The Yerkes—Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in When levels of arousal become too high, performance decreases. The process is often illustrated graphically as a bell-shaped curve which increases and then decreases with higher levels of arousal. Research has found that different tasks require different levels of arousal for optimal performance.
A certain amount of arousal can be a motivator toward change with change in this discussion being learning. It was clear from the experiment that arousal levels helped to focus Yerkes dodson law of arousal and motivation on the task at hand, but only until an optimum point.

Coon, D. In psychology, this relationship between arousal levels and performance Pornstar melody foxxe known as the Yerkes-Dodson Law. The inverted U-curve model shown above is only for illustration, Yerkes dodson law of arousal reality however is slightly different from individual to individual depending on the situation. The downward part is caused by negative effects of arousal or stress on cognitive processes like attention e. Research shows that moderate arousal is generally best; when arousal stress is very high or very low, performance tends to suffer. Belmont, CA: Thomson Wadsworth. Brain and Cognition. Bryan College is a regionally accredited, liberal arts institution that offers over 50 different programs, ranging from Associates' to Masters' degrees. Psychologists Robert M. Article Sources. When excitation levels become too high, performance decreases. Our ability to focus on everything happening in our surrounding diminishes as our tension levels rise up, causing the performance to lower. When a player is poised to make an important move, like making a basket during a basketball game, an ideal level of arousal can sharpen his performance Yerkes dodson law of arousal enable him to make the shot. Increased arousal can help improve performance, but only up to a certain point.
Theories of learning assert that there is an optimal level of arousal stress that we all try to maintain.
- In , psychologists Robert Yerkes and John Dillingham Dodson described an experiment in which they were able to motivate rats through a maze using mild electrical shocks.
- Psychologists Robert M.
- Yerkes-Dodson law suggests that elevated arousal levels can improve performance up to a certain point.
The Yerkes — Dodson Law suggests that performance and arousal are directly related. In simpler terms, increase in arousal to a certain level can help to boost performance. Once the arousal crosses the optimal level, performance of the individual starts to diminish. In their experiment, they discovered that rats could be motivated to complete a maze with slight electrical shocks. But, when the shocks were of the higher degree, their performance level decreased and they just ran about seeking for an escape.
It was clear from the experiment that arousal levels helped to focus attention and motivation on the task at hand, but only until an optimum point. One of the finest examples of this law is the anxiety you face during exam. Another final example of this law can be taken by looking at the athletic performance of an athlete. A football player hitting a penalty at the last minute of the game can be a nerve wrecking moment for the player.
At that instance, if his arousal level is at an ideal level, he will stay composed and scored a goal. Based on our daily activities, some tasks are much simpler to us while others require bit more work. We could be half asleep and still wash up well.
On the other hand, if we were to appear for a test or write a paper on some topic, it would require higher level of attention. Meaning, our optimal level of arousal for complex task, such as writing a paper is higher than the simpler task such as taking shower. At a track meet, it is almost impossible for sprinters to get too aroused for a race. The task is direct and uncomplicated: Run as fast as you can for a short distance.
On the other hand, a basketball player making a game-deciding free throw faces a more sensitive and complex task. Excessive arousal is almost certain to hurt his or her performance. Another example of the Yerkes Dodson law regarding complex and simpler task can be taken, again, in athletic performance. Excessive arousal or lack of it would definitely hurt his performance. The initial stage of the inverted U model the curve is low arousal level. This is the level of peak shown in the curve.
The performance level gradually increases as the curve heads towards the optinium level from the low arousal level, as shown in the graph. High Arousal Level This is the state when the arousal level of an individual is over the optimum balance. Our ability to focus on everything happening in our surrounding diminishes as our tension levels rise up, causing the performance to lower. The inverted U-curve model shown above is only for illustration, the reality however is slightly different from individual to individual depending on the situation.
A highly trained individual, confident in his skill, is more likely to cope well in high pressure situations, as the person would be able to rely on his well rehearsed responses. Personality of an individual also affects how well he handles pressure. Psychologists believe that extroverts are better at handling pressure than introverts. Likewise, introverts perform better in the lack of pressure.
The level of difficulty of the task is also another factor influencing the performance of an individual. As we have discussed earlier, it would be easier for an individual to take shower in half-sleepy state, but he would need to be in his A game to write an essay.
Also, the level of complexity of any task varies from one individual to the next. After studying the influencers and the U model, it can be concluded that influencers can be placed onto the model either lower or over the optimum arousal level. However, both lower and higher arousal levels can be maintained to the optimum balance.
Training, improvement of the required skill and experience can help avoid performance issues ont he right hand side of the graph, the higher arousal level. Motivation Emotion. What are other people reading?

Stress can even affect us physically, with weight loss or gain; aches, pains and muscle tension; frequent colds or infections; and even dizziness and palpitations.

The Yerkes-Dodson Law: Performance and Arousal — Exploring your mind
Yerkes-Dodson law suggests that elevated arousal levels can improve performance up to a certain point. Learn more about how this works and why sometimes a little bit of stress can actually help you perform your best. Have you ever noticed that you perform better when you are just a little bit nervous?
For example, you might do better at an athletic event if you are excited about participating or do better on an exam if you are somewhat anxious about your score. In psychology, this relationship between arousal levels and performance is known as the Yerkes-Dodson Law.
What impact can this have on our behavior and performance? The Yerkes-Dodson Law suggests that there is a relationship between performance and arousal. Increased arousal can help improve performance, but only up to a certain point.
At the point when arousal becomes excessive, performance diminishes. They discovered that mild electrical shocks could be used to motivate rats to complete a maze, but when the electrical shocks became too strong, the rats would scurry around in random directions to escape.
The experiment demonstrated that increasing stress and arousal levels could help focus motivation and attention on the task at hand, but only up to a certain point.
The anxiety you experience before an exam is one example of how the Yerkes-Dodson Law operates. An optimal level of stress can help you focus on the test and remember the information that you studied; too much test anxiety can impair your ability to concentrate and make it more difficult to remember the correct answers.
Athletic performance offers another great example of the Yerkes-Dodson Law. When a player is poised to make an important move, like making a basket during a basketball game, an ideal level of arousal can sharpen his performance and enable him to make the shot. When a player gets too stressed out, he might instead "choke" and miss the shot. So how do you determine what arousal levels are ideal? The key thing to remember is that this can vary from one task to the next.
Research has found, for example, that performance levels decrease earlier for complex tasks than for simple tasks even with the same levels of arousal. What does this mean exactly? If you are performing a relatively simple task, you are capable of dealing with a much larger range of arousal levels. Household tasks such as doing laundry or loading the dishwasher are less likely to be affected by either very low or very high arousal levels.
If you were doing a much more complex task, such as working on a paper for a class or memorize difficult information, your performance would be much more heavily influenced by low and high arousal levels. If your arousal levels are too low, you might find yourself drifting off or even falling asleep before you can even get started on the assignment.
Arousal levels that are too high could be just as problematic, making it difficult to concentrate on the information long enough to complete the task. Too much and too little arousal can also have an effect on different types of athletic performance tasks. While a basketball player or baseball player might need to control excessive arousal in order to concentrate on successfully performing complex throws or pitches, a track sprinter might rely on high arousal levels to motivate peak performance.
In such cases, the type of task and complexity of the task play a role in determining the optimal levels of arousal. Ever wonder what your personality type means?
