Abstract
Abstract. The effect of mood on performance in everyday situations is widely studied and the results commonly reveal a mood-congruence relationship. However, little is known about the effect of mood on performance in nonnormal situations such as those experienced during an unscheduled event. This study investigated whether induced mood (positive or negative) influenced performance during an unscheduled aircraft evacuation. Forty-five participants (15 female), with an average age of 21.90 (SD = 3.96) years, were randomly exposed to either positive or negative mood facilitation. Following this, all participants watched the same preflight safety video, and then had to conduct an unscheduled evacuation following a simulated water ditching. Participants exposed to a positive mood manipulator were found to commit fewer errors during the evacuation exercise and completed the evacuation in less than half of the time taken by participants who were exposed to a negative mood manipulator. In safety-critical environments such as aviation, these results highlight the advantages of creating an atmosphere or environment that induces positive moods.
