Fig. 1.

Experimental setup as seen from the experimenter’s view. The rubber hand (a) is presented in a framework occluding the participant’s own hand (b). The participant’s left hand (c) was used on some trials to make a perceptual matching response, mimicking the perceived grip aperture of the right hand. Note that only the rubber hand was visible to the participant, through a layer of Plexiglas (dashed arrow). A cylinder which was also visible to the participant formed the reaching target (d), although actual grasping movements were made without visual feedback
