Experimental paradigm. (A) Experimental design illustration of Visuomotor (VM) and Visuotactile (VT) stimulations, each divided for the Sync (synchronous coupling/stroking on both index fingers), Incong (synchronous coupling/stroking on the subject’s index finger and the rubber hand’s middle finger), and Async (coupling/stroking on both index fingers with a temporal delay) conditions. Red connecting lines in Visuomotor represent the mechanical connection between the subject’s index finger and the rubber hands index finger in Sync, the middle finger in Incong, or the experimenter’s finger for a delayed movement (Async). (B) Experimental procedure of a single run. In each run a single stimulation type (Visuotactile / Visuomotor) and condition (Sync / Incong / Async) was administered, after which the subject completed the Moving Rubber Hand illusion (MRHI) questionnaire that consists of 12 statements probing Sense of Agency and Body Ownership. The order of runs was randomized between subjects.
