CLA Flashcards
Holophrastic stage
-12-18 months
- earliest recognisable language
- one word can convey a complete idea or a large amount of meaning
- non verbal contextual clues are very important
Holophrastic stage - key research
- Bloom (2004)
- noun bias (60% of infant early words are nouns) in early children’s vocabulary merely reflects the relative frequency of nouns in the vocabulary
Holophrastic stage - pre verbal development - key research
- Jean Aitchson (1997)
- At about 18 months, a child will realise that every object, person or place has a word/label attached to it and therefore will develop a ‘naming insight’ (awareness and children making grammatical connections)
- followed by ‘naming explosion’ when children develop new vocabulary in order to fill the gaps in their lexical knowledge
Two word stage (18-24 months)
- vocab explosion
Behaviourist approach
- Developed by Skinner
- “Behaviour is shaped and maintained by its consequences”
- children acquire language by imitating the speech of others and being rewarded for it.
- when a child produces the words correctly, they’re praised through rewards.
-if we doing something and it has good consequences, then we will do it again
Behaviourist approach support - operant conditioning
- method of learning that uses rewards and punishments to modify behaviour.
- children copy words they’ve heard a parent say
- they adopt that similar pronunciation
- they adopt pragmatic features like politeness and colloquialisms from parents.
Behaviourist approach criticisms - Brown, Caazden and Bellugi
- caregivers don’t correct language but use truthfulness
- even if a child says something grammatically wrong but truthful, the caregiver will still give praise.
- if the child says something grammatically accurate but untrue, the caregiver will respond negatively.
- truth is more important than langauge accuracy
- skinner is unaware that language use isn’t often corrected
- therefore the behaviourist approach isn’t the most effective approach for CLA
Behaviourist approach criticism - Jean Berko
-children figured out the final sentence that read “there are two wugs” even though they’ve never heard “wugs” so there was no evidence on imitation
-wug Test suggests that children can accurately apply linguistic rules that they have not heard or used before - so they haven’t been able to copy anyone
- children can’t hear things frequently enough to copy it.
- they learn grammatical rules like adding “s” to form plurals or “ed” to form a past tense this can be know as development milestones.
Behaviourist approach support - things to look for in data
- adults explicitly modelling or teaching language and children responding
- children imitating/repeating adults speech
- children learning or repairing mistakes after correction from adults
Behaviourist approach refuting- things to look for in data
- children using speech they haven’t copied
- children using non-standard language when adults use it in its standard ways
Behaviourist approach criticisms - Chomsky
- language used by adults when specking to children is “impoverished”.
- we speak to them in a deficient way, not in formal standard English.
- children would never learn to be adult speakers if they could only copy what adults said to them.
Behaviourist approach criticisms- Berko and Browns Fis Phenomenon
- adult: this is your fis. Child: no- my fis. adult : oh your fish . Child: yes my fis
- child can’t produce the phoneme (sh) but knows it’s different from the phoneme (s)
- therefore the child can’t copy it even though he knows it.
Nativism
- developed by Chomsky
- the idea that children have an inbuilt ability to understand grammar
- due to our a language acquisition device (LAD) in our brain which activates their linguistic development .
- LAD enables children to listen to language being used and extract the rules of grammar from it.
- the LAD also proposes that linguistic development in children is a natural process
Nativism - universal grammar theory
- all languages share a deep structure (nouns and verbs)
- children are born with this knowledge
- this is why children are able to develop language proficiency so rapidly
-due to the language the child hears in daily life
Nativism - virtuous error
- supports LAD
- mistakes child makes because it has learned the grammatical rules of English rather than exceptions
- shows child is attempting to apply rules they’ve figured out
- e.g ‘I swimmed’ shows that child has learned the ’ed’ past tense rule but doesn’t know that ‘swim’ is a strong verb
Nativism support - LAD
- explains the rapid speed with which children acquire language
- the fact that all children acquire language in the same stages
- how children can use and understand new sentences
- the LAD will often resist corrections to their mistakes as the LAD is instructing them that their way of using language is correct and that the caregiver is wrong
Nativism support - Isaac Slobin
- claims human autonomy is specifically adapted for speech
Nativism criticisms - grammar
- sentences can be grammatically correct but still semantically meaningless.
- learning grammar isn’t the same as using language
