What is Yerkes-Dodson Law of arousal in psychology?

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. Different tasks require different levels of arousal for optimal performance, research has found.

What is an example of arousal theory in psychology?

For example, if our levels drop too low we might seek stimulation by going out to a nightclub with friends. If these levels become too elevated and we become overstimulated, we might be motivated to select a relaxing activity such as going for a walk or taking a nap.

What is Yerkes-Dodson Law of arousal in psychology quizlet?

The Yerkes-Dodson Law of Arousal, also known as Arousal Theory, states that an organism’s performance can be improved if that organism is aroused in some manner. There is more arousal (stress, excitement) during the real games which increases their performance.

What are the 4 theories of arousal?

Theories of Arousal

Drive Theory.
Inverted U hypothesis.
Catastrophe Theory.
Zone of Optimal Functioning (ZOF) Theory.

What is optimal 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 the best level of arousal for performance?

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 are the three theories of arousal?

The widely known theories include: The Drive Theory, The Inverted U-Hypothesis, The Catastrophe Theory and Individual Zones of Optimal Functioning (IZOF). Read and/or listen to the information on the these three theories by clicking on the links below.

What are the different levels of arousal?

The level of mental arousal is the level of excitement, anticipation, stress, aggression, apprehension and nervousness. It refers to the state of mental preparedness for participation in an activity.

What is divided attention in psychology quizlet?

Divided attention. The ability to pay attention to, or carry out, two or more different tasks simultaneously. Early selection model. Model of attention that explains selective attention by early filtering out of the unattended message.

What is the two factor theory quizlet?

The two-factor theory of emotion states that the physiological arousal in different emotion is entirely the same and we label our arousal according to the cognitions we have available. They argue that all three propositions were supported.

What are the 3 theories of arousal?

Which theory explains that performance is best with a moderate not too high and not too low level of arousal?

The 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.

How does the Yerkes-Dodson law relate to performance?

How is the Yerkes Dodson law decomposed?

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. The upward part of the inverted U can be thought of as the energizing effect of arousal.

Is there a correlation between Yerkes and Dodson?

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).

Why is the Yerkes-Dodson law called the inverted U?

What Yerkes and Dodson describe is often illustrated graphically as a bell-shaped curve that increases and then decreases with higher excitation levels. This explains why many people know the Yerkes-Dodson law as the inverted U model. Due to the differences in tasks, the shape of the curve can vary.
