Fig 3 illustrates all possible pairwise comparisons (Bonferroni adjusted) between HR and LR groups. It is clearly shown that the HR group has manifested significantly lower theta power than the LR group in both males and females, while the differences were more robust in males, especially in younger males [panel sets A1 and A2]. Specific differences were observed in: (i) younger males during both loss and gain conditions in all scalp regions (p < 0.001); (ii) older males during the loss condition at central, parietal, and occipital regions (p < 0.001); (iii) younger females during the loss condition only at occipital regions (p < 0.05); and (iv) older females during loss and gain conditions at central and parietal regions (p < 0.05).
