AbstractAccording to the Yerkes-Dodson law, performance is an inverted-U function of arousal with a negative relationship between optimal arousal and task difficulty. Both easy (letter cancellation) and difficult (verbal abilities) tasks were completed during the morning by 100 subjects differing in impulsivity; each subject was tested with five different doses of caffeine. Data were subjected to a traditional analysis of variance; in addition, data from individual subjects were analyzed. Group-level results indicated that performance was an interactive function of task, caffeine, and impulsivity (P<0.05): As predicted by the Yerkes-Dodson law, performance on the easy task tended to improve as caffeine dosage increased, but on the difficult task, (less aroused) impulsive subjects improved while (more aroused) nonimpulsive subjects first improved and then deteriorated. Moreover, analyses of the performance of individual subjects strongly supported the inverted-U hypothesis (P<0.001). The hypothesis that easier tasks require higher levels of arousal for optimal performance than more difficult tasks received limited support at the individual level. Thus, despite methodological and probabilistic biases against the inverted-U and task-difficulty hypotheses, both group and individual level analyses yielded results consistent with the Yerkes-Dodson law.

Copyright © 1994 Published by Elsevier Ltd. What does the YerkesThe Yerkes-Dodson law is a model of the relationship between stress and task performance. It proposes that you reach your peak level of performance with an intermediate level of stress, or arousal. Too little or too much arousal results in poorer performance. This is also known as the inverted-U model of arousal.
Which level of arousal gives the most effective performance?Research shows that moderate arousal is generally best; when arousal (stress) is very high or very low, performance tends to suffer.
How does the YerkesThe Yerkes-Dodson Law states that for easy tasks, the higher the level of physiological or mental arousal, the higher the performance. But if the task at hand is difficult, a higher level or arousal will only increase performance until a certain point.
Which of the following is true of the YerkesAccording to the Yerkes-Dodson law, which of the following is true? We feel the horror of a bad injury only after we have seen the injury or seen how others react to it.
