Emotions as guardians of group norms: expressions of anger and disgust drive inferences about autonomy and purity violations.

Other people's emotional reactions to a third person's behaviour are potentially informative about what is appropriate within a given situation. We investigated whether and how observers' inferences of such injunctive norms are shaped by expressions of anger and disgust. Building on the moral emotions literature, we hypothesised that angry and disgusted expressions produce relative differences in the strength of autonomy-based versus purity-based norm inferences. We report three studies (plus three supplementary studies) using different types of stimuli (vignette-based, video clips) to investigate how emotional reactions shape norms about potential norm violations (eating snacks, drinking alcohol), and contexts (groups of friends, a university, a company). Consistent with our theoretical argument, the results indicate that observers use others' emotional reactions not only to infer whether a particular behaviour is inappropriate, but also why it is inappropriate: because it primarily violates autonomy standards (as suggested relatively more strongly by expressions of anger) or purity standards (as suggested relatively more strongly by expressions of disgust). We conclude that the social functionality of emotions in groups extends to shaping norms based on moral standards.

Emotion and the construal of social situations: inferences of cooperation versus competition from expressions of anger, happiness, and disappointment.

The notion that emotional expressions regulate social life by providing information is gaining popularity. Prior research on the effects of emotional expressions on observers' inferential processes has focused mostly on inferences regarding the personality traits of the expresser, such as dominance and affiliation. We extend this line of research by exploring the possibility that emotional expressions shape observers' construal of social situations. Across three vignette studies, an interaction partner's expressions of anger, compared to expressions of happiness or disappointment, led observers to construe hypothetical situations as less cooperative, both in dyads and groups. These effects occurred even when factual information regarding the cooperativeness or competitiveness of the situation was provided, attesting to the power of emotional expressions in shaping the construal of social situations. Results are discussed in relation to appraisal theory, reverse appraisals, emotions as social information theory, and the emergence of cooperation in groups and cultures.

Deriving meaning from others' emotions: attribution, appraisal, and the use of emotions as social information.

Emotional expressions constitute a rich source of information. Integrating theorizing on attribution, appraisal processes, and the use of emotions as social information, we examined how emotional expressions influence attributions of agency and responsibility under conditions of ambiguity. Three vignette studies involving different scenarios indicate that participants used information about others' emotional expressions to make sense of ambiguous social situations. Expressions of regret fueled inferences that the expresser was responsible for an adverse situation, whereas expressions of anger fueled inferences that someone else was responsible. Also, expressions of anger were interpreted as a sign of injustice, and expressions of disappointment increased prosocial intentions (i.e., to help the expresser). The results show that emotional expressions can help people understand ambiguous social situations by informing attributions that correspond with each emotion's associated appraisal structures. The findings advance understanding of the ways in which emotional expressions help individuals understand and coordinate social life.

How instructors' emotional expressions shape students' learning performance: the roles of anger, happiness, and regulatory focus.

How do instructors' emotional expressions influence students' learning performance? Scholars and practitioners alike have emphasized the importance of positive, nurturing emotions for successful learning. However, teachers may sometimes lose their temper and express anger at their pupils. Drawing on emotions as social information (EASI) theory, we hypothesized that expressions of anger can benefit learning performance. In Experiment 1, participants who were confronted with an angry instructor exhibited more accurate recognition of word pairs after a week of learning, compared with those who were confronted with a happy instructor. In Experiment 2, we conceptually replicated this effect on a recall task, but only among participants in a promotion rather than prevention focus. Present findings thus show, for the 1st time, that instructor anger can enhance students' performance. Findings are consistent with a conceptualization of emotion as social information and call into question the generally endorsed positivity paradigm.
