In 1957, Skinner published Verbal Behavior, a theoretical extension of the work he had pioneered since 1938. This work extended the theory of operant conditioning to human behavior previously assigned to the areas of language, linguistics and other areas. Verbal Behavior is the logical extension of Skinner's ideas, in which he introduced new functional relationship categories such as intraverbals, Autoclitics, mands, tacts and the controlling relationship of the audience. All of these relationships were based on operant conditioning and relied on no new mechanisms despite the introduction of new functional categories.
