Cues used to modify limbs position in body representation when displayed arms are manipulated

Abstract

Training with distorted vision has been shown to change posture information in a body representation. We investigated an interaction in a change of symmetric body parts in the body representation, both upper limbs. Two cues that made clear the positional relationship between both hands were tested to whether these facilitated the representation change: (1) whether the participants move both hands simultaneously, and (2) whether the participants move both hands to the same point. The results of our experiments showed that the representation of both hands was changed with neither cue but not facilitated by either of the cues.
