To our knowledge, no study has examined how trauma moderates the relationship between PGS of cognitive function on neural response inhibition. The most significant finding involved interaction effects between the fluid intelligence PGS and nonsexual assaultive trauma on frontal theta ERO power during the cued no‐go condition of the CPT. Fluid intelligence is a higher‐level cognitive skill that represents the ability to reason in novel situations (Aydmune et al. 2020). Inhibition is an executive function associated with the prefrontal cortex, involving cognitive processes related to control of emotions, thoughts, and conduct during goal‐directed behavior (Aydmune et al. 2020), and has been shown to play a role in fluid intelligence (Aydmune et al. 2020; Diamond 2013; Michel and Anderson 2009). Nonsexual assaultive trauma exposure negatively affects inhibition development, leading to adverse consequences such as substance problems and aggressive behavior (Bounoua et al. 2020). While inhibition contributes to fluid intelligence development and trauma exposure can negatively affect inhibition, and the literature suggests a genetic component to cognitive function, no study has investigated how trauma influences the relationship between genetic risk for cognitive impairment and cognitive processing later in life.
