This table depicts the task-dependent differences illustrated in Figure 10 as a function of the constituent frequency bands. For each subject, trial epoch, and frequency band, a Kruskal–Wallis test was used to compare differences in dynamic variability between correct WM, incorrect WM, and control task trials. For each comparison, an H statistic and a p value are noted. Entries in red font correspond to statistically significant conditions in which correct WM trials show the greatest dynamic variability and control task trials the least. Asterisks denote significant deviations from that order of differentiation of variability.
