裂变错觉是由多感官（视听）整合引起的。在本研究中，我们假设知觉效率影响裂变错觉的速度，因为这种错觉发生在一个短的时间范围内，通过整合的视觉和听觉信息。本研究通过呈现不同复杂程度的视觉模式，考察知觉效率对裂变错觉的影响。结果表明，当使用更复杂的视觉模式时，更难诱发裂变错觉。在第一视觉刺激和第二听觉刺激之间，图形对错觉的影响因刺激起始时间的不同而不同。这些结果表明，当第一个视觉刺激的感知过程完成，并与第一个哔哔声在第二个哔哔声呈现之前整合时，裂变错觉有更高的概率发生。因此，视听整合受到物理刺激的感知效率的影响。
The fission illusion is induced by multisensory (audio-visual) integration. In the present study, we assume that perceptual efficiency affects the fission illusion’s rate because this illusion occurs in a short temporal range through the integration of visual and auditory information. The present study examined the effect of perceptual efficiency on the fission illusion by presenting visual patterns with various degrees of complexity. The results indicated that it was more difficult to induce the fission illusion when more complex visual patterns were used. The effect of pattern on the illusion differed according to the stimulus onset asynchrony between the first visual stimulus and the second auditory stimulus. These results suggest that the fission illusion has a higher probability of occurring when the perceptual process of the first visual stimulus is completed and integrated with the first beep before the presentation of the second beep. Thus, the audio-visual integration is affected by the perceptual efficiency of the physical stimuli.
