We investigated effect of various tasks on contingent negative variation (CNV) resolution processes. Above all, it is investigated how the existence of motor preparation, of motor response and of stimulus discrimination on imperative stimulus affects CNV resolution. The subjects were 16 normal students. Five tasks were performed by the subjects. As a result, CNV resolution time was prolonged in the simple motor task compared to other tasks. The appearance of component like P300 on S_2 was unclear. But in other conditions, component like P300 on S_2 was found. Moreover it is found that the appearance of component like P300 affected CNV resolution. A significant difference in the CNV resolution was found between discrimination motor task and discrimination mental task. Based on these results, it is concluded that CNV resolution was depended on the discrimination of S_2 stimulus, but did not on the existence of motor preparation or motor response.
