语言流畅性测试是一种常用的神经心理学测试，属于词汇生成任务。在健康人群中，它已被用于评估语言能力，但也执行功能。在临床领域，语言流畅性已被用于支持许多神经心理障碍的诊断。然而，现有的证据并不允许明确的结论，这种非语言使用的口头流利性测试是合理的。因此，本研究调查的参与域一般认知功能的文字生产使用功能性磁共振成像，评估语言流畅性，反应抑制，工作记忆更新大脑激活在同一组的参与者。结果表明，反应抑制和工作记忆更新在言语流利型词汇产生任务中确实发挥了作用，尽管语言特异性区域也是必需的。此外，一般领域和特定语言区域是同一个大脑区域内紧密相邻的子区域。此外，神经网络的汉语词汇生产，这证实了在字母语言生产的神经基础，表明有一个核心网络的词汇生产，无论语言，生产模式，或线索刺激类型，与其他额外的领域涉及在某些生产条件下。鉴于大多数以前的研究只调查了字母语言，这些结果有助于更好地了解跨语言的语言产生机制。
Verbal fluency test, a type of word generation task, is a commonly used neuropsychological assessment. Among the healthy population, it has been used to assess verbal ability, but also executive functions. In the clinical field, verbal fluency has been used to support the diagnoses of a number of neuropsychological disorders. However, existing evidence do not allow for clear conclusions on whether such nonlinguistic uses of verbal fluency test are justified. The present study therefore investigated the involvement of domain-general cognitive functions in word production using functional magnetic resonance imaging, assessing verbal fluency, response inhibition, and working memory updating brain activations in the same set of participants. Results showed that response inhibition and working memory updating do play a role in verbal-fluency-type word production tasks, although language-specific regions are also required. Furthermore, domain-general and language-specific areas are closely neighboring subregions within the same broad brain regions. Additionally, a neural network for Chinese lexical production was observed, which corroborate neural bases for production in alphabetic languages, indicating that there is a core network for lexical production, regardless of language, production mode, or cue stimulus type, with other additional areas involved under some production conditions. Given that most previous research only investigated alphabetic languages, these results help gain a better understanding of language production mechanisms across languages.
