Verbal Behavior is a theory developed by B.F. Skinner that focuses on how language is learned and used as a form of behavior. It emphasizes the role of environmental factors in shaping verbal skills, suggesting that language is a behavior that can be reinforced or modified through interactions with others. In this framework, different types of verbal responses are categorized, such as mands (requests), tacts (labels), and echoics (repeating). Each type serves a specific function and is influenced by the speaker's environment and experiences, highlighting the importance of social context in language development.
