Step 1: Identify the Psychological School of Thought:
The query requires the identification of the psychological school associated with John B. Watson.
Step 2: Elucidate the Rationale:
John B. Watson is recognized as the progenitor of behaviorism. In his pivotal 1913 publication, "Psychology as the Behaviorist Views It," he advocated for psychology to operate as an objective, experimental discipline within natural science. He dismissed the investigation of consciousness and introspection, methods characteristic of structuralism, and posited that psychology's purview should exclusively encompass observable actions.
Structuralism (Titchener) concentrated on the fundamental components of consciousness.
Functionalism (William James) examined the functions of consciousness and behavior.
Psychoanalysis (Freud) delved into the unconscious mind.
Watson's contributions, exemplified by the renowned "Little Albert" study, solidified behaviorism's prominence in psychology.
Step 3: State the Conclusion:
John B. Watson is a proponent of behaviorism.
