Parent-child attachment is robustly associated with typical patterns of emotion regulation but rarely examined in relation to changes in emotion in response to events. We studied how attachment is related to emotion reactivity to positive and negative events and to immediate and delayed emotion recovery from social exclusion. The sample (78%…

This study investigated how two aspects of the classroom environment (teachers' emphasis on mastery goals and descriptive norms (i.e., the average student disruptive, prosocial, and achievement-related behavior in a classroom), moderated the relationship between student behaviors and coolness. The sample included 976 students nested in 54 fifth-…

Friendship is a developmentally significant relationship in childhood and adolescence that contributes to socioemotional, social-cognitive, and psychological development and well-being. It is a dyadic relationship based on mutual affection, with both friends thinking of each other as friends. Despite this definitional understanding of the dyadic…

Popularity and likability--two measures of adolescent peer status--have been examined frequently within Western cultures but relatively rarely within Eastern cultures. This study offered a cross-cultural comparison of adolescent peer status to examine whether these constructs and their correlates vary between the United States and China. The study…

In this study, the effects of peer acceptance and rejection on global self-esteem and emotional school engagement in adolescents were investigated. Moreover, in line with the differential susceptibility hypothesis, we examined the potential moderating effect of a polymorphism in the serotonin receptor gene (i.e., 5-HTTLPR). The sample consisted of…

Peer victimization is associated with increased risk for mental health problems. These adverse psychological outcomes are linked with altered cognitive and emotional processes and their related neural functioning. In the present study, by using functional magnetic resonance imaging (fMRI), we examined whether peer victimization was associated with…

In this two-wave longitudinal study, concurrent and longitudinal relations among teacher-reported shyness, peer acceptance, and academic achievement were examined (Ns = 162 and 155; and Ms[subscript age] = 6.09 and 7.07 years). Concurrently, at both times, shyness was negatively related to peer acceptance and academic achievement, and peer…

This study investigated friend influence over mathematics achievement in 202 same-sex friendship dyads (106 girl dyads). Participants were in the third grade (around age 9) at the outset. Each friend completed a questionnaire describing interest in mathematics and a standardized mathematical reasoning assessment. Peer nominations provided a…

A growing body of literature indicates that childhood emotion regulation predicts later success with peers, yet little is known about the processes through which this association occurs. The current study examined mechanisms through which emotion regulation was associated with later peer acceptance and peer rejection, controlling for earlier…

This study examined the association between ethnicity-related context variables and the prosocial behavior of early adolescents in ethnically/racially diverse schools. Specifically, youths' perceptions of greater representation of same-ethnic peers at school, school support for ethnic diversity, and engagement in and valuing cross-ethnic contact…

Attachment theorists suggest that attachment security with parents supports the quality of social adaptation in peer groups during early childhood, and numerous studies supporting this conjecture have been published. Most of these studies used enacted representations rather than mental representations of attachment security, and most studies…

Gene-environment studies on adolescents' peer contexts are important for understanding the interplay between biological and social antecedents of adolescent psychopathology. To this end, this study examined the roles of serotonin transporter (5-HTTLPR) and preadolescent and early adolescent peer rejection and acceptance, as well as the interaction…

In this study on being ignored by peers, 934 twelfth-grade students reported on their experiences of being ignored, victimized, and socially withdrawn, and completed measures of friendship and psychological adjustment (depression, self-esteem, and global satisfaction). Peer nominations of being ignored, victimized, and accepted by peers were also…

This study examined how "homophily" (similarity) and "propinquity" (availability) simultaneously predict both unidirectional and reciprocal cross-ethnic friendships among early adolescents in ethnically diverse classrooms. In a sample of sixth-grade students, liking nominations were used as the indicator of friendship, and both…

Using peer nominations of physical aggression and perceived popularity in the spring semester of fifth grade, we identified 54 popular aggressive and 42 nonpopular aggressive preadolescents in a diverse sample of 318 participants recruited from an urban school district. Physical aggression in the spring semester of sixth grade was included to…
