Question:
The Yerkes–Dodson law states that _____________.
The Yerkes–Dodson law states that _____________.
Show Hint
Remember the \textbf{inverted-U}: performance peaks at {moderate} arousal (lower for complex tasks, higher for simple tasks).
Updated On: Aug 30, 2025
- performance is affected by the level of arousal
- frustration leads to aggression
- self-concept helps us organize and remember information
- changes in behaviour are a result of experiences that have happened frequently or recently
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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.
