The perception of duration, visually presented, has been studied depending on the visual half-field in which the light stimulations have been presented. The pair of intervals of equal duration, presented for comparison in the 200-1000 ms range, was studied in three different series, in each of which the beginning of the second interval followed accordingly: (a) 10 ms after the beginning of the first interval; (b) after 1/2 of the duration of the first interval; (c) the end of the first interval is at the same time the beginning of the second one. It has been established that two light stimuli of equal duration, presented consecutively in the left and right visual half-fields, are perceived as being different due to their temporal order, provided that the duration of the first interval has elapsed either prior to or at the moment of the onset of the second interval. The temporal order does not affect the subjective duration of overlapping light stimuli. It is possible to assume some kind of hemispheric asymmetry in the duration perception, provided some critical time has elapsed between the end of the first and the beginning of the second intervals. Such an asymmetry cannot be detected in the case of the overlapping intervals studied in the present work.
根据光刺激所呈现的视觉半视野，对视觉呈现的持续时间感知进行了研究。在200 - 1000毫秒范围内呈现用于比较的一对等持续时间间隔，在三个不同系列中进行了研究，在每个系列中，第二个间隔的开始相应地跟随：(a) 在第一个间隔开始后10毫秒；(b) 在第一个间隔持续时间的一半之后；(c) 第一个间隔的结束同时是第二个间隔的开始。已经确定，两个等持续时间的光刺激，连续呈现在左、右视觉半视野中，由于它们的时间顺序，被感知为不同，前提是第一个间隔的持续时间在第二个间隔开始之前或之时已经过去。时间顺序不影响重叠光刺激的主观持续时间。可以假设在持续时间感知中存在某种半球不对称，前提是在第一个间隔结束和第二个间隔开始之间已经经过了一些关键时间。在本研究中所研究的重叠间隔情况下，无法检测到这种不对称。
