Abstract
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.
