| Abstract:
The underlying components of executive functioning in 18 non-treated and 18 treated children (with medication) with ADHD were compared with 18 normal children. There were 3 girls and 15 boys in each group and their age ranged from 7 to 12 years old. All the children responded to the Stroop Color-Word Test (Stroop, 1935), Wisconsin Card Sorting (Grant & Berg, 1948), and Continuous Performance Tests (Rosovold, Mirsky, Sarason, Bronsome & Beck, 1956), and the Digit Span subscale (Wechsler, 1974). The results of MANOVA showed that compared to treated and normal sample, the non-treated sample performed significantly weaker in most of executive functions. No significant differences were found between the performance of treated and normal children in executive functions.
