Stress exposure training is the practicing of important existing skills in a stressful and distracting environment to develop the ability to perform them reliably in spite of the circumstances.[1]
There are a number of occupations where a potentially high-stress, high-risk environment can occur, where failure to act appropriately can lead to injury, death or significant loss. These settings can be found in military engagements, aviation, emergency medicine, mining, underwater diving, parachuting, bomb disposal, police work, and fire fighting. These environments impose a high demand on those who work in them, and there is a high potential for immediate and often catastrophic harm following an error. Emergency or crisis conditions can occur suddenly and without warning.[1]
The effects of stress on the individual are a concern in industry, the military, aviation, sports, and other settings where effective performance under stress is required.[1] In this context, stress is a process by which environmental demands result in a perception that demand exceeds resources. This can have negative physiological, psychological, behavioral, or social effects,[1] by restricting attention and distracting the operator from the primary task.[2] Technical skill is a necessary but not always a sufficient condition for effective performance in a stressful environment. Effective training to reduce the negative effects of stress on performance has become important in the training community. The purpose of stress exposure training is to prepare people to function effectively under high-stress conditions.[1]
The main purpose of training is to develop and retain skills, knowledge, understanding and abilities, and most training is occurs in conditions which facilitate learning. These conditions usually involve an environment which is free of avoidable discomfort, surprises, and other distractions, allowing focused concentration on understanding and mastering the components and combinations of skills. This is generally effective when performance will be under similar circumstances, but when transferred to stressful operational conditions, reliable performance is not guaranteed.[1]
The main purpose of stress training is to prepare the person to perform effectively in a high-stress environment. It increases familiarity with the environment and conditions in which the skills must be performed effectively, and develops the ability and confidence to perform those skills in spite of the distractions and task loading present.[1]
