According to optimum arousal theory, which level of arousal is typically best for performance?

• A. Low Arousal
• B. Moderate Arousal
• C. High Arousal
• D. No Arousal

Answer: (B)

Moderate arousal tends to produce the best performance because it hits the sweet spot between being too sleepy and too stressed. When arousal is too low, you’re not motivated or focused enough, so attention wanes and performance suffers. When arousal is too high, anxiety and physiological stress can overwhelm thinking and motor control, leading to mistakes and slower responses. The peak effect, known from the optimum arousal idea, sits in the middle, where you’re alert and energized but not overwhelmed. It’s also helpful to note that the exact level can shift with task difficulty: easier, well-practiced tasks can handle a bit more arousal, while harder, novel tasks typically require lower arousal to maintain careful thinking and accuracy.
