Experiment 1. (a) The experimenter started each condition by brushing the left hand of the subjects and a rubber hand, either synchronously or asynchronously (as control). This was followed by the numbness test where the subjects either watched only the rubber hand being brushed by an experimenter (other condition) or brushed the rubber hand themselves (self condition). (b) The numbness score and the ownership score on seven-point Likert scales plotted together. A 2 × 2 ANOVA revealed that, while the ownership did not change between the self and other conditions, the numbness changed significantly, F1,56 = 4.576, p = 0.037.
