Participants trained aiming movements of the right hand to several targets with a prism-like virtual displacement of the location of one of the targets, receiving either terminal or continuous visual feedback. After training, the same targets were to be reached with the untrained left hand under manipulated feedback conditions. The right hand movements continuously adapted to the unnoticed visual displacement, significantly less with continuous than with terminal feedback. Under terminal but not under continuous feedback the adaptation to the manipulated target generalized to targets in the same horizontal direction but not to targets in the opposite direction. Finally, the movements of the untrained left hand showed the same qualitative changes to the targets as the movements of the trained right hand. The data are in line with the notion that the adaptation of the right hand movements is mainly based on a re-interpretation of target locations on which movement control of both hands draws.
