Figure 3.

Evolution of performance during the sequential finger-tapping task. (A) Mean number of correct taps per trial across the 15 trials for the patient group (squares) and for the control group (circles). Vertical stippled lines indicate the three successive phases of the task. The SE of each group is represented by a gray area around the mean values (dark gray: overlap). (B) Mean number of correct taps for each phase consisting of five trials (P1: first half of the learning phase, P2: second half of the learning phase, P3: recall phase) in patient group (squares) and control group (circles). Horizontal lines represent within-group comparisons between P1/P2/P3. *Significant difference P < 0.05.
