Predicting aggressive behavior in the third year from infant reactivity and regulation as moderated by maternal behavior

Abstract

AbstractThe degree to which infant attention behaviors, together with infant reactivity to frustrating events, predict aggressive behavior at 2.5 years, and the moderating effect of maternal behavior were tested with 64 low-risk mothers and infants. Mothers rated infant negative reactivity at 5 months and aggressive behavior and maternal trait anger at 2.5 years; infant and maternal behaviors were observed at 6 months. Based on hierarchical multiple regressions, infantattention tofrustrating events at 6 months positively predicted aggressive behavior, whereaslooking away fromfrustrating events was associated with less aggressive behavior for girls only. High reactivity to limits predicted aggressive behavior only when mothers encouraged infant attentiontothe frustrating event, suggesting that maternal behavior amplifies developmental pathways associated with infant temperament.
