Language and Thought Flashcards
Language
Consists of the use of symbols to represent, transmit, and store meaning / info
- Symbols include organized patterns of sound, visual representations, and movements
- Meaning includes concepts, quantities, plans, identity, feelings, ideas, facts, and customs
Composed of phonemes, morphemes, and grammar
What are the uses of language
- Provides a means to relay info
- Allows ppl to connect to ppl far away
- Allows for planning / execution of schemes
Phoneme
Smallest units of sound
eg. vowels and consonants
Morpheme
Units of meaning
eg. words / meaning parts of words; pre-/suffixes
Grammar
The rules for using words, including semantics, definitions, connotations, and syntax
ie. how the order of words make meaning
Language Development in Children
(0-4mon) receptive language
(4mon) productive language
(10mon) babbling sounds more like household language
(12mon) one-word stage, esp. nouns
(18-24mon) two-word, telegraphic speech: addition of verbs, constructing phrases
(24mon+) full, complex sentences
Nature vs Nurture in Language
We seem to have an genetic talent for acquiring language, but we also seem to have a “statistical” patter recognition talent
Critical Period for Learning Language
Development of language centers of the brain peaks at 3-7yrs; after that the development decreases linearly
How do deaf and blind children develop language skills?
Deaf / blind children se complex adapted language by using other senses that are heightened
eg. sign language
Aphasia
Impairment in the ability to produce / understand language; caused by brain damage
Broca’s Aphasia
Aphasia w/ difficulty in constructing sentences, speaking single words; does not affect the ability to sing
Wernicke’s Aphasia
Aphasia w/ difficulty in comprehending speech, producing coherent speech
Written Language Processing Pathway
- Visual cortex receives written words as visual stimulation
- Angular gyrus transforms visual codes into auditory ones
- Wernicke’s area interpret’s auditory code
- Broca’s area controls speech muscles via motor cortex
- Motor cortex allows word to be pronounced
Receptive Language
Associating sounds w/ facial movements
Recognizing when sounds are broken into words
Occurs in 0~4mon babies, dogs
Productive Language
Multilingual babbling / gestures
Occurs in 4mon babies, bees (dances), chimps (sign language)
