Control of Auditory Hallucinations through Occlusion of Monaural Auditory Input

Abstract

A schizophrenic patient whose severe level of auditory hallucinations had proved refractory to neuroleptic medication was given two treatment techniques derived from Green''s theory that hallucinations represent verbal activity in the non-dominant hemisphere. Voice activity was markedly reduced in frequency and severity over a six-month period, and led to general improvements in interpersonal functioning. There was evidence for independent and additive effects of the two techniques.
