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.
A key insight of PCT is that the controlled variable is not the output of the system (the behavioral actions), but its input, "perception". The theory came to be known as "perceptual control theory" to distinguish from those control theorists that assert or assume that it is the system's output that is controlled.
Client perception: The client perceives, to at least a minimal degree, the therapist's unconditional positive regard and empathic understanding. The three conditions specific to the therapist/counselor came to be called the core conditions of PCT: therapist congruence, unconditional positive regard or acceptance, and accurate empathic ...
Perceptual control theory (PCT) is a psychological theory of animal and human behavior originated by William T. Powers. In contrast with other theories of psychology and behavior, which assume that behavior is a function of perception – that perceptual inputs determine or cause behavior – PCT postulates that an organism's behavior is a ...

The layered protocol theory (LPT), [1] which is a special version of perceptual control theory (PCT), brings these views together by suggesting that users interact with a system across several layers by sending messages. Users interact with components on high layers by sending messages, such as pressing keys, to components operating on lower ...
