The complex temporal associations among moral disengagement, moral emotions, and aggressive behavior were investigated within a short-term four-wave longitudinal study in a sample of early adolescents (at T1: N = 245; M[subscript age] = 12.16 years; SD = 0.85). Moral disengagement and aggressive behavior were investigated by validated self-report…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure…

This article describes Prevent-Teach-Reinforce for Young Children (PTR-YC), a model based on extensive research that is designed for feasibility and effectiveness for treating challenging behaviors in classroom settings. This model is designed to meet the needs of children with and without disabilities who engage in challenging behavior that…

This study examines the role of moral disengagement in fostering engagement in aggression and violence through adolescence to young adulthood in accordance with a design in which the study of individual differences and of their relations is instrumental to address underlying intraindividual structures and process conducive to detrimental conduct.…

Callous-unemotional (CU) traits have proven important for designating children and adolescents showing a pattern of particularly severe, stable, and aggressive antisocial behaviors (Frick, Ray, Thornton, & Kahn, 2014). Individuals with secondary CU traits represent a subpopulation that are distinguished from those with primary CU traits by…

The purpose of this article is to use a facet theory research approach to provide a clear, coherent, and integrated model of international students' experiences based upon the findings of psychological research into students when studying abroad. In research that employs a facet theory approach events are classified in terms of their constituent…

In the present study, longitudinal data from the "NICHD Study of Early Child Care and Youth Development" were used to test a theoretical model in which one aspect of children's self-regulation skills--their inhibitory-control abilities--were hypothesized to show reciprocal relations with their levels of teach of teacher-child across the…

This study aimed to support the theory of popularity contagion, which posits that popularity spreads among friends spontaneously and regardless of behavioral changes. Peer nominations of status and behavior were collected annually between 6th and 12th grades from a total of 1062 adolescents. Longitudinal hypotheses were mostly supported using path…

Exposure to stress is associated with a wide range of internalizing and externalizing problems in adolescents, including aggressive behavior. Extant research examining mechanisms underlying the associations between stress and youth aggression has consistently identified social information processing pathways that are disrupted by exposure to…

Psychologists have long debated the role of early experience in social and cognitive development. However, traditional approaches to studying this issue are not well positioned to address this debate. The authors present simulations that indicate that the associations between early experiences and later outcomes should approach different…

Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

Suicide is a global concern, hence, cross-cultural research ought to be important; yet, there is a paucity of cross-cultural study in suicidology. This study sought to investigate suicide notes drawn from India and the United States, as these countries have similar suicide rates but markedly different cultures. A thematic or theoretical-conceptual…

Existing research suggests that there is a relation between academic/cognitive deficits and externalizing behavior in young children, but the direction of this relation is unclear. The present study tested competing models of the relation between academic/cognitive functioning and behavior problems during early childhood. Participants were 221…

Studies show that children who use relational aggression process social information in unique ways; however, findings have been inconsistent and limited by methodological weaknesses. This short-term longitudinal study examined developmental changes in 245 (49% female; ages 8-13) 3rd through 8th graders' normative beliefs about relational…
