Methods 70 childr en with ADHDand 70 normal children were selected to assess the v isual and auditory reaction time by using the computer reaction time test system.
Results ADHDchildren were compared with normal controls, and there were not obv iously differences on reaction time of visual and auditory reactio n time tests(P > 0.05);obvious differences only existed on errors rate of visual and auditory reaction time teste(P < 0.05 or P < 0.01).
