Performance for Experiment 2. (A) The movement errors of Group2.1 in the learning, decaying, and transfer sessions were plotted in green lines and shaded areas (mean ± standard error). During the decaying session, the cursor feedback was always on the straight line connecting the start and target circles. The black plot represented the control group’s performance in the transfer session. The performance of Group2.2 and 2.3 were depicted in (B) and (C), respectively. During the decaying session, a force channel restricted the hand-paths of Group2.2 along the straight line connecting the start and target circles, so the hand-paths were always straight and accurate. No cursor feedback was provided for Group2.3 during the decaying session, so the subjects reached towards the target based on their proprioception.
