Theory of mind, executive function and social competence in boys with ADHD

Twenty-two boys with a diagnosis of ADHD were com-KEYWORDS pared with 22 typically developing boys on an advanced theory of mind task and on two tasks measuring aspects of executive function. Parents completed rating forms measuring general social competence, as well as mentalizing and non-mentalizing social behaviours. There were no differences between the groups on the advanced theory of mind measure.The children with ADHD scored more poorly than controls on an inhibition task but not on a planning task once age and IQ had been covaried. Ratings of social competence were correlated with theory of mind and executive function ability for the typically developing controls but not for the children with ADHD. The results are discussed in terms of inhibitory and social information processing accounts of ADHD.
