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 examined the prospective links between maladaptive anger regulation and aggressive behavior in middle childhood over a 10-month period, analyzing the mediating influence of peer problems. Participants were 599 elementary school children in Germany, aged 6-10 years at Time 1 (T1) and 7-11 years at Time 2 (T2). Anger regulation at T1 was…

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…

Peer victimization appears heritable, but it is unclear whether the traits that confer genetic risk require time and familiarity with a perpetrator to manifest or whether novel and brief interactions can lead to received aggression that demonstrates similar genetic risk. We examined 20-minute, peer-play interactions between 5-year-olds, pairing…

Children's ability to manage the expression of sadness is critical to their development and adjustment. Although parents have been the primary focus of research examining sadness socialization, many acknowledge the influence of other agents such as children's peers. The present research evaluated one type of emotion socialization--reactions to…

This study investigated the relationships between three psychopathic dimensions (callousness/unemotionality, grandiosity/manipulation, and impulsivity/irresponsibility) and reactive and instrumental aggression in a community sample of early adolescents (N = 243, age M = 12.29, SD = 1.18). The moderating role of moral disengagement (MD) was also…

This study assesses the relationships between children's shy and antisocial/aggressive behaviors and maternal beliefs, and concomitant parenting behaviors. Structural equation models examined 199 mothers' perceptions of aggression and shyness in their preschool-age children (average age = 59.63 months); maternal beliefs (i.e., locus of control,…

The relations among peer victimization, effortful control, school engagement, and academic achievement were examined in a group of 390 (212 boys and 178 girls) racially diverse (38.20% Latino and 46.70% White) 6- to 10-year-old children. Specifically, a multimethod, multi-informant approach was used in which data were gathered using self-report,…

This study examined the relations among facial attractiveness, peer victimization, and internalizing problems in early adolescence. We hypothesized that experiences of peer victimization would partially mediate the relationship between attractiveness and internalizing problems. Ratings of attractiveness were obtained from standardized photographs…

Research has demonstrated consistent positive associations between perceived parental psychological control and adolescents' depressive symptoms, but the direction of influence remains unclear. Using a cross-lagged longitudinal design in two samples of late (Study 1, N = 396) and middle (Study 2, N = 724) adolescents, this study compared three…

Converging evidence indicates that maltreated foster children have more behavior problems and poorer peer relations than nonmaltreated, biologically reared youths. However, it is unclear whether deficits in peer relations operate independently or as a result of increased behavior problems and whether outcomes for foster children differ by sex. To…
