Both sympathetic nervous system (SNS) activity (skin conductance) and parasympathetic nervous system (PNS) activity (respiratory sinus arrhythmia or RSA), as well as their interaction, were included as physiological measures. Participants were 35 5th‐grade children who were placed in two virtual‐peer scenarios; one scenario provided the opportunity to aggress in response to peer provocation (i.e., reactive aggression) and the other scenario provided the opportunity to aggress for instrumental gain (i.e., proactive aggression). Both skin conductance and RSA were assessed at the time that children were given the opportunity to aggress; this simultaneous assessment of psychophysiology and aggression allowed for an exami...

Attachment quality was assessed using the Strange Situation. Although attachment insecurity did not predict SIP, attachment disorganization positively predicted the early SIP steps of hostile attributional bias and aggressive goals. Children with disorganized attachments interpreted ambiguous provocations more negatively (as indicating more hostility, rejection, and disrespect and as resulting in more anger) and endorsed significantly more revenge and dominance goals than children with organized attachments. In contrast, parental sensitivity negatively predicted the later SIP step of positive expectations for aggressive responses. Results further our understanding of the adverse outcomes associated with attachment disorganization.

Research providing connections between the constructs of emotional functioning and social competence is examined. Although there is evidence that accuracy in reading the emotions of others is related to children's social status, there is no research on the relationship between social competence and the ability to monitor one's own emotions. There is some support that high social status is related to the ability to regulate strong feelings effectively, and only few data exist on the relation of emotional display rules and sympathetic responding to social competence.

We extended previous research by using a person-based analytical approach on data from a questionnaire assessing children’s motives independently from the severity of their aggression. Two competing hypotheses were tested. The both subtypes hypothesis holds that both reactive and proactive subtypes exist, as well as a mixed subtype. The reactive only hypothesis holds that only reactive and mixed subtypes exist. Hypotheses were tested on existing data from a community sample of children displaying aggression (Study 1: n = 228, ages 10–13, 54% boys), and two clinical samples of children with aggressive behavior problems (Study 2: n = 115, ages 8–13, 100% boys; Study 3: n = 123, ages 6–8, 78% boys). Teachers reported on children’s reactive and proactive motives. We selected measures available from peers, parents, teachers, and children themselve...

The sample included 144 racially ethnically diverse adolescents (46% male, 53% female, 1% other; M age = 16.02 years). We assessed susceptibility to peer influence behaviorally using the Public Goods Game (PGG) while measuring adolescents’ mean heart rate (MHR) and pre-ejection period (PEP). Three key findings emerged from bivariate dual latent change score modeling: (1) adolescents whose MHR increased more as they transitioned from playing the PGG alone (pre-influence) to playing while simply observed by peers (indirect influence) displayed more prosocial behavior; (2) adolescents whose PEP activity increased more (greater PEP activity = shorter PEP latency) as they transitioned from indirect influence to being encouraged by peers to engage in an...

The second goal was to control for the effects of differential peer treatment and bias on children's behavior by observing children in a standardized procedure with unfamiliar peer confederates.

Eleven play groups, each of which consisted of six familiar African-American 8-year-old boys, met for 45-min sessions on five consecutive days. Social-cognitive interviews were conducted following the second and fourth sessions. Play group interactions were videotaped and examined by trained observers. High rates of proactive aggression were associated with positive outcome expectancies for aggression/assertion, frequent displays of assertive social behavior, and low rates of submissive behavior. Reactive aggression was associated with hostile attributional tendencies and frequent victimization by peers. Victimization was associated with submissive behavior, hostile attributional bias, reactive aggression, and negative outcome expectations for aggression/assertion. These results demonstrate that there is a ...

Past research has distinguished between three types of accuracy: generalized accuracy, a perceiver's accuracy about how a target interacts with others in general; perceiver accuracy, a perceiver's view of others corresponding with how the perceiver is treated by others in general; and dyadic accuracy, a perceiver's accuracy about a target when interacting with that target. Researchers have proposed that there should be more dyadic than other forms of accuracy among well-acquainted individuals because of the pragmatic utility of forecasting the behavior of interaction partners. We examined behavioral aggression among well-acquainted peers. A total of 116 9-year-old boys rated how aggressive their classmates were toward other classmates. Subsequently, 11 groups of 6 boys each interacted in play groups, during which observations of aggression were made. Analyses indicated strong generalized accuracy y...

Participants were 57 second-grade children (22 girls and 35 boys). Data on reactive aggression, proactive aggression, depressive symptoms, and peer rejection were collected from four sources (parents, teachers, peers, and self). Results revealed that reactive aggression, but not proactive aggression, was positively related to depressive symptoms. Furthermore, peer rejection partially mediated the relation between reactive aggression and depressive symptoms.
