Language and literacy studies Flashcards
Werker and Hensch 2015
Critical periods, week 1
- lifetime plasticity
- but timing of attunement maybe under maturational control (gestational not birth age) suggesting opening of CP
- ‘infants have perceptual biases, learning mechanisms and neural systems that orient them to language’
- this provides initial foundation for categorisation, become attuned to properties of native language
- molecular brakes provide stability - if can identify and remove, reopen plasticity
- mental illnesses including language impairments (schizophrenia, autism) share defects in triggers and brakes regulating CP timing
Pinker 2007
‘the most remarkable thing we do with language is learn it in the first place’
Sociolinguistics and bilingualism, Whitehead 1990
Must not pressure into using only English
- need A language for thinking, planning, social interactions, cognitive development
- undermines self-esteem and confidence if don’t see representation of first language
- beware of presenting ‘other’ language in disrespectful context - the power and influence of language, dialect and accent
- consider multilingualism (very common!) as an asset - increased linguistic awareness, cultural sensitivity, cognitive functioning
Coltheart et al 2001
Dual-route cascaded model of reading and writing
Key players in behaviourism/cognitive/nativist
Skinner - 50s-60s
Piaget - 30s
Chomsky - 60s
Fenson et al 1993
Measure of vocabulary size
Created the MacArthur-Bates Communicative Development Inventory
- identifies critical mass of words, word explosion
Brooks and Kempe 2012, how infants discover words
- prosodic and phonological cues, rhythmic properties of language
- distributional information - statistical probabilities with regularly heard syllable combinations learned faster, and words heard in isolation learned faster (eg own name)
- should be really hard to learn words! phonemes rarely heard in isolation but in words in streams of speech
Kuhl et al 2008
Better sensitivities to native vs non-native contrasts at 6-12 months predictive of better language learning outcomes at 2-3 years
- sensitivity to non-native contrasts not good
- tune into native language instead
Werker and Tees 1984
6-8 month olds from English homes can distinguish non-native contrasts
10-12 month olds cannot
Mehler 1988
Newborns can distinguish native vs non-native languages, and have preference for native
- learn the phonotactic foundations - which sounds ‘legal’ in your language
Pinker 1994
Foetuses in utero can process sounds, and learn prosodic properties and melody of native language
- distinguish language vs noise
- distinguish mother vs non-mother
Sheridan 1997 (normal development of language needs)
Needs:
- play
- attention and listening
- understanding of language
- expression of language
- intelligibility
- pragmatics
Abreu et al 2014
Bilingualism may be protective against the cognitive limitations present in SLI in monolinguals
Lees and Urwin 1992
Delay
- child should catch up
Disorder
- persistent deficit, with mismatch between language and other skills
- suggested by eg order mistakes, or vowels affected in intelligibility
- receptive, expressive, or mixed disorders
Bishop 2006
Causes of SLI in children
(7%ish prevalence, depending on criteria and age thresholds)
- Genes - tends to run in families, MZ twins more than DZ twins. Commonly one MZ twin will meet diagnostic criteria, other twin will not but still evidence of language difficulties - categorising as SLI/not is not useful.
- no one gene for language
- not simple inheritance
Bishop 2002
Heritability estimates of SLI 0.5-0.75
Fisher 2005
One gene for SLI? NO
FOXP2 is regulatory gene of other genes, affects development of many organs inc brain systems for speech and language
Graves 2003
Environmental factors in SLI
- mother’s educational level
- nutrition
- varied types of language interaction and socialisation
Taylor and Taylor 1990, word acquisition
Pragmatic factors affecting word acquisition
- simple short words before long complex
- gross before subtle distinctions
- most obvious things first
- personal before non-personal
- here and now before that which is dispersed in time and space
- concrete before abstract
- frequent and familiar first
- regular before irregular forms
- items in isolation before relationships
Harley 2014, early categorisation
Over/undergeneralisation
- a result of restricted understanding/perception, or a result of restricted vocabulary
Harley 2014, un-taught generalisations
Children able to complete:
‘This is a wug. Now there are two, there are two _.’
- can do this from very young age
- though clearly never taught the word ‘wugs’
Bialystok and Hakuta 1994
Types of bilingualism - simultaneous, early sequential, late sequential
Willet 1995
Languaculture
- language and culture inseperable, must consider together
- language of instruction matters
Drury 2000
Case study of Samia
- early developmental stages of learning English
- unable to successfully interact with peers, though more confidence with adults (importance of one-to-one interaction)
- Samia’s attempts at English not responded to by peers
- rehearses at home ‘school game’ with younger brother (code-switching to keep him engaged), and doll play
- uses more complicated and experimental language when alone
Tabors 1997
Double bind
- communicative competence and social competence
- each is necessary for the development of the other
Sharpe 1992
Keys for successful language:
- communication
- culture
- confidence
- context
Immersive language techniques
- Bruck et al 1976 - Montreal study of English-speaking children taught exclusively in French from day one. Found very beneficial to language learning, and all areas of development including eg maths.
(may be overwhelming all at once)
Harley 2014, why is learning a second language difficult?
- outside of critical periods (syntax and phonemic differences)
- less time and motivation once already have L1
- varying difficulty depending on how closely related the languages are
Harley 2014, organisation of bilingual language system
Separate stores model
- separate lexicons, phonemic stores, syntactic processing
- Kirsner et al 1984
Common store model
- one lexicon, one semantic memory system
- semantic priming to facilitate between languages
- Altarriba 1992
Kirsner et al 1984
Evidence for separate stores model of bilingualism
- repetition priming (facilitation gained by repeating a word) has greater and longer lasting effects within than between languages
Altarriba 1992
Evidence for same store model of bilingualism
- equivalent words share an underlying semantic representation to moderate priming between words
