| Abstract | To examine the effects of knowledge of results (KR) on the CNV, the vertex EEG was recorded during eight trials of each of five different foreperiods with ISIs of 1, 3, 5, 7 and 10 sec, in each of two conditions, with feedback by knowledge of results (KR) and without (no KR). Foreperiods were presented randomly from trial to trial to reduce the subject's anticipation of S2 onset, but median CNVs were computed in blocks of eight for each ISI. Results showed that peak amplitudes of the CNV increased with KR. Reaction times were shorter with KR than with no KR. However, correlations of peak CNV with reaction time were not significant. It is suggested that motivation by feedback of knowledge of results is a significant factor in CNV genesis. |
