Document Summary

Speech perception: there are 3 problems we need to deal with: lack of invariance: letters sound the same, problems of speakers variability: people sound different, the segmentation problem: no clear breaks between words, continuous. We have categorical perception: we hear sharp contrasts between speech sounds even though they vary continuously. Speech perception is very top down, we will fill in the gaps (i. e. mcgurk, phonemic restoration effect) 0-4 months with facial movements, and recognizing when sounds are broken into words. Productive language: babbling in multilingual sounds and gestures. Babbling sounds more like the parents/ household language. One word stage: understanding and beginning to say many nouns. Two word telegraphic speech: adding verbs, and making sentences but missing. Nature (children must construct) vs. nurture (learn their mothers tongue) Social learning process: parents, use high pitched intonations (motherese, name objects and ask questions, operant conditioning, positive reinforcement of appropriate language, non reinforcement or correction of inappropriate language.
