Working memory researchers do not agree on whether order in serial recall is encoded by dedicated modality-specific systems or by a more general modality-independent system. Although previous research supports the existence of autonomous modality-specific systems, it has been shown that serial recognition memory is prone to cross-modal order interference by concurrent tasks. The present study used a serial recall task, which was performed in a single-task condition and in a dual-task condition with an embedded memory task in the retention interval. The modality of the serial task was either verbal or visuospatial, and the embedded tasks were in the other modality and required either serial or item recall. Care was taken to avoid modality overlaps during presentation and recall. In Experiment 1, visuospatial but not verbal serial recall was more impaired when the embedded task was an order than when it was an item task. Using a more difficult verbal serial recall task, verbal serial recall was also more impaired by another order recall task in Experiment 2. These findings are consistent with the hypothesis of modality-independent order coding. The implications for views on short-term recall and the multicomponent view of working memory are discussed.
在序列回忆中，顺序是由专门的特定模态系统编码，还是由更通用的非模态特定系统编码，工作记忆研究人员对此尚无定论。尽管先前的研究支持自主特定模态系统的存在，但研究表明，序列识别记忆容易受到并发任务的跨模态顺序干扰。本研究采用了序列回忆任务，该任务在单任务条件下以及在双任务条件下进行，在保持间隔中嵌入了记忆任务。序列任务的模态要么是言语的，要么是视觉空间的，而嵌入任务则采用另一种模态，需要序列回忆或项目回忆。在呈现和回忆过程中注意避免模态重叠。在实验1中，当嵌入任务是顺序任务时，视觉空间序列回忆比其是项目任务时受到的损害更大，但言语序列回忆并非如此。在实验2中，使用更难的言语序列回忆任务时，言语序列回忆也会因另一个顺序回忆任务而受到更大损害。这些发现与非模态特定顺序编码的假设一致。本文还讨论了这些发现对短期回忆观点和工作记忆多成分观点的影响。
