Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning. In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. [ 1 ]
Operant conditioning, also called instrumental conditioning, is a learning process where voluntary behaviors are modified by association with the addition (or removal) of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or extinction .
Extinction is considered successful when responding in the presence of an extinction stimulus (a red light or a teacher not giving a bad student attention, for instance) is zero. When a behavior reappears again after it has gone through extinction, it is called spontaneous recovery. It (extinction) is the result of challenging behavior(s) no ...
Skinner described operant conditioning as strengthening behaviour through reinforcement. Reinforcement can consist of positive reinforcement, in which a desirable stimulus is added; negative reinforcement, in which an undesirable stimulus is taken away; positive punishment, in which an undesirable stimulus is added; and negative punishment, in which a desirable stimulus is taken away.

The conditioned emotional response is usually measured through its effect in suppressing an ongoing response. For example, a rat first learns to press a lever through operant conditioning. Classical conditioning follows: in a series of trials the rat is exposed to a CS, often a light or a noise. Each CS is followed by the US, an electric shock.
Bailey's husband Bob continued to teach seminars they developed and the Bailey & Bailey Operant Conditioning Workshops which they began together. [38] [39] The Archives of the History of Psychology in Akron, Ohio, and the Smithsonian Math and Science Museum in Washington, D.C., now house collections of Bailey's documents and items. [40]
Robert A. Rescorla (May 9, 1940 - March 24, 2020) [1] [2] was an American psychologist who specialized in the involvement of cognitive processes in classical conditioning [3] focusing on animal learning and behavior. [4] One of Rescorla's significant contributions to psychology, with co-creator Allan Wagner, was the Rescorla-Wagner Model of ...
In this regard, patients' avoidance behaviors can become reinforced – a concept defined by the tenets of operant conditioning. Thus, the goal of systematic desensitization is to overcome avoidance by gradually exposing patients to the phobic stimulus, until that stimulus can be tolerated. [ 3 ]
