To date, however, the precise nature of these impairments and the posttraumatic stress disorder symptoms associated with them have not been well understood.MethodsUsing a well-characterized sample of returning United States military OEF/OIF/OND Veterans who varied in posttraumatic stress disorder symptoms, we employed a validated sustained attention paradigm designed to probe fluctuations across two attentional states characterized by prior research, including a peak state termed “in the zone” and a less efficient, more error-prone state termed “out of the zone.” Rewarded and nonrewarded conditions were employed to examine whether motivating strong task performance could ameliorate sustained attention deficits. Analyses examined associations between attentional state, availability of reward, and posttraumatic stress disorde...
