We examined the relationship between subcomponents of embodiment and multisensory integration using a mirror box illusion. The participants' left hand was positioned against the mirror, while their right hidden hand was positioned 12″, 6″, or 0″ from the mirror - creating a conflict between visual and proprioceptive estimates of limb position in some conditions. After synchronous tapping, asynchronous tapping, or no movement of both hands, participants gave position estimates for the hidden limb and filled out a brief embodiment questionnaire. We found a relationship between different subcomponents of embodiment and illusory displacement towards the visual estimate. Illusory visual displacement was positively correlated with feelings of deafference in the asynchronous and no movement conditions, whereas it was positive correlated with ratings of visual capture and limb ownership in the synchronous and no movement conditions. These results provide evidence for dissociable contributions of different aspects of embodiment to multisensory integration.
我们使用镜像箱错觉研究了具身化的子成分与多感官整合之间的关系。参与者的左手靠在镜子上，而其隐藏的右手距离镜子12英寸、6英寸或0英寸——在某些情况下会在肢体位置的视觉和本体感觉估计之间产生冲突。在双手同步敲击、异步敲击或不移动之后，参与者对隐藏肢体的位置进行估计，并填写一份简短的具身化问卷。我们发现具身化的不同子成分与向视觉估计的错觉位移之间存在关系。在异步和不移动条件下，错觉视觉位移与去传入感呈正相关，而在同步和不移动条件下，它与视觉捕获和肢体所有权评分呈正相关。这些结果为具身化的不同方面对多感官整合的可分离贡献提供了证据。
