Abstract

Previous research has shown that central nervous system recognize own body through integration of visual and somatosensory information regarding the body. However, no study has examined the contribution of hearing in recognizing own body so far. The present study shows that auditory cues are effective when we recognize our body. In our experiment, participants tapped surface of the floor while hearing the tapping sound presented from double distance of the actual tapped position. After adaptation to this auditory-somatosensory conflict, the length of the arm which tapped the floor was perceived longer than that before the adaptation. The results suggest that unconscious representation of body is updated through adaptation to the auditory-somatosensory conflict.
