Memory fails you after severe stress

s sequentially.

Using a scale of 1 to 10, participants were asked to say how confident they were that they had chosen the right person. Most of the mock interrogators appeared or were pictured dressed in standard military garb, but some were shown dressed exactly as they had been during the questioning.

The performance of all groups was abysmal. Only 30 per cent could find the right person in a line-up, 34 per cent from a photo-spread and 49 per cent from sequential photos- though the clothing cue boosted correct identification to 66 per cent (International Journal of Law and Psychiatry, vol 27, p 265). Thirty people got the gender wrong, and those subjected to physical threats were the worst at recognising their interrogator.

Elizabeth Loftus, a psychologist at the University of California at Irvine, says the study is unique because the stresses were intense and real. "I think people will pay attention to this," she adds. Wells agrees: "What it illustrates is that stress does not help memory."
