Positive feedback is used in digital electronics to force voltages away from intermediate voltages into '0' and '1' states. On the other hand, thermal runaway is a type of positive feedback that can destroy semiconductor junctions. Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions.
Positive feedback – Feedback loop that increases an initial small effect; Propaganda – Communication used to influence opinion; Publication bias – Higher probability of publishing results showing a significant finding; Recall bias – Type of cognitive bias; Self-handicapping – Cognitive strategy
Positive feedback occurs when the fed-back signal is in phase with the input signal. Under certain gain conditions, positive feedback reinforces the input signal to the point where the output of the device oscillates between its maximum and minimum possible states. Positive feedback may also introduce hysteresis into a circuit. This can cause ...
The positive reciprocity norm is a common social expectation in which a person who helps another person can expect positive feedback whether in the form of a gift, a compliment, a loan, a job reference, etc. In social psychology, positive reciprocity refers to responding to a positive action with another positive action (rewarding kind actions).
Bistability can be generated by a positive feedback loop with an ultrasensitive regulatory step. Positive feedback loops, such as the simple X activates Y and Y activates X motif, essentially link output signals to their input signals and have been noted to be an important regulatory motif in cellular signal transduction because positive ...
The positivity effect is the ability to constructively analyze a situation where the desired results are not achieved, but still obtain positive feedback that assists one's future progression.
Positive feedback loops play a role by switching cells from low to high Cdk-activity. The interaction between the two types of loops is evident in mitosis. While positive feedback initiates mitosis, a negative feedback loop promotes the inactivation of the cyclin-dependent kinases by the anaphase-promoting complex.
Self-verification is the drive to reinforce the existing self-image and self-enhancement is the drive to seek positive feedback. Both are served by confirmation biases. [123] In experiments where people are given feedback that conflicts with their self-image, they are less likely to attend to it or remember it than when given self-verifying ...
