Lexical development Flashcards
Naom Chomsky
- Nativism
- we are predisposed to acquire language
- we have a Language Acquisition Device (LAD)
- this is the reason there is a global capacity of children to learn language at the same rate = Universal Grammar
- reason for virtuous errors (runned, sheeps): children make their own language through their own logic rather than what they have observed entirely through adults
Stephen Pinker
- Nativism
- developed on Chomsky’s theory
- furthers the theory saying language acquisition is a human instinct and we have a natural urge to learn, rather than a biological switch in our brain
- lang develops in a child spontaneously without effort / instruction
- babbling = practicing
- suggests language is caused by dedicated circuitry that evolves In the human brain (mother board of connections)
Criticisms of Nativism
- undermines role and influence of care givers
- critical period hypothesis: abused children often don’t fully develop syntax and grammar, children must be exposed to language by a certain age (Genie case)
Tomasello
- cognitive-linguistic approach
- rejected Chomsky’s Universal Grammar
- we have a need to cooperate and communicate
- not a biological thing, just a desire to be social
- e.g. we learn to do things like run because we want to experience it
- acknowledges the importance of caregivers and ranges of contexts
Jean Piaget: Constructivism
- Constructivism
- Early Tomasello
- comes from the desire to communicate
Jean Piaget: Constructivism Stages
Sensorimotor stage:
- 0-2 years
- egocentric
- some awareness of object permanence
Pre-operational stage:
- 2-6/7 years
- most important to what might be on the transcript in exam!!
- become capable of representing the word symbolically
- child remains egocentric
- begin to question more
Concrete operational:
- 6/7-11/12 years
- stops being as egocentric
- can notice patterns more
Lee Vygotsky
- social constructivism
- children are active in the creation of their own knowledge
- focused on role of caregiver
- zone of proximal development: the area between what a child can do and what is beyond their reach, where a caregiver offers support to facilitate learning
Lee Vygotsky: constructivism Stages
Primitive speech stage:
- 0-2 years
- begins to learn to speak through imitation
- responds emotionally and socially (laughing and crying)
Naive psychological stage:
- 2-4 years
- realize words are symbols for objects: curious
Egocentric speech stage:
- 4-7 years
- talk aloud to themselves as they do tasks / solve problems (private speech)
In-growth speech stage:
- 8+ years
- private speech declines and becomes more internalised (inner speech)
Jerome Bruner
- Interactionism
- rejected Chomsky’s LAD
- focused on the importance of caregivers
- suggested Language Acquisition Support System (LASS)
- caregivers provide opportunities for children to acquire
- focused on child-directed (CDS) speech and scaffolding (support provided by caregivers through modelling how speech ought to take place
CDS: Expansion
where the caregiver elaborates on an utterance given by the child
CDS: Recasts
where the caregiver repeats a child’s utterance but corrects it slightly
CDS: mitigated response
- where a command is given but disguised in the form of a question
CDS:diminutives
doggie, mummy, horsie
other features of CDS:
- high / melodic pitch
- more frequent / longer pauses
- slower clearer speech
- repetition
- more questions
- using nouns rather than pronouns
Catherine Snow, 1970
- Parentese
- describes the way parents adapt their speech when interacting with children
Stage 1: pre-birth stage
- even before born the baby will recognize mother’s voice
Stage 2: pre-verbal stage
- vegetative / crying: 0-4 months
- cooing: 2-6 months
- babbling: 6-12 months
- proto-words (word-like vocalisations): 9-12 months
Reduplicated babbling
- simpler
- appears first
- child repeats sounds
- bababababa
Variegated babbling
- slightly later
- involves variation in the consonant and vowel sounds
- e.g. daba, manamoo
Stage 3: Holophrastic stage
- 12-18 months
- begin to utter first complete words
- use one word in substitution to an entire sentence
- usually concrete nouns
- rely on paralinguistic features (facial expressions, gestures, noises)
- gestalt expressions: allgone, wassat?
Stage 4: Two-word stage
- 18 months
- two words together
- e.g. mummy sit
- non-verbal communication decreases
- begin understanding grammar
- Pivot schema (Braine 1963)
Braine, 1963: Pivot Schema
- at two-word stage, they use patterns of two word utterances that revolve around pivot words
- pivot words (high frequency) combined with slots (low frequency) to create meaning
- ‘allgone’ = ‘allgone doggy’, ‘allgone dinner’, ‘allgone daddy’
Stage 5: telegraphic stage
- around 2 years
- similar ot telegram
- longer than two words but includes only big key content words
- lack of articles or prepositions
- e.g. ‘me go park’
Stage 6: post-telegraphic stage
- 3-4 years
- becomes similar to adult speech
Lexical development
- learn 10 new words a day
- 18 months: 50 word vocab
- 24 months: 200 word vocab
- 36 months: 2,000 word vocab
Katherine Nelson, 1973
- placed children’s early words into four catagories:
- naming
- action
- social
- modifying
- found largest catagory was naming words
- 60% of a childs first 50 words were nouns
