Dynamic changes in a pattern of inter-key press intervals during the initial training on Day1. Degree of similarity between patterns of inter-key press intervals (IPIs) was assessed based on normalized Pearson correlation coefficients calculated for each individual using the Fisher’s z-transformation. Mean normalized Pearson correlation coefficients between the primary IPIs pattern generated during the first training block and the subsequent practice (i.e., training blocks 2–14) for each group (upper plot). Mean normalized Pearson correlation coefficients between the IPIs pattern formed by the end of training (i.e., during the last training block) and the preceding practice (i.e., training blocks 1–13) for each group (lower plot). Bars – standard error of the mean (s.e.m.).
