In judging brief stimulus duration, change of the number of dark dots from three to one resulted in underestimation, while similar change from three to five resulted in overestimation. Such a trend of temporal judgment was accentuated when the change was less frequent, demonstrating a contrast effect. But the analogous contrast effect was also obtained when the stimulus duration itself was changed.
