In the rubber hand illusion (RHI), simultaneous brush stroking of a subject’s hidden hand and a visible rubber hand induces a transient illusion of the latter to “feel like it’s my hand” and a proprioceptive drift of the hidden own hand toward the rubber hand. Recent accounts of the RHI have suggested that the illusion would only occur if weighting of conflicting sensory information and their subsequent integration results in a statistically plausible compromise. In three different experiments, we investigated the role of distance between the two hands as well as their proximity to the body’s midline in influencing the occurrence of the illusion. Overall, the results suggest that the illusion is abolished when placing the two hands apart, therefore increasing the mismatch between the visual and proprioceptive modality, whereas the proximity of the two hands to the body’s midline plays only a minor role on the subjective report of the illusion. This might be driven by the response properties of visuotactile bimodal cells encoding the peripersonal space around the hand.

在橡胶手错觉（RHI）中，同时用刷子抚摸对象的隐藏手和可见的橡胶手会导致后者的短暂错觉“感觉就像是我的手”，并且隐藏的自己的手向橡胶手的本体感觉漂移。RHI的最新研究表明，只有在冲突的感官信息的权重及其随后的整合导致统计上合理的情况下，这种错觉才会发生妥协。在三个不同的实验中，我们调查了两只手之间的距离以及它们与身体中线的接近度在影响错觉发生中的作用。总体而言，结果表明，将两只手分开放置会消除错觉，因此会增加视觉和本体感受模态之间的不匹配，而两只手与身体中线的接近度仅在主观报告中起次要作用。错觉。这可能是由编码手周围人周围空间的触觉双峰细胞的响应特性驱动的。
