Although convergence in emotion expressions within small groups is well documented, the motives that explain why members converge are rarely explicated. We approach expressive convergence from a conformity perspective and introduce the Emotional Conformity Framework, in which we posit that members match their groupmates’ emotion expressions because...

There is a growing consensus that culture influences the perception of facial expressions of emotion. However, relatively few studies have examined whether and how culture shapes the production of emotional facial expressions. Drawing on prior work on cultural differences in communication styles, we tested the prediction that people from the Nether...

Emotional expressions play an important role in coordinating social interaction. We review research on two critical processes that underlie such coordination: (1) perceiving emotions from emotion expressions and (2) drawing inferences from perceived emotions. Broad evidence indicates that (a) observers can accurately perceive emotions from a person...

There is a growing consensus that culture influences the perception of facial expressions of emotion. However, little is known about whether and how culture shapes the production of emotional facial expressions, and even less so about whether culture differentially shapes the production of posed versus spontaneous expressions. Drawing on prior work...

Risk-taking can fuel innovation and growth, but it can also have devastating consequences for individuals and organizations. Here we examine whether risk-taking affords social-hierarchical benefits to risk-takers. Specifically, we investigate how risk-taking influences perceived dominance, prestige, and the willingness to endorse risk-takers' leade...

The rise of the Internet and social media has allowed individuals with different backgrounds, experiences, and opinions to communicate with one another in an open and largely unstructured way. One important question is whether the nature of online engagements between groups relates to the nature of encounters between these groups in the real world....

Past research suggests that the connection between values and people's behaviour may not be as straightforward and robust as has been claimed. We propose that a more holistic and discriminative view that acknowledges the influence of a specific combination of values on specific kinds of behaviour is needed. In the current project, we test two hypot...

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 disg...

Groups are a natural breeding ground for emotions. Group life affords unique opportunities but also poses critical challenges that may arouse emotional reactions in group members. Social-functional approaches hold that these emotions in turn contribute to group functioning by prompting group members to address concerns that are relevant to the grou...

Members of small groups in contexts as varied as sport (Totterdell, 2000), education (Delvaux, Vanbeselaere, & Mesquita, 2015), and work (Totterdell, Kellett, Teuchmann, & Briner, 1998) show convergence in their affective responding towards specific events and objects. Such collective emotions (von Scheve & Ismer, 2013), in turn, influence groups'...

Sports games are inherently emotional situations, but surprisingly little is known about the social consequences of these emotions. We examined the interpersonal effects of emotional expressions in professional baseball. Specifically, we investigated whether pitchers’ facial displays influence how pitches are assessed and responded to. Using footag...

Despite a long-standing interest in the intrapersonal role of affect in persuasion, the interpersonal effects of emotions on persuasion remain poorly understood—how do one person’s emotional expressions shape others’ attitudes? Drawing on emotions as social information (EASI) theory (Van Kleef, 2009), we hypothesized that people use the emotional e...

How many members of a group need to express their anger in order to influence a deviant group member’s behavior? In two studies, we examine whether an increase in number of angry group members affects the extent to which a deviant individual feels rejected, and we investigate downstream effects on conformity. We show that each additional angry reac...

Inclusion in social groups is vital to human survival and wellbeing. We propose that emotional expressions signal acceptance versus rejection to observers. Based on this idea, we hypothesized that happy facial expressions prime acceptance, whereas angry expressions prime rejection. In six experiments using the Affect Misattribution Paradigm (Payne,...

Feeling empathy for a member of the group may result in either favoring this individual at the expense of the group or helping the entire group. We explain these intriguing find- ings by proposing that the combined influence of feeling empathy for one individual and awareness of others enhances willingness to help both the individual and the others (...

How do emotional expressions of group members shape conformity versus deviance in groups? We hypothesized that angry and happy responses to a group member's deviating opinion are interpreted as signals of imminent rejection versus acceptance. In 5 studies, the majority's expressions of anger led the deviant individual to feel rejected, whereas expr...

The question of what makes people rise to power has long puzzled social scientists. Here we examined the novel hypothesis that power is afforded to individuals who exhibit prosocial norm violations—i.e., breaking rules for the benefit of others. Three experiments using different methods provide support for this idea. Individuals who deliberately ig...

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 b...

Functional approaches to emotion are rapidly gaining in popularity. Thus far the functions of emotions have been conceptualised and studied mainly at the intrapersonal level of analysis, the key question being how individuals are influenced by the emotions they experience. Relatively little is known about the interpersonal effects of emotions; that...
