A new semi-nonverbal task glance, moderate role of cognitive flexibility in ADHD children's theory of mind.

Studies have documented both executive functions (EF) impairment in children with Attention Deficit / Hyperactivity Disorders (ADHD) and Theory of Mind (ToM), yielding mixed results, possibly because of a variety of tasks used, all requiring different levels of language skills. To investigate the relationship between ToM and EF with non-language-based tasks. Thirty ADHD (7-9 years old) were compared to thirty controls (age and IQ matched). Participants' ToM was assessed using the Animated Triangles task and two EF tasks, namely spatial control test, the Stockings Of Cambridge (SOC) and rule and acquisition test, the Intra-Extra Dimensional set shift (IED)-from the neuropsychological battery of the Cambridge Neuropsychological Test Automated Battery (CANTAB). ADHD group had a significant ToM and EF impairment relative to the control group. ToM was not significantly correlated with EF; however, the performance on IED tasks affected the performance on ToM tasks. The study provides evidence for a link between the abilities to attribute correct mental states to others, planning and shifting attention in ADHD children, suggesting the ability to rely on cognitive flexibility in the face of a changing environment plays a role in explaining the association between ToM and EF.
