神经心理学的发现，以及神经解剖学和神经影像学技术的最新进展，刺激了小脑对认知的贡献的研究。工作记忆是一个认知过程，一直是许多研究的焦点，特别是它的语言成分。受Baddeley工作记忆认知理论的影响，言语工作记忆任务中小脑的激活主要归因于小脑参与发音复述网络。最近的神经影像学和神经心理学研究结果与小脑在言语工作记忆中功能的简单运动观点不一致。本文探讨了这些发现及其影响的发音排练建议小脑功能。超越认知理论，我们提出了两种替代解释小脑参与言语工作记忆：错误驱动的调整和内部计时。这些关于小脑功能的一般理论已成功地改编自运动文献，以解释小脑的认知功能。我们认为，这些理论也可能提供一个有用的框架，了解非运动的小脑的贡献，言语工作记忆。
Neuropsychological findings together with recent advances in neuroanatomical and neuroimaging techniques have spurred the investigation of cerebellar contributions to cognition. One cognitive process that has been the focus of much research is working memory, in particular its verbal component. Influenced by Baddeley's cognitive theory of working memory, cerebellar activation during verbal working memory tasks has been predominantly attributed to the cerebellum's involvement in an articulatory rehearsal network. Recent neuroimaging and neuropsychological findings are inconsistent with a simple motor view of the cerebellum's function in verbal working memory. The present article examines these findings and their implications for an articulatory rehearsal proposal of cerebellar function. Moving beyond cognitive theory, we propose two alternative explanations for cerebellar involvement in verbal working memory: Error-driven adjustment and internal timing. These general theories of cerebellar function have been successfully adapted from the motor literature to explain cognitive functions of the cerebellum. We argue that these theories may also provide a useful framework to understand the non-motor contributions of the cerebellum to verbal working memory.
