Multiple choice

How does the brain process sign language in deaf individuals who have never been exposed to spoken language?

  1. The brain processes sign language in deaf individuals who have never been exposed to spoken language in the same way that it processes sign language in deaf individuals who have been exposed to spoken language.

  2. The brain processes sign language in deaf individuals who have never been exposed to spoken language in a different way than it processes sign language in deaf individuals who have been exposed to spoken language.

  3. The brain does not process sign language in deaf individuals who have never been exposed to spoken language.

  4. The brain processes sign language in deaf individuals who have never been exposed to spoken language in both the same and different ways than it processes sign language in deaf individuals who have been exposed to spoken language.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The brain processes sign language in deaf individuals who have never been exposed to spoken language in both the same and different ways than it processes sign language in deaf individuals who have been exposed to spoken language. Some aspects of the brain's processing of sign language are the same in deaf individuals who have never been exposed to spoken language and deaf individuals who have been exposed to spoken language, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in deaf individuals who have never been exposed to spoken language and deaf individuals who have been exposed to spoken language, such as the involvement of the hand motor cortex in deaf individuals who have never been exposed to spoken language.

Multiple choice

How does the brain process sign language in individuals who have aphasia?

  1. The brain processes sign language in individuals who have aphasia in the same way that it processes sign language in individuals who do not have aphasia.

  2. The brain processes sign language in individuals who have aphasia in a different way than it processes sign language in individuals who do not have aphasia.

  3. The brain does not process sign language in individuals who have aphasia.

  4. The brain processes sign language in individuals who have aphasia in both the same and different ways than it processes sign language in individuals who do not have aphasia.

D Correct answer
Explanation

The brain processes sign language in individuals who have aphasia in both the same and different ways than it processes sign language in individuals who do not have aphasia. Some aspects of the brain's processing of sign language are the same in individuals who have aphasia and individuals who do not have aphasia, such as the activation of the angular gyrus. However, other aspects of the brain's processing of sign language are different in individuals who have aphasia and individuals who do not have aphasia, such as the involvement of Broca's area and Wernicke's area in individuals who have aphasia.

Multiple choice

Which neural mechanism is thought to underlie language disorders such as aphasia?

  1. Damage to Broca's area

  2. Damage to Wernicke's area

  3. Damage to the arcuate fasciculus

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Language disorders such as aphasia can result from damage to Broca's area, Wernicke's area, or the arcuate fasciculus, which connects these two regions. Damage to any of these areas can disrupt language processing and lead to difficulties with speaking, understanding, or both.
