摘要： 深入研究精神分裂症患者特异性的认知障碍有助于精神分裂症的早期发现、早期诊断和早期治疗。本综述在总结精神分裂症患者的听觉和言语识别异常以及听觉注意和听觉工作记忆缺陷的同时, 重点阐述了精神分裂症患者完成言语听觉任务时的对掩蔽刺激特别信息掩蔽刺激的异常易感性。本文还特别指出, 精神分裂症患者仍然具有利用言语内容启动线索来提高掩蔽下言语识别的能力。本文所总结的研究成果对探讨精神分裂症的病因学基础、寻找新的临床诊断以及治疗和康复手段都具有参考价值。

Abstract: Some cognitive deficits are specifically trait-related to schizophrenia and are important for early detection, diagnosis, and treatment of this mental disorder. This article reviews the literature on deficits of schizophrenic patients in auditory masking tasks, auditory attention, and auditory working memory, and particularly put the emphasis on the vulnerability of speech recognition to masking stimuli, especially informational masking stimuli. This article will facilitates both the understanding of the etiology of schizophrenia and the explosions of new methods for early diagnosis and treatment of this mental disorder.
