Flashcards in Speech and Language - Fitz Deck (11):
Outline very basically the primary language pathway:
Visual/Auditory cortex -> Wernicke's Area ->thru arcuate fasciculus -> Broca's Area -> Primary Motor Cortex
Assuming that an individual's handedness corresponds with their dominant hemisphere, for a right-handed person what are the general left brain functions ?
Grammar and syntax
Assuming that an individual's handedness corresponds with their dominant hemisphere, for a right-handed person what are the general right brain functions ?
Recognition of emotions and negative emotions
Prosody & recognition of emotional content of speech
Spatial abilities (ex. face recognition)
How do the three primary organs act to alter speech production?
o Lungs, which act as an air reservoir
o Larynx, which generates the pulsatile quality of "voiced" sounds due to the actions of the vocal folds
o Pharynx and the oral and nasal cavities, which filter the sounds, making them characteristic of an individual's voice
What is gershwind's territory?
Located in inferior parietal lobe - multimodal
Output synapses to both Wernicke's and Broca's area
Responsible for recognition and labeling of items
Matures later, may be keeping kids from reading
Describe the stages of speech:
Airstream in lungs
Vibration of vocal cord - open and close at fundamental frequency that determines your pitch
Filtering by vocal tract - formant peaks created by altering in shape of your vocal tract - makes vowel sounds!!!!!
Opening and closing of vocal folds - produces consonant sounds
What do we do with phones?
NO we don't call people with them...
200 phones - combine to form syllables - syllables make words - words make sentences
What is the difference between fluent and non-fluent aphasia?
Fluent: Generation Okay, comprehension of language is poor
Non-fluent: Comprehension okay, generation poor
What re the 4 different types of dysphasia?
Receptive aphasia - Wernicke's
--deficits in auditory and written comprehension
Conductive Aphasia - Arcuate Fasciculus (fluent)
--cannot repeat words
--inability to come up with words (Gershwimd's)
Expressive Aphasia - Broca's (non-fluent)
--impaired verbal and oral expression
--imparied organization and control of speech
--large areas of damage
--profound deficits in both
What is aprosody?
How does it occur?
Inability to comprehend expression of emotional qualities
Occurs with damage to the right side language equivalnets
