Perceived threat from outgroups is a consistent social-environmental antecedent of intergroup bias (i.e. prejudice, ingroup favoritism). The serotonin transporter gene polymorphism (5-HTTLPR) has been associated with individual variations in sensitivity to context, particularly stressful and threatening situations. Here, we examined how 5-HTTLPR and environmental factors signaling potential out...

The outcomes of social interactions among members of different groups (e.g., racial groups, political groups, sexual orientation groups) have long been of interest to psychologists. Two related literatures on the topic have emerged-the intergroup interaction literature and the intergroup contact literature-in which divergent conclusions have been reported. Intergroup interaction is typically fo...

INTRODUCTION Internet gaming disorder (IGD) is usually defined as the inability of an individual to control internet gaming resulting in serious negative consequences, and trait impulsivity has been viewed as a hallmark feature of IGD. Recent studies have suggested that the structural integrity of the white matter (WM) plays an important role in the neuromediation of an individual's impulsivity...

Social and policy interventions over the last half-century have achieved laudable reductions in blatant discrimination. Yet members of devalued social groups continue to face subtle discrimination. In this article, we argue that decades of anti-discrimination interventions have failed to eliminate intergroup bias because such bias is contagious. We present a model of bias contagion in which int...

Intergroup contact and evaluations about race-based exclusion were assessed for majority and minority students in fourth, seventh, and tenth grades (N = 685). Students were presented with scenarios depicting cross-race relations in contexts of dyadic friendship, parental discomfort, and peer group disapproval. Participants reporting higher levels of intergroup contact gave higher ratings of wro...

Research on intergroup ideologies (colorblindness, multiculturalism) has increased our understanding of intergroup attitudes. This article reports empirical tests of the relation between a newly studied ideology, polyculturalism (ideology focusing on interactions and connections among racial/ethnic groups), and intergroup attitudes. Across four studies (with racially/ethnically diverse U.S. und...
