Rubber hand illusion and somatosensory attenuation

In a series of experiments that included 48 participants, ages 20-37, researchers quantified the perceived somatosensory intensity of touch applied to the participants’ fingers, and found that a rubber hand touching a participant’s finger produced a similar intensity to an identical touch by the participant’s own finger, if the participant experienced illusory feelings of body ownership toward the rubber hand, suggesting that somatosensory attenuation that usually accompanies self-touch depends on perceived ownership of the hand.
