The Yerkes–Dodson law is defined this way (Wikipedia):
The Yerkes–Dodson law is an empirical relationship between pressure and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908.1 The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.
But also according to Wikipedia, there are alternative models of the Yerkes–Dodson law.
Other theories and models of arousal do not affirm the Hebb or Yerkes-Dodson curve. The widely supported theory of optimal Flow presents a less simplistic understanding of arousal and skill-level match. Reversal theory actively opposes the Yerkes-Dodson law by demonstrating how the psyche operates on the principle bistability rather than homeostasis.
I wonder if the "reversal theory", which seems to mainly come from one researcher, really successfully contradicts the Yerkes–Dodson law.
