Figure 4

Hand-paths from representative subjects observed on the first trials during the transfer session were compared between the experimental groups (color) and the control (black) in the left panels for 2.1, 2.2, and 2.3, respectively (A-C, left). Mean errors of the first trial were plotted (mean ± standard error) in the mid panels (A-C, middle), and the learning rates were plotted on the right panels (A-C, right). N.S. indicates not significant (p > 0.05).
