Movements during random direction of perturbation.

Mean Cursor angle during short block of consistent direction of perturbation (A) and random direction of perturbation (B). Mean Cursor angle is presented as a function of trials. Cursor angle for the ERR group is shown in blue, for the EPE group in violet and for the RWD group in green. Error bars show standard error of mean. (C) Cursor trajectories of a subject from the ERR group. Light blue denotes trajectories with perturbation in the left direction and dark blue denotes trajectories with perturbation in the right direction. (D) Cursor trajectories of a subject from the EPE group. Light violet denotes trajectories with perturbation in the left direction and dark violet denotes trajectories with perturbation in the right direction. (E) Cursor trajectories of a subject from RWD group. Light green denotes trajectories with perturbation in the left direction and dark green denotes trajectories with perturbation in the right direction.
