Auditory sensitivity in psychiatric patients and non-patients: monotic click detection

Abstract

SYNOPSISThe sensitivity in detecting a click was measured separately for the right and left ear of psychiatric patients and non-patient controls using a three-interval forced-choice staircase procedure. Patients with affective disorders showed reduced right ear sensitivity, while schizophrenic patients did not show reduced sensitivity. Lower sensitivity correlated with higher structured-interview ratings of speech retardation.
