Child Lang Flashcards
Imitation theory
Skinner Born knowing nothing and learn through copying Trial and error Get rewarded for correct sounds Phonological development
Examples for and against imitation theory
Explains accents
Melodic utterances
‘Fis’ phenomenon
Doesn’t explain babbling, virtuous errors or grammar acquisition
Innateness theory
Chomksy
Ability to learn is innate
Born with Language Acquisition device (LAD)
We’re born knowing basic language structures
Universal grammar
Examples for and against innateness theory
Virtuous errors
Babbling
Regression model
Wug test
Doesn’t explain accents and requires an input to the LAD, need for interaction
Input theory
Bruner
Focus on language used by parents
Language acquisition support system (LASS) and child directed speech
Interactions for turn taking and convo development
Examples for and against input theory
Pragmatics and CDS
Changing in intonations, repetition, questions
Genie had no language (no interaction)
Doesn’t explain that some cultures don’t use CDS but kids still develop languages
Cognitive theory
Piaget
Learn object permanence to expand vocabulary
Develop concepts before language
Examples for and against cognitive theory
Majority of first 50 words are physical objects
Semantics
Over extensions
Learning ‘ing’ before any other inflection (here and now)
Doesn’t explain sentence or grammar acquisition or delayed mental development
Usage-based approach
Ibbotson and Tomasello
Against Chomsky
Children learn chunks of language
Put chunks together to form sentences
Examples for and against useage-based
Pragmatics
Predicting what people might say
Missing out less used auxiliaries and determiners
Doesn’t explain virtuous errors and generalisations
Phonological development
Sounds and pronunciations 1st year Pre-verbal stages Realisation rules Olmsted’s research Browns ‘fis’ phenomenon
Pre-verbal stages
Biological noises (0-8 weeks - vomiting burping crying etc universal) Cooing and laughing (6-8 weeks - settled state, short vowel or consonant sounds, more melodic and vocal muscle control develops) Vocal play (single controlled vowel or consonant like sounds) Babbling (7-8 months - combinations of vowels and consonants similar to native language, phonemic contraction, deaf babies babble) Melodic utterances (end of 1st year, melody intonation rhythm develop, sounds like native language, has different functions)
Realisation rules (8)
Reduplication (repeating a syllable e.g. dog = dodo)
Reduction /deletion of monosyllables (getting rid of last consonant sounds e.g. noise = noi)
Consonant cluster deletion (removing clustered consonants to keep CV rule e.g. plastic = patic)
Substitution (replacing end consonants for vowels e.g. button = butu)
Addition ( adding vowels to make it easier to say e.g. pig = pige)
Assimilation (making consonant sounds similar e.g. yellow = lellow)
Voiced / Voiceless consonants (voiced at beginning voiceless at the end e.g. dog = dok)
Weak syllable deletion (unstressed syllables are missed out e.g. behind = hind)
Olmsted’s research
Age 2 = plosives produced /p/ /b/ /d/ /m/
Age 2.5 = /k/ /g/
Age 3 = start fricritives /f/ /s/ /I/
Age 3.5 = /S/ /tS/
Age 4.5 = /d3/ /v/ /z/ /r/
Age 6 = /0/ /3/
Learn easier to say sounds first at the front of the mouth then learn sounds at back of mouth which are harder to say
See people saying sounds at front of mouth - copy mouth movements
Browns ‘fis’ phenomenon
Brown said ‘fish’ kid said ‘fis’
Brown said ‘fis’ kid said no ‘fis’
Kids know the correct pronunciation but can’t always produce the correct sounds
