A higher order interaction (risk group × condition × region) was found for risk group, suggesting that P3 amplitudes between risk groups varied in specific regions and conditions. Follow-up analysis revealed that HR offspring had significantly lower P3 amplitudes in parietal and occipital regions only during loss condition. Further, Bonferroni corrected multiple pairwise comparisons (see Fig. 4, panels A1–A2) revealed that risk group differences in P3 amplitudes (HR < LR) was significant in older males (in central and parietal regions) as well as in younger females in occipital region during the loss condition (see Fig. 5).
