Behavioral results. A: experimental design showing the average perpendicular deviation (PD) of reaches for each group across trials in the null field on day 1 and in the right FF on day 2. Behavioral data from the learning and control groups are shown in magenta and orange, respectively. Data are shown as 10-trial blocks except for the first 2 blocks in the right FF, which are shown as 5-trial blocks. Error bars represent SE. B: motor learning by observing scores for the learning group and the control group, reflecting initial PD in the right FF relative to baseline PD in the null field. Error bars represent SE. *P < 0.01.
