This investigation was carried out to know whether the same kind of results as previously reported (Sato, 1972) could be obtained or not, even when the nature of the stimuli changes from flickering light to intermittent sound and white noise. Results: 1) The curve, in which variance indices of the correct responses of the task given Ss were plotted against the frequency of flutter, showed two peaks for all Ss. The one peak was at 2Hz, and the other at 12Hz. In the flickering light exp. previously reported, the Ss were divided into two groups, each group having only one peak on this curve. 2) All of the flutter and noise stimuli were estimated to be unpleasant on pleasant-unpleasant rating scales by the majority of Ss. But small number of Ss estimated them to be pleasant in every frequency. 3) The relationship between response variability of the task and the feeling caused by the flutter and the noise was only slight.
