Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment.
William T. Powers (August 29, 1926 – May 24, 2013) was a medical physicist and an independent scholar of experimental and theoretical psychology [1] [2] [3] who developed the perceptual control theory (PCT) model of behavior as the control of perception.
The Method of Levels originated in Bill Powers’ phenomenological investigations into the mobility of awareness relative to the perceptual hierarchy. [3] He prepared a description of it for his 1973 book, Behavior: The Control of Perception, but the editor persuaded him to remove that chapter and the chapter on emotion. [4]
In contrast to the frequency domain analysis of the classical control theory, modern control theory utilizes the time-domain state space representation, [citation needed] a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations. To abstract from the number of inputs ...
Common coding theory is a cognitive psychology theory describing how perceptual representations (e.g. of things we can see and hear) and motor representations (e.g. of hand actions) are linked. The theory claims that there is a shared representation (a common code) for both perception and action.
For example, there should be a section on PCT and sociology, which should be put in relationship with Control_theory_(sociology), and then the disconnected subsection of references to PCT and sociology could be properly handled. The article Control theory (sociology) has some things that seem a bit garbled to me, quite apart from not mentioning ...
Patrick Carlin, a comedy writer and performer who was a major influence on his younger brother George Carlin, died Saturday at Kaiser Permanente hospital in Hollywood. He was 90. Carlin’s death ...
Affect control theory's computer program predicts the plausible re-identifications, thereby providing a formal model for labeling theory. The sentiment associated with an identity can change to befit the kinds of events in which that identity is involved, when situations keep arising where the identity is deflected in the same way, especially ...
