Dec 1, By Bryan Barrett The structures for controlling arousal are located in the brain and can be demonstrated in the following example. A competitor. May 25, 1 Definition; 2 Arousal and Performance; 3 Factors Affecting Level of Arousal; 4 Related Articles; 5 Further Reading There is also a direct relationship between stress and arousal. Coping with long range flying. Start studying Human Performance and Limitations - Level 2. Learn vocabulary The relationship between arousal and flying performance is: approximately the.

The pattern of performance suggested that at low arousal level, there will be low performance level. As the level of arousal is increased, it will reach an optimum level in which performance will decrease even though arousal level is high. However, optimum level of arousal and performance varies for different task. Complex task will have a lower level of arousal and performance compared to simple task. This is because complex task involves greater demands and greater memory loads, hence it is more vulnerable to breakdowns in the process [Thom 8 ].

At low arousal levels, pilots usually do not expect to perform any difficult task, or having low motivation to perform the task, thus human attentional mechanisms will not be particularly active. The flight crew entered into the flight computer degrees instead of degrees. The plane was NM off course.

Arousal vs. Performance

Fuel exhaustion occurred which leads to the forced landing in the jungle. The navigation mistake went unnoticed for 2hours because the flight crews were reported listening to the World Cup Qualification Match between Brazil vs. This example demonstrates what serious consequences will happens if pilots are at low arousal level resulting low stress during flight. They are in a state of boredom during the cruise phase of the flight, thus they switch their transmission towards the commentary of the world cup soccer match.

With low stress among the pilots, they would feel that things are under-control, thus it resulted in the pilots not following procedures to check their bearings. In the end, this low arousal level of pilots creates low stress thus causing navigation error which resulted in an air accident.

With optimum arousal level, it will create optimum amount of stress for a pilot to achieve its best performance in a particular simple or complex task.

Furthermore, communication with the ATC is unclear and distorted.

The pilot has a high arousal level from: All these arousal factors results in a high level of stress. Instead of being over-aroused, the pilot managed to handle the stress and find the way towards Reading Airport to land the aircraft. Heart rate, blood pressure and breathing rate increase, muscles begin to tighten and blood flow is redirected to large muscle groups. The competitor was overly aroused and not in peak position to perform.

Inverted-U Hypothesis The Inverted-U Hypothesis predicts that as arousal increases from drowsiness to alertness there is a progressive increase in performance efficiency. However, once arousal continues to increase beyond alertness to a state of high excitement, there is a progressive decrease in task performance Williams Inverted-U-Hypothesis suggest that performance arousal has a balanced optimal state.

An example of over arousal, the competitor who consumed two scoops of pre-workout before the event, takes fifteen minutes warming up with the implements and his IPOD so loud he cannot hear himself think. We all know this competitor and seldom do they perform to their optimum level.

Most often this example is seen in competitors lacking confidence in an event. Does the complexity of the movement factor into arousal level?

Broadhurst showed that higher levels of arousal can be tolerated on simpler tasks before performance is decreased Broadhurst Essentially, the complexity of the movement needs to be analyzed to determine how much arousal is optimal.

Which event requires the highest amount of muscle activation, amount of coordinative actions, precision and steadiness required, fine motor skills required, and duration of stimulus? Answer being, the yoke walk. Based off the research, our example of the highly aroused competitor will perform better deadlifting in that arousal state compared to a yoke walk because of the simplicity of the movement.

The take home… Research shows there is an optimal level of arousal for peak performance, described by the inverted-u theory.
