Research suggests that individuals with posttraumatic stress disorder (PTSD) selectively attend to threat-relevant information. However, little is known about how initial detection of threat influences the processing of subsequently encountered stimuli. To address this issue, we used a rapid serial visual presentation paradigm (RSVP; Raymond, J. E., Shapiro, K. L., & Arnell, K. M. (1992). Temporary suppression of visual processing in an RSVP task: An attentional blink? Journal of Experimental Psychology: Human Perception and Performance, 18, 849-860) to examine temporal allocation of attention to threat-related and neutral stimuli in individuals with PTSD symptoms (PTS), traumatized individuals without PTSD symptoms (TC), and non-anxious controls (NAC). Participants were asked to identify one or two targets in an RSVP stream. Typically processing of the first target decreases accuracy of identifying the second target as a function of the temporal lag between targets. Results revealed that the PTS group was significantly more accurate in detecting a neutral target when it was presented 300 or 500ms after threat-related stimuli compared to when the target followed neutral stimuli. These results suggest that individuals with PTSD may process trauma-relevant information more rapidly and efficiently than benign information.
