| Outline of Final Research Achievements |
The rubber hand illusion (RHI) is a phenomenon in which hidden human touches to a hand are perceived as arising from a fake hand. First, we investigated whether an externally-produced stimulus is essential for eliciting the RHI. We found that externally-produced tactile stimulation appears unnecessary for RHI. Second, we tested the possibility that the ownership of the body surface on which a visual stimulus is placed enhances the likelihood of a visual-thermal interaction. Results indicated that the sight of an apparently-thermal object on a rubber hand that is illusorily perceived as one’s own hand affects thermal judgments about the object physically touching this hand. Third, we investigated whether “out of body experience” needs local visual-tactile stimulation, when he looks at a video of his back monitored by camera through head-mounted displays. We reported that a broad air flow to one’s body and a view of an electric fan circulating air can not induce such an illusion.
