Three-term contingency
Contingency in operant conditioning
The three-term contingency (also known as the ABC contingency) in operant conditioning—or contingency management—describes the relationship between a behavior, its consequence, and the environmental context. The three-term contingency was first defined by B. F. Skinner in the early 1950s.[1] It is often used within ABA to alter the frequency of socially significant human behavior.
