In alphabet-based language-speaking patients with schizophrenia, category fluency is disproportionately disturbed as compared with phonological fluency. Deficits in category and phonological fluency observed in Japanese patients, however, were similar. The aim of the present study was to replicate these findings by modifying the task to minimize the influence of lack of motivation and concentration in the patients. Similar deficits were found in both types of fluency in Japanese patients. Patients who speak Japanese have deficits in phonological fluency, compared with patients who speak alphabet-based languages, suggesting that the pattern of impairment in verbal fluency in schizophrenia is dependent on the specific language system.
在以字母为基础的语言的精神分裂症患者中，与语音流畅性相比，类别流畅性受到不成比例的干扰。然而，在日本患者中观察到的类别和语音流畅性缺陷是相似的。本研究的目的是通过修改任务来复制这些发现，从而最大限度地减少患者缺乏动机和注意力的影响。在日本患者中，两种流畅性都存在类似的缺陷。与以字母为基础的语言的患者相比，说日语的患者在语音流畅性方面存在缺陷，这表明精神分裂症患者言语流畅性损伤的模式取决于特定的语言系统。
