Question

Deaf people who use sign language typically

A. demonstrate greater mathematical competence than hearing persons.
B. process language in their left cerebral hemisphere.
C. recognize facial expressions of emotion with their left rather than their right cerebral hemisphere.
D. have a smaller corpus callosum than hearing persons

Answer 1

Deaf people who use sign language typically process language in their left cerebral hemisphere, adhering to the general pattern of language localization in the cerebral cortex for most of the population. The correct option is B.

Step-by-step explanation:

The student is asking which statement accurately describes deaf people who use sign language. The correct answer is that deaf people who use sign language typically process language in their left cerebral hemisphere, similar to hearing individuals.

This is because the language functions of the cerebral cortex are mostly localized to the left hemisphere in about 95 percent of the population.

While damage to the right hemisphere can affect the use of language and nonverbal aspects like facial expression or body language, it does not refute the localization of core language functions to the left hemisphere. Option B. is the correct one.
