Attention deficit hyperactivity disorder (ADHD) is a common childhood neurobehavioral disorder, but its persistence into adulthood is not well established. The present study used two tasks with significant behavioral inhibition and motor control components to test the hypothesis that adult ADHD individuals have deficient motor control and poor behavioral inhibition compared to controls. Preliminary results demonstrate ADHD subjects tend to have slower reaction times and more errors on an inhibitory control task. On motor timing reproduction, both groups tap at an accurate pace, but the ADHD individuals tend to show more variability. Overall, these results suggest that ADHD is a disorder characterized by decreased behavioral inhibition and motor control that persists into adulthood.
