Research on sex differences in antisocial behaviour may shed light on the causes of childhood antisocial behaviour. Using a longitudinal design, we tested whether there were sex differences in the amount of harsh discipline children received or in the effect of harsh discipline and whether this accounted for sex differences in later conduct…

This study tested assumptions and conclusions reached in an earlier confirmatory factor analysis (CFA) study of the social competence (SC) construct for preschool children. Two samples (total N = 408; a new Portuguese sample and one from US samples that had participated in the original study) contributed data. Seven SC indicators were tested for…

The present study examined the relationships between caregivers' self-reported positive and negative emotional expressiveness, observer assessments of children's emotion regulation, and teachers' reports of children's internalizing and externalizing behaviors in a sample of 97 primarily African American and Hispanic Head Start families. Results…

Parent-reported reactions to children's negative emotions and child negative emotionality were investigated as correlates of internalizing and externalizing behaviors. Children (N = 107) and their parents participated in a short-term longitudinal study of social development. Mothers and fathers independently completed questionnaires assessing…

The present study examined the association between theory of mind and indirect versus physical aggression, as well as the potential moderating role of prosocial behavior in this context. Participants were 399 twins and singletons drawn from two longitudinal studies in Canada. At five years of age, children completed a theory of mind task and a…

Concurrent and longitudinal relations among parental emotional expressivity, children's sympathy and children's prosocial behavior were assessed with correlations and structural equation modeling when the children were 55-97 months old (N = 214; M age = 73 months, SD = 9.59) and eight years later (N = 130; ages 150-195 months old, M = 171 months,…

Mothers' emotion talk, children's emotion talk, and children's understanding of emotion were examined in 50 mother-child dyads at 41 months. Language measures included total emotion words, unique emotion words, labels, explanations, and different types of explanations. Children's emotion understanding was assessed for labeling, situation, and…

We analyzed the relations between teacher reports of aggressive behaviors, caregiver reports of their use of physical discipline, anger perception accuracy, and anger perception bias in middle childhood and teacher reports of aggressive behaviors two years later in a sample of children from economically disadvantaged families (n = 152). Fisher…

Experimental research suggests the differentiation of "nice" and "nasty" theory of mind (ToM). Over 5000 parents from the Twins Early Development Study reported on nice (e.g., being considerate) and nasty (e.g., blaming others) behaviours following their twins' second, third, and fourth birthdays. Factor analyses yielded four factors and it was…

In this study we described development of boys' and girls' games on the school playground at recess as they progressed across the first year of primary school in London (UK) and Minneapolis (USA) in order to document age-related trends in games during this period and to examine the predictive role of games in children's adjustment to school and…
