In visual competition, the perception of ambiguous visual patterns changes spontaneously. Although the process causing this perceptual alternation remains unclear, recent evidence suggests various types of non-visual influences in resolving visual ambiguity. In the present study, we investigated cross-modal modulation of a transient stimulus on visual perceptual stability (i.e., alternation frequency). Participants observed an ambiguous visual figure and reported their perceptual alternations. Concurrently, we presented visual and auditory transient events. The results revealed that the auditory as well as visual transient events destabilize the current perception (i.e., they increase alternation frequency) around 0.5-1.5 s after the event. In addition, the magnitudes of auditory and visual effects were comparable and positively correlated within participants. These results suggest that the visual perceptual stability can be under the influence of processes that are shared by different senses.
在视觉竞争中，模糊视觉模式的感知会自发变化。尽管导致这种感知交替的过程尚不清楚，但最近的证据表明，在解决视觉模糊性方面存在各种非视觉影响。在本研究中，我们调查了瞬态刺激对视觉感知稳定性（即交替频率）的跨模态调制。参与者观察一个模糊的视觉图形并报告他们的感知交替。同时，我们呈现视觉和听觉瞬态事件。结果显示，听觉和视觉瞬态事件都会在事件发生后约0.5 - 1.5秒使当前感知不稳定（即它们增加交替频率）。此外，听觉和视觉效应的大小在参与者内部具有可比性且呈正相关。这些结果表明，视觉感知稳定性可能受到不同感官共享的过程的影响。
