Functional asymmetries in the auditory system.
This paper describes interaural differences in a variety of listening tasks. We summarize both behavioral and electrophysiologic evidence that performance, in persons with both normal and impaired hearing, differs according to which ear is stimulated. The effect extends over the entire age range, but is especially evident in children and elderly persons. Results are presented in three area: 1) cued listening, 2) dichotic words and sentences, and 3) temporal resolution. Some possible clinical implications of functional asymmetries are discussed.
