Our body has evolved in terrestrial gravity and altered gravitational conditions may affect the sense of body ownership (SBO). By means of the rubber hand illusion (RHI), we investigated the SBO during water immersion and parabolic flights, where unconventional gravity is experienced. Our results show that unconventional gravity conditions remodulate the relative weights of visual, proprioceptive, and vestibular inputs favoring vision, thus inducing an increased RHI susceptibility.
我们的身体是在地球引力环境下进化而来的，而引力条件的改变可能会影响身体自我认知感（SBO）。我们通过橡皮手错觉（RHI）实验，研究了在水浸和抛物线飞行过程中的身体自我认知感，在这些过程中会体验到非常规重力。我们的结果表明，非常规重力条件会重新调整视觉、本体感觉和前庭输入的相对权重，更有利于视觉，从而导致橡皮手错觉易感性增加。
