| Research Abstract |
How do humans make their own hands successfully interact with objects? Previous studies have suggested that the ability to perceive the space around one's own hand is essential for successful interactions with objects. However, it remains unknown how this perceptual ability works. The present study shows an illusion of visual motion that is induced by seeing one's own hand. Importantly, this illusion had spatial selectivity in hand-centered coordinates, and occurred only when participants actively moved the hand that was felt to be their own. These findings reveal that the brain has the special mechanism underlying spatial recognition relative to one's own hand, suggesting that bodily self-consciousness plays a functional role in guiding movements of one's own hand.
