FIGURE 6.

Cohen’s d effect size values. The bar plot depicts Cohen’s d values to estimate the magnitude of statistical differences in absolute power when S1 (red bar) and S2 (blue bar) were compared with S_R. X-axis exhibits EEG channels whereas Y-axis is the Cohen’s d value, ranging from 0 to 1. The colored background regions represent the intervals to specify the magnitude of the differences throughout channels and between sessions, such as negligible (yellow), small (green), medium (red), and large (blue).
