This scenario best exemplifies the Yerkes-Dodson law, which states that performance is best at moderate levels of arousal. Darrin's best performance occurs when his arousal level is moderate, which happens when his family and friends are nearby. When he is alone, he is not aroused enough, and when he is at recitals with strangers, he is overly aroused, leading to mistakes.
