State
The Yerkes-Dodson law states that performance is best at moderate arousal, and that the optimum is lower for difficult tasks.
Show
Mild nerves improve a familiar presentation and the same arousal degrades a first attempt at a complex task.
Watch for
Task difficulty moves the peak. There is no single arousal level that is best in general.
