Interference and Cognitive Inhibition in Children with ADHD Using Stroop Task
M. Shin
This study was conducted to examine a mechanism of cognitive inhibition in children with Attention Deficit Hyperactivity Disorder (ADHD) by using a negative priming Stroop task. The Stroop task was administered to children with ADHD and controls under two presentation times: 100 ms and 500 ms. In the interference condition, children with ADHD took more time and more errors as compared to normal children under 500 ms. More importantly, it was hypothesized that, relative to normal children, children with ADHD would show reduced negative priming. Results confirmed this hypothesis under the 500 ms presentation time condition.

Key words: ADHD (Attention Deficit Hyperactivity Disorder), Stroop task, cognitive inhibition, negative priming
