Fear-Potentiated Startle: A Review from an Aviation Perspective

Pilot performance following unexpected critical events has been either ineffective or inappropriate in some recent aircraft accidents. The deleterious effects of startle have been identified as causal or contributory in these events. The startle reflex, fight or flight reaction, and stress response are discussed. Threat has the effect of potentiating startle effects and has significant deleterious effects on cognition. This could contribute to poor performance following an unexpected critical event in aviation. Training strategies for improved performance, which would expose pilots to unexpected critical events more often, and develop greater self-efficacy, are discussed.
