This equation is directly related to Lewin's field theory. Field theory is centered around the idea that a person's life space determines their behavior. [2] Thus, the equation was also expressed as B = f (L), where L is the life space. [4] In Lewin's book, he first presents the equation as B = f (S), where behavior is a function of the whole ...
In social science, force-field analysis provides a framework for looking at the factors ("forces") that influence a situation, originally social situations. It looks at forces that are either driving the movement toward a goal (helping forces) or blocking movement toward a goal (hindering forces). The principle, developed by Kurt Lewin, is a ...
Clark Leonard Hull (May 24, 1884 – May 10, 1952) was an American psychologist who sought to explain learning and motivation by scientific laws of behavior. Hull is known for his debates with Edward C. Tolman. He is also known for his work in drive theory. Hull spent the mature part of his career at Yale University, where he was recruited by ...
The theory states an individual's motivation for a task can be derived with the following formula (in its simplest form): = where , the desire for a particular outcome, or self-efficacy is the probability of success, is the reward associated with the outcome, is the individual’s sensitivity to delay and is the time to complete that task.
In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. [1] This limen is also known as the difference limen, difference threshold ...
Motivated reasoning (motivational reasoning bias) is a cognitive and social response in which individuals, consciously or sub-consciously, allow emotion-loaded motivational biases to affect how new information is perceived. Individuals tend to favor evidence that coincides with their current beliefs and reject new information that contradicts ...
Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus. It is often considered to supersede the Weber–Fechner law, which is based on a logarithmic relationship between stimulus and sensation ...
Need for power (nPow) is a term that was popularized by renowned psychologist David McClelland in 1961. McClelland's thinking was influenced by the pioneering work of Henry Murray, who first identified underlying psychological human needs and motivational processes (1938). It was Murray who set out a taxonomy of needs, including needs for ...
