Criticisms of Chomsky
1. Lack of scientific evidence innate understanding of structure of language 2. The rate of language development is affected by the degree of interactions with others 3. Does not take into account that a language acquisition support system is required 4. Chomsky put emphasis on grammar in sentence development rather than meanings
Benefits of Chomsky's Language Acquisition Device theory
Chomsky's LAD theory helps to explain how children develop language skills. It is based on nativist theory, which suggest that individuals are pre-programmed to develop in a certain way
Language Acquisition Device
Noam Chomsky proposed the LAD as the hypothetical part of the human mind that allows infants to acquire and produce language. He suggested that humans: -are born with a structure in their brain that enables them to acquire language -have a critical period for first language development in the first years of life -all follow the same pattern of language development -have an innate understanding of the structure of language (universal grammar) that is the basis for all languages
Language development from 2-3 years (early childhood)
links words together, for example 'me car', vocabulary increasing to approximately 200 words at 2 and a half
Language development from 0-3 months (infancy)
makes mouth movements in response to parent, cries to ask for food or comfort
