Which statement about arousal is true?

Which statement about arousal is true?

• A. Arousal is the intensity of motivation and there is an optimum level; under-arousal and over-arousal degrade performance; fight or flight
• B. Arousal is unrelated to performance
• C. Arousal only improves performance
• D. Arousal is the same as fatigue

Answer: (A)

Arousal is the level of mental and physical activation in the body, produced by the autonomic nervous system. As arousal rises from a low level, performance tends to improve because alertness, attention, and readiness to act increase, but there is an optimum level where performance is best. If arousal becomes too high, performance declines because nerves, muscle tension, and distraction interfere with accuracy and control. The fight-or-flight response is a classic example of arousal in action, with heart rate and respiration increasing to prepare for action. This is why the statement is the best: it acknowledges that arousal has an optimal level for performance and explains that both under-arousal and over-arousal can degrade performance, with the fight-or-flight response illustrating arousal in practice. Arousal is not unrelated to performance, it does not always improve performance, and it is not fatigue.
