Abstract

Objective:We aimed to prove that disinhibition in children with ADHD affects other cognitive function and learning achievement by comparing the intelligence, memory and frontal-executive function between children with ADHD and normal children.
Method:Twenty children with ADHD and nineteen normal children were sampled, their age range was 7 to 14. They were assessed using Conners scale, K-WISC-Ⅲ, Rey-Kim Memory test for children, Kims Frontal-Executive Function Neuropsychological Test.
Results:There were no significant differences between children with ADHD and normal children in scores of total intelligence, VIQ, PIQ, VCI, POI and FDI in K-WISC-Ⅲ. However, children with ADHD showed lower memory function, especially delayed recall, visual immediate recall, visual delayed recall and memory retention compared to those of normal children. It might be assumed that lower memory function in children with ADHD is affected by retention among memory process(registration-retention-retrieval). And children with ADHD showed poor EIQ, interference index, word fluency/information DI, and FIQ/EIQ DI compared to normal children.
Conclusions:Children with ADHD show poor memory function, especially retention and frontal-executive function, especially interference inhibition and word fluency compared to normal children, although there are no significant differences on measures of intelligence in children with ADHD and normal children. These results suggest that it need to train for children with ADHD to use frontal-executive function, especially behavioral inhibition to enhance the ability and skill of learning.
