化身，通过橡胶手错觉（RHI）来衡量，取决于被化身的物体和它所取代的身体部分之间的相似性。我们比较了一只与真手相似的假手和一只大小相同但由金属丝（机械）制成的假手。研究人员测试了左、右两个版本，以调查外观对左手的影响是否更强。我们发现，机械手诱发了体现，尽管相对于真实的手，其程度有所降低（N = 120）。左右两个版本的机械手在错觉的强度上没有区别。然而，对于左手来说，漂移（错觉的客观测量）和对问卷的认同（主观体验）之间存在更强的关系。对于机械手，客观和主观的测量是不相关的。我们讨论了与影响RHI和半球差异的因素有关的结果。(C) 2014爱思唯尔公司版权所有。
Embodiment, as measured through the rubber-hand illusion (RHI), depends on the similarity between object to be embodied and part of the body it replaces. We compared a fake hand similar to a real hand, and one matched in size but made of wires (mechanical). Left and right versions were tested to investigate whether the effect of appearance was stronger in the left hand. We found that the mechanical hand induced embodiment, though to a reduced degree relative to the realistic hand (N = 120). Left and right versions of the mechanical hand did not differ in strength of the illusion. However, with the left realistic hand there was a stronger relationship between drift (an objective measure of the illusion) and agreement on the questionnaire (subjective experience). With the mechanical hand, objective and subjective measures were unrelated. We discuss the results in relation to factors that influence the RHI and hemispheric differences. (C) 2014 Elsevier Inc.
