Theory of mind in preadolescence: Relations between social understanding and social competence

Theory of mind (ToM) underlies the ability to attribute mental states to people as a way of understanding their social behaviour. Although ToM development is an active area of research, most empirical investigations focus on infants and young children. Accordingly, the purpose of this study is to assess ToM in preadolescents and to determine whether individual differences in this mentalizing ability, relate to social competence and relate differently for girls and for bolts. It was hypothesised that preadolescents' ability to understand thoughts and emotions in others would be associated with their social competence. 128 preadolescents (64 girls; 64 boys, mean age 11-9) completed peer social competence ratings, a vocabulary task, and participated in a social under standing (ToM) interview. Teacher ratings of the participants' social competence were also collected. Based on composite ToM scores, results indicated positive associations between ToM and (a) peer ratings of social-interaction skills, (b) general vocabulary ability. Separate gender analyses revealed significant effects. Results are discussed in relation to (1) individual differences in social understanding and social competence and (2) effects of socio-cultural context.
