哲学和心理学中的一个经典问题是，一个人的身体感觉是否会影响一个人对世界的视觉感知。一些理论家认为，我们自己的身体在大小和距离的视觉感知中起着基本的参考作用，尽管缺乏令人信服的实验证据来证明这一假设。相比之下，现代教科书通常通过组合来自不同视觉线索的信息来解释对物体大小和距离的感知。在这里，我们描述了全身错觉，其中受试者体验到一个娃娃的身体（80厘米或30厘米）和一个巨人的身体（400厘米）的所有权，并使用这些作为工具来证明，一个人的感觉自己的身体的大小直接影响的感知对象的大小和距离。这些影响在十个单独的实验中进行了量化，包括补充口头，问卷调查，手动，步行和生理措施。当参与者将微小的身体体验为自己的身体时，他们感知到的物体更大更远，而当他们体验到大身体错觉时，他们感知到的物体更小更近。重要的是，尽管视网膜输入相同，但与所有权被破坏的控制条件相比，当参与者体验到对人造身体的所有权时，这种“身体大小效应”更大。这些发现是非常重要的，因为它们表明了身体空间和外部空间的表征之间的因果关系。因此，我们自己的身体大小影响我们如何感知世界。
A classical question in philosophy and psychology is if the sense of one's body influences how one visually perceives the world. Several theoreticians have suggested that our own body serves as a fundamental reference in visual perception of sizes and distances, although compelling experimental evidence for this hypothesis is lacking. In contrast, modern textbooks typically explain the perception of object size and distance by the combination of information from different visual cues. Here, we describe full body illusions in which subjects experience the ownership of a doll's body (80 cm or 30 cm) and a giant's body (400 cm) and use these as tools to demonstrate that the size of one's sensed own body directly influences the perception of object size and distance. These effects were quantified in ten separate experiments with complementary verbal, questionnaire, manual, walking, and physiological measures. When participants experienced the tiny body as their own, they perceived objects to be larger and farther away, and when they experienced the large-body illusion, they perceived objects to be smaller and nearer. Importantly, despite identical retinal input, this “body size effect” was greater when the participants experienced a sense of ownership of the artificial bodies compared to a control condition in which ownership was disrupted. These findings are fundamentally important as they suggest a causal relationship between the representations of body space and external space. Thus, our own body size affects how we perceive the world.
