Child Language Acquisition
Noam Chomsky - Chomsky believed that children acquiring a language was innate and they had a natural ability to create sentences which he said must have 'already been imprinted on the mind'. He called this ability the 'language acquisition device' and this encodes grammatical structures in the brain so when a child learns new vocabulary, they simply apply it to the structure they already know. He believed this because he noticed in his research that children never get their subjects, verbs and objects in the wrong order; they would notice if an adult purposely said an grammatically incorrect sentence; and also that they say some things which are incorrect grammatically for example 'I drawed' instead of 'I drew' but they could not have repeated this from hearing it, therefore learning is not just through imitation.
David Crystal - Crystal's theory of child language acquisition is that a child will learn in five different stages. Stage one is where children learn to say things for three different reasons: to get something they want; to get someone's attention; or to draw attention to something. Stage two is when the child learns to use interrogatives and usually start with 'what', or 'where'. Stage three involves lots of questions being asked and the development of state of actions and simple verbs such as 'listen' and 'know'. Stage four is when the child develops the ability to use more complex grammatical structures and can explain things, ask 'why' questions or making lots of requests. Stage five is when the child has fully developed language and uses it for all its purposes: to give information and explain things, ask and answer questions, requesting, expressing etc.
Jean Aitchison - Aitchison believed that a childs development of language is biologically organised and every child follows a similar pattern. She identified three stages of child language acquisition. One stage is labeling: this involves linking sounds to objects and associating a name to something. The second stage is packaging: this involved understanding the meaning of a word and the range of the meaning. The last stage is called network building: which is the understanding of the connection between words, and understanding that words have synonyms and antonyms.
B.F. Skinner - Skinner believed that language acquisition are learned through associating events known as classical conditioning. This is said to be done by children associating objects with sounds or words. They are then rewarded by their parents by smiling or praising by their parents, which is called operant conditioning, as a positive reinforcement is likely to encourage the behaviour to be repeated.
Neural networks - Some cognitive neuro-scientists have created neural networks that can some aspects acquire language. They are not programmed just exposed to lots of expamples of language. They are able to learn grammatical structures and make past tense forms with verbs. This supports the study that language is learned and developed as we grow up, not that we are born with the ability.
