According to the ________, people perform best when mental and physical arousals are moderate rather than extreme.

A) Peter principle
B) Yerkes-Dodson law
C) peak-end rule
D) Pygmalion effect

The Yerkes-Dodson law states that people perform best when mental and physical arousal are moderate rather than extreme. This means that if arousal levels are too low, performance will be poor because the individual lacks motivation and focus. Conversely, if arousal levels are too high, performance will also suffer because the individual becomes too stressed or anxious to focus effectively. Therefore, moderate arousal levels are optimal for peak performance.
