Short Answer

Expert verified
Answer: Sounds presented to the right ear are registered primarily in the left hemisphere and more quickly in the left hemisphere.

Step by step solution

01

Evaluate Option A

Option A states that sounds presented to the right ear are registered only in the right hemisphere. Due to the contralateral organization of the brain, this statement is incorrect.
02

Evaluate Option B

Option B states that sounds presented to the right ear are registered only in the left hemisphere. Based on contralateral organization, this statement is correct. When sounds are presented to the right ear, the auditory stimulus is primarily processed in the left hemisphere.
03

Evaluate Option C

Option C states that sounds presented to the right ear are registered more quickly in the right hemisphere. This statement is incorrect because, as stated in Step 2, the left hemisphere primarily processes sounds from the right ear.
04

Evaluate Option D

Option D states that sounds presented to the right ear are registered more quickly in the left hemisphere. This statement is correct and aligns with the contralateral organization.
05

Determine the Correct Answer

Based on our evaluation of each option, Options B and D are correct. Sounds presented to the right ear are registered primarily in the left hemisphere (Option B) and more quickly in the left hemisphere (Option D).
