The rubber hand illusion is a form of so-called body transfer illusion, in which a participant experiences a perceived ownership of a body part other than one’s own. The rubber hand illusion can be induced experimentally by manipulating the visual perspective of the participant, and also supplying visual and sensory signals which are synchronous with signals from the participant’s own body (the sight of brushing of a rubber hand at the same time as brushing the person’s own hidden hand). For the illusion to occur, bottom-up perceptual mechanisms, such as the input of visual information, must override the top-down knowledge that the specific body or body part does not belong to the participant.
