A: experimental setup. Target was displayed on 1 of 2 target locations, one for left and the other for right arm. B: experiment 1. In continuous visual feedback condition, a cursor representing fingertip location was shown throughout movement. In binary error (BE) feedback condition, no cursor was shown; instead, target color changed to red (success) or blue (failure) upon completion of reaching movement. C: experiment 2. One group of subjects reached toward 0-degree target (where target visually appeared), and another group toward 30-degree clockwise target (where they would reach toward following complete visuomotor adaptation) with right arm during left-arm training session.
