Article: Cognitive control and posttraumatic stres...

Recently researchers have theorized that individual differences in cognitive control may elucidate processes involved in disorders characterized by intrusive thoughts and memories. In the present study, 77 undergraduate participants with a self-reported history of trauma exposure were administered assessments of cognitive control (working memory capacity; WMC), posttraumatic stress symptoms, trait anxiety, and depression. posttraumatic stress symptoms from each of the three symptom clusters (re-experiencing, avoidance, and hyperarousal) were predicted from trait anxiety, depression, and WMC performance scores using separate regression models. After controlling for trait anxiety and depression, there was a negative, statistically significant relationship between cognitive control and re-experiencing symptoms but not avoidance or hyperarousal symptoms.
