The Rubber Foot Illusion (RFI) is an illusion in which one is made to feel that a model foot is their own through synchronous visuo-tactile stimulation. Previous research suggests that the conditions the RFI can be elicited under are similar to those of the Rubber Hand Illusion (RHI). However, it was unknown if the RFI could be elicited by synchronous movement of a participant's foot and a model foot. To examine this, we developed the Moving Rubber Foot Illusion (mRFI) and compared participants' experience of it to the RFI. The results of this study suggests that the RFI can be elicited through synchronous movement, and results in more proprioceptive drift than a static variant of the RFI. More work is needed to better understand the mechanisms underlying the mRFI.
橡胶脚错觉(RFI)是一种错觉,通过同步的视触刺激,使人感觉模型脚就是自己的脚。先前的研究表明,RFI 可以被诱发的条件与橡胶手错觉(RHI)相似。然而,尚不清楚 RFI 是否可以通过参与者的脚和模型脚的同步运动来诱发。为了检验这一点,我们开发了移动橡胶脚错觉(mRFI),并将参与者的体验与 RFI 进行了比较。这项研究的结果表明,RFI 可以通过同步运动来诱发,并且比 RFI 的静态变体产生更多的本体感觉漂移。需要更多的工作来更好地理解 mRFI 的机制。
