身体错觉提供了一种实验方法来调查自己的身体感觉的起源和功能作用。使用橡胶手错觉（RHI），我们表明，一个人自己的身体的表征是隐含地用于校准感知外部物体。12名参与者在观看大或小手套的刺激同时刺激自己的手时经历了RHI。然后，他们抓住大小相同但重量不同的圆柱体。RHI与大手套导致气瓶感觉更重。我们认为，一个虚幻的手的大小增加，随后抓住圆柱体感觉相应的小，唤起一个大小重量的错觉。因此，自我表征影响了外知觉。一个人对自己身体的感觉为一般的知觉提供了一个基本的参照。
Bodily illusions offer an experimental method to investigate the origins and functional role of the sense of one's own body Using the rubber hand illusion (RHI) we show that a representation of one's own body is implicitly used to calibrate perception of external objects. Twelve participants experienced the RHI while watching stimulation of a large or small glove simultaneously with stimulation of their own hand. They then grasped cylinders of identical size but varying weight. RHI with the large glove caused the cylinders to feel heavier. We suggest that an illusory increase in hand size made the subsequently grasped cylinder feel correspondingly small, evoking a size-weight illusion. Self-representation thus influenced exteroception. The sense of one's own body provides a fundamental reference for perception in general.
