The present experiment was designed to investigate the factors affecting the resolution of the contingent negative variation (CNV). In the first session, 11 subjects were tested in a standard CNV paradigm. These subjects were then tested in a probability learning paradigm in which a red or green feedback light informed the subjects whether their choice of response was correct or incorrect. The feedback stimuli were presented.75, 1, and 1.5 sec after the imperative stimulus. The results showed that the resolution of CNV occurred immediately after the motor response in the standard CNV paradigm. In the feedback paradigm, on the other hand, the resolution of CNV occurred only after the feedback stimulus. The results suggested that the resolution of CNV is contingent upon the psychological state of completion initiated by the feedback stimulus rather than the motor response.
