在橡胶手错觉（RHI）中，人们将人造物体归因于自己的身体。在目前的研究中，我们调查了人工物体和人手之间的视觉差异对RHI的影响程度。我们测试了Armel和Ramachandran（2003）的假设，即当人造物体是类似皮肤的纹理薄片而不是桌面时，人们会体验到更强的RHI。我们没有找到支持他们假设的证据，但是当手形物体的纹理不像人类皮肤时（通过在美容假体上戴上白手套来操纵），RHI的强度会减弱。我们为这一发现提供了另一种解释，基于感知身体所有权的基于技能的感觉运动账户。这样的解释支持了Armel和Ramachandran更普遍的观点，即预期触摸和感觉触摸的本质差异会降低RHI。(C) 2008 Elsevier Ltd版权所有。
In the rubber-hand illusion (RHI), people attribute an artificial object to their own body. In the present study, we investigate the extent to which RHI is affected by visual discrepancies between the artificial object and a human hand. We tested Armel and Ramachandran's (2003) hypothesis that people will experience a stronger RHI when the artificial object is a skin-like textured sheet instead of a tabletop. We did not find support for their hypothesis, but the strength of the RHI diminished when the texture of a hand-shaped object did not resemble the human skin (manipulated by putting a white glove over the cosmetic prosthesis). We provide an alternative explanation for this finding, based on a skill-based sensorimotor account of perceived body ownership. Such an explanation supports Armel and Ramachandran's more general claim that discrepancies in the nature of expected and felt touch diminish the RHI. (C) 2008 Elsevier Ltd. All rights reserved.
