CAPD involves deficits in processing in which neural system?

• A. Peripheral vestibular system.
• B. Somatosensory system.
• C. Visual cortex.
• D. Central Auditory Nervous System.

Answer: (D)

Central auditory processing problems stem from how the brain processes sound, not from the ear itself. CAPD reflects deficits in the central auditory nervous system, which includes pathways from the brainstem up to the auditory cortex where timing, sound discrimination, and integration across both ears are coded and interpreted. When these neural processing steps are less efficient, tasks like distinguishing similar sounds, following rapid speech, or understanding speech in noisy environments become difficult even if pure-tone hearing is normal. The peripheral vestibular system, somatosensory system, and visual cortex are not the sites of this auditory processing, so issues in balance, touch, or sight do not explain CAPD.
