Module 28 Flashcards
(44 cards)
language
the use of symbols to represent, transmit, and store meaning/information
symbols
organized patterns of sounds, visual representations, and movements
meaning
concepts, quantities, plans, identity, feelings, ideas, facts, and customs
phonemes
smallest units of sound (vowels and consonants)
morphemes
units of meaning - unladylike = un, lady, like
include suffixes and prefixes
phonemes
smallest units of sound (vowels and consonants)
grammar
rules for using words, including semantics, definitions, connotations, and syntax
use of language
- understanding phenomena we have never experienced
- connecting to people far away
- make plans for others to carry out
- know that another person is thinking more directly than just by their behavior
- store information
language development
very fast
- 10 new words/day between 2-18yrs
- basic grammar before they can add 2+2
- recall words and meanings, assemble words into sentences, while simultaneously following social rules for speaking and listening
1) receptive
2) productive
3) one word
4) two word
receptive language
(0-4 mos)
associating sounds with facial movements, and recognizing when sounds are broken into words
productive language (humans)
(4 mos)
babbling in multilingual sounds and gestures
babbling at (10 mos)
babbling sounds more like the parents’ household’s language
one-word stage
(12 mos)
understanding and beginning to say many nouns
two-word, telegraphic speech
(18-24 months)
adding verbs and making sentences but missing words
24+ months, 2+ years language
full sentences and understanding complex sentences
role of genes in language acquisition (nature)
inborn, genetic talent for acquiring language, though no particular kind of language in the genes
role of experience in language acquisition (nurture)
“statistical” pattern recognition talent. Infants quickly recognize patterns in syllable frequency and sequence, preparing them to later learn words and syntax
critical period of language acquisition
- important to begin appropriate language exposure/education early so that language centers of the brain continue to develop
- genetic and environmental
- may never develop if not begun by age 7
- learning pronunciation and grammar of 2nd language more difficult with age
deaf and blind children: adapted languages
– heightened other senses
sign language: same syntax, grammar, and complex meaning of any spoken language
aphasia
an impairment in the ability to produce or understand language, usually caused by damage to the brain
example of aphasia:
having the ability to read, to produce words in song but not in conversation, and to speak but not repeat; or producing words in jumbled order
Broca’s area, left frontal lobe
results of damage
leads to difficulty in putting words together in sentences or even speaking single words, although a person can sing a song or swear
Wernicke’s area, left temporal lobe
results of damage
leads to difficulty comprehending speech and producing coherent speech (not easily monitoring one’s own speech to make sure it makes sense)
Steps to reading a word:
1) visual cortex
receives written words as visual stimulation
