Behaviorism was introduced by the American psychologist John B. Watson in 1913. Though he was considered the originator of the theory, two other researchers Pavlov (1927) and Skinner (1938) contributed greatly to it by their research and theories.
B.F. Skinner was an American Psychologist, behaviorist,
inventor and social philosopher. He was the professor of Psychology at Harvard
University from 1958 to 1974. His behaviorist theory of learning is based on
the idea that people learn through the consequences of their actions and that
reinforcement and punishment are key to shaping behavior.
