There is a growing consensus that our most fundamental sense of self is structured by the ongoing integration of sensory and motor information related to our own body. Depersonalisation (DP) is an intriguing form of altered subjective experience in which people report feelings of unreality and detachment from their sense of self. The current study used the visual remapping of touch (VRT) paradigm to explore self-bias in visual-tactile integration in non-clinical participants reporting high and low levels of depersonalisation experiences. We found that the high-DP group showed an increased overall VRT effect but a no-self-face bias, instead showing a greater VRT effect when observing the face of another person. In addition, across all participants, self-bias was negatively predicted by the occurrence of anomalous body experiences. These results indicate disrupted integration of tactile and visual representations of the bodily self in those experiencing high levels of DP and provide greater understanding of how disruptions in multisensory perception of the self may underlie the phenomenology of depersonalisation.

分离的自我：研究人格的视觉重映射中去个性化对自我偏见的影响。

越来越多的共识认为，我们最基本的自我意识是由与我们自身身体相关的感觉和运动信息的持续整合所构成的。去人格化（DP）是改变主观体验的一种有趣形式，其中人们报告不真实和与自己的自我感觉脱节的感觉。当前的研究使用视觉重贴触摸（VRT）范式来探索在非临床参与者中报告高和低水平的去个性化体验的视觉-触觉整合中的自我偏见。我们发现，高DP组显示出总体VRT效果增强，但没有自我面孔的偏见，而在观察另一个人的面部时显示出更大的VRT效果。此外，在所有参与者中，自我偏向被异常身体经历的发生否定地预测。
