Drawing on social identity theory, this study explored the impact of the peer group on childhood bullying. Participants were 351 students, aged 8 to 13 years. Involvement in bullying, friendship group membership, norms of particular groups, and intra-group positions (prototypical vs. peripheral) were determined using peer reports. Results revealed…

This research investigated the role of children's implicit theories of peer relationships in their psychological, emotional, and behavioral adjustment. Participants included 206 children (110 girls; 96 boys; M age = 10.13 years, SD = 1.16) who reported on their implicit theories of peer relationships, social goal orientation, need for approval,…

This study of economically disadvantaged 13-year-olds examined the relations between serious reading difficulties and clinical levels of externalizing behaviors in school. The variable-centered results showed that family variables, adolescent verbal ability, and negative emotion patterns differed in uniquely predicting reading achievement and…

Core findings of the ongoing National Institute of Child Health and Human Development study of early child care and youth development through the end of the primary-school years are summarized, highlighting the fact that both positive effects of good quality care on cognitive-linguistic-academic functioning and negative effects of extensive…

This study examined the relations of parent-youth agreement and disagreement during a joint problem-solving task and multi-methodological indices of socioemotional outcomes in adolescents (mean age = 13). One hundred and sixty-seven parents and their adolescent children participated. Each parent-youth pair played the interactive game "Jenga", and…

This study investigated the role of mutual dislike dyads (MDDs) in the development of aggressive behavior across the middle childhood years. Of particular interest was whether involvement in MDDs predicted later aggression, and whether the magnitude of the association between MDDs and later aggression varied based on characteristics of target…

The idea that classroom social ecologies are shaped by the aggregate effects of peers' prior care experiences is provocative, even though the evidence is weak that this explains the small and diminishing effect of childcare experience in the National Institute of Child Health and Human Development study. Small effects may indeed be small effects,…

This study examined the heterotypic continuity of aggression hypothesis (physical to indirect) using independent teacher reports of aggression drawn from a nationally representative sample of 749 Canadian girls and boys. Confirmatory factor analysis using an accelerated longitudinal design confirmed a two-factor model of physical and indirect…

Relations among parental depressive symptoms, overt and covert marital conflict, and child internalizing and externalizing symptoms were examined in a community sample of 235 couples and their children. Families were assessed once yearly for three years, starting when children were in kindergarten. Parents completed measures of depressive symptoms…

In an intriguing account, the hypothesis is proposed that elevating effects of quantity of childcare on aggression might not, as other research has suggested, be dissipating over time, but instead be diffusing across groups of children. Paradoxically, this diffusion may also affect children with little or no experience with non-maternal care. If…

The main research question of this study is whether children's emotional responses to specific stress-evoking situations (anger or anxiety) and the coping strategies they would use are related. Furthermore, it is asked if these relationships are consistent over a specific age range. A total sample of 432 second graders participated in a…

This prospective, longitudinal study examines individual differences in two conceptually related but empirically distinct domains of social-cognitive competence (cognitive interpretive understanding and interpersonal perspective co-ordination) as moderators of the relation between peer rejection and neglect and behavioral and emotional problems in…

This study investigated the entry behavior and temperamental characteristics of aggressive/rejected and nonaggressive/popular kindergarten and first-grade children. An analog entry situation was used to assess children's entry skills. Aggressive/rejected children had more difficulty than nonaggressive/popular children delivering their entry bids…
