An Updated Bibliography of John B. Watson.

John B. Watson is a significant figure in the history of psychology. Although some scholars contest the thesis that he was the creator of the behaviorist movement, he was undoubtedly a great popularizer of behaviorism, and many of the psychologists who proposed new varieties of behaviorism admit that they were directly influenced by him. Most psychologists, and probably all behavior analysts, read and heard about Watson at some point in their apprenticeship. Nevertheless, Watson's works are usually misunderstood, mainly because most of his publications are unknown to the majority of psychologists and historians of psychology. The publication of a more complete and precise bibliography may help to solve this problem. This article presents an updated bibliography of John B. Watson's published works; it contains 209 entries, including 50 new ones compared with the last, and at that point the most developed, bibliography available. The bibliography we present here is offered to assist researchers, historians, and other scholars in taking a broader view of Watson's behaviorism and its impact on academic and lay audiences. © Association for Behavior Analysis International 2020.
