虚拟现实(VR)中的实施感通常被理解为一个人的身体被虚拟对应物取代的主观体验,通常是在化身的身体,从第一人称视角看,像一个人的身体一样移动。实施例也可以在其他情况下经历(例如,在第三人称视角)或不精确或扭曲的视觉电机耦合。此外,据观察,在化身运动的小的或渐进的时间和空间操纵的各种情况下,参与者可以自发地跟随化身显示的运动。目前的工作调查是否,在某些特定情况下,即使出现较大的运动差异,参与者也会遵循他们的化身所做的事情,从而扩展了对自我化身追随者效应的理解范围,超越了运动或速度操纵的细微变化。我们进行了一项实验研究,其中我们引入了在特定时间执行哪种运动的不确定性,并在他们的化身显示他们不正确的运动后分析了参与者的运动和主观反馈。结果表明,如果有疑问,参与者受到化身动作的影响,导致他们执行该特定错误的频率比正常情况多两倍。重要的是,实施例得分的结果指示参与者在那些时间经历了与他们的化身的分离。总的来说,这些观察结果不仅证明了可能引发参与者遵循其化身的指导进行大型运动扭曲的情况,尽管他们意识到化身运动的中断及其对他们选择的可能影响,and,重要的是,体现的认知机制如何深深植根于拥有身体的必要性。
The sense of embodiment in virtual reality (VR) is commonly understood as the subjective experience that one\'s physical body is substituted by a virtual counterpart, and is typically achieved when the avatar\'s body, seen from a first-person view, moves like one\'s physical body. Embodiment can also be experienced in other circumstances (e.g., in third-person view) or with imprecise or distorted visuo-motor coupling. It was moreover observed, in various cases of small or progressive temporal and spatial manipulations of avatars\' movements, that participants may spontaneously follow the
movement shown by the avatar. The present work investigates whether, in some specific contexts, participants would follow what their avatar does even when large
movement discrepancies occur, thereby extending the scope of understanding of the self-avatar follower effect beyond subtle changes of motion or speed manipulations. We conducted an experimental study in which we introduced uncertainty about which
movement to perform at specific times and analyzed participants\' movements and subjective feedback after their avatar showed them an incorrect
movement. Results show that, when in doubt, participants were influenced by their avatar\'s movements, leading them to perform that particular error twice more often than normal. Importantly, results of the embodiment score indicate that participants experienced a dissociation with their avatar at those times. Overall, these observations not only demonstrate the possibility of provoking situations in which participants follow the guidance of their avatar for large motor distortions, despite their awareness about the avatar
movement disruption and on the possible influence it had on their choice, and, importantly, exemplify how the cognitive mechanism of embodiment is deeply rooted in the necessity of having a body.
