The interaction between working memory and language processing is widely discussed in cognitive research. However, those studies often explore the relationship between language comprehension and working memory (WM). The role of WM is rarely considered in language production, despite some evidence suggesting a relationship between the two cognitive systems. This study attempts to fill that gap by using a complex span task during language production. We make our predictions based on the reorganization of elementary functions neurocognitive model, a usage based theory about grammatical status, and language production models. In accordance with these theories, we expect an overlap between language production and WM at one or more levels of language planning. Our results show that WM is involved at the phonological encoding level of language production and that adding WM load facilitates language production, which leads us to suggest that an extra task-specific storage is being created while the task is performed.
工作记忆与语言加工之间的相互作用在认知研究中得到了广泛讨论。然而，这些研究通常探讨的是语言理解与工作记忆（WM）之间的关系。尽管有一些证据表明这两个认知系统之间存在关联，但在语言产出中，工作记忆的作用很少被考虑。本研究试图通过在语言产出过程中使用复杂跨度任务来填补这一空白。我们基于基本功能神经认知模型的重组、一种关于语法地位的基于用法的理论以及语言产出模型来做出预测。根据这些理论，我们预计在语言规划的一个或多个层面上，语言产出与工作记忆会有重叠。我们的研究结果表明，工作记忆参与了语言产出的语音编码层面，并且增加工作记忆负荷有助于语言产出，这使我们提出在执行任务时正在创建一个额外的特定任务存储。
