Verbal Behavior is a 1957 book by psychologist B. F. Skinner, in which he inspects human behavior, describing what is traditionally called linguistics. The book Verbal Behavior is almost entirely theoretical, involving little experimental research in the work itself. It was an outgrowth of a series of lectures first presented at the University of Minnesota in the early 1940s and developed further in his summer lectures at Columbia and William James lectures at Harvard in the decade before the book's publication. A growing body of research and applications based on Verbal Behavior has occurred since its original publication, particularly in the past decade.
