本研究采用双任务干扰范式来检验工作记忆的不同子成分对字母流畅性和类别流畅性任务表现的差异。大学生（N = 96）分别独立完成每种语言流畅性任务，并同时完成3个辅助任务中的1个。次要任务的选择是因为它们被假定参与了不同的工作记忆子组件。工作记忆的两个子系统，语音回路和视觉空间画板，分别被认为是流利性表现的重要贡献者，特别是在字母流利和类别流利任务中的表现。此外，结果还表明，执行功能，心理定式转移，可能部署在字母流畅性和类别流畅性任务。
This study used a. dual-task interference paradigm to test the hypothesis that different subcomponents of working memory differentially contribute to performance on letter fluency and category fluency tasks. College students (N = 96) performed each type of verbal fluency task in isolation and concurrently with 1 of 3 secondary tasks. The secondary tasks were chosen for their putative involvement in different working memory subcomponents. Two subsystems of working memory, the phonological loop and the visuospatial sketchpad, were identified as important contributors to fluency performance, especially to performance on letter fluency and category fluency tasks, respectively. Moreover, the results also suggest that the executive function, mental set shifting, may be deployed to perform both letter fluency and category fluency tasks.
