a-d. Visual stimulation. Display of an artificial mannequin’s body from the first-person perspective and the experimenter applying tactile stimulation to one (a), two (b), or three (c) body parts simultaneously. Visual stimulation was identical for both the synchronous and asynchronous conditions, the difference being the timing of the strokes applied to the participant’s real body. The participant lay on a bed with their head tilted forward and observed these videos through a head-mounted displays (HMD). Panel d displays the final scene comprising the knife in the SCR and illusion onset data collection (which was included for only the 1S, 3S, and 3A conditions; a still image of the mannequin’s body was instead presented at the end of the 1A, 2A and 2S conditions). Note. The presented images appear askew because they are monocular for illustrative purposes; a 3D binocular view (not askew) is achieved only within the HMD.
