Language and Thought Flashcards
What is language?
system for communicating with others using signals that are combined according to rules of grammar and that convey meaning
What is grammar?
set of rules that specify how the units of language can be combined to produce meaningful messages
What are the 3 differences btw human language and animals?
- complex structure
- use words to define intangible things (democracy)
- use language to name, categorize, & describe things
What are phonemes?
smallest units of speech that distinguish one word from another
What are phonological rules?
indicates how phonemes can be combines to form words
What are morphemes?
- Phonemes are combined to form them
- smallest meaningful units of language
What are morphological rules?
indicates how morphemes can be combined to form words
What are the 2 types of morphemes?
- content morphemes: refer to things and events
- function morphemes: serve grammatical functions like tying sentences together
What are syntactic rules?
indicate how words can be combined to form phrases and sentences
What is telegraphic speech?
sentences devoid of function morphemes and consist mostly of content words
What is fast mapping?
in early childhood we can map a word to a concept with just a single exposure
What do critical periods suggest?
that childhood represents critical period for mastering certain aspects of language
What are the stages of language production?
- Babbling stage (4mo, sounds related to home language)
- One word stage (1-2y, single words)
- Two word stage ( 2y+, two-word statements)
- Telegraphic speech (mostly nouns and verbs)
What are Behavioural language explanations? (Skinner)
- we learn to talk the same way we acquire all other skills: reinforcement, shaping, extinction
- what is reinforced remains and what isn’t disappears from child’s repertoire
- maturing kids imitate speech patterns they hear
What is Nativism’s theory of language acquisition? (Chomsky)
- innate biological capacity for language
- brain simply acquires language through exposure to speech
- brain has universal grammar: collection of processes that facilitate language learning
What is genetic dysphasia?
- Inability to learn grammatical structure of language
- no intellectual weakness
What is interactionist theory on language acquisition?
- infants born with innate ability to acquire language
- relies on social development & interaction
- parents tailor their language to simplify language acquisition process (slow, enunciate)
What 2 brain areas deal with language?
Brocka’s area and Wernicke’s area
What condition is damage to Brocka’s area associated with?
Aphasia: difficulty comprehending/producing speech
What is Broca’s area?
- located in the left frontal cortex
- involved in the production of the sequential patterns in vocal and sign languages
What is Broca’s aphasia?
- difficulty in production of verbal language
- reduced functional morphemes
- understanding is relatively intact
- usually speak in short content morphemes
What is Wernicke’s area?
- located in the left temporal cortex
- involved in language comprehension (whether spoken or signed)
What is Wernicke’s Aphasia?
- caused by damage to Wernicke’s area
- can produce grammatical speech, but it tends to be meaningless
- have considerable difficulty comprehending language
