Here we demonstrate that the perceptual system adapts to tactile-visual temporal asynchronies (i.e., temporal recalibration). Participants were exposed to a train of tactile and visual stimuli with a constant time lag (either -100ms, 0ms, or 100ms; with negative values indicating that the tactile stimulus came first). Following exposure, they were presented tactile-visual test stimulus pairs and judged whether the tactile or the visual stimulus was presented first (Temporal Order Judgement). Results show that subjective simultaneity (the PSS) was shifted in the direction of the exposure lag. The results fit reports on auditory-visual temporal recalibration and indicate that the brain adapts to temporal incongruencies between modalities in general.
在此我们证明，感知系统会适应触觉-视觉时间异步性（即时间重新校准）。参与者暴露于一系列具有恒定时间延迟（-100毫秒、0毫秒或100毫秒；负值表示触觉刺激先出现）的触觉和视觉刺激中。暴露之后，向他们呈现触觉-视觉测试刺激对，并判断是触觉刺激还是视觉刺激先呈现（时间顺序判断）。结果表明，主观同时性（PSS）朝着暴露延迟的方向发生了偏移。这些结果与关于听觉-视觉时间重新校准的报告相符，并表明大脑通常会适应不同感觉模态之间的时间不一致。
