  2. Positive feedback - Wikipedia

    en.wikipedia.org/wiki/Positive_feedback

    Positive feedback (exacerbating feedback, self-reinforcing feedback) is a process that occurs in a feedback loop where the outcome of a process reinforces the inciting process to build momentum. As such, these forces can exacerbate the effects of a small disturbance.

  3. Perceptual control theory - Wikipedia

    en.wikipedia.org/wiki/Perceptual_control_theory

    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.

  4. Feedback - Wikipedia

    en.wikipedia.org/wiki/Feedback

    A negative feedback loop is one that tends to slow down a process, whereas the positive feedback loop tends to accelerate it. The mirror neurons are part of a social feedback system, when an observed action is "mirrored" by the brain—like a self-performed action.

  5. Cybernetics - Wikipedia

    en.wikipedia.org/wiki/Cybernetics

    Cybernetics is the transdisciplinary study of circular causal [1] processes such as feedback and recursion, where the effects of a system's actions (its outputs) return as inputs to that system, influencing subsequent action. [2]

  6. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    A closed-loop controller or feedback controller is a control loop which incorporates feedback, in contrast to an open-loop controller or non-feedback controller. A closed-loop controller uses feedback to control states or outputs of a dynamical system.

  7. Compulsion loop - Wikipedia

    en.wikipedia.org/wiki/Compulsion_loop

    A compulsion loop, reward loop or core loop is a habitual chain of activities that a user may feel compelled to repeat. Typically, this loop is designed to create a neurochemical reward in the user such as the release of dopamine .

  8. Negative feedback - Wikipedia

    en.wikipedia.org/wiki/Negative_feedback

    A simple negative feedback system is descriptive, for example, of some electronic amplifiers. The feedback is negative if the loop gain AB is negative.. Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by ...

  9. Self-fulfilling prophecy - Wikipedia

    en.wikipedia.org/wiki/Self-fulfilling_prophecy

    Self-fulfilling prophecies are an example of the more general phenomenon of positive feedback loops. A self-fulfilling prophecy can have either negative or positive outcomes. Merely applying a label to someone or something can affect the perception of the person/thing and create a self-fulfilling prophecy. [3]
