The rubber hand illusion (RHI) is a perceptual illusion in which participants perceive a model hand as part of their own body. Here, through the use of one questionnaire experiment and two proprioceptive drift experiments, we investigated the effect of distance (12, 27.5, and 43cm) in the vertical plane on both the moving and classical RHI. In both versions of the illusion, we found an effect of distance on ownership of the rubber hand for both measures tested. Our results further suggested that the moving RHI might follow a narrower spatial rule. Finally, whereas ownership of the moving rubber hand was affected by distance, this was not the case for agency, which was present at all distances tested. In sum, the present results generalize the spatial distance rule in terms of ownership to the vertical plane of space and demonstrate that also the moving RHI obeys this rule.
橡胶手错觉（RHI）是一种知觉错觉，在这种错觉中，参与者会将一只模型手视为自己身体的一部分。在此，通过一项问卷调查实验和两项本体感觉漂移实验，我们研究了垂直平面上距离（12厘米、27.5厘米和43厘米）对动态和经典橡胶手错觉的影响。在这两种错觉版本中，我们发现距离对所测试的两种测量方式下橡胶手的归属都有影响。我们的结果进一步表明，动态橡胶手错觉可能遵循更窄的空间规则。最后，虽然动态橡胶手的归属受距离影响，但代理感并非如此，在所有测试距离下都存在代理感。总之，目前的结果将关于归属的空间距离规则推广到了空间的垂直平面，并证明动态橡胶手错觉也遵循这一规则。
