While previous work has also implicated adverse effects of sexual assaultive trauma, fewer individuals in the analytic sample were exposed to sexual assaultive trauma compared to other trauma, potentially limiting the power to detect these complex interactive effects. While PGS typically explain only a small percentage of the variance in a trait (Bogdan et al. 2018), future studies can improve these analyses by increasing sample sizes for all groups. There were no significant effects fluid intelligence PGS or nonsexual assaultive trauma alone; only in the interaction did frontal theta ERO differ for the cued no‐go condition. This suggests that genetic risk for fluid intelligence and exposure to nonsexual assaultive trauma be present together to cause the ERO difference. Future studies should consider trauma type, particularly nonsexual assaultive trauma, when investigating neural function risk. Future research could use these altered frontal theta EROs as potential neural markers to predict outcomes like AUD, PTSD, or cognitive outcomes, like fluid intelligence scores, later in life. Understanding how genetic and environmental influences affect neural function and cognitive function is necessary to identify individuals who may benefit from targeted early intervention to prevent severe consequences of these genetic risks and traumatic exposures.
