PREVERBAL
before words, language before functional speech is learnt
first noises e.g. crying - noise for a physical reason
begins to exercise vocal chords
first recognition of discourse
cooing from 2 months - experimenting with noises
noises forerun babbling
babbling from 6 months - vowel and consonant sounds
reduplicated babbling comes first - repeated same sound e.g. bababa
variegated babbling later on - variation in consonant sounds
HOLOPHRASTIC
one word used to communicated
first word around first birthday
12 - 18 months
convey whole sentence with one word
often mummy, daddy, concrete nouns
TWO WORD
using two words by combining words learnt in holophrase
from 18 months, start to develop 2 words together with meaning
lang becomes clearer and more defined
begin to understand grammar and relationship between words used
‘vocab splurt’ or ‘ naming explosion’
cognitive change occurs from 18 months, understand words have names and gain ‘naming insight’
from slower lexical development to more rapid acquisition
by age 2, may have 300 words
TELEGRAPHIC
recognising meaning, stringing more words together
age 2 - move from 2 words to longer and more complete utterances - like a telegram (meaning in minimum words)
more content words to convey meaning
omit grammatical words which are needed for structural accuracy not meaning e.g. me going on trip
POST-TELEGRAPHIC
final stage, grammatically more complex combinations
age 3
increasingly like an adult
grammatical words alongside content words
by age 4, largely accurate and grammatically complex sentences
PHONOLOGY
protowords
made up words used to represent a word they cannot yet pronounce e.g. ray ray for raisins
PHONOLOGY
communicative competence
ability to form accurate and understandable utterances using the grammar system
PHONOLOGY
content and grammatical words
content - vital to meaning
grammatical - necessary for structural accuracy
PHONOLOGY
vegetative stage
features - sounds of discomfort or reflexive actions
e.g. crying, coughing, burping, sucking
0-4 months
PHONOLOGY
cooing stage
features - comfort sounds, vocal play
e.g. grunts and sighs become vowel like - ‘coos’, laughter, hard consonants and vowels, pitch and loudness practised with squeals, yells and shouts
4-7 months
marks beginning of prosodic features (intonation, pauses, stress, rhythm)
PHONOLOGY
babbling
features - extended sounds, resembling-like sequences, repeated patterns
e.g. sounds linking to own language, reduplicated and non reduplicated sounds
6-12 mnths
PHONOLOGY
proto-words
features - word like vocalisations
e.g. made up words
9-12 mnths
INTONATION
gives listener clues towards meanings of a message
pitch signals feelings (rising pitch shows excitement) or to give listener notice that giving up turn to speak
e.g. rising intonation indicates q
ALAN CRUTTENDEN
1974
compared adults and children to see if could predict football results from listening to intonation placed on teams
adults accurately predicted
children under 7 less accurate
shows children not born with innate understanding of intonation and it is learnt
DESMOND MORRIS
first 6 mnths - gurgles and babbles same regardless of nationality
deaf children create same sounds
changes at 6 mnths - become increasingly attuned to variations in rhythm of particular lang and babble represents this lang
shows can learn any lang at this stage
PHONEMIC EXPANSION
early developments allow child to increase variety of sounds produced
PHONEMIC CONTRACTION
reduce sounds to only those needed for their lang
PATRICIA KHUL
potential for lang learning much easier for infants
learn what sounds used in the lang
adults = cultural bound citizens so harder to be ecposed to diff sounds
6-8 mnths r-l sounds same in amercian and japanese babies
10-12mnths starts to sound diff
babies absorb statistics of their lang and repeat the sounbds used in high frequencies - r-l important to american babies
same study with american and taiwanese babies
american babies exposed to taiwanese and ab;e to grasp sounds when tested on
JUST AUDIO LEARNING - no learning
VIDEO LEARNING - no learning
ONLY LEARN WITH REAL PERSON TEACHING
infants need sounds and interaction
development in use of vowels and consonants
2.5 - all vowels and 2/3 consonants ,astered
4 - difficulty with hew consonants
6-7 - confident use
consonants first used correctly at starts of words
more difficulty with consonants at end
e.g. push vs rip
EARLY PHONOLOGICAL ERRORS
deletion
omitting final consonant in words
e.g. do(g)
EARLY PHONOLOGICAL ERRORS
assimilation
changing one consonant or vowel for another
common with early plosive sounds like b and d
e.g. gog for dog
EARLY PHONOLOGICAL ERRORS
addition
adding an extra vowel sound to the end of words
cvcv pattern
EARLY PHONOLOGICAL ERRORS
deletion of unstressed syllables
often deleted
e.g. nana for banana
EARLY PHONOLOGICAL ERRORS
consonant clusters
reduced to smaller units
e.g. pider for spider
EARLY PHONOLOGICAL ERRORS
substitution
substituting one sounds for another
e.g. pip for ship
EARLY PHONOLOGICAL ERRORS
reduplication
repeating a whole syllable
e.g. dada, mama
BERKO AND BROWN
1960s
looked at phonological errors to see how they link to understanding of words and ideas and ability to link lang
