The study examined the relationships between out-group perception, perceived intergroup conflict, emotions, and concern for out-group victims in the context of the Japanese earthquake of 2011. Six hundred and eighty-six participants in China completed a questionnaire immediately after the earthquake. Results showed that the image of Japan and historical conflicts between the two nations signifi...

This experiment investigated potential gender biases in the emergence of leadership in groups. Teams played a public-goods game under conditions of intra- or intergroup competition. We predicted and found a strong preference for female leaders during intragroup competition and male leaders during intergroup competition. Furthermore, during intragroup competition, a female leader was more instru...

A method for determination of ab initio group model potentials, with the intention of describing the effects of a whole molecule or a chemical group within a density functional theory framework, is reported. The one-electron part of the Kohn–Sham equations is modified by incorporation of a Coulomb operator, which accounts for the classical electron interaction arising from the group. Exchange a...

Three studies tested the idea that when social identity is salient, group-based appraisals elicit specific emotions and action tendencies toward out-groups. Participants' group memberships were made salient and the collective support apparently enjoyed by the in-group was measured or manipulated. The authors then measured anger and fear (Studies 1 and 2) and anger and contempt (Study 3), as wel...

Perceptions of intergroup threat have been related to both experiences of physiological stress responses and derogation of the outgroup. In this study, a neuroscience perspective was used to investigate the relationship between stress and opportunity to derogate the outgroup, in a threatening intergroup context. Research from a social identity perspective suggests that engaging in outgroup dero...

Intergroup interactions are often anxiety provoking, and this can lead members of both majority and minority groups to avoid contact. Whereas negative consequences of experiencing intergroup anxiety are well documented, the role of perceived anxiety has received substantially less theoretical and empirical attention. We demonstrate in 3 experiments that the perception of anxiety in others can u...

Results of 4 experiments demonstrated that under in-group image threat collective narcissism predicts retaliatory intergroup hostility. Under in-group criticism (vs. praise) collective narcissists expressed intention to harm the offending out-group but not other, nonoffending out-groups. This effect was specific to collective narcissism and was replicated in studies that accounted for the overl...

Two studies used random sample surveys to test the “contact hypothesis” on intergroup attitudes of Catholics and Protestants in Northern Ireland. In Study 1, archival data from two different surveys in 1989 (N = 310 Catholics, 422 Protestants) and 1991 (N = 319 Catholics, 478 Protestants) showed that contact was positively related to attitudes toward denominational mixing. Study 2 (N = 391 Cath...
