We report a distortion of subjective time perception in which the duration of a first interval is perceived to be longer than the succeeding interval of the same duration. The amount of time expansion depends on the onset type defining the first interval. When a stimulus appears abruptly, its duration is perceived to be longer than when it appears following a stationary array. The difference in the processing time for the stimulus onset and motion onset, measured as reaction times, agrees with the difference in time expansion. Our results suggest that initial transient responses for a visual onset serve as a temporal marker for time estimation, and a systematic change in the processing time for onsets affects perceived time.
我们报告了一种主观时间感知的扭曲现象，即第一个间隔的持续时间被感知为比随后相同持续时间的间隔更长。时间膨胀的程度取决于定义第一个间隔的起始类型。当刺激突然出现时，其持续时间被感知为比在静止阵列之后出现时更长。以反应时间衡量的刺激起始和运动起始的处理时间差异，与时间膨胀的差异一致。我们的结果表明，视觉起始的初始瞬态反应作为时间估计的时间标记，并且起始处理时间的系统性变化会影响感知时间。
