Although visual perception traditionally has been considered to be impenetrable by non-visual information, there are a rising number of reports discussing cross-modal influences on visual perception. In two experiments, we investigated how coinciding vibrotactile stimulation affects the perception of two discs that move toward each other, superimpose in the center of the screen, and then move apart. Whereas two discs streaming past each other was the dominant impression when the visual event was presented in isolation, a brief coinciding vibrotactile stimulation at the moment of overlap biased the visual impression toward two discs bouncing off each other (Experiment 1). Further, the vibrotactile stimulation actually changed perceptual processing by reducing the amount of perceived overlap between the discs (Experiment 2), which has been demonstrated to be associated with a higher proportion of bouncing impressions. We propose that tactile-induced quantitative changes in the visual percept might alter the quality of the visual percept (from streaming to bouncing), thereby adding to the understanding of how cross-modal information interacts with early visual perception and how this interaction influences subsequent visual impressions.
尽管传统上视觉感知被认为不受非视觉信息的影响，但现在有越来越多的报告讨论跨模态对视觉感知的影响。在两个实验中，我们研究了同时进行的振动触觉刺激如何影响两个相互靠近、在屏幕中心叠加然后分开的圆盘的感知。当视觉事件单独呈现时，两个圆盘相互流过是主要的印象，而在重叠瞬间短暂的同时进行的振动触觉刺激会使视觉印象偏向于两个圆盘相互反弹（实验1）。此外，振动触觉刺激实际上通过减少圆盘之间的感知重叠量改变了感知处理（实验2），这已被证明与更高比例的反弹印象相关。我们提出，触觉引起的视觉感知的定量变化可能会改变视觉感知的质量（从流动到反弹），从而增进对跨模态信息如何与早期视觉感知相互作用以及这种相互作用如何影响后续视觉印象的理解。
