The Yerkes-Dodson law states that performance is best at an intermediate level of arousal, with both low and high levels leading to decreased performance. This explains Darrin's best performances occurring when his arousal level is moderate with family and friends nearby, and why he makes mistakes when his arousal is either too high or too low.
