The comparison of brain activity at post-test vs. pre-test in each trial block (
). The p was calculated using Wilcoxon signed-rank test, and the W represent statistics (
). The d represents the Cohen’s effect size. The mean and standard deviation represent the mean difference in the average integrated value of oxygenated hemoglobin (oxy-Hb) per second (post-test minus pre-test) and their standard deviations, respectively, for nine subjects.
