Extending John Bowlby's hypothesis that dysfunctional anger is a predictable outcome of insecure attachments to parents, this study investigated the relationship between current parent-adolescent attachment and both the experience and expression of anger. Participants included 776 students (379 boys and 397 girls) in grades 8-12. As predicted…

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…

Enriched environments may moderate the effect of genetic factors on prosocial leadership (gene-environment interaction, G × E). However, positive environmental experiences may also themselves be influenced by a genetic disposition for prosocial leadership (gene-environment correlation, rGE). Relating these processes to friendships, the present…

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…

Harsh parenting and child characteristics such as opposition and aggression have been found to relate to bullying, victimization, and bullying-victimization, yet not all children display equal vulnerability to harsh parenting. The monoamine oxidase A gene ("MAOA"; "low-activity" variant) may be a key vulnerability allele as it…

We examined behavior problems in 80 adolescents (39 male; mean age = 15.74 years) adopted in early childhood by Canadians from globally depriving Romanian institutions. Overall, rates of clinically significant behavior problems were comparable to rates found in younger postinstitutionalized adopted children. The association between duration of…

This investigation used two-part growth modeling and cross-lagged panel analysis to examine the predictive function of parenting and teacher-child relationship on the likelihood of children showing problems with parent-rated physical aggression, and on the severity of problems, for 374 children followed from prekindergarten and first grade.…

Family socioeconomic status (SES) and the quality of maternal behavior are among the few identified predictors of child executive functioning (EF), and they have often been found to have interactive rather than additive effects on other domains of child functioning. The purpose of this study was to explore their interactive effects in the…

The objectives of this longitudinal study were to predict the tobacco and alcohol use of Indonesian Muslim adolescents from their religiosity and the substance use of friends and network affiliates. At Year 1, there were 996 participants from eighth grade (n = 507, age = 13.4 years) and 10th grade (n = 489, age = 15.4); 875 were followed into the…

This study examined associations between parents' attributions of culpability and their observed interventions into sibling conflict. A total of 61 primary caregivers judged who was at fault for a sibling conflict and subsequently discussed the event with their two children (aged 4-10 years). Nonunilateral fault attributions (blaming both children…

Representations of the "tree of life" such as cladograms show the history of lineages and their relationships. They are increasingly found in formal and informal learning settings. Unfortunately, there is evidence that these representations can be challenging to interpret correctly. This study explored the question of whether children aged 7-11…

Previous research has identified school bonding as protective against substance use during adolescence. However, there is still a question as to whether school involvement predicts changes in substance use or if substance use actually predicts changes in level of school bonding. This study investigated the relationship between school bonding and…

The present study compared 6- to 9-year-old children's reports of their decisions to express anger, sadness, and physical pain; methods of controlling and communicating felt emotion; and reasons for doing so in response to hypothetical situations across three groups: old-city India (n = 60), suburban India (n = 60), and suburban United States (n =…

This study examined via teacher reports the behavioral correlates of different forms of nonsocial play among Chinese preschoolers, as well as potential gender differences in the linkages in a sample of preschoolers (249 boys, 257 girls) from two cities in mainland China. Measurement models estimated with two-group confirmatory factor analyses…

Age-related and individual differences in adolescents' and emerging adults' stories of real-life empathic and nonempathic experiences were examined. A total of 29 adolescents (M = 15.28, SD = 0.99) and 31 emerging adults (M = 18.23, SD = 0.56) told stories of empathic and nonempathic life events and completed measures of authoritative parenting…
