Two experiments provide initial evidence that specific emotional states are capable of creating automatic prejudice toward outgroups. Specifically, we propose that anger should influence automatic evaluations of outgroups because of its functional relevance to intergroup conflict and competition, whereas other negative emotions less relevant to intergroup relations (e.g., sadness) should not. I...

Trust and cooperation often break down across group boundaries, contributing to pernicious consequences, from polarized political structures to intractable conflict. As such, addressing such conflicts require first understanding why trust is reduced in intergroup settings. Here, we clarify the structure of intergroup trust using neuroscientific and behavioral methods. We found that trusting ing...

Previous gaze-cuing studies found that intergroup threat is one of the modulators of gaze cuing. These findings indicate that intergroup threat would gate social attention by activating a network resembling that is thought to be involved in drawing or/and holding attention. The present study tested this hypothesis using a gaze-cuing task in which a particular in-group participants observed thre...

Previous research has shown that (a) positive intergroup contact with an advantaged group can discourage collective action among disadvantaged-group members and (b) positive intergroup contact can encourage advantaged-group members to take action on behalf of disadvantaged outgroups. Two studies investigated the effects of negative as well as positive intergroup contact. Study 1 ( n = 482) foun...

Although theory suggests that testosterone should facilitate competitive performance, empirical evidence has been mixed. The present study tested the hypothesis that testosterone's effect on competitive performance depends on whether competition is among individuals (individual competition) or among teams (intergroup competition). Sixty participants (50% women) provided saliva samples and were ...

Intergroup biases shape most aspects of person construal, including lower-level visual representations group members' faces. Specifically, ingroup faces tend to be represented more positively than outgroup Here, we used a reverse-correlation paradigm test whether engaging in perspective taking (i.e., actively imagining another person's mental states) can reduce these biased representations. In ...

In two experiments, we analyzed the use of intra-group differentiation between normative and deviant members as an identity mobilization strategy in intergroup negotiations. Because ingroup members sometimes try to obtain the support of outgroup audiences to attain their goals, we propose that in intergroup negotiations, people attempt to minimize the distinction between the parties involved by...
