(1)Auditory-verbal comp: primary aspects and Wernicke's

Question 1

Two primary aspects of auditory-verbal comprehension

Answer 1

1. word recognition
2. comprehension of word meaning
3. word recognition mediated by middle & posterior superior temporal gyrus

Question 2

Primary characteristics of Wernicke’s aphasia

Answer 2

1. Impaired speech comprehension
2. Production of meaningless speech
3. Poor awareness of language deficits
4. Neuropsych functioning

Question 3

re. WA: Impaired speech comprehension

Answer 3

• does not accurately follow simple instructions

- does not accurately match heard words to pictures

Question 4

re. WA: Production of meaningless speech

Answer 4

• speech is fluent
• produces high volume of syllables
• intonation generally intact
• “appears to be grammatical” i.e. uses function words: the, but
• few content words
• paraphasias
• can not repeat accurately
• expressive deficits make important to test comprehension with non-speech responses i.e. motor responses

Question 5

re. WA: poor awareness of language deficits

Answer 5

“Turn taking” intact

Question 6

re. WA: neuropsych functioning

Answer 6

• auditory association cortex of posterior superior temporal gyrus - i.e. Wernicke’s area - recognizes the sounds of words
• thought that Wernicke’s area is the location of “memories” of sequences of sounds that constitute words
