Inability to recognize other people’s voice…caused by a damage to the right superior temporal cortex

Question 4

What is aphasia and what are the 2 aphasia categories?

Answer 4

Disturbance in understanding, producing or repeating meaningful speech
-Frontal lobe damage–>can’t produce speech
-Sensory association cortex damage–>can’t understand

Question 5

What is the interface of the concept networks and the language networks (ex: seeing a dog vs seeing the word “dog”)

Answer 5

Posterior language area (PLA)
-wraps around lateral fissure
-damage=loss of understanding of words, can’t link to other representations…can’t activate networks

-“fluent aphasia”
- Participate in conversations without using words…prosody; can still convey emotions
-No frustration

Answer 7

-Transcortical sensory aphasia + pure word deafness
- Damage to both Wernicke’s area and PLA
-Can’t repeat
-Prosody is okay
-No frustration

Question 8

Answer 8

-Can speak intelligently,

Question 9
