Means and standard deviations of directional errors in the adaptation phase, from subjects pointing with their right (R) or left hand (L) to visual (V) or auditory (A) targets.

<p>Subjects pointing with their right hand were exposed to a +30 deg rotation of feedback and their responses therefore deviated by up to +30 deg from the target direction. Subjects pointing with their left hand were exposed to a −30 deg rotation, and their responses therefore deviated by up to −30 deg from the target direction.
