Which statement describes the inverted U model of arousal and performance?

• A. Low arousal leads to poor performance
• B. Moderate arousal yields best performance
• C. High arousal yields the best performance
• D. Arousal has no effect on performance

Answer: (B)

The inverted U model shows that performance improves as arousal rises from low to a moderate level, but then declines as arousal becomes too high. At moderate arousal, attention is focused, motivation is optimized, and bodily readiness supports performance without the distracting tension that comes with excess arousal. That combination tends to produce the best outcomes in skill execution and focus, which is why moderate arousal is the most effective state. Low arousal can lead to drifting attention and under-preparation, while very high arousal can cause anxiety, muscle tension, and impaired precision. Arguing that arousal has no effect ignores the clear link between arousal levels and performance, and claiming that high arousal yields the best performance conflicts with the model’s peak at moderate levels.
