Evaluated whether children view relationally manipulative behaviors as "aggressive." In study one, relational aggression was the most frequently cited angry behavior for girls' interactions; physical aggression was most frequently cited for boys. In study two, relational aggression and verbal insults were the most frequently cited harmful…

Relations among hormone levels, emotional dispositions, and aggressive attributes were examined in 56 boys and 52 girls, aged 9 to 14 years. (PCB)

Relations between hormone levels and aggressive behavior of adolescents in family interactions were examined. Higher estradiol and androstenedione levels were associated with higher degrees of aggressive behaviors in girls. Findings for boys were sparse. (PCB)

Three studies examined the hypothesis that aggressive-rejected children are unaware of their social status because they are self-protective when processing negative peer feedback. Found that aggressive rejected boys could accurately assess others' social status, but aggressive rejected boys and girls were more unrealistic in assessing their own…

A six-year study investigated relationships between individual development and: (1) changes in aggressive expression; (2) continuities of aggressive behavior in girls and boys; and (3) convergence between self-concepts and social attributions of others in ontogeny. Participants were 220 fourth grade students who were followed from childhood…

Two steps in the social information process model were assessed for socially accepted and rejected children by verbal responses to stories embedded in computer games. Attributions of intent and aggressive problem solutions were correlated with contextual factors (interpersonal context, outcome of game, and story type) and with sex and social…

Among a group of mostly African-American and Hispanic 10- to 14-year-olds, boys believed that parents would disapprove more of retaliation against siblings than friends, whereas girls believed that parents would equally disapprove of retaliation against either target.

Assessed fourth-graders' peer clique characteristics as a function of socioeconomic status, gender, and aggressiveness. Found that rejected youth were less central group members than average-status peers; aggressive preadolescents were no less involved than nonaggressive peers; rejected preadolescents belonged to smaller cliques and cliques…

Findings from 1,027 subjects followed longitudinally from age 10 through age 26 revealed strong connection between aggressiveness ratings at early ages and adult delinquency for boys. Aggressiveness was not predictive of later crime for girls until they reached age 13. For both genders, relation between aggressiveness and crime was largely…

Examined how the social context of working within same- or different-sex peer dyads related to gender-typed ideas expressed in creative stories. Sixth graders collaborated to write creative stories. Boy dyads' stories included more overtly aggressive ideas and fewer prosocial story ideas than girl dyads' stories. Mixed-gender dyads' stories…
