Language acquisition device

From Teflpedia

The language acquisition device (LAD) is a module of the human mind posited to account for children's innate predisposition for language acquisition.[1] It was first proposed by Chomsky in the 1960s.[2] It is generally accepted as scientific theory but many of the details are yet to be worked out.

The critical period hypothesis holds that children have highly efficient LADs but that these become defective after the child has passed through developmental periods.
