Language Flashcards
How speech is made
Vocal folds trap air and vibrations form oscillatory waves at 100-400hz
Formants
Nasal sinuses and vocal tract modulate the power of sound
Formants
Nasal sinuses and vocal tract modulate the power of sound
Language levels
phonemes-sounds we can make
Morphemes-small unit with meaning un ed
Syntax-Phrases put in an order
Language development
Infants have speech perception very early whereas speech production around 12 months(just make random sounds till then)
Skinner and Chomsky
Skinner-children learn Language through nurture/conditioning Chomsky-Children learn language innately(built in module in the brain)
Categorical perception
Children have the ability to pick up acoustic changes between phonemes
Infants built with linguistic universalists are able to tell when word starts and stop in any language
Speech production and perception
Speech production changes with perception and at 12 months baby start to produce vowel constants
At 2 years they can mimic language sounds
Sound being visual
Take in how the mouth moves to make the sound
Critical period for language learning
5-12 years old
Areas of the brain involved with language
Brocas area Wernickes area Primary motor cortex Primary auditory cortex Primary somatosensory cortex Primary visual cortex
Broca and Wernicke area
Involed with sounds heard, spoken and writing
Came up with localisation of language
Wernicke is to do with speech and comprehension
Broca involved with grammar
Aphasia
when a person has difficulty with their language or speech
Analyses done on patients to find Wernicke and Broca area post mortem
There is Broca and Wernicke aphasia types
Epileptic Aphasia
Childhood disorder were epilepsy makes child unable to understand language
PROSODY
The emotion in language
