The purpose of the study was to evaluate neuropsychological and behavioral rating measures of executive functions (EF) in
children with two subtypes of ADHD, Asperger syndrome (AS), and controls. Relative to the control group, the clinical groups
experienced more difficulty in EF. The AS group showed the most difficulty in emotional control, behavioral regulation, fluid
reasoning, and planning compared to the ADHD groups. Number of symptoms of ADHD or AS was found to be significantly related
to ratings of difficulty with behavior regulation, metacognition, and general behavioral regulation across the sample. These
findings indicate that children with AS or ADHD may have a differing EF profile and thus, may respond differentially to interventions.
