Abstract
Research Findings. The present study examined relations between social-cognitive skills, aggression, and social competence using teacher questionnaires and tabletop tasks with preschool and kindergarten children. It was hypothesized that the acquisition of a theory of "mind," as indexed by an understanding of false beliefs, might be related to social behavior for this age group. Overall, results indicated that both generation of forceful solutions in a traditional social-problem solving task and performance on the false belief tasks were significantly related to social competence, after controlling for the effects of age, language comprehension, and teacher ratings of aggression. In addition, theory of mind understanding was a better predictor of social competence than performance on a more traditional social information-processing task that involved the generation of alternative solutions to interpersonal problems. Practice. The implications of these findings for preschool and kindergarten peer relations and their potential relevance to treatment of deficits in social skills are discussed. Specifically, training in an understanding of counterfactual thinking (e.g., through increased and structured opportunities to engage in pretend play and storytelling) may enhance preschooler social skills.
