A key question is how intrusions are triggered. One possibility is that PTSD is characterized by a processing advantage for stimuli that resemble those that accompanied the trauma, which would lead to increased detection of such cues in the environment.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291711001048_sec_a002\"><jats:title>Method<\/jats:title><jats:p>We used a blurred picture identification task in a cross-sectional (<jats:italic>n<\/jats:italic>=99) and a prospective study (<jats:italic>n<\/jats:italic>=221) of trauma survivors.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291711001048_sec_a003\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>Participants with acute stress disorder (ASD) or PTSD, but not trauma survivors without these disorders, identified trauma-related pictures, but not general threat pictures, better than neutral pictures.
