Central auditory processing diagnosis requires exclusionary peripheral and cognitive tests
Evidence
When selecting tests that might reflect central auditory abilities, tests should assess central auditory abilities, and use peripheral or cognitive tests to rule out pathologies in those domains. Psychoacoustic tests that have been strongly linked to cochlear function and pathology, such as recruitment or masking, are not diagnostically helpful in isolation. Additionally, tests that require substantial cognitive components also should not be used in isolation. However, these tests are important for APD diagnosis, as they are needed to rule out the presence of the peripheral and cognitive pathologies. The core, informative APD tests are those that implicate central auditory processing, such as temporal processing tests and tests of binaural hearing. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1772
