Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) tests were conducted to assess the demographic and psychological variables. Then, Bonferroni-corrected post hoc comparisons were performed using pairwise analyses; P-values = 0.025 were considered to indicate statistical significance. Prior to the statistical analyses, all EEG variables were transformed using Fisher’s z-transformation to normalize the data distribution. To allow for possible unknown correlations between outcomes that could have arisen from the multiple comparisons, separate generalized estimating equations (GEEs)73 were conducted to assess the EEG data from each of the following frequency bands: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz), beta (12–25 Hz), and gamma (30–40 Hz).
