A decades-long trend toward greater racial and ethnic diversity in the United States is expected to continue, with White Americans projected to constitute less than 50% of the national population by mid century. The present review integrates recent empirical research on the effects of making this population change salient with research on how actual diversity affects Whites Americans’ intergrou...

Drawing from the intergroup contact model and self-categorization theory, the authors advanced the novel hypothesis of a valence-salience effect, whereby negative contact causes higher category salience than positive contact. As predicted, in a laboratory experiment of interethnic contact, White Australians (N = 49) made more frequent and earlier reference to ethnicity when describing their eth...

In many Western countries, the proportion of the population that is White will drop below 50% within the next century. Two experiments examined how anticipation of these future ethnic demographics affects current intergroup processes. In Study 1, White Americans who viewed actual demographic projections for a time when Whites are no longer a numerical majority felt more angry toward and fearful...

Interpersonal rejection and intergroup exclusion in childhood reflect different, but complementary, aspects of child development. Interpersonal rejection focuses on individual differences in personality traits, such as wariness and being fearful, to explain bully-victim relationships. In contrast, intergroup exclusion focuses on how in-group and out-group attitudes contribute to social exclusio...

Abstract Past research has found intergroup contact to be a promising intervention reduce prejudice and identified adolescence as the developmental period during which is most effective. Few studies, however, have tested whether contact-based interventions can scaled up improve relations at large scale. The present evaluated when National Citizen Service, large-scale reaching one in six 15- 17-...
