The corrected data were segmented into non-overlapping 2.048 s epochs, and fast-Fourier transforms were conducted using a Hanning window with 10% taper length. Each participant’s data were averaged across the epochs for each electrode, and the mean absolute power was computed for each of the following frequency bands: Delta (0.5–4 Hz), Theta (4–8 Hz), Alpha1 (8–10 Hz), Alpha2 (10–12 Hz), Beta1 (12–20 Hz), Beta2 (20–30 Hz), and Gamma (30–50 Hz). A natural log transform was computed for all EEG power variables and individual electrodes were aggregated to create an average for the following regions: frontal (F7, F3, Fz, F4, F8), central (C3, Cz, C4), parietal (P7, P3, Pz, P4, P8), and temporal (FT7, T7, FT8, T8).
