New research could lead to a better understanding of how the brain works in people with autism. Using the 'rubber-hand' illusion, the researchers examined how adults with autism experienced 'ownership' of a fake prosthetic hand. In the 'rubber-hand' illusion, one of the subject's hands is placed out of sight, while a rubber hand sits in front of them. By stroking the fake hand at the same time as the visible real one, the subject can be convinced the fake hand is theirs. The results of this experiment showed differences between those with autism and those without.
