The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
Behavioral momentum is a theory in quantitative analysis of behavior and is a behavioral metaphor based on physical momentum.It describes the general relation between resistance to change (persistence of behavior) and the rate of reinforcement obtained in a given situation.
"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
The renewal effect is a phenomenon in which a change of context after extinction can cause a robust return of conditioned responding. There are three models in which the renewal effect is observed. The most common model is the "ABA renewal". Conditioning is conducted in one context (context A) and extinction is then conducted in a second ...
Ceballos pointed to the extinction of the passenger pigeon, which was the only species in its genus, as an example of how losing a genus can have a cascading effect on a wider ecosystem.
Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting. In the 20th century, operant conditioning was studied by behavioral psychologists, who believed that much of mind and behaviour is explained through environmental conditioning.
Exposure therapy can be investigated in the laboratory using Pavlovian extinction paradigms. Using rodents such as rats or mice to study extinction allows for the investigation of underlying neurobiological mechanisms involved, as well as testing of pharmacological adjuncts to improve extinction learning.

Dolf Zillmann began developing excitation-transfer theory in the late 1960s through the early 1970s and continued to refine it into the 21st century. [1] The theory itself is based largely on Clark Hull's notion of residual excitation (i.e., drive theory), Stanley Schachter's two factor theory of emotion, and the application of the three-factor theory of emotions.
