Noam Chomsky departed from B. F. Skinner’s beliefs about language, arguing that

a. language is only possible during a critical period, and not afterward.

b. simple mastery of phonemes and morphemes does not equal a language.

c. the rules of syntax were more crucial to understanding language than semantics.

d. language is innate and not merely developed through reinforcement.

e. language is just as possible in animals as in humans, given enough time and training.
