Interference control in children with attention deficit/hyperactivity disorder.

The view that Attention Deficit/Hyperactivity Disorder (ADHD) is associated with a diminished ability to control interference is controversial and based exclusively on results of (verbal)-visual interference tasks, primarily the Stroop Color Word task. The present study compares medication-naïve children with ADHD (n = 35 and n = 51 in Experiments 1 and 2, respectively) with normal controls (n = 26 and n = 32, respectively) on two interference tasks to assess interference control in both the auditory and the visual modality: an Auditory Stroop task and a Simon task. Both groups showed reliable but equal degrees of interference on both tasks, suggesting that children with ADHD do not differ from normal controls in their ability to control interference in either modality.
