Learning controls. A: mean (±SE) peak tangential velocity of movements made during the motor task for the matched experimental group (red) and the control group (black). B: PD from a straight trajectory throughout normalized movement distance for blocks 1 and 4. No pairwise comparisons at any point in movement distance were significant (P > 0.4 for all comparisons, paired t-tests). C: uncertainty range at baseline (pre) and following the motor task (post) for the matched experimental group (red) and the control group (black).
