Objective. This study assessed the relation of response inhibition with inattention and hyperactivity–impulsivity. Method. The stop signal task was employed to investigate inhibitory control in 76 children with symptoms of inattention and/or hyperactivity–impulsivity and 48 normal control subjects. The Rating Scale for teachers, which measures the intensity of hyperactivity–impulsivity and inattention, was completed for each child. Results. Response inhibition deficit was found in children with symptoms of inattention alone or both inattention and hyperactivity–impulsivity, but not in children with hyperactive–impulsive symptoms alone. Stepwise regression indicated that distractibility–fatigability is the best predictor of the stop signal reaction time. Conclusions. Symptoms of inattention, rather than symptoms of hyperactivity–impulsivity, are associated with the response inhibition impairment.
