The language acquisition faculty is a typically human capacity, unique to human begins. The LAD concept . Children are able to use their LAD to naturally intuit that some words act as verbs and others as nouns. The language acquisition device is a hypothetical tool in the brain that helps children quickly learn and understand language. [3], Critics say there is insufficient evidence from neuroscience and language acquisition research to support the claim that people have a language acquisition device as described above, and for the related ideas universal grammar and poverty of the stimulus. As new languages were studied in depth, the universal characteristics Chomsky hypothesized did not emerge.
