身体周围的空间，其中个人与环境互动被称为perpersonal空间（PPS）。以往的研究报道，PPS具有多感觉的性质。然而，到目前为止，PPS的多感觉性质与个体防御行为之间的关系尚未完全阐明。我们研究了这种关系，通过检查PPS的多感官表示的情况下，身体运动的视觉反馈延迟使用虚拟现实系统。结果表明，身体运动延迟延长了多感觉PPS，这表明身体运动延迟增加了远处物体的潜在威胁，因为有必要更快地准备防御行动。上述研究结果可以解释PPS受人与外界刺激之间的时空关系的调制。这种观点可能提供证据的防御和非防御功能之间的相互作用的多感觉PPS。
The space surrounding the body in which individuals interact with the environment is known as the peripersonal space (PPS). Previous studies have reported that PPS has multisensory nature. However, the relationship between the multisensory nature of PPS and an individuals' defensive actions has not been fully clarified to date. We investigated this relationship by examining the multisensory representation of PPS under situations in which visual feedback of body movements was delayed by using a virtual reality system. The results indicated that body-movement delays extended the multisensory PPS, suggesting that body-movement delays increased the potential threat of distant objects because it was necessary to prepare defensive actions sooner. The previous findings can be interpreted that PPS is modulated by the spatio-temporal relationship between people and external stimuli. This view may provide evidence of interactions between defensive and nondefensive functions of the multisensory PPS.
