All natural languages must share commonalities: all natural languages have nouns verbs prepositions adverbs etc. ^^suggests language universally has principles ex) all language has word for birds, has nouns, adj, verbs etc ; we are genetically wired for language acquisition (biological component) 1st year: infants can discriminate all phonemes from all languages. But will gradually lose non-relevant discriminations o ex) baby sucking experiment. Motherese o high pitch, slow rate, exaggerated intonation: helps children acquire language b/c it exaggerates boundaries. Major stages: holophrastic (one-word) stage, no syntax, a lot of gestures and crying to communicate, undergeneralization. Ex: only thinking your dog is a dog: overgeneralization. Pointing to any pet and calling it a dog: can understand multiple word phrases, telegraphic (two-word) stage, correct use of word order. Understanding more complicated utterances from others: learning syntax/rules, start learning syntactic/grammar rules.
