在许多感官维度中，可以发现对感知事件特征的同化。在本研究中，我们考察了同化是否也出现在时间知觉中，采用了短于300ms的以短音调为标志的时间间隔。在实验1中，我们测量了相邻的两个空时间间隔T1和T2的主观相等点。当T1和T2的差值较小时，知觉时程相互接近。也就是说，发生了双边同化。在实验2中，我们以比实验1更小的步长和更宽的持续时间范围测量了T1的主观等价点。我们发现，当T1比T2略短时，T1被轻微高估，而当它略长于T2时，0被轻微低估。高估和低估被认为是典型的同化。结果还表明，当T1和T2之间的差异超过-80时，对T1的感知从同化转变为对比
In many sensory dimensions, assimilation of characteristics of perceived events can be found. In the present study, we examined whether assimilation appeared also in time perception, employing time intervals shorter than 300 ms marked by tone bursts. In Experiment 1, we measured points of subjective equality of two neighboring empty time intervals, t1 and t2. The perceived durations approached each other when the difference between t1 and t2 was small. That is, bilateral assimilation took place. In Experiment 2, we measured points of subjective equality of t1 in smaller steps and across a wider durational range than in Experiment 1. We found that t1 was overestimated slightly when it was a bit shorter than t2, and 0 was underestimated slightly when it was a bit longer than t2. The overestimation and the underestimation were considered as typical assimilation. The results also showed that the perception of t1 changed from assimilation to contrast when the difference between t1 and t2 exceeded the range -80
