Degree of similarity between patterns of inter-key press intervals. 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. (A) Mean normalized Pearson correlation coefficients of IPIs pattern formed by the end of the initial training (i.e., during the last training block on Day1) with IPIs pattern for the reactivation block on Day2 (React) and for the first retest-block on Day3 (Retest) for ReactInt, React8hInt and ReactNoInt group (upper plot). Mean normalized Pearson correlation coefficients between IPIs patterns formed by the end of the initial training on Day1 and each retest-block on Day3 (1–7) for each group (lower plot). (B) Mean normalized Pearson correlation coefficients between IPIs patterns for the first retest-block and during the subsequent repeated practice (i.e., retest-blocks 2–7) for each group. Bars – standard error of the mean (s.e.m.). *Significant results at .05 level, #Significant results at .01 level.
