phonological and lexical development Flashcards
hockett’s design features of language
- arbitrariness: no necessary connection between sounds used + message sent
- displacement: communicating about things that aren’t present
- productivity: create new utterances from previously existing sounds
- duality of patterning: meaningless phonemes combined to make meaningful words + sentences
what side of the brain do we process speech on?
left
categorical perception of speech sounds
-happens at 1 month: /p/ and /b/ - suck more when notice difference
phonemes
=smallest segmental units of sound to form meaningful contrasts between words
conditioned head turning paradigm
- tests auditory thresholds
- baby turns head when hears different phoneme, foreign exposure can maintain this ability
gaze following
-happens at 18 months
pointing
- happens at 9-14 months
- imperative: tell someone to do something
- declarative: inform
- interrogatively: request info
- index finger pointing –> predicts vocab learning
language forms
- phonological forms (sounds)
- word forms (lexical/vocab)
- grammatical forms (syntactic and morphological)
- prosodic forms (rise and fall intonation)
language functions
- semantic functions (how forms used in relation to the world)
- pragmatic functions (how language forms are used in relation to context)

- perlocutionary stage: child has unknowingly effect on listener
- illocutinary stage: child intentionally uses non-verbal signals to convey requests
- locutionary stage: verbal utterances
when do coordinations of vocalisations/gestures and gaze happen?
11 months
age that we form words, sentences?
1 year- words
2 years- sentences
-age 6: 10-14,000 words in lexicon
gavagai problem
we need constraints on word learning so that they don’t run into problem of determining which meaning a word is used to convey
- association: child thinks word refers to whatever salient object their attention has been brought to
- mutual exclusivity: tendency to assign label and avoid second label
- syntactic bootstrapping: linguistic context can help us guess meanings of words
- social pragmatic theory: children learn words easily bc their world is routine
- intention reading: learn words by figuring out what someone is trying to communicate
