What kind of illusion is the rubber hand illusion?
perceptual illusion
The rubber hand illusion is a perceptual illusion in which a model hand is experienced as part of one’s own body. In the present study we directly compared the classical illusion, based on visuotactile stimulation, with a rubber hand illusion based on active and passive movements.
What’s up with the rubber hand illusion?
In the RHI, synchronous stroking of a person’s real hand, which is hidden from view, and a (suitably positioned) rubber hand can elicit reports that the rubber hand, in some sense, ‘feels like’ the person’s real hand (Botvinick & Cohen, 1998). When the stroking is asynchronous, such reports are typically weaker.
What is the proprioceptive drift?
Proprioceptive drift is a multimodal measure combining the processing of visual, tactile, and proprioceptive information (Botvinick and Cohen, 1998; Tsakiris and Haggard, 2005).
What is the multisensory conflict that gives rise to the rubber hand illusion?
The Rubber Hand Illusion was first explained as a recalibration of real hand proprioception to the false hand as a consequence of a distortion in the interaction of visual, tactile, and proprioceptual sensation (Botvinick & Cohen, 1998).
Is the rubber hand illusion multimodal?
One particularly compelling multisensory illusion involves the integration of tactile and visual information in the perception of body ownership. In the “rubber hand illusion” (Botvinick & Cohen, 1998), an observer is situated so that one of his hands is not visible.
What causes the rubber hand to become perceived as a part of one’s body in the rubber hand illusion?
This proprioceptive drift is usually thought of as a “three-way interaction between vision, touch, and proprioception” [1], in which synchronous stroking (touch) evokes the proprioceptive feeling of the own hand to be displaced towards the seen (visual) rubber hand.
