We assessed how self-motion affects the visual representation of the self. We constructed a novel virtual-reality experiment that systematically varied an avatar's motion and also biological sex. Participants were presented with pairs of avatars that visually represented the participant ('self-avatar'), or another person ('opposite avatar'). Avatar motion either corresponded with the participant's motion, or was decoupled from the participant's motion. The results show that participants identified with (i) 'self-avatars' over 'opposite-avatars', (ii) avatars moving congruently with self-motion over incongruent motion, and importantly (iii) with the 'opposite avatar' over the 'self-avatar' when the opposite avatar's motion was congruent with self-motion. Our results suggest that both self-motion and biological sex are relevant to the body schema and body image and that congruent bottom-up visual feedback of self-motion is particularly important for the sense of self and capable of overriding top-down self-identification factors such as biological sex.

视觉自我运动反馈会影响虚拟现实中的自我感。

我们评估了自我运动如何影响自我的视觉表现。我们构建了一个新颖的虚拟现实实验，该实验系统地改变了化身的动作以及生物性别。向参与者展示了可视化代表参与者（“自我头像”）或另一个人（“相对头像”）的成对头像。阿凡达的动作要么与参与者的动作相对应，要么与参与者的动作分离。结果显示，参与者识别为（i）相对于“对立头像”为“自我头像”，（ii）对应于不相称运动与自身运动一致地移动的头像，并且重要的是（iii）相对于“相反的头像”为“相反的头像”自我化身”，即相反的化身的运动与自我运动相吻合。
