What does the Yerkes-Dodson Law suggest about memory and performance?

1. Memory is best in high states of arousal

2. Performance is optimized at low arousal levels

3. Performance is best when arousal is at a moderate level

4. There is no relationship between arousal and performance

The correct answer is: Performance is best when arousal is at a moderate level

The Yerkes-Dodson Law describes the relationship between arousal and performance, suggesting that there is an optimal level of arousal for performance effectiveness. According to this principle, performance increases with arousal but only up to a certain point; beyond that peak, further increases in arousal can lead to a decline in performance. In the context of memory and performance, the law implies that cognitive tasks, including those involving memory, often require a moderate level of arousal for individuals to function at their best. This means that at a moderate level of arousal, individuals are generally more focused and can retrieve memories or perform tasks more efficiently. Too little arousal can lead to lethargy or lack of motivation, while too much arousal can result in anxiety or distractions that hinder cognitive processes. This balance highlights the importance of managing arousal levels in settings where memory and performance are critical, such as in education or high-stakes testing.
