According to Noam Chomsky, what is the innate biological endowment that allows children to acquire language rapidly?
Noam Chomsky proposed the Language Acquisition Device (LAD) as an innate biological capacity — not a specific brain organ, but a mental mechanism — that lets children rapidly acquire language from limited input. Inside the LAD sits Universal Grammar (UG), the abstract set of principles and parameters that all human languages share. A useful image: the LAD is the toolbox; Universal Grammar is the tools inside it. The LAD is the device that does the work of acquiring language; UG is the content the LAD applies. Without this innate equipment, learning a language from sparse input would be impossibly slow — which is Chomsky's main argument against behaviorist accounts of language learning.
Why the other choices are wrong
- B. Universal Grammar is what's INSIDE the LAD — the set of language principles. The LAD is the device that uses them. Toolbox vs. tools.
- C. Krashen's Input Hypothesis (i+1) is about comprehensible input being slightly above current level. It's about exposure, not the innate mechanism.
- D. Behaviorism (Skinner) denies innate language capacity and says language is learned by reinforcement. Chomsky's LAD was specifically built to argue against that view.
