How does Yerkes-Dodson law explain emotional arousal?
The 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.
What is the optimal level of arousal in the Yerkes-Dodson law?
Optimal Levels of Arousal (i.e. Stress) Research shows that moderate arousal is generally best; when arousal (stress) is very high or very low, performance tends to suffer. The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M.
What does the inverted U hypothesis predict?
The Inverted U Hypothesis suggests that optimal performance occurs at an intermediate level of arousal while both low and high levels of arousal will result in impaired performance. However, in general one could expect that athletes may perform badly because they are over- or under-aroused.
What are the 3 bell curve of Yerkes-Dodson law?
Yerkes-Dodson curve The left side of the curve represents low arousal, or stress. The right side represents high arousal. And at the center is a medium level of arousal. The vertical line on the left side goes from poor performance (at the bottom) to peak performance (at the top).
What is the inverted U law?
The Inverted-U Theory illustrates the relationship between pressure and performance. Also known as the Yerkes-Dodson Law, it explains how to find the optimum level of positive pressure at which people perform at their best. Too much or too little pressure can lead to decreased performance.
What is the arousal theory?
The arousal theory of motivation suggests that people are driven to perform actions in order to maintain an optimum level of physiological arousal. Other people may do better with much lower arousal levels, so they might feel compelled to seek out soothing and relaxing activities.
What is optimal arousal theory?
Optimal arousal is a psychological construct referring to a level of mental stimulation at which physical performance, learning, or temporary feelings of wellbeing are maximized (Smith 1990). It can also be described as the degree of energy release and the intensity of readiness.
What is Kuznets inverted U hypothesis?
Kuznets’ inverted-U hypothesis implies that economic growth worsens income inequality first and improves it later at a higher stage of economic development. Previous research used cross-sectional data to test not only the Kuznets’ hypothesis, but also empirical validity of other factors and provided mixed conclusions.
Is this a U-shaped or inverted U-shaped relationship?
The so called “inverted U-shaped dose-effect curve” (IUSDEC) is a nonlinear relationship which has been frequently reported when studying the negative or positive actions of pharmacological and non-pharmacological treatments on cognitive functions and memory.
How did the Yerkes and Dodson experiment affect performance?
In their experiment, Yerkes and Dodson discovered that electric shocks could motivate rats to complete a maze. However, when they overly shocked them, their performance level decreased and they simply just tried to escape. The experiment demonstrated that arousal levels helped to focus attention on the task at hand, but only up to a certain point.
Who is the founder of the Yerkes Dodson law?
Psychologists Robert M. Yerkes and John Dillingham Dodson developed this law in 1908. The Yerkes-Dodson law establishes that performance increases with physiological or mental arousal, but only up to a certain point. When excitation levels become too high, performance decreases.
How did Yerkes and Dodson come up with the idea of habit?
Yerkes and Dodson formed their theory while performing experiments on mice. Using mild electric shocks, they were able to teach the mice to learn a task, which they called a “habit,” more quickly.
What did Robert Yerkes and John Dillingham Dodson discover?
In 1908, 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. They found that if the shocks were too strong, the rats would lose their motivation to complete the maze and instead move about randomly trying to escape.
