This study investigated interaction effects between cognitive function PGS and types of trauma exposure on CPT performance and frontal theta EROs. A significant interaction effect between the fluid intelligence PGS and nonsexual assaultive trauma was observed. Individuals with lower fluid intelligence PGS and a nonsexual assaultive trauma had lower frontal theta ERO power during the no‐go condition of the CPT compared to individuals with higher fluid intelligence PGS. These results suggest nonsexual assaultive trauma may moderate associations between polygenic factors and neural function.
