Language Development Flashcards
Continuity hypothesis
Babbling foundation of language - start producing all sounds and learn which are relevant from reinforcement from parents
John Locke on language
-common sense view of language - words used for recording thoughts and communicating our thoughts to others
Discontinuity hypothesis
Babbling has no relationship to language
Overregularizarion
Over generalize grammatical rules to irregular cases
Syntax
Rules, word order, structure that underlie meaningful utterances
Phones
Speech sounds
Phonemes
Speech sounds that are meaningful in a particular language
Categorical perception
Adults perceive speech sounds in categories
Infant directed speech
"Motherese" Short simply syntax Many questions and commands Simply words High redundancy and repitition High pitch and variability in speech
Word boundary problems
Seeing perceived breaks
Some words have other embedded words
Meaningful melodies - 4 types of mother infant interactions:
- attention (to new toy)
- approval (praise infant)
- prohibition (tries to stop infant fro, touching)
- comfort (mother soothing infant)
Infants respond pos or neg to approvals or prohibitions even in unfamiliar languages
Constraints approach to word learning
Word learning biases beginning at 18 months - constraints to deal with indeterminacy problem - what does it mean part, whole - helps them figure this out
- whole object assumption, mutually exclusivity assumption and taxonomic assumption
While object assumption
A new label is a likely to refer to the whole object not its parts
Mutually exclusivity assumption
Each object only has one label - prevents redundant guessing
Taxonomic assumption
A novel label refers to objects of the same kind not objects that are thematically related
Problems with constraints
- Are they in place for early word learning or are they a developmental outcome
- children must overcome them to learn many words
- they only apply to object labels
- must be used in conjunction with social pragmatic cues to figure out intent
Two views of language
1) code model of language - constraints - yes but doesn’t get on everything
2) language as activity - social pragmatic approach - how words used
Social pragmatic approach
Social nature of words- word learning based on what is Most relevant in that situation
- part of activity -lots of cues to figure out language
- what does the speaker want the listener to attend to - importance of joint attention
Syntactic bootstrapping
Use of syntax to infer word meaning
- see if verb, count noun or mass noun
- if not enough info children use their general knowledge
