title: Phonological fluency is uniquely impaired in Japanese-speaking schizophrenia patients: confirmation study.
abstract: 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.
