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.
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]
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.
Obtaining – Primary-Positive Control; Obtaining is defined as “the perceived ability to obtain positive outcomes”. It is dependent on (1) the degree of personal control over good things, (2) the personal responsibility for good things, (3) the frequency with which good things occur, and (4) the likelihood of good things occurring.
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.
ACT-R (pronounced /ˌækt ˈɑr/; short for "Adaptive Control of Thought—Rational") is a cognitive architecture mainly developed by John Robert Anderson and Christian Lebiere at Carnegie Mellon University. Like any cognitive architecture, ACT-R aims to define the basic and irreducible cognitive and perceptual operations that enable the human ...
Endogenous control works top-down and is the more deliberate attentional system, responsible for divided attention and conscious processing. [ 13 ] One major focal point relating to attention within the field of cognitive psychology is the concept of divided attention.
Control theory dates from the 19th century, when the theoretical basis for the operation of governors was first described by James Clerk Maxwell. [1] Control theory was further advanced by Edward Routh in 1874, Charles Sturm and in 1895, Adolf Hurwitz, who all contributed to the establishment of control stability criteria; and from 1922 onwards ...
