Specific auditory perceptual dysfunction in a learning disabled child

An 11 1/2 year old child with learning disability was evaluated with a battery of auditory and linguistic test procedures: electrophysiologic (auditory brain stem, middle latency response, and late potentials), electroacoustic (stapedial reflexes), and behavioral (measures of phonetic-phonologic, syntactic, and semantic processing). The overall pattern of results suggested the presence of an isolated auditory-phonologic processing disorder. Results supported an auditory-perceptual, as opposed to a linguistic-cognitive, model of learning disability.
