Final answer:
Nativists, such as Noam Chomsky and his theory of the Language Acquisition Device (LAD), argue that language development is largely biologically determined.
Step-by-step explanation:
Nativists, such as Noam Chomsky and his theory of the Language Acquisition Device (LAD), argue that language development is largely biologically determined. Chomsky proposed that humans are born with an innate capacity for language and possess a specific brain mechanism that allows them to learn language effortlessly. According to Chomsky, this LAD enables children to acquire the grammatical rules and structures of language without explicit instruction or reinforcement. This theory suggests that language development is influenced by nature rather than environmental factors.
