Language development Flashcards
Hocket & Charles (1960)
differences that make our language special:
arbitrariness - no connection between sound and message
displacement - talking about things not present
productivity - create new utterances
duality of patterning - meaningless phonic segments combined to make something meaningful
forms
phonology and syntax/morphology
function
semantics and pragmatics
phones
differences in sounds we use and how we use them
phonemes
if a phone changed the meaning of a word
- infants born able to hear all phonemes - becomes specific to their own language
phonological development
7 months - canonical babbling (reduplicated sounds)
10 months - babbling reflects sounds of the environment
1 year - variegated babbling (sounds like words)
gaze following
18 months
checking where people are looking when they are speaking
joint attention
9 months
2 or more people attend to something and are mutually aware of it
- predicts age of language production
pointing
9-14 months
imperative - tell someone to do something
declarative - inform someone about something
index finger - predicts vocabulary development
open handed pointing - delay
words
10-15 months - begin to produce words
slow until 50-100 words in lexicon
6 years - 10-14’000 words in lexicon
8-10 years - 12 new words per day
errors in speech
spoonerisms - changes letters of two words
malapropisms - word replaces similar sounding word
semantics
meaning of a word and how to use it
errors of scope
semantic issues
underextentions (too little detail) or overextensions (too much detail - over applying)
how children learn semantics/meaning of words
learn to make assumptions - more likely to mean the whole rather than a part of an object
associative learning - word used when the same object is present
social cues - if you have been looking for something, find it and someone says the word
linguistic cues - other words give clues about reference
mutual exclusivity - knowing what other words mean = vital
