Previous research showed an important association between reading and writing skills (literacy) and the phonological loop. However, the effects of literacy on other working memory components remain unclear. In this study, we investigated performance of illiterate subjects and their matched literate controls on verbal and nonverbal working memory tasks. Results revealed that the phonological loop is significantly influenced by literacy, while the visuospatial sketchpad appears to be less affected or not at all. Results also suggest that the central executive might be influenced by literacy, possibly as an expression of cognitive reserve.
先前的研究表明阅读和写作技能（读写能力）与语音回路之间存在重要关联。然而，读写能力对其他工作记忆成分的影响尚不清楚。在这项研究中，我们调查了文盲受试者及其匹配的有文化受试者在言语和非言语工作记忆任务中的表现。结果表明，语音回路受到读写能力的显著影响，而视空间草图则受影响较小或不受影响。结果还表明，中央执行器可能受到读写能力的影响，这可能是认知储备的一种表现。
