The behavioristic view of psychology has its roots in Associationism, Functionalism, and the Darwinian theory of Evolution. In associationism there is the belief that the mind learns by combining simple, irreducible elements through association. Both functionalism and Evolution stress the way that individuals adapt and adjust to the environment. John B. Watson developed Behaviorism in the early 20th century. He was influenced by Ivan P. Pavlov and Vladimir M. Bekhterev, both of whom worked with the conditioning of animals. Between 1920 and midcentury, behaviorism dominated psychology in the United States. By the 1950’s several psychologists such as B.F. Skinner came up with their own theories of learning and behavior based on laboratory experiments. (F. & W., 2021)
