The school of psychology maintains that behaviors as such can be described scientifically without resource either to internal physiological events or to hypothetical constructs such as the mind.

Behaviorism comprises the position that all theories should have observational correlates but that there are no philosophical differences between publicly observable processes (such as actions) and privately observable processes (such as thinking and feeling).

From early psychology in the 19th century, the behaviorist school of thought ran concurrently and shared commonalities with the psychoanalytic and Gestalt movements in psychology into the 20th century; but also differed from the mental philosophy of the Gestalt psychologists in critical ways.[citation needed] Its main influences were Ivan Pavlov, who investigated classical conditioning, Edward Lee Thorndike, John B. Watson, had an affair with Raynor,  who rejected introspective methods and sought to restrict psychology to experimental methods, and B.F. Skinner who conducted research on operant conditioning. In the second half of the twentieth century, behaviorism was largely eclipsed as a result of the cognitive revolution.
