One-quarter of the Head Start population has a mother who participated in the program as a child. This study uses experimental Head Start Impact Study (HSIS) data on 3- and 4-year-olds (N = 2,849) to describe multigenerational Head Start families and their program experiences. In sharp contrast to full-sample HSIS findings, Head Start has large,…

This study investigated differences in children's and adolescents' experiences of harming their siblings and friends. Participants ("N" = 101; 7-, 11-, and 16-year-olds) provided accounts of events when they hurt a younger sibling and a friend. Harm against friends was described as unusual, unforeseeable, and circumstantial. By contrast,…

This meta-analytic review of 148 studies on child and adolescent direct and indirect aggression examined the magnitude of gender differences, intercorrelations between forms, and associations with maladjustment. Results confirmed prior findings of gender differences (favoring boys) in direct aggression and trivial gender differences in indirect…

Eight stump-tailed macaques were reared individually and either given all of their daily social experience in darkness or given half in the dark and half in the light. Results suggest that vision is especially important in the maintenance of assertive behaviors and in the instigation and direction of aggressive behaviors. (Author/RH)

Tests the relationship between social cognition and children's aggressive behavior. Aggressive and nonaggressive boys from grades 2, 4, and 6 were exposed to a frustrating negative outcome instigated by an unknown peer who acted with either hostile, benign, or ambiguous intent. (CM)

Tests the hypothesis that a child's activity preferences may predict subsequent changes in the child's aggression, insofar as activity preferences partly determine how much time the child spends in aggression-conducive situations. (Author/RH)

Three kinds of prosocial behavior (helping, sharing, and comforting) were studied in experimental and natural settings, in 108 children ages 3 to 7 1/2. (BRT)

Observed 18- to 30-month-olds' use of force against peers. Found no sex differences in average aggression levels or in mothers' aggression ratings. Rate of hitting peers and mothers' ratings were stable over 6 months for girls only. Toddlers especially sensitive to peers' possible intentions hit peers more and were more likely than to use force…

Examined whether children who vary in their behavioral responses to ambiguous provocation but have similar attributional processes differ in their social goals and self- efficacy perceptions. Subjects were 781 4th and 5th graders. Found that aggressive, withdrawn, and problem-solving responders differed in the social goals and self-efficacy…

Tested four different theoretical models (risk, protective, potentiator, and person-environment fit) describing ways that geographical neighborhoods might be associated with aggression and peer relationship problems in 1,271 elementary school children. Results suggest a protective effect of middle-SES neighborhoods on the aggressive behavior among…
