Abstract

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.

视觉自我运动反馈影响虚拟现实中的自我感觉
我们评估了自我运动如何影响自我的视觉表征。我们构建了一个新颖的虚拟现实实验,系统地改变化身的动作和生物性别。参与者会看到一对头像,在视觉上代表参与者("自我头像")或另一个人("相反头像")。头像的运动要么与参与者的运动相对应,要么与参与者的运动脱钩。结果表明,被试(i)认同 "自己的头像",而不是 "对面的头像";(ii)认同与自己的运动一致的头像,而不是运动不一致的头像;重要的是(iii)当对面头像的运动与自己的运动一致时,被试认同 "对面的头像",而不是 "自己的头像"。我们的研究结果表明,自我运动和生物性别都与身体图式和身体形象有关,而且自下而上的自我运动视觉反馈对自我意识尤为重要,能够超越生物性别等自上而下的自我认同因素。

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
