In one study, soldiers underwent survival training (during which they were deprived of food and sleep) and then a realistic prisoner-of-war interrogation. Although they were face to face with the interrogator for 40 minutes, many soldiers were unable to pick the interrogator out of a lineup the next day. Why?

A. People tend to remember broad outlines, not details, of very stressful events.
B. The stress impaired their memory for the entire experience.
C. Stress prevents amygdala activation.
D. The interrogation was not self-relevant, so the soldiers didn't remember it well.
