In the "enfacement" illusion seeing an unfamiliar face being touched at the same time as one's own face evokes changes in self-face recognition. We investigated the contribution of proprioceptive and motor signals derived from self-generated actions in the sensory-driven malleability of self-other boundaries during the "enfacement" illusion. Changes in self-face recognition during active- and passive-touch interpersonal visuo-tactile stimulation were quantified by means of psychophysical and psychometric tasks. Active- and passive-touch evoked comparable changes in the categorical boundaries of self-other distinction, changing the extent to which the other is assimilated into the mental self-representation. Actively touching or simply feeling touch on one's own face with concurrent observed touch on someone else's face seems to elicit comparable changes in self-recognition, suggesting that afferent input might be sufficient for updating one's body-image, although some components of the experience of self-identification seem to be more affected by passive- than by active-touch.
在“面对”错觉中，当看到一个陌生的面孔同时被触摸到自己的脸时，会引起自我面孔识别的变化。我们研究了在“面对”错觉中，源自自我产生的动作的本体感觉和运动信号对自我-他人边界的感觉驱动可塑的贡献。通过心理物理学和心理测量任务来量化主动和被动触摸人际视触觉刺激期间自我面孔识别的变化。主动触摸和被动触摸都会引起自我与他人区分的范畴边界的类似变化，改变了他人被同化到心理自我表象的程度。主动触摸或仅仅是在观察到别人的脸被触摸时触摸自己的脸，似乎会引起自我识别的类似变化，这表明传入的输入可能足以更新自己的身体形象，尽管自我认同的某些体验成分似乎更容易受到被动触摸而不是主动触摸的影响。
