Which principle describes how performance changes with arousal, increasing up to a point and then decreasing?

Which principle describes how performance changes with arousal, increasing up to a point and then decreasing?

• A. The inverted U relationship between arousal and performance
• B. Linear increase of performance with arousal
• C. No relationship between arousal and performance
• D. Decrease in performance with increased arousal

Answer: (A)

Performance rises with arousal up to a moderate level, then falls when arousal becomes too high. This creates an inverted U shape: at low arousal, focus and energy are too low to maximize performance; as arousal increases, concentration and readiness improve, leading to better performance; beyond a certain tipping point, excessive arousal causes anxiety, distraction, and physiological stress that impair accuracy and speed. This pattern explains why you can perform best when you’re alert but not overwhelmed. The other patterns—continuous improvement with more arousal, no relationship, or a constant decline—don’t match the observed peak-and-fall effect described here.
