The document discusses the Behaviorist Theory of language acquisition, as proposed by B.F. Skinner. Skinner believed that language is learned through observable behaviors and interactions between individuals and their environment, without internal mental processes. He claimed that children acquire language by associating words with objects and responses through reinforcement. However, critics argue that Behaviorism cannot explain how children understand abstract concepts without examples, or how they can creatively generate new grammatical structures not heard before from adults. The document examines the key claims of Behaviorism and the main arguments that have been made against it.
