Thought and Language Flashcards
hierarchical order of language
phoneme, morpheme, word, phrase, sentence
phoneme
single unit of sound that changes meaning (eg dog vs log)
not all languages have the same phoenemes
morphemes
the smallest language units that carry meaning (words, suffixes, prefixes)
one morphene (dog) two morphenes (dogs)
content words
words that have meaning
semantic processing relies on processing content words
- nouns (dog, book, student)
- verbs (walk, swim, sleep, teach)
- adjectives - modifty nouns (warm, beautiful, good, kind)
- adverbs - modify verbs (well, poorly)
function words
Conjunctions and most pronouns
syntactic processing relies on processing function words
pronouns(she, he it, we, they)
prepositions (in, of, on, out, at, by)
conjunctives (and, but, or)
words such as that, this, a, the, if, to
brocas aphasia
language relevant brain areas: right handed people: left hemisphere, mostly lower edge of frontal lobe and upper edge of temporal lobe
brocas area: located near areas that control speech muscles
syntax
- refers to structure of language
- rules for ordering words
syntax is cued by word order
- subject - object - verb: jane the apple ate
- subject - verb - object: jane ate the apple
- verb - subject - object: ate jane the apple
wernickes aphasia
aphasia: the inability to produce or understand language
wernickes area: left temporal lobe- next to primary auditory cortex - translates sounds into meaning
english syntactic word order
- subject, verb, object
infants set of sounds
cooing
- 2 months
- relying on social cues (eye contact) which develops their language
reduplicated babbling
- 6-7 months - some syllable over and over
- babbling where they are starting to form words
varlegated babbling
- 11-12 months syllables with different consonants and vowels
- 10 months children can categorise sounds into meaningful and not
- babys sounds have adpated to language it hears, adults can tell what language baby is learning
infants limited set of sounds
- Anatamony of a young baby compared to a adult
- Lips and gums – little room in a babys mouth – produced much more foward
- As the primary use of mouths for babies is sucking
- This is why sounds like mm, pp, dd are produced first because that’s where the tongue and lips are devloping or being used the most
- Vocal cords are much closer in a baby that adult so they use a lot more of those voiced sounds than the unvoiced sounds
At the age of 3 start to produce those harder sounds
vocabulary burst
major increase in productive vocabulary acquistion rate after first 50 words are learned
why?
- symbolic nature of language
- control over articulation
- easier retrieval
overextension and underextension of meaning
underextension
- dog only for family dog but not other dogs
overextension
- dog refers to dog and cats
- milk for white blanket, puddle
early infant speech perception
- when babies are born they can hear sounds from across a range of languages
- newborns are able to percieve many basic phoneme contrasts (hearing the differences between sounds)
- nativist view of language
- children are biologically predisposed to learn language
- children aquire language rapidly
- children acquire language effortlessly
- children acquire language without being taught
sensitive period:
- ideal time for acquiring certain parts of language - harder afterwards
- sensitive period ends by puberty once lateralisation occurs
- the case of genie
pidgins and creoles
pidgin languages:
- invented language drawing on words and grammer from a group of languages
creoles:
- when the pidgin is acquired as a native language
- gramatically more complex
- general learning capacities
- alternative views to nativist accounts
- children have highly developed pattern recognition systems
- allow children to form language categories through picking up on regularities without resorting to innate language categories
statistical learning
- children look longer at novel words, shapes and sounds
- children can internalise patterns within 2 minutes
