Executive function, emotion regulation, and maternal report of child temperament in children with PDD
Executive function, emotion regulation and temperament were examined in children with PDD and typical controls matched for approximate cognitive ability. The children were required to perform an executive function search task that involved switching set after a response was well established, and a delay of gratification task. Mothers completed the 195-item Children's Behavior Questionnaire (CBQ), which addressed temperament's overarching factors: Effortful Control, Surgency/Extraversion and Negative Emotionality. No differences were found between groups on the executive function or emotion regulation tasks, with the exception that 28% of children with PDD were unable to meet the criterion required to be tested on the executive control task. Children with PDD were rated as lower in Effortful Control, showed a smaller range of expression in Surgency/Extraversion and appeared to use qualitatively different coping strategies in the delay of gratification task than did typical children.
