Shame in Response to Affective Expression and Its Relation to Social Anhedonia and Schizotypy Traits

Social Anhedonia and Intergroup Processes: A Multi-Study Investigation of Known and Novel Group Memberships

Introduction: Group memberships play an important role in promoting psychological well-being and supporting social functioning. However, studies suggest that individuals with social anhedonia, a characteristic defined by limited pleasure from social bonds, may show abnormalities in their desire to cultivate positive feelings, such as belongingness, from social groups. Still, these abnormalities have not been studied in the context of intergroup processes, leaving the relation between social anhedonia and subjective evaluations of group memberships unclear. Methods: Across three studies (Ns = 124-659), we examined associations between social anhedonia and affective and cognitive attitudes about different types of ingroups and outgroups using self-report and behavioral measures. Results: Taken together, results indicate that social anhedonia is associated with less positive and more negative feelings and beliefs about most ingroups and outgroups from everyday life, as well as negatively biased stereotyping of many prominent social groups. At the same time, individuals with either extremely high or low levels of social anhedonia did not report significantly different intergroup attitudes when group memberships were experimentally manipulated in a minimal group setting. Discussion: Overall, these findings suggest that social anhedonia is associated with less positive and more negative subjective evaluations of long-established, real-world ingroups, but not of a newly formed ingroup that requires little motivation or social engagement to maintain group membership. Aberrant feelings and attitudes toward one's ingroups are consistent with the theory that social anhedonia is related to anomalies in the need to belong within social groups from everyday life and could inform psychosocial interventions for related psychopathologies.
