Q

SYMBOLIC RULE-GOVERNED SYSTEM

A
  • abstract/productive
  • enable speakers to produce/comprehend wide range of utterances
  • parts of language represent meaning (ie. “ed” suffix implies past tense)
  • “bird” = arbitrary BUT refers to avian creatures
  • each language is constrained by unique rules

Q

PRODUCTIVE

A
  • finite units (sounds/words) produce infinite utterances

- not all possibilities are useful; some are abstract/hypotheticals (ie. “why does the amused jelly win the iron?”)

A
  • cognitive/social skills enabling effective communication (ie. turn taking/convo initiation/dialogue maintenance/faulty communication repair)
  • essential: ie. DO TAKE A SEAT
    LITERAL M: Take a chair somewhere.
    LITERAL R: Remove chair.
    PRAG M: Please sit down.
    PRAG R: Sit on the indicated chair.

Q

PHONOLOGY & MORPHOLOGY

A
  • speech sounds/combinations to words/utterances
  • basic units:
    MORPHEME (MEANING) = language
    PHONEME (NON-MEANING)
  • speech (“ba” “ba” = habituation; “pa” = attention)
  • 1m babies discriminate; 12m discriminate own language but not others (become native listener)
  • adults struggle
  • babies cannot tell difference between “ba” & “ba”

  • higher/exaggerated pitch
  • rhythmic/slower
  • short, perfectly grammatical sentences
  • concrete NOT abstract
  • here/now; running commentary for the present

Q

5 STAGES OF BABBLING

A
  1. 0-2M
    - reflexive vocalisations (ie. crying/sneezing/burping)
    - directly related to physical state
  2. 2-4M
    - cooing/laughing
    - combining sounds
    - happy state
    - reciprocal w/parent
  3. 6-10M
    - canonical babbling
    - combos sound like words
    - no evidenced meaning
    - uniformity of age period/range of sounds (ROTHENGANGER (2003))
    - deaf/hearing kids of deaf parents babble
  4. +10M
    - modulated babbling
    - final period overlapping meaningful speech

Q

LC: SYNTAX

A
  • the way words are put together for meaningful utterances
  • in English, word order = important grammatical component
  • acquisition follows predictable pattern (10-18M = first words)

Q

THE 1-WORD STAGE

Study These Flashcards
A
  • 10-18M
  • holophrastic/syncretic speech period
  • thoughts represented via one word
  • ie. “doggie” = “I want my dog”
18
Q

CULTURAL SYNTAX DIFFERENCES (EXAMPLES)

Study These Flashcards
A

TARDIF et al (2008)
- early words:
ENGLISH = people based; object nouns; animals/sounds
CANTONESE = people based; verbs; rare animals

19
Q

THE 2-WORD STAGE

Study These Flashcards
A
  • 18-24M
  • non-random pairs (ie. “kick” ball)
  • salient/high-meaning; verbs/adjectives
  • mixed order regardless of reality (ie. “lick doggie” = “doggie lick”)
20
Q

CHARACTERISTICS OF EARLY SPEECH

Study These Flashcards
A
  • telegraphic speech = semantically rich but grammatically sparse
  • named by ROGER BROWN; early child language investigator
  • utterances express essential meaning but ignore unnecessary grammar; compared to texting?
21
Q

24-36M: WHAT’S DEVELOPED?

Study These Flashcards
A
  • utterances = longer/more complex
  • use of verb endings (ie. “ed” signifying past)
  • model auxiliary (“will”)
  • conjunctions (“and”/”so”)
22
Q

OVERREGULARISATION ERRORS

Study These Flashcards
A 
PAST TENSE 
- "thinked" not thought
- "goed" not went
PLURAL 
- "mans"/"mouses"
23
Q

CREATIVE OVERGENERALISATIONS

Study These Flashcards
A
  • nouns = verbs (ie. “why is it weathering?”)

