How do you explain the Yerkes-Dodson Law?

How do you explain the Yerkes-Dodson Law?

According to what is known as “The Yerkes-Dodson law,” performance increases with physiological or mental arousal (stress) but only up to a point. When the level of stress becomes too high, performance decreases. There’s more: The shape of the curve varies based on the complexity and familiarity of the task.

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 does the general performance arousal curve illustrate?

The law dictates that performance increases with physiological or mental arousal, but only up to a point. 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.

What is Yerkes-Dodson Law AP Psychology?

The Yerkes-Dodson Law states that for easy tasks, the higher the level of physiological or mental arousal, the higher the performance. From that point on, a higher arousal hinders performance, because the person becomes too anxious and stressed and can’t concentrate on the task.

Which of the following is true of the Yerkes-Dodson law?

According 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. This enables us to run from danger before we fully feel the fear. A moderate level of anxiety is associated with optimal performance on exams.

What is inverted U hypothesis?

The ‘inverted U’ theory proposes that sporting performance improves as arousal levels increase but that there is a threshold point. Any increase in arousal beyond the threshold point will worsen performance. At high arousal levels, performance quality deteriorates.

What is an inverted U curve?

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.

What is optimum level of arousal?

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 arousal theory in criminology?

Arousal theory suggests that delinquents and criminals have suboptimal arousal levels. Thus, they are neurologically inclined to seek stimulation in a variety of ways and to tolerate more pain in satisfying their need for stimulation.

Who made Yerkes-Dodson law?

Robert Yerkes
The law was first described in 1908 by psychologists Robert Yerkes and John Dillingham Dodson. 2 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.

What is the Yerkes-Dodson law?

The Yerkes–Dodson law is an empirical relationship between pressure and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. The law dictates that performance increases with physiological or mental arousal, but only up to a point.

Can the Yerkes–Dodson law be decomposed as a bathtub curve?

For complex, unfamiliar, or difficult tasks, the relationship between arousal and performance reverses after a point, and performance thereafter declines as arousal increases. The effect of task difficulty led to the hypothesis that the Yerkes–Dodson Law can be decomposed into two distinct factors as in a bathtub curve.

Does Yerkes and Dodson’s correlation exist?

There has been research indicating that the correlation suggested by Yerkes and Dodson exists (such as that of Broadhurst (1959), Duffy (1957), and Anderson (1988) ), but a cause of the correlation has not yet successfully been established (Anderson, Revelle, & Lynch, 1989).
