Fundamental questions regarding the nature and function of attentional bias (AB) to threat in the etiology of posttraumatic stress disorder (PTSD) remain unanswered. We tested the temporal interplay between trauma exposure, dysregulated attentional processing of threatening information pre- and post-trauma, and the development of posttraumatic intrusions. ⋯ We conclude that one mechanism through which trauma exposure may contribute to the development of PTSD is through its dysregulation of attentional processing of trauma event-related cues. Future work may focus on delineating the developmental course through which attentional dysregulation post-trauma and posttraumatic intrusions unfold and interact.
