Fig. 6 — Changes in the means of the psychometric curves across the different congruence conditions. a The tips with which the robots touched the real and rubber hands were made from plastic or foam. Six different combinations of materials touching the real and rubber hands were tested in a 2 × 3 factorial design with three levels of congruence: the congruence condition (all hands touched with the same material), the left incongruence condition (the left rubber hand [lRH] was touched with a different material), and the right incongruence condition (the right rubber hand [rRH] was touched with a different material). Data were collected for one representative participant (S14) in the left incongruence condition (turquoise curve), the congruence condition (blue curve), and the right incongruence condition (indigo curve) when the tip touching the real hand was plastic (upper curves) or foam (lower curves). The changes in the PSE—that is, the rightward or leftward shifts in the mean of the curves, reflect a bias in body ownership towards the rubber hand that is touched by the same material as the participant’s real hand. b Individual (gray bars) and mean (+SD, colored bars) extracted PSEs in the congruence condition (blue plot in the middle), the left incongruence condition (turquoise plot on the left), and the right incongruence condition (indigo plot on the right). A reduced PSE means a bias in body ownership in favor of the rRH, while an increased PSE means a bias towards the lRH. The observed pattern of shifts in PSE indicates that introducing tactile incongruence in stimulation of one rubber hand shifted ownership towards the other rubber hand, as we had predicted. *p < .05. **p < .01. ***p < .001.
