In the illusory body ownership, humans feel as if a rubber hand or an avatar in a virtual environment is their own body through visual-tactile synchronization or visual-motor synchronization. Despite the onset time and duration of illusory body ownership has been investigated, it is not clear how the onset time and duration change when a part of the body is missing from the full-body. In this study, we investigated the completeness of the full-body for the illusion onset and duration by comparing the following conditions: complete avatar, avatar missing hands and feet, and avatar with hands and feet only. Our results suggest that avatar hands and feet only shorten the duration of the illusion, and missing body parts, such as only hands and feet or no hands and feet, reduce the sense of body ownership and of agency. However, the effects of avatar completeness on the onset time are unclear, and no conclusions can be made in either direction based on the current findings.
在虚幻身体拥有感中，通过视觉-触觉同步或视觉-运动同步，人类感觉橡胶手或虚拟环境中的化身是自己的身体。尽管已经研究了虚幻身体拥有感的起始时间和持续时间，但当身体的一部分缺失时，起始时间和持续时间如何变化尚不清楚。在这项研究中，我们通过比较以下条件来研究完整的全身对幻觉起始和持续时间的影响：完整的化身、缺少手和脚的化身、只有手和脚的化身。我们的结果表明，只有手和脚的化身缩短了幻觉的持续时间，而缺失身体部分（如只有手和脚或没有手和脚）会降低身体所有权和代理感。然而，化身完整性对起始时间的影响尚不清楚，根据目前的发现，无法得出任何结论。
