How does ASHA define Central Auditory Processing Disorder (CAPD)?

• A. A peripheral hearing loss.
• B. A speech-language pathology issue unrelated to hearing.
• C. Deficits in neural processing of auditory information in the Central Auditory Nervous System not due to higher order language or cognition.
• D. A deficit in articulation.

Answer: (C)

Central Auditory Processing Disorder is about how the brain processes sounds, not about the sound being heard by the ears. ASHA describes CAPD as deficits in neural processing of auditory information in the Central Auditory Nervous System that are not due to higher-order language or cognitive factors. In other words, someone can have normal peripheral hearing yet struggle to interpret or organize sounds—especially in challenging listening situations like in noise or with rapid speech—because the brain’s auditory pathways aren’t processing the information efficiently. This distinction matters: CAPD is about CNS processing, while a peripheral hearing loss involves the ear’s ability to detect sound. It also helps separate CAPD from articulation problems (which are about producing sounds) and from language or cognitive disorders that aren’t specifically about auditory processing.
