Final answer:
Noam Chomsky believes there is a language acquisition device programmed in the brain.
Step-by-step explanation:
Noam Chomsky believes that there is a language acquisition device (LAD) programmed in the brain. This mechanism, according to Chomsky, is an innate capacity that enables us to learn language. Chomsky's theory contradicts the behaviorist approach proposed by B.F. Skinner, who believed that language is learned through reinforcement. Chomsky argues that language acquisition is biologically determined and that we are born with a predisposition to acquire language.
