What does the Inverted U Theory describe?

• A. The Inverted U Relationship: Performance Increases With Stress To A Point, Then Declines
• B. Stress Has No Effect On Performance
• C. Performance Increases Linearly With Stress
• D. Higher Stress Always Enhances Performance

Answer: (A)

The Inverted U Theory describes how performance depends on arousal: as stress or arousal rises from low to a moderate level, performance improves, but after reaching that peak, further increases in arousal cause performance to decline. This creates an inverted U-shaped relationship when you plot performance against arousal. The statement that performance increases with stress to a point and then declines captures this idea exactly. It’s not that stress has no effect, nor that performance just keeps improving with more stress, nor that higher stress always helps—each of those overlooks that there’s an optimal level of arousal beyond which performance drops. In practice, tasks vary: simpler tasks can tolerate higher arousal, while complex tasks benefit from lower arousal.
