Bilateral absolute auditory thresholds for frequencies ranging from 250 to 8000 Hz were examined on two occasions in schizophrenic patients and normal control subjects. Patients were classified as hallucinators and nonhallucinators on the basis of symptom ratings on both occasions. Previous evidence of better right than left ear acuity in schizophrenia was replicated but was found to characterize nonhallucinating patients only. Hallucinators showed no lateral asymmetry and inferior right ear acuity as compared with that in nonhallucinators. The results were reliable on retest. Brief Psychiatric Rating Scale scores of positive and negative symptoms in some cases differentiated hallucinators from nonhallucinators. The relationship of verbal hallucinations and right ear-left temporal lobe functions is discussed, together with complexities in cerebral laterality-syndrome relationships.
在精神分裂症患者和正常对照受试者中，对250至8000赫兹频率范围内的双侧绝对听觉阈值进行了两次检查。根据两次的症状评分，将患者分为有幻觉者和无幻觉者。先前关于精神分裂症患者右耳听力优于左耳的证据得到了重复，但发现仅在无幻觉患者中存在这一特征。与无幻觉者相比，有幻觉者未表现出侧别不对称，且右耳听力较差。复测结果可靠。在某些情况下，简明精神病评定量表的阳性和阴性症状评分可区分有幻觉者和无幻觉者。本文讨论了言语幻觉与右耳-左颞叶功能的关系，以及大脑偏侧性-综合征关系中的复杂性。
