Abstract: Attentional bias towards threat is a common phenomenon in Posttraumatic Stress Disorder (PTSD) individuals. A number of studies have investigated the processing characteristics and internal mechanisms of attentional bias by using eye-movement technology. Results are inconsistent about components of attentional bias, but still provide evidences for different models, such as vigilance-avoidance model and attentional maintenance model. Based on eye-movement patterns from different dimensions, the future studies should pay attention to the model building and integration while recording the eye movements of PTSD individuals. Furthermore, researchers could combine multiple technologies to investigate the threat attention bias mechanism of PTSD individuals from a multimodal perspective.

Key words: Posttraumatic Stress Disorder, attentional bias, eye-movement
