title: Disorders of auditory processing: evidence for modularity in audition.
abstract: This article examines four disorders of auditory processing that can result from selective brain damage (cortical deafness, pure word deafness, auditory agnosia and phonagnosia) in an effort to derive a plausible functional and neuroanatomical model of audition. The article begins by identifying three possible reasons why models of auditory processing have been slower to emerge than models of visual processing: neuroanatomical differences between the visual and auditory systems, terminological confusions relating to auditory processing disorders, and technical factors that have made auditory stimuli more difficult to study than visual stimuli. The four auditory disorders are then reviewed and current theories of auditory processing considered. Taken together, these disorders suggest a modular architecture analogous to models of visual processing that have been derived from studying neurological patients. Ideas for future research to test modular theory more fully are presented.
