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.
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.
Evidence from one study supports 5 independent genetic mechanisms underlying the Ryff facets of this trait, leading to a genetic construct of eudaimonia in terms of general self-control, and four subsidiary biological mechanisms enabling the psychological capabilities of purpose, agency, growth, and positive social relations.

Positive health of a person is defined as the ability to live long in good health without activity limitation. [1] This implies the availability of mechanism in the body to thwart the ailments and to minimize their adverse effect if they strike. The concept has evolved over time and has seen significant changes.
It concerns the brain cells, structures, components, and chemical interactions that are involved in order to produce actions. [4] Psychologists in this field usually focus their attention to topics such as sleep, emotion, ingestion, senses, reproductive behavior, learning/memory, communication, psychopharmacology, and neurological disorders ...
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).
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
Positive climate change feedbacks amplify changes in the climate system, and can lead to destabilizing effects for the climate. [2] An increase in temperature from greenhouse gases leading to increased water vapor (which is itself a greenhouse gas) causing further warming is a positive feedback, but not a runaway effect, on Earth.
