Delta band power was significantly different among the binge and between the sex groups. Post-hoc assessment revealed that the high-binge group exhibited greater spectral mean power compared to the low-binge group (p = 0.008), with high-binge drinkers having greater power than low-binge drinkers across electrodes (32.6 vs. 31.6 μV2). No reliable effects for the non-binge relative to binge groups were obtained (p > 0.10 in all cases). Separate post-hoc analyses produced the same statistical pattern for each sex group. It is noteworthy that (the non-significant) greater delta power for females compared to males appear to have contributed to the outcome patterns by increasing the group differences for the high-binge subjects more for the females than the males. These differences may reflect the different alcohol consumption levels used to define binge drinking for each sex [2].
