One's own face and gaze are never seen directly but only in a mirror. Yet, these stimuli capture attention more powerfully than others' face and gaze, suggesting the self is special for brain and behavior. Synchronous touches felt on one's own and seen on the face of others induce the sensation of including others in one's own face (enfacement). We demonstrate that enfacement may also reduce the overwhelming distracting power of self-gaze. This effect, hereafter called 'engazement', depends on the perceived physical attractiveness and inner beauty of the pair partner. Thus, we highlight for the first time the close link between enfacement and engazement by showing that changes of the self-face representation induced by facial visuo-tactile stimulation extend to gaze following, a separate process likely underpinned by different neural substrates. Moreover, although gaze following is a largely automatic, engazement is penetrable to the influence of social variables, such as positive interpersonal perception.
人们永远无法直接看到自己的脸和目光，只能通过镜子看到。然而，这些刺激比他人的脸和目光更能强烈地吸引注意力，这表明自我在大脑和行为方面具有特殊性。自己感受到的同步触摸以及在他人脸上看到的同步触摸会引发将他人纳入自己脸部的感觉（脸部化）。我们证明，脸部化也可能降低自我目光带来的压倒性干扰力。这种效应，在此后称为“目光化”，取决于对伴侣的感知身体吸引力和内在美。因此，我们首次通过表明面部视觉触觉刺激引起的自我面部表征变化扩展到目光追随，突出了脸部化和目光化之间的紧密联系，目光追随是一个可能由不同神经基质支持的独立过程。此外，尽管目光追随在很大程度上是自动的，但目光化会受到社会变量的影响，比如积极的人际感知。
