在著名的橡胶手错觉（RHI）中，观看橡胶手被抚摸，同时自己看不见的手也被同步抚摸，会导致自己的手的感知位置向橡胶手重新定位[Botvinick，M.，＆Cohen，J。 （1998）。橡胶手“感觉”到眼睛看到的触感。自然，391（6669），756]。由于失去了手的真实位置，因此无法正确引导手的动作。准确表示身体部位的位置确实是任何正确运动命令的必要先决条件 [Graziano, M. S. A., & Botvinick, M. M. (1999)。大脑如何代表身体：神经生理学和心理学的见解。见 D. Gopher, & A. Koriat (Eds.)，注意力和表现 XVII-理论与应用的表现交互的认知调节（第 136-157 页）]。然而，尚未研究动作是否确实受到朝向橡胶手的本体感觉漂移的影响，也尚未评估 RHI 中视觉捕捉对新本体感觉信息的抵抗力。在目前的两个运动学实验中，我们首次证明了动作抵抗 RHI，并且 RHI 抵抗动作。换句话说，我们展示了对错觉不敏感的弹道运动反应与对错觉敏感的感知身体判断之间的分离。此外，即使在主动运动之后，受刺激的手的感知反应也被认为更接近橡胶手。这挑战了这样一种观点，即任何通过受刺激的手的主动运动进行的本体感觉更新都会消除这种错觉。这些结果扩展了关于健康大脑中身体表征的知识，并且与目前主要基于神经心理学患者的两种类型身体表征之间最常用的分离一致[Paillard, J. (1991)。知道在哪里并知道如何到达那里。见 J. Paillard（主编），《大脑与空间》（第 461-481 页）；佩拉德，J.（1999）。身体图式和身体意象：入耳聋患者的双重分离。见 G. N. Gantchev、S. Mori 和 J.Massion（编辑），电机控制，今天和明天（第 197-214 页）]。 (C) 2008 Elsevier Ltd. 保留所有权利。
In the well-known rubber hand illusion (RHI), watching a rubber hand being stroked while one's own unseen hand is synchronously stroked, induces a relocation of the sensed position of one's own hand towards the rubber hand [Botvinick, M., & Cohen,J. (1998). Rubber hands 'feel' touch that eyes see. Nature, 391(6669), 756]. As one has lost the veridical location of one's hand, one should not be able to correctly guide one's hand movements. An accurate representation of the location of body parts is indeed a necessary pre-requisite for any correct motor command [Graziano, M. S. A., & Botvinick, M. M. (1999). How the brain represents the body: Insights from neurophysiology and psychology. In D. Gopher, & A. Koriat (Eds.), Attention and performance XVII-Cognitive regulation of performance interaction of theory and application (pp. 136-157)]. However, it has not yet been investigated whether action is indeed affected by the proprioceptive drift towards the rubber hand, nor has the resistance of visual capture in the RHI to new proprioceptive information been assessed. In the present two kinematic experiments, we show for the first time that action resists the RHI and that the RHI resists action. In other words, we show a dissociation between illusion-insensitive ballistic motor responses and illusion-sensitive perceptual bodily judgments. Moreover, the stimulated hand was judged closer to the rubber hand for the perceptual responses, even after active movements. This challenges the view that any proprioceptive update through active movement of the stimulated hand erases the illusion. These results expand the knowledge about representations of the body in the healthy brain, and are in line with the currently most used dissociation between two types of body representations so far mainly based on neuropsychological patients [Paillard, J. (1991). Knowing where and knowing how to get there. In J. Paillard (Ed.), Brain and space (pp. 461-481); Paillard, J. (1999).
