Dichotic Listening in Psychotic Patients

Abstract
Summary: Patients recently recovered from schizophrenic or manic-depressive psychoses showed larger ear difference scores than normal controls on a dichotic listening test, i.e. when asked to identify dissimilar words fed synchronously to the two ears. The possible significance of the finding is discussed, in relation both to hemispheric organization and to other aspects of cognitive activity which may underlie performance on the task.
