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…

The problem of youth violence has become a national priority given both the cost and repercussions to youth, to the school systems, and to society. Over the past two decades there has been increasing research examining gender differences in the expression of aggression. This research has suggested that boys typically display their aggression…

Research suggests that involvement in relational aggression is associated with serious adjustment problems, including concurrent and future social maladjustment (e.g., problematic friendships; rejection), internalizing problems (e.g., depressive symptoms), and school avoidance. Despite the burgeoning literature focusing on the harmful and damaging…

The purpose of these studies was to examine the frequency and stability of relational and physical aggression and their associations with social-psychological adjustment or peer victimization, and how friendships are involved in the relations between forms of aggression and peer victimization in Japanese children. The sample consisted of 452…

This study examined the structural relations of preadolescents' inattention and hyperactivity/impulsivity, aggressive and prosocial behaviors, and peer functioning. There were 739 fourth (n = 239) and fifth (n = 500) graders (52.23% boys) in Taiwan who participated in this study. Preadolescents' inattention and hyperactivity/impulsivity were…

This short-term longitudinal study examined the associations between cross-racial/ethnic friendships and relative changes in forms of peer victimization or peer support and the roles of classroom diversity and sociometric status (i.e., social preference) in these associations. A total of 444 children (age range: 9-10 years) from…

The aim of this study was to examine the antecedents of cross-racial/ethnic friendships and same-racial/ethnic friendships. The sample consisted of 444 (161 African American, 108 European American, 100 Asian American, and 75 Latino) children who were in the fourth grade from 39 classrooms in 10 public elementary schools. Results of Mixed Linear…

Results of a study of aggression and friendship involving 315 children, ages 9-12, indicated that friendships of relatively aggressive children were characterized by relatively high levels of intimacy, exclusivity/jealousy, and relational aggression within the friendship context. In contrast, the friendships of overtly aggressive children were…

The school classroom and playground provide an important context for learning about young children's social interactions. A multimethod, multiinformant, short-term longitudinal study was conducted to investigate the utility of including school-based observational assessments of both form (i.e., physical and relational) and function (i.e.,…

The purpose of this study was to examine the frequency and correlates of cross-racial/ethnic friendships. The sample consisted of 509 (188 African American, 135 European American, 106 Asian American, and 80 Latino) children in 4th grade from 39 classrooms in several public elementary schools. The authors hypothesized that (a) the frequency of…

Although research on assertion has made important advances in our understanding of young children's behavior within their peer group, there has been a significant limitation in that prior studies have generally not given attention to the gender specific social goals of girls. To advance the literature, this short-term longitudinal study uses a…

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…

The role of siblings ("N" = 50) in the display of physical and relational aggression among peers during early childhood was explored. Specifically, sibling pairs' rates of physical and relational aggression were assessed in their independent social contexts. Findings indicated low to moderate levels of intercorrelation between physical and…

To understand the development of relational aggression during early childhood, 91 girls and boys ("M" age=39.0; "SD"=7.6 months) and their teachers participated in an 18-month longitudinal study. Children were observed for relational and physical aggression during free play in four time periods. Individually administered interviews were conducted…

Social information-processing patterns in 9- through 12-year olds at least partially supported 3 hypotheses: only reactive-aggressive children would demonstrate hostile biases in their attributions of intentions in provocation situations; only proactive-aggressive children would evaluate aggression in positive ways; and proactive-aggressive…
