Flashcards in Speech and Language - Fitz Deck (11):
1

Outline very basically the primary language pathway:

Visual/Auditory cortex -> Wernicke's Area ->thru arcuate fasciculus -> Broca's Area -> Primary Motor Cortex

2

Assuming that an individual's handedness corresponds with their dominant hemisphere, for a right-handed person what are the general left brain functions ?

Positive emotions
Grammar and syntax
Writing
Speech

3

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)
Rudimentary speech

4

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

5

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

6

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

7

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

8

What is the difference between fluent and non-fluent aphasia?

Fluent: Generation Okay, comprehension of language is poor


Non-fluent: Comprehension okay, generation poor

9

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

Global Aphasia
--large areas of damage
--profound deficits in both

10

What is aprosody?
How does it occur?

Inability to comprehend expression of emotional qualities

Occurs with damage to the right side language equivalnets
