The effects of spatial frequency and temporal transition of sine-wave grating onset and offset were assessed using measures of reaction time, visual persistence, and temporal order judgements. The stimuli were lateralized fields, separated by 1 degree of visual angle. Slow temporal transition resulted in significantly poorer performance than did abrupt onset and offset, but spatial frequency had a minimal effect. Thus, the latency, temporal resolution, and temporal ordering of events are mediated by a mechanism that is sensitive to abrupt temporal transients. The stimulus conditions employed did not result in a shift in the point of subjective simultaneity.
使用反应时间、视觉暂留和时间顺序判断等指标，评估了正弦波光栅起始和结束时的空间频率和时间转换的影响。刺激是偏心视野，相隔1度视角。与突然的起始和结束相比，缓慢的时间转换导致明显较差的表现，但空间频率的影响最小。因此，事件的潜伏期、时间分辨率和时间排序由对突然的时间瞬变敏感的机制介导。所采用的刺激条件并未导致主观同时性点的偏移。
