Which statement best captures the core idea of the inverted U shaped relationship between stress and performance?

• A. The Inverted U-Shaped Relationship Between Stress And Performance
• B. Stress Has No Effect On Performance
• C. Performance Improves Indefinitely With More Stress
• D. Optimal Performance Occurs At Zero Stress

Answer: (A)

Performance under pressure follows an inverted U: as stress rises from low to moderate, performance tends to improve, but when stress becomes too high, performance declines. The statement that best captures this is that there is an inverted U-shaped relationship between stress and performance. This reflects an optimal level of arousal where you’re alert and focused, while too little stress leads to under-arousal and dullness, and too much stress causes anxiety and cognitive overload that impair functioning. Other ideas—stress having no effect, performance improving indefinitely with more stress, or optimal performance at zero stress—don’t fit because they ignore how performance actually rises then falls as arousal changes.
