Protocols and the motor performance for Experiment 1. (A) The experimental protocol consisted of four sessions: baseline (veridical feedback), learning (30° CCW rotation), decaying, and transfer (30° CCW rotation with the opposite arm). The cursor feedback was CCW rotated by 30° from the hand-path in the learning and transfer sessions. (B) Mean time-course of the movement errors of the learning, decaying, and transfer sessions were plotted in red lines across trials for Group1.1. Standard errors were represented as the shaded area plot. Veridical cursor feedback was provided during the decaying session as shown in the mid panel. The control group’s right arm performance in the transfer session was plotted as black line in the right panel for comparison. (C) Mean time-course of the movement errors for Group1.2 in blue lines. The subjects sit idle during the decaying session (mid panel). The control group’s right arm performance was plotted in black in the right panel for comparison.
