R11 Questions

Question 1

Where is Broca’s area located? According to these authors, why is that a sensible place for it?

Answer 1

Broca’s area is located next to the part of the motor cortex that controls the muscles of the mouth and lips. This is a sensible place for it because Broca’s is involved in speech production.

Question 2

Where is Wernicke’s area located? According to these authors, why is that a sensible place for it?

Answer 2

Wernicke’s area is located near the auditory cortex. It’s a sensible location because it is involved in speech comprehension, and the auditory cortex receives signals from the ears.

Question 3

Why do these authors hypothesize that sign language might be lateralized in the right hemisphere?

Answer 3

The signs are visual-spatial signals, and the right hemisphere oversees visual-spatial tasks.

Question 4

Do deaf signers with brain damage show dissociable deficits of language production (like Broca’s aphasia) and language understanding (like Wernicke’s aphasia)? (Yes/No)

Answer 4

Yes

Question 5

Damage to the (right/left) hemisphere in signers underlies most acquired impairments in sign language use.

Answer 5

Left

Question 6

What aspect of language is most sharply restricted to the left hemisphere?

Answer 6

Language production

Question 7

An alternative way of looking at language lateralization in deaf and hearing people is that language at the “local” level (word deciphering, etc.) is lateralized to the (left/right) whereas the more global aspect of putting together discourse is lateralized the (left/right).

Answer 7

left; right

Question 8

What do these authors conclude about the relationship between the sign language abilities of life-long signers and their non-linguistic spatial skills?

Answer 8

The sign language abilities of lifelong deaf signers are independent of their nonlinguistic spatial skills.
