我们进行了一个实验，在这个实验中，一个人自己身体部位之间的视觉不连续性扰乱了身体的统一性，并消除了主观和有意识的剥夺。以前的研究已经证明，从第一人称的角度来看，对外部物体的所有权感会减少。相反，本研究表明，人们可以从第三人称的角度感受到对自己身体的明确剥夺。目前的实验向参与者展示了他们自己身体的实时侧面图像。在试验过程中，他们在以下限制条件下移动和观察他们的手臂：在“隐藏”条件下，肘部隐藏在上身后面，掩盖了手臂和上身之间的平滑连接。在“展示”状态下手肘被展示在上半身的前方，以更好地展示平滑的连接。问卷调查结果表明，参与者感到失去了他们的武器，而保留机构。因此，这个实验为身体意识提供了新的视角。
We conducted an experiment in which visual discontinuity between one’s own body parts disturbs the unity of the body and elicits subjective and conscious disownership. Previous studies have demonstrated a decrease in feelings of ownership over an external object from a first-person viewpoint. In contrast, the present study suggests that people can feel explicit disownership of their own body from a third-person viewpoint. The current experiment presented participants with live, lateral images of their own body. During the trial, they moved and observed their arms within the following restrictions: In the “hide” condition, an elbow was hidden behind the upper body, obscuring the smooth connection between the arm and upper body. In the “display” condition, the elbow was displayed in front of the upper body to better display the smooth connection. Questionnaire results demonstrated that the participants felt disownership of their arms while retaining agency. Therefore, this experiment sheds new light on bodily awareness.
