LIN 401 Lecture Notes - Lecture 19: Jean Berko Gleason, Language Development, Neurotypical
Document Summary
Language acquisition - based on social interaction and language exposure, but supported by powerful neurological systems. Poverty of the stimulus - adults use a lot of sentences around a child, but never enough to demonstrate that language is infinite. There are types of language mistakes that children never make. All neurotypical children go through the same types of language acquisition stages, although they all develop differently. By the age of six months, children have narrowed down the usage of phonemes in their language from all possible phonemes to phonemes that are actually used. Babbling sounds more and more like baby"s language as they get older. They then develop the use of stress patterns, intonation, and word boundaries. *babies understand much more than they can say* Overextension - overapplication of a word - too many meanings. A child may call every four legged animal a kitty. Underextension - not applying a word generally enough.
