Integrating dynamic information across the senses is crucial to survival. However, most laboratory studies have only examined sensory integration for static events. Here we demonstrate that strong crossmodal integration can also occur for an emergent attribute of dynamic arrays, specifically the direction of apparent motion. The results of the present study show that the perceived direction of auditory apparent motion is strongly modulated by apparent motion in vision, and that both spatial and temporal factors play a significant role in this crossmodal effect. We also demonstrate that a split-brain patient who does not perceive visual apparent motion across the midline is immune to this audiovisual dynamic capture effect, highlighting the importance of motion being experienced in order for this new multisensory illusion to occur.
整合跨感官的动态信息对生存至关重要。然而,大多数实验室研究仅考察了静态事件的感官整合。在此我们证明,对于动态阵列的一个新兴属性,特别是表观运动的方向,也会发生强烈的跨模态整合。本研究结果表明,视觉中的表观运动会强烈调节听觉表观运动的感知方向,并且空间和时间因素在这种跨模态效应中都起着重要作用。我们还证明,一名无法感知跨越中线的视觉表观运动的裂脑患者对这种视听动态捕获效应具有免疫力,这突出了为使这种新的多感官错觉发生而体验运动的重要性。
