• A. James-Lange Theory
• B. Cannon-Bard Theory
• C. Yerkes-Dodson Law
• D. Schachter-Singer Theory

Answer: (C)

Verified step by step guidance

1. Identify the key concept in the question, which relates to how arousal levels affect performance.
2. Recall that the James-Lange Theory, Cannon-Bard Theory, and Schachter-Singer Theory are all theories of emotion, not specifically about arousal and performance.
3. Understand that the Yerkes-Dodson Law specifically addresses the relationship between arousal and performance, stating that performance improves with arousal up to an optimal point, after which it declines.
4. Recognize that this law suggests a curve where moderate arousal leads to the best performance, while too little or too much arousal can impair performance.
5. Conclude that the correct answer is the Yerkes-Dodson Law because it directly explains the effect of arousal on performance.
