Abstract

Eye tracking research in posttraumatic stress disorder (PTSD) is only just emerging, with only a handful of studies completed. The majority of studies have focused on identifying attentional biases toward threat which is proposed as one of the maintaining factors underlying anxiety. At this preliminary stage, current findings reveal evidence for an early attentional bias toward trauma-relevant stimuli in PTSD, with less consistent evidence of subsequent avoidance. However, longitudinal studies are emerging which suggest that attentional avoidance of threat may be a risk factor for developing higher PTSD symptoms in military settings. Eye tracking technology provides significant advances over traditional attentional bias paradigms, as it enables the continuous assessment of visual attention, allowing for both valuable convergent spatial and temporal information. This enables the assessment of both initial attention and avoidance of threatening stimuli. In addition, eye tracking technology may be usefully applied in alternative paradigms assessing social cognition (such as visual scanning of facial expressions) to identify further important aspects of emotional and social processing in PTSD.
