Which theory is attributed to the pair that described the inverted-U curve?

• A. Inverted U theorist
• B. Drive theory
• C. Hull
• D. Yerkes and Dodson

Answer: (D)

The idea being tested is how arousal levels relate to performance. The inverted-U curve shows that performance improves as arousal rises, up to an optimal point, but if arousal becomes too high, performance drops. This specific attribution is given to Yerkes and Dodson, who described this arousal–performance relationship. Drive theory would predict a more direct, linear rise in performance with increasing arousal, which doesn’t account for the decline after the peak. Hull is associated with drive theories but not with the particular arousal–performance curve named after Yerkes and Dodson. The phrase “inverted-U theorist” isn’t a specific attribution, so the best fit is the duo who published this law together.
