Pavlov's position toward American behaviorism

Pavlov's development of the conditional reflex theory coincided with the rise of American behaviorism. Substituting an objective physiology for a subjective psychology, Pavlov saw in the rise of American behaviorism a clear confirmation of his method and theory. But in the early 1930s, Lashley attacked Pavlov's theory of specific cerebral localization of function, proposing instead the concept of an internal cerebral organization; Guthrie objected to Pavlov's centralist interpretation of conditioning, proposing instead a peripheralist interpretation; while Hull challenged Pavlov's theory of sleep and hypnosis as the manifestations of inhibition. Pavlov replied with critiques of Lashley's, Guthrie's, and Hull's views, and, convinced that Lashley and Guthrie misunderstood his position, repeated his method's and theory's basic propositions. Yet, Pavlov never gave up the expectation that American behaviorism would accept his conditional reflex theory and saw in Hunter's 1932 statements a support of his assumptions.
