Yerkes-Dodson’s model

Definition

Yerkes-Dodson’s model is a psychological concept that suggests that performance on tasks is best when arousal levels are moderate. It proposes an inverted-U relationship between arousal and performance, indicating that as arousal increases, so does performance up to a certain point, after which further increases in arousal lead to a decline in performance.