a child referring to fish as fis couldnt link adult use of fis with same object
child recognises correct pronunciation but cannot manage to pronounce it themselves
GRUNWELL
1981
research on phonological devel. of children and order in which they developed diff sounds
MAMA VS DADA
roman jakobson
‘m’ sound easier to make because tend to do so when mouth fastened to bottle/ breast
MAMA VS DADA
breyne moskowitz
nasal sound ‘m’ more difficult
dada easier
FIRST WORDS
katherine nelson
1973
4categories
naming
actions/ events
describing/ modifying
personal/ social words
60% nouns
THEREFORE early vocab contains content words and function words come later
OVEREXTENSION
common for children
link objects with similar qualities e.g. ‘dog’ for all 4-legged animals
word stretched to include things that aren’t usually part of word meaning
CATEGORICAL overextension
name for one member of a category is extended to all members of the category
e.g. apple for all round fruit
ANALOGICAL overextension
a word for one object is extended to one in a different category
usually on basis it has some physical or functional connection
e.g. ball used for a round fruit
MISMATCH STATEMENTS
one word sentences that appear quite abstract
UNDEREXTENSION
word used to label is reduced to only part of the meaning
e.g. white may refer to snow but not socks
JEAN AITCHISON
connects lexical and semantic development in stages
LABELLING - linking words to onjects to which they refer, understanding that things can be labelled
PACKAGING - exploring labels and to what they apply, using under/ overextension to understand the range of a words meaning
NETWORK BUILDING - making connections between words, understanding similarities and opposite meanings
use hypernyms = general word: clothes
using hyponyms = more specific words within categories: socks, shoes
HALLIDAY
7 FUNCTIONS OF CHILD LANG 1978
INSTRUMENTAL - used to fulfill a need, such as to obtain food, drink or comfort e.g. concrete nouns
REGULATORY - used to influence behaviour of others without persuading, commanding or requesting
INTERACTIONAL - used to develop relationships and ease interaction e.g. ‘i love you mummy’
PERSONAL - express personal opinions, attitudes and feelings including identity
REPRESENTATIONAL/ INFORMATIVE - used to relay or request info
HEURISTIC - used to explore, learn, discover with qs or running commentary
IMAGINATIVE - used to tell stories and create imaginary constructs, accompanies play
behaviourist approach
skinner
pos/ neg reinforcement
pav dogs
environment
relies on others
nativist approach
innate lang learning
chomsky
biological - in nature to learn lang
restricted by other factors
LAD - language acquisition device
poverty of stimulus
cognitive
Piaget
must understand lang before can use it
social and ego-centric speech
social approach
bruner
shared reading experiment
lang as a result of socialisation
interaction
external model e.g. parents
POVERTY OF STIMULUS
critical period for lang learning
BOSTON UNIS
proficient at learning lang until 18
near impossible to learn native level fluency after 10
CHALLENGES:
lack of knowledge surrounding brain
hard to monitor
generalisation
ethics
GENIE
put in basement and never spoken to/ allowed to speak
when was rescued, never fully grasped lang and stayed in early stages of lang for whole life
CATHERINE SNOW
1972
compared how mothers speak to 2 vs 10 y/o
simpler and more exaggerated
concrete nouns
MARK VANDAM
2015
female caregivers more likely to use supportive lang and melodic intonation
male cregviers often present more challenging forms of vocab
M similar to talking to adults - less sing song and less simplifying
SCHLIEFFEN AND OCHS
CDS makes CLA easier for infants
HOWEVER:
others studies look at Kaluli tribe who dont speak to children differently, yet develop lang the same
underestimation of how much lang learning comes from listening to other adults conversing with each other rather than through direct interaction with adults
VIRTUOUS ERROR
grammatical error made by young children in which the non-standard utterance reveals some understanding, though incomplete, of standard grammar
OVERGENERALISATION
learners extension of a grammatical rule beyond its normal use
past tense -ed
plural -s inflection
JEAN BERKO
1950s
study into pronunciation and morphological development
-s plural
WUG - asked for plural
¾ said ‘wugs’
INTERNALISATION
heard a rule so often that it was second nature to apply to make a plural
WATSON AND RAYNER
1920s
Albert 9-12 months
showed range of animals
white rat - loud sounds
developed phobia of rats
SKINNER
1957
beyond classical conditioning to operant conditioning
P/N REINFORCEMENT
P- praise when say something so continue to act that way to receive more praise
N - corrected so don’t make mistake again
learn through imitation and observation, with reinforcement from parents
CHALLENGES TO SKINNER
CHOMSKY disagreed
theory not secure in showing how children acquire language
impossible to have heard every sentence needed whilst talking, which is the idea that Skinner essentially introduces as children learn and imitate
e.g. sentence ‘colourless green ideas sleep furiously’ grammatically but semantically does not make sense
