Movements during consistent direction of perturbation.

(A) Mean values of Cursor path area and Cursor angle combined for both directions of perturbation showing the progression of learning. Cursor path area and Cursor angle for the ERR group are shown in blue, for the EPE group in violet and for the RWD group in green. Error bars show standard error of the mean. Shaded areas represent trials without perturbation and non-shaded areas represent trials with perturbation. (B) Example trajectories of catch and de-adaptation trials. Because there is no perturbation for these trials, cursor trajectories correspond to the hand movement trajectories. Trajectories from the ERR group are shown in blue, for the EPE group in violet and for the RWD group in green. (C) Comparison of aftereffects between the ERR, EPE and RWD groups. Average Cursor path area and Cursor angle for baseline, catch and de-adaptation trials. Error bars show standard deviation.
