Question

The Yerkes–Dodson law states that _____________.

• A. performance is affected by the level of arousal
• B. frustration leads to aggression
• C. self-concept helps us organize and remember information
• D. changes in behaviour are a result of experiences that have happened frequently or recently

Hint:

Remember the \textbf{inverted-U}: performance peaks at {moderate} arousal (lower for complex tasks, higher for simple tasks).

Answer 1

The Correct Option is A

Step 1: Statement of the law.
The Yerkes–Dodson law proposes an inverted-U relation between {arousal} and {performance}: too little arousal $\Rightarrow$ low alertness; moderate arousal $\Rightarrow$ optimal performance; too much arousal $\Rightarrow$ performance declines.

Step 2: Eliminate distractors.
(B) is the frustration–aggression hypothesis, not Y–D.
(C) concerns self-schema/memory, not arousal.
(D) is the law of recency/frequency in learning, not Y–D.
Hence, \fbox{(A)} is correct.
