Content: There are limits to the amount of stress that one can ethically induce in an experimental situation, and even with highly arousing materials, research participants are usually not personally threatened by the witnessed event; that is, they are bystanders rather than victims or potential victims, which is likely to influence not only their stress level but also their behavior, degree of attention, and so forth. Some innovative research designs have attempted to overcome this limitation by studying victims/witnesses of real crimes or individuals undergoing stressful medical procedures. In conclusion, it is hard to generalize about the effects of stress on eyewitness memory. The findings are somewhat mixed, and the explanation for stress effects on memory is far from clear, making generalization difficult. More research is necessary to resolve this uncertainty. However, it is clear that, overall, high levels of stress harm eyewitness memory in more ways than they help it. References: Deffenbacher, K. A., Bornstein, B. H., Penrod, S. D., & McGorty, E. K.
