How does the brain switch between the integration and segregation of multiple sensory signals? We tried to answer the question in terms of temporal perception. First, we tested the hypothesis that the spatial congruency affects the integration. Participants were asked to judge the subjective temporal order of visual and tactile stimuli whose spatial locations were congruent or incongruent. Lag adaptation was observed in the congruent condition, while Bayesian calibration was observed in the incongruent condition. This suggests that the spatial congruency contributes to the integration. Second, we tested the hypothesis that the recognition of self and others affects the integration. We discovered that the probability of subjective simultaneity increases when visuotactile signals belong to the participant's own body. Taken together, the brain switches the integration and segregation depending on whether the sensory signals originate from a single source.

大脑如何在多种感觉信号的整合和分离之间切换？我们试图从时间感知的角度来回答这个问题。首先，我们检验了空间一致性影响整合的假设。被试被要求判断空间位置一致或不一致的视觉和触觉刺激的主观时间顺序。在一致条件下观察到滞后适应，而在不一致条件下观察到贝叶斯校准。这表明，空间一致性有助于整合。其次，我们检验了自我和他人的认知影响整合的假设。我们发现，当视觉触觉信号属于参与者自己的身体时，主观不确定性的概率增加。总之，大脑根据感觉信号是否来自单一来源来切换整合和分离。
