Research conducted largely in medical and clinical settings suggests that receiving preparatory information prior to a stressful event can reduce negative responses to stress. Although results within this domain have been promising, little research has examined the efficacy of preparatory information on enhancing performance in a more applied task environment. This study examined the effect of preparatory information on reducing stress reactions and enhancing performance on a realistic decision-making task. Results indicated that those who received preparatory information prior to performing under high-stress conditions reported less anxiety, were more confident in their ability to perform the task, and made fewer performance errors than those who received no preparatory information.
