Rubber Hand Illusion Experiment

In 2008 it was shown the temperature of the hidden hand actually drops during the illusion source.

Experiments with a fake body part have revealed how the brain becomes confused during a party trick known as the rubber hand illusion. Understanding the neural underpinnings of the rubber hand illusion can also help to treat disorders where body ownership is distorted as is the case in schizophrenia. It can be induced experimentally by manipulating the visual perspective of the subject and also supplying visual and sensory signals which correlate to the subject s body. In 1998 researchers matthew botvinick and jonathan cohen of the university of pittsburgh pa detailed an experiment that people would later refer to as the rubber hand illusion rhi.

A change of perceived finger location towards the rubber hand proprioceptive drift has been reported to correlate with this illusion. Once the illusion had taken hold the researchers smeared fake feces on the rubber hand while simultaneously dabbing the subjects real hand hidden from view with a damp paper towel. To experience the rubber hand illusion you ll need a fake hand of some kind an inflated rubber glove will often do the trick a flat piece of cardboard and two. A rubber hand experiment conducted at vanderbilt lab in 2011 produced an observable repeatable out of body experience source.

In these patients the illusion is stronger with faster induction and increased perceptual reports even during sensory asynchrony. To measure the time course of proprioceptive drift during the rubber hand.
