Abstract: The inhibition deficits of ADHD were explored by the nonselective stop signal task in the most previous studies.But it is still not explicit that which causes the inhibition deficit found in stop task,the race between execution and response inhibition or the response variability.The more accurate selective stop signal task was used to explore the deficit of ADHD in this research.It was found that the ADHD group made more commission errors than controls,and they have larger response variability than controls,but there is no difference in the processing speed.We suggest that the disinhibition of ADHD is not caused by the slow cognition tempo rather than by the failure to maintain the optimal arousal state.
