I have previously posted about the original 'rubber hand illusion' in which participants are convinced a fake rubber hand is their own. A classic low tech experiment that can help us "understand how sight, touch and “proprioception” the sense of body position, combine to create a convincing feeling of body ownership, one of the foundations of self-consciousness (Nature 1998, vol 391, p 756 )” Further to this research recent studies have gone on to experimentally induct of out of body experiences or create body swap illusions. [ Henrik Ehrsson and Olaf Blanke http://www.eurekalert.org/pub_releases/2007-08/ucl-foe081407.php ] Between these two experiments, several interesting versions of hand-related experiments also exist which demonstrate the plasticity of our body perception... The Alien Hand Experiment first created in the 1960s predates the Rubber hand experiment, seems more 'trick'
