Several studies have investigated factors guiding children's decisions when learning from others, although less is known about factors that govern children's decisions when they transfer knowledge to others. Here we asked whether children would privilege ingroup members when teaching and, if so, whether this tendency would persist when…

The primary purpose of the present study was to examine the contributions of social, academic, and psychological characteristics of peer groups to individual development in the same and different domains in Chinese children. Participants included 1,864 elementary school students (945 boys, M[subscript age] = 11 years) in China. One-year…

Social adjustment is critical to educational and occupational attainment. Yet little research has considered how the school's socioeconomic context is associated with social adjustment. In a longitudinal sample of Australian 4- to 8-year-olds (N = 9369; 51% boys) we tested the association between school average socioeconomic status and social…

The association between children's social-status within their peer-group and their prosociality was examined among fourth and sixth graders (N = 276), using sociometric nominations, and actual sharing with a fellow in-group member, or a member of an out-group. Results show an overall increase in sharing with age, and an overall correlation between…

Reputational concerns are known to promote cooperation. Individuals regularly act more prosocially when their behavior is observable by others. Here, we investigate 4- and 5-year-old (N = 144) children's reputational strategies in a competitive group setting. The aim of the current study was to explore whether children's sharing behavior is…

This study adopts a cultural ecological perspective to examine how cumulative effects of external transcultural and cultural strengths are related to baseline and changes in three markers of Mexican-origin adolescents' self-growth (i.e., resilience, life meaning, and discipline). Using a three-wave longitudinal data set (5 years) of 604…

We examined the development of children's positive and negative attitudes toward other-gender peers over 1 year, and explored the longitudinal social consequences of holding positive or negative attitudes on the beholder of these attitudes. Participants were 206 second graders (Mage = 7.18 yrs, SD = .56, 50% girls) and 206 fourth graders…

Children hold strong ingroup biases from a young age, liking ingroup over outgroup members and preferring them as social learning models. Simultaneously, children are also highly prosocial--both in their own helping behaviors and their avoidance of those who behave antisocially. This study explores how children of 2 age groups (4-5 and 7-8 years)…

This study examined 131 U.S. middle class early, middle, and late adolescents' (M[subscript age] = 12.74, 15.81, and 20.40 years, respectively) narratives regarding experiences of disclosure, concealment, and lying to parents and responses to direct probes about lessons learned about self and parents. The thematic content focused primarily on…

This study investigated children's evaluations of peer group members who deviated from group norms about equal and unequal allocation of resources. Children, ages 3.5 to 4 years and 5 to 6 years (N = 73), were asked to evaluate a peer group member who deviated from 1 of 2 group allocation norms: (a) equal allocation of resources, or (b) unequal…

The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals)…

This study tests the hypothesis that adolescents with romantic partners are less similar to their friends on rates of alcohol abuse than adolescents without romantic partners. Participants (662 girls, 574 boys) ranging in age from 12 to 19 years nominated friends and romantic partners, and completed a measure of alcohol abuse. In hierarchical…

The present study evaluated whether 3 indices of friendship adjustment (mutual friendship involvement, friendship stability, friendship quality) are important, but overlooked, moderators of the impact of anxious-withdrawal on trajectories of psychological maladjustment during early adolescence. Participants included 271 young adolescents (51%…

To investigate the developmental course of aggression and peer victimization in childhood and adolescence, distinct subgroups of children were identified based on similarities and differences in their physical, verbal and relational aggression, and victimization. Developmental continuity and change were assessed by examining transitions within and…

Social development theories highlight the centrality of peer groups during adolescence and their role in socializing attitudes and behaviors. In this longitudinal study, we tested the effects of group-level prejudice on ensuing positive and negative interpersonal interactions among peers over a 7-month period. We used social network analysis to…
