Whose hand is this? Handedness and visual perspective modulate self/other discrimination.

We required healthy subjects to recognize visually presented one's own or others' hands in egocentric or allocentric perspective. Both right- and left-handers were faster in recognizing dominant hands in egocentric perspective and others' non-dominant hand in allocentric perspective. These findings demonstrated that body-specific information contributes to sense of ownership, and that the "peri-dominant-hand space" is the preferred reference frame to distinguish self from not-self body parts.
