Previous work has shown the robust nature of gender bias in both children and adults. However, much less attention has been paid toward understanding what factors shape these biases. The current preregistered study used parent surveys and child interviews to test whether parents' conversations with their children about and modeling of gender…

Past research has shown that intergroup contact can be a promising intervention to improve intergroup relations and that contact-based interventions might be most effective during adolescence. In postconflict Northern Ireland, widespread residential segregation and a largely separate school system limit opportunities for intergroup contact between…

Children's intergroup attitudes arguably reflect different construals of in- and out-groups, whereby the former are viewed as composed of unique individuals and the latter of homogeneous members. In three studies, we investigated the scope of information (individual vs. category) Jewish-Israeli 5- and 8-year-olds prefer to receive about…

Human beings naturally prefer and support ingroup members more than outgroup members, but to what extent do we "morally value" equal treatment to ingroups and outgroups? Across four preregistered studies, we examined the development of "group-transcendent fairness," that is, the moral endorsement of allocating resources equally…

This study examined prosocial bystander behavior in an online ball-throwing game (Cyberball), toward the exclusion of immigrants and nonimmigrant peers within intergroup and intragroup contexts. Participants were British children (8- to 10-year-olds) and adolescents (13- to 15-year-olds, N = 292; female N = 144). They were an ethnically diverse…

Understanding when children develop a sense of group boundaries has implications for conflict and its resolution. Integrating social identity development theory and the developmental peace-building model, we investigated whether preferences for ethno-religious ingroup symbols mediate the link from child age to outgroup prosocial giving among 5- to…

This longitudinal, quasi-experimental field study investigated affective forecasting as a moderator of positive intergroup contact effects among adolescents. We also examined a novel mediating mechanism that underlies this effect, namely accuracy of perceived outgroup willingness for intergroup contact. Three annual waves of survey data were used…

This study examined preschoolers' social inclusion--the active involvement of new partners into social interactions--in different intergroup contexts. Using an interactive paradigm, 3- to 5-year-old German children played a ball-tossing game with 2 puppets in which 1 puppet initiated the game with the child and another approached the game. In…

Children tell prosocial lies from the age of three years onward, but little is known about for whom they are inclined to lie. This preregistered study examined children's (N = 138, 9-12 years) prosocial lying behavior toward minimal in-group and out-group peers. Additionally, children evaluated vignettes in which an in-group peer told a prosocial…

Given its importance for the emergence of intergroup conflict, the development of other-regarding preferences toward in-group and out-group members has received increasing attention from various disciplines. The present study investigates children's other-regarding preferences toward in-group and out-group members when allocating resources with…

This study investigated children's and adolescents' predictions of inclusion and evaluations of exclusion in interracial and same-race peer contexts. The sample (N = 246) consisted of African American (n = 115) and European American (n = 131) children and adolescents who judged the likelihood of including a new peer, evaluated the group's decision…

Although research has shown the effects of empathy manipulations on prejudice, little is known about the long-term relation between empathy and prejudice development, the direction of effects, and the relative effects of cognitive and affective aspects of empathy. Moreover, research has not examined within-person processes; hence, its practical…

To investigate children's inclusion of language-outgroup members, English-speaking children (8-9 years and 10-11 years of age, N = 57) made inclusion decisions while playing a simulated ball-tossing game, Cyberball, and while evaluating hypothetical scenarios involving language-outgroup members who wanted to play with their group. In the Cyberball…

Prejudice and discrimination as justifications for social exclusion are often viewed as violations of the moral principles of welfare, justice, and equality, but intergroup exclusion can also often be viewed as a necessary and legitimate means to maintain group identity and cohesion (Rutland, Killen, & Abrams, 2010). The current study was…

The goal of this article was to investigate an indirect form of intergroup differentiation in children in the context of racial attitudes: the preference for ingroup members who interact positively with other ingroup members rather than with outgroup members. Study 1 confirmed this general hypothesis with preschool and 1st-grade children,…
