a differentiated assessment of attentional capture by emotions and possible moderating factors. Results indicate a general absence of emotional validity effects as well as a lack of significant interactions with either of the manipulated factors, indicating that facial expressions of emotions do not capture attention in a fully automatic fashion. These findings suggest that situational and contextual factors have to be taken into account when investigating attentional capture of emotional faces.
