Paraphrase this:
The main principle of innatist perspectives on language acquisition is the notion that humans are born with an innate ability to acquire language. This perspective is often associated with Noam Chomsky's theory of Universal Grammar, which posits that there are underlying principles common to all languages that children are predisposed to acquire (Pinker, 1994). According to this view, children are able to rapidly and effortlessly learn the complex rules of language because they have an inborn capacity for language learning (Chomsky, 1988).
