What is the Wundt curve?
a bell-shaped curve illustrating that as a stimulus intensity (e.g., light) increases from low to moderate levels, its effect is pleasant or rewarding, but that as it increases to higher levels, its effect is unpleasant and even painful.
What are the limitations of the inverted U theory?
Problems with inverted ‘U’ Theory Critics question if optimal arousal always occurs at the mid-point of the curve. One curve does not explain the different optimal levels of arousal needed for simple and complex tasks.
Which type of aesthetics focuses on dimensions enclosure complexity and order?

How does the inverted U theory affect performance?
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 low arousal levels, performance quality is low.
What is inverted U theory in economics?
According to the Kuznets’ Inverted U-hypothesis, as per capita national income of a country increases, in the initial stages of growth, inequality in income distribution rises and after reaching the highest degree in the intermediate level the income inequality falls.
What does the inverted U mean?
What does an inverted U mean?
In motivation: The inverted-U function. The relationship between changes in arousal and motivation is often expressed as an inverted-U function (also known as the Yerkes-Dodson law). The basic concept is that, as arousal level increases, performance improves, but only to a point, beyond which increases in arousal lead…
Who made the inverted U theory?
Broadhurst, P. L. (1957). Emotionality and the Yerkes-Dodson law. Journal of experimental psychology, 54(5), 345. Broadhurst, P. L. (1959).
What is the inverted theory?
Key Points. 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 does the upside down U mean in Venn diagrams?
Using the Venn diagram, find the intersection of 𝐴 and 𝐶. This upside-down U is a symbol for intersection. And an intersection is all the common elements between the two sets.
How does the inverted U theory work?
Who invented inverted theory?
The Inverted-U Theory was created by psychologists Robert Yerkes and John Dodson in 1908.
What did Berlyne contribute to experimental psychology?
Berlyne made important experimental and theoretical contributions to an astounding number of areas in experimental psychology (broadly defined), including exploratory behavior, curiosity, physiological arousal, attention, play behavior, humor, thinking, and experimental aesthetics.
What is the focus of Berlyne’s work?
Thus, most of Berlyne’s work focused on the effects of and reactions to curiosity and arousal, rather than focus on the ideas as states of being. His work focused on “why organisms display curiosity and explore their environment, why they seek knowledge and information”.
