人类通常会体验到意识自我局限于其身体边界内。这种空间统一性可能会在某些神经系统疾病（例如灵魂出窍）中被破坏，从而导致身体自我意识的显着紊乱。根据这些临床数据，我们设计了一个实验，利用虚拟现实中相互冲突的视觉体感输入来破坏自我和身体之间的空间统一。我们发现，在多感官冲突期间，参与者感觉他们面前看到的虚拟身体就是他们自己的身体，并将自己错误地定位于虚拟身体，处于他们身体边界之外的位置。我们的结果表明，空间统一和身体自我意识可以通过实验进行研究，并且基于身体信息的多感官和认知处理。
Humans normally experience the conscious self as localized within their bodily borders. This spatial unity may break down in certain neurological conditions such as out-of-body experiences, leading to a striking disturbance of bodily self-consciousness. On the basis of these clinical data, we designed an experiment that uses conflicting visual-somatosensory input in virtual reality to disrupt the spatial unity between the self and the body. We found that during multisensory conflict, participants felt as if a virtual body seen in front of them was their own body and mislocalized themselves toward the virtual body, to a position outside their bodily borders. Our results indicate that spatial unity and bodily self-consciousness can be studied experimentally and are based on multisensory and cognitive processing of bodily information.
