Lecture 6: Language Flashcards
Language definition
the systemic, meaningful arrangement of symbols
Parts of language
- Phonology
- Phonemes
- Morphemes
- Semantics
- Linguistic comprehension
- Linguistic production
Phonology definition
basic sounds of language
Phonemes definition
can be combined to produce words and sentences
Morphemes definition
smallest language unit that has meaning
Semantics definition
rules that govern meaning of words and sentences
Linguistic comprehension definition
understand speech
Linguistic production definition
use of language to communicate
How do you acquire language?
- Unspecialized brain
- Proto-understanding of probability
- Human interaction
Acquire language facts
- Lack of brain + brain be specialized to enviro.
- Language made of words
- Neural pathways used more often get reinforced, ones not used are terminated or repurposed
Statistical probability definition and fact
Definition: uses string of syllables, and phonemes always follow another
Fact: Habituate an infant, the change it, infants will notice change
Learning theory and language acquisition facts
- Cause by classical and operant conditioning
- Pairing of stimuli to point where response to first 2. stimuli will also be produced by second stimulus alone
- caregivers respond to infants’ utterance and reinforce verbal behaviours (verbal praise)
Who was the founder of Nativist Theory and Language Acquisition?
Noam Chomsky
Poverty of stimulus argument
- Children are not exposed to every grammatical rule to learn language
- Children are able to construct sentences that they’ve never been exposed to previously
Language acquisition device (LAD) definition and facts
Definition: Innate facilitator of language
- Permits infants to learn fast and efficient
- Analyze everyday speech and determine its rules
Universal grammar definition
LAD innate storehouse
Fact: Language does not emerge in a finished form or occur as quickly and requires more effort on part of children
Interactionist Perspective + Language acquisition process
- Language development is complex influenced by maturation and context
- People have innate needs for communication
- Responsiveness to infants’ vocalization predicts language development
- Infant-directed speech (baby talk but more tolerable)
Critical Period definition and fact
- limited time span when development is optimal for certain capacities to emerge, especially responsive to certain exp.
1. Young infants/children are ideal in learning a language
Pre-linguistic communication stages
- At birth — infants cry
- 2-3 months — infants coo
- 6 months — infants babble
Socially interactive process definition
Babies learn by hearing others speak and reactions of others
First word stages
- 1yr, infant speaks first word
- Holophrase
- 13 months of age
Holophrase definition
one-word expressions
What do infants do at 13 months of age?
infants begin to quickly learn meaning of new word
Learning words stages
- Fast mapping
- Name explosion
- Under-extension
- Overextension
Fast mapping definition
process of quickly acquiring and retaining a word after hearing it applied
Name explosion definiton
vocab spurt
Under-extension definition
using words to narrowly, so word is used more restricted to single object
Overextension definition
applying word too broadly
Two-word utterances
A) Telegraphic speech
B) 20-30 months children showing competence using syntax
Interactionist perspective + language (further expanded)
- Expansion
- Recast
- Cultural shapes in language
Expansion
Enriched versions of child’s statement
(Want cookie —> i want cookie)
Recast
Adults change children’s sentences into new grammatical forms
(Juice please —> i would like some juice, please)
Cultural shapes in language
- Parents from diff. Cultures differ in how and how often respond to infants
- Points to biology and context
Vocab: early childhood
A) 2yrs = 500 words
B) 3yrs = 900-1000 words
C) 6yrs = 2,600 words, understand 20,000
Logical extension
Extend new words to other objects in same category
Mutually exclusivity assumption
Tend to assume that new words are labels for unfamiliar objects
