communication and language dev. Flashcards
language comprehension and production
comprehension: understanding what is said
production: spelling
infants exposed before birth
study babies in womb
mother read 3 stories *2 a day for 6w -> after birth, showed a preference for previously exposed stories (increased sucking frequency)
phonemes
basic unit of sound used to produce language. smallest unit of sound that affect meaning
1 and 4 months : demonstrate categorical perception of phoneneme
1-2 : respond to phonemes of all languages
6m: greater sensitivity to phoneme from own language
12m: less ability to distinguish phonemes from non-native language
ability to distinguish speech sounds-> later language dev.
7m: distingıish between language
2 y: distinguish between vocab
word segmentation
7m: preference for words previously heard in sentence string to novel word
universality of babbling
infant from diff culture babble same of the same consonant-vowel combination
specific language by 8-10 m
deaf infants babble verbally
-> babble non sense sign language
babbling predicts later language dev.
when babbling not present by 10 m -> late dev. delay
joint attention
-> making sense of what is being communicated
increased ability to follow attention3-18m
direct attention (checking back, pointing )
intersubjectivity
mutual understanding that people share during communication
turn taking
turn-taking in language from early age, influence infant vocalisation
adult responsiveness
maternal responsiveness predicted child vocab at 20 m
morphenes
semantic dev. learning about meaning infants recognize>begin to comprehend words> produce 6m: recognize body part and food words 10 m: understand 150 words 12-18 m: first spoken word
first word: labelling objects and people (universal)
first sentence: 24m vocab dev. w age: 6y: 10.000w
11y: 40.000w
college level: 150.000w
common errors
overextension: using same word for many things
under extension: using a word in restricted and individualistic way
syntaxing
rules of combining words first sentence: two word utterance 2 1/2 y: complete sentence grammar: rules to combine our set of words plural - s ;past tense -ed -> essential to language dev.
pragmatic
learning how language is used
2 y: respond to feedback from listeners: repeat message in no response
3-4 y: turn taking, eye contact and respond appropriately
critical period for language
-sensitive periods: period in dev. during which an organism is most sensitive to effects of external factors
critical periods: limited period of dev. during which organism requires certain condition in order to grow and mature
5y and puberty for language
second language
12 m restricted to own language
second language before 7 y-> nattive language
learning later -> poor grammar recognition
indv diff: can learn language after puberty
parental influences
parental scaffolding: repeating and building child’s words
aid language dev
labeling object + card games= help w social reference problem
link social class and words hearing to child vocab relationship between environment and language dev.
