Sounds presented to the right ear are registered:

Correct Answer: More quickly in the left hemisphere

Although auditory information from each ear reaches both hemispheres, there is a stronger contralateral (crossed) pathway. Therefore, sounds presented to the right ear reach the left hemisphere more directly. Since the left hemisphere is usually dominant for language, speech sounds presented to the right ear are typically processed more quickly.

Why the other options are incorrect:

• Only in the right hemisphere: Incorrect. Auditory signals are processed by both hemispheres.
• Only in the left hemisphere: Incorrect. Both hemispheres receive auditory input from each ear.
• More quickly in the right hemisphere: Incorrect. The stronger contralateral pathway carries right-ear input more directly to the left hemisphere.
