当两个离散的刺激快速相继出现时，观察者通常会报告领先刺激向滞后刺激的移动。本研究的目的是探讨无关声音对视觉表观运动错觉的跨通道效应。观察者被呈现两个视觉刺激，这两个视觉刺激在时间上被从0到350INS的刺激间开始间隔分开。每次试验后，观察者使用分类系统对他们对刺激的印象进行分类。视觉刺激之间的短声呈现有利于相对于基线的表观运动的印象(无声音的视觉刺激)，而在第一次和第二次视觉刺激之前和之后呈现的声音以及同时呈现的声音降低了运动印象。结果表明，不相关声音的时间结构对视觉表观运动的影响，这是根据一种相关的多感官现象--临时性口技--来讨论的，该现象假设声音可以在时间维度上吸引光线。
When two discrete stimuli are presented in rapid succession, observers typically report a movement of the lead stimulus toward the lag stimulus. The object of this study was to investigate crossmodal effects of irrelevant sounds on this illusion of visual apparent motion. Observers were presented with two visual stimuli that were temporally separated by interstimulus onset intervals from 0 to 350 ins. After each trial, observers classified their impression of the stimuli using a categorisation system. The presentation of short sounds intervening between the visual stimuli facilitated the impression of apparent motion relative to baseline (visual stimuli without sounds), whereas sounds presented before the first and after the second visual stimulus as well as simultaneously presented sounds reduced the motion impression. The results demonstrate an effect of the temporal structure of irrelevant sounds on visual apparent motion that is discussed in light of a related multisensory phenomenon, 'temporal ventriloquism, on the assumption that sounds can attract lights in the temporal dimension.
