Abstract

Objectives：The study was performed to compare the executive function(EF；Inhibition, Planning and Working memory) between ADHD and normal group, and to controll the effect of age and intelligence. And the function of inhibition was assessed in two dimensions(cognitive inhibition and motor inhibition).
Methods：K-WISC III and EF test(Go-No-Go, Stroop test, Tower of Hanoi, Digit) was administered to both 25 children with ADHD and 25 normal control participants, all aged between 7 and 12. The results were analyzed after statistically controlled for age and intelligence.
Results：Children in the ADHD group had significantly lower IQ score than those in the control group and consistent relations were found between the child’s age and the study’s major variables. Once IQ and age were controlled, results indicated that children with ADHD had deficit only cognitive inhibition and motor inhibition. There was no significant difference in planning and working memory.
Conclusion：These results suggested that specific deficits in inhibition control rather than general EF deficits are associated with ADHD. So inhibition is the core problem of children with ADHD. Thus, the therapeutic approach focused on cognitive inhibition and motor inhibition is required.
