先前的研究表明，不相关的声音可以促进视觉视运动的感知。这里通过三个实验研究了单一声音促进运动感知的有效性。向观察者呈现两个离散的光，这两个光在时间上由 0 到 350 毫秒的刺激开始异步分开。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。在灯光之间的时间（和空间）中间呈现的短声音有助于相对于基线（没有声音的灯光）产生运动印象，而在第一个灯光之前或第二个灯光之后或与灯光同时呈现的声音不会影响运动印象。远离视觉显示的声音以及从第一束光开始到第二束光结束的连续声音也会产生促进效应。如果声音是音调序列的一部分，允许在关键视听刺激之前对听觉刺激进行模内感知分组，则不会促进视觉运动感知。总而言之，这些发现与低级视听集成方法一致，在该方法中，感知系统融合了时间上接近的声音和光刺激，从而激发了单个多模态移动物体的印象。 (C) 2008 Elsevier B.V. 保留所有权利。
Previous research has shown that irrelevant sounds can facilitate the perception of visual apparent motion. Here the effectiveness of a single sound to facilitate motion perception was investigated in three experiments. Observers were presented with two discrete lights temporally separated by stimulus onset asynchronies from 0 to 350 ms, After each trial, observers classified their impression of the stimuli using a categorisation system. A short sound presented temporally (and spatially) midway between the lights facilitated the impression of motion relative to baseline (lights without sound), whereas a sound presented either before the first or after the second light or simultaneously with the lights did not affect motion impression. The facilitation effect also occurred with sound presented far from the visual display, as well as with continuous-sound that was started with the first light and terminated with the second light. No facilitation of visual motion perception occurred if the sound was part of a tone sequence that allowed for intramodal perceptual grouping of the auditory stimuli prior to the critical audiovisual stimuli. Taken together, the findings are consistent with a low-level audiovisual integration approach in which the perceptual system merges temporally proximate sound and light stimuli, thereby provoking the impression of a single multimodal moving object.
