Kenneth MacCorquodale (June 26, 1919 - February 28, 1986) was an American psychologist who played a major role in developing scientifically validated operant conditioning methods. He was a student of B. F. Skinner at the University of Minnesota. [1] [2]
To study operant conditioning, he invented the operant conditioning chamber (aka the Skinner box), [8] and to measure rate he invented the cumulative recorder. Using these tools, he and Charles Ferster produced Skinner's most influential experimental work, outlined in their 1957 book Schedules of Reinforcement .
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 .
Contingency management (CM) is the application of the three-term contingency (or operant conditioning), which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
The three-term contingency (also known as the ABC contingency) is a psychological model describing operant conditioning in three terms consisting of a behavior, its consequence, and the environmental context, as applied in contingency management. The three-term contingency was first defined by B. F. Skinner in the early 1950s. [1]
Central to operant conditioning is the use of a Three-Term Contingency (Discriminative Stimulus, Response, Reinforcing Stimulus) to describe functional relationships in the control of behavior. Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating.
In operant conditioning, if a piece of food is presented to a dog after the dog makes a particular motor response, the dog will come to make that motor response more frequently. For Staats, these two types of conditioning are not separate, they interact. A piece of food elicits an emotional response.
The Behavior of Organisms is B.F. Skinner's first book and was published in May 1938 as a volume of the Century Psychology Series. [1] It set out the parameters for the discipline that would come to be called the experimental analysis of behavior (EAB) and Behavior Analysis.
