This comprehensive review aims to survey current literature on information processing biases in posttraumatic stress disorder (PTSD). In line with current work in the field, the review will be organized by information processing systems including attention, judgment and interpretation, and memory. Studies outlined suggest that these cognitive processes may be key factors involved in the development and maintenance of PTSD. However, inconsistencies exist in the literature within each domain, often depending on assessment format employed. Studies on attention bias demonstrate both facilitated engagement toward and difficulty disengaging from threatening stimuli. Literature on judgment and interpretation biases indicates that those with PTSD are more likely to interpret ambiguous situations as threatening, in addition to over-estimating subjective risk. Memory studies reveal mixed findings; a number of studies found that those with PTSD exhibit a bias toward remembering threat-relevant or negative stimuli compared to those without PTSD, while others could not replicate this effect. Existing evidence for information processing biases in each of these domains will be integrated and future directions for empirical study outlined.
