Yerkes-Dodson Law
The Yerkes-Dodson law, discovered by researchers Robert Yerkes (pronounced 'Yerk-EES') and John Dodson, establishes that the ideal level of arousal for performance is not constant but varies based on a task's difficulty and complexity. According to this law, simple or well-learned tasks are performed most effectively when arousal levels are relatively high, whereas complex or difficult tasks require lower levels of arousal to achieve peak performance. The general relationship between arousal and performance often follows an inverted U-shaped curve, where moderate arousal yields optimal results compared to extremes like apathy or high anxiety.
