语音回路和视空间模板对音位流畅性和语义流畅性的影响

The Impact of the Articulary Loop and Visuospatial sketchpad on Phonemic and Semantic Fluency

采用双任务范式，通过四种次任务考察了工作记忆两个子系统-语音回路和视空间模板对音位流畅性和语义流畅性的影响。实验1表明，主动产生系列发音和被动聆听声音判断对音位流畅性影响更大，表明音位流帐性更依赖于语音回路。实验2表明，字形匹配和字形旋转判断对语义流畅性影响更大，表明语义流畅性更依赖于视空间模板。研究还表明，被试完成音位流畅性任务的策略更易受语言的特点影响，完成语义流畅性任务的策略更易受概念系统的特性影响。

Verbal fluency is typically measured by generative naming tasks. The two types of verbal fluency that are generally tested are (1) phonemic fluency， in which the subjects generate words beginning with a particular letter， and (2) semantic fluency， in which the subjects produce items from a specified category. Most of the previous studies primarily focused on the contribution of the central executive function to phonemic and semantic fluency; however， little attention was paid to the contribution
