Experimental apparatus as seen from the experimenter’s viewpoint. The participants sat with their right hand either behind the paper screen (as shown) or in the same position as the rubber hand. The participants’ left hand was positioned inside the mirror box, shielded from view by the opaque cloth and mirror. The wooden block is shown next to the rubber hand for illustrative purposes only, and was moved into the position of the rubber hand during testing. The LED was used for Experiment 5 only, serving as a fixation point and a visual target. In Experiments 1–4, participants fixated the index finger of the rubber hand, their real hand, or the far left lower corner (from their perspective) of the wooden block.