- used w/novel words; follow known rules strictly

24
Q

SEMANTICS

Study These Flashcards
A
  • words/aspects of them represent meanings

- these units are symbolic as they refer to things other than themselves

25
COMPREHENSION
- meaning is attached to words early on TICOFF & JUSZCZYK (1999) - 6ms given video of parents; looked more at correct parent depending on word heard (ie. "mummy" = mother)
26
SEMANTIC ERRORS
KUCZAJ (2003) - due to huge possible interpretations that children may make of a word's meaning, it's unsurprising that some initial guesses are incorrect - can be: OVEREXTENSION = bird/plane/kites/falling leaves UNDEREXTENTION = ONLY rubber ducks, no others
27
VOCAB DEVELOPMENT SPEED
- kids construct vocab of 14k words by 6y despite its complexity, meaning aprox. 9 words p/d
28
SEMANTIC CONSTRAINT
- whole object constraint - "elephant" = whole animal, not parts - mutual exclusivity; nothing else is an elephant/elephant is not known as anything else
29
FOUR THEORETICAL STANCES
BARRETT (1999) - NATIVISIM (NATURE) - innateness hypothesis - innate info processing dispositions - EMPIRICISIM (NURTURE) - learned language - develops much as other cognitive abilities do
30
NATIVISIM (NATURE)
MARATOS (1999) - product of evolution/natural selection and pure endogenous processes internal to organism - species-specific; universal in humans - inherited from parents; present in newborns - results from genome/typical species environment interaction
31
NATIVIST 1
- some aspects of development are dependent on innate capacities/knowledge (ie. CHOMSKY/PINKER) - most extreme nativism; info processing skills specific to language acquisition and knowledge of language aspects are generational via genes
32
NATIVIST 2
- language development is strongly influenced by innate info processing dispositions (KUCZAJ) BUT doesn't assume birth w/innate language knowledge (ie. innate discrimination of phenomes specific to learned language) - rather, a number of innate processing dispositions/abilities (also applicable for non-linguistic development) = important to acquisition
33
EMPIRICISM (NURTURE)
1. language experience is vital | 2. development via experience in similar cognitive ability fashion; nothing special about language
34
EMPIRICIAL 1
- children acquire language specific concepts/representations due to language experience rather than innate specification
35
EMPIRICAL 2
- children acquire language due to general abilities that play role in general cognitive development (ie. ToM) CHOMSKY - universal grammar; s/d structures - language needs to relate s/d structures - environment = only s, so d = innate - kids hear complex/ungrammatical sentences (poverty of stimulus/Plato's problem) w/little grammatical feedback yet acquisition is quick/easy
36
NATIVISM: +
- phonemic discrimination - over-regularisations - creative over-regularisations - applied rules
37
MODI EXPERIMENT
AKHTAR, CARPENTER & TOMASELLO (1996) - objects given to kids but not named; experimenter leaves; objects in box and one added; experimenter returns and acts excited about a "modi" - when asked to hand over the modi, kids are more likely to give the new item - kids guess people's intentions to understand the meaning of a new word; you need a ToM
38
MODI EXPERIMENT (EXPLAINED)
- in order to see new item = modi, kids must know: - the experimenter was referring to it - people get excited about new things - modi = new item despite none of the other items being named - OVERALL, guess experimenter's intentions
39
META-ANALYSIS OF HERITABILITY ESTIMATES
ANDREOLA et al (2020) - focussed on neurocognitive components: general reading (comprehension); letter-word knowledge; rapid automatized naming; phonological decoding/awareness; spelling/language - 49 articles; 23 cohorts; 38, 670 pps; 15, 990 MZ; 22, 680 DZ; 4.1y-18.5y - genetic/non-shared environmental factors explained most variance in domains
40
THE TWIN MODEL
- MZ/DZ twins used; difs used to parse phenotypic trait variance into genetic/environmental components - genetic influences implied if MZ correlation > DZ
41
META-ANALYSIS OF PARENTING/LANGUAGE DEVELOPMENT
MADIGAN et al (2019) - does sensitive-responsive parenting/warmth affect child language? - 32 studies; sample size 9-1026; median = 142; 33.5m (range = 12-71m); mean boys = 51.1% - parental warmth/sensitive responsiveness to child language association = STATSIG - language development is fundamental for school readiness/comprehension/academic achievement/occupational outcomes - parental behaviour influences child language development; modifiable factor targeted for interventions - limits = observational only, so findings = correlational only; needs controls (RCTs)
