Attention bias has been proposed to contribute to symptom maintenance in Posttraumatic Stress Disorder (PTSD), although the neural correlates of these processes have not been well defined. When engaging in tasks that require attention, individuals with PTSD have demonstrated altered activity in brain regions such as the dorsolateral prefrontal cortex (dlPFC), anterior cingulate cortex (ACC), ventrolateral prefrontal cortex (vlPFC), and amygdala; however, few PTSD neuroimaging studies have employed tasks that both measure attentional strategies being engaged and included emotionally-salient information, which was the goal of the present study. We administered a modified attention bias task, the dot probe, which is …
