High Quality Content by WIKIPEDIA articles! Verbal Behavior is a 1957 book by psychologist B.F. Skinner, in which he analyzes human behavior, encompassing what is traditionally called language, linguistics, or speech. For Skinner, verbal behavior is simply behavior subject to the same controlling variables as any other operant behavior, although Skinner differentiates between verbal behavior which is mediated by other people, and that which is mediated by the natural world. The book Verbal Behavior is almost entirely theoretical, involving little experimental research in the work itself. The book Verbal Behavior 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 have occurred since its original publication, particularly in the past decade.
