The perception of dynamic objects is sometimes biased. For example, localizing a moving object after it has disappeared results in a perceptual shift in the direction of motion, a bias known as representational momentum. We investigated whether the temporal characteristics of an irrelevant, spatially uninformative vibrotactile stimulus bias the perceived location of a visual target. In two visuotactile experiments, participants judged the final location of a dynamic, visual target. Simultaneously, a continuous (starting with the onset of the visual target, Experiments 1 and 2) or brief (33-ms stimulation, Experiment 2) vibrotactile stimulus (at the palm of participant’s hands) was presented, and the offset disparity between the visual target and tactile stimulation was systematically varied. The results indicate a cross-modal influence of tactile stimulation on the perceived final location of the visual target. Closer inspection of the nature of this cross-modal influence, observed here for the first time, reveals that the vibrotactile stimulus was likely just taken as a temporal cue regarding the offset of the visual target, but no strong interaction and combined processing of the two stimuli occurred. The present results are related to similar cross-modal temporal illusions and current accounts of multisensory perception, integration, and cross-modal facilitation.

对动态物体的感知有时会产生偏差。例如，在移动物体消失后对其进行定位会导致在运动方向上发生感知偏移，这种偏移称为代表性动量。我们调查了不相关的，空间上无信息的触觉刺激的时间特征是否偏向了视觉目标的感知位置。在两个触觉实验中，参与者判断了动态视觉目标的最终位置。同时，提出了连续的（从视觉目标的发作开始，实验1和2）或短暂的（33毫秒刺激，实验2）振动触觉刺激（在参与者的手掌上），并且视觉之间的偏移差异目标和触觉刺激是系统地变化的。结果表明，触觉刺激对视觉目标的感知最终位置产生了跨模式影响。首次在这里仔细观察了这种交叉模式影响的性质，揭示了触觉刺激可能只是作为视觉目标偏移的时间提示，但没有发生强烈的相互作用和两种刺激的联合处理。目前的结果与类似的跨模式时间错觉和多感官感知，整合和跨模式促进的当前描述有关。
