以往的工作记忆双任务协调研究表明，当言语记忆任务与并发知觉跟踪相结合时，双任务干扰缺乏。报告了两个实验，其中要求参与者执行（1）言语记忆任务，视觉记忆任务和感知跟踪（实验1）的成对组合，以及（2）两个记忆任务和发音抑制（实验2）的成对组合。跟踪导致的口头记忆的前负荷没有中断以上的延迟召回的影响，并显示只有最小的破坏的视觉记忆负荷的保留。执行一个正在进行的文字记忆任务几乎没有影响保留的视觉记忆预负荷，反之亦然，表明执行两个要求高的记忆任务的结果很少相互干扰。实验2也表明，最小的中断时，这两个记忆任务相结合，虽然口头记忆（但不是视觉记忆）明显中断的发音抑制插入演示和回忆。这些数据表明，一个多组件的工作记忆模型提供了一个更好的帐户在并发即时记忆任务的性能比理论，假设一个单一的处理和存储系统或有限的容量注意力系统与激活的记忆痕迹。
Previous studies of dual-task coordination in working memory have shown a lack of dual-task interference when a verbal memory task is combined with concurrent perceptuomotor tracking. Two experiments are reported in which participants were required to perform pairwise combinations of (1) a verbal memory task, a visual memory task, and perceptuomotor tracking (Experiment 1), and (2) pairwise combinations of the two memory tasks and articulatory suppression (Experiment 2). Tracking resulted in no disruption of the verbal memory preload over and above the impact of a delay in recall and showed only minimal disruption of the retention of the visual memory load. Performing an ongoing verbal memory task had virtually no impact on retention of a visual memory preload or vice versa, indicating that performing two demanding memory tasks results in little mutual interference. Experiment 2 also showed minimal disruption when the two memory tasks were combined, although verbal memory (but not visual memory) was clearly disrupted by articulatory suppression interpolated between presentation and recall. These data suggest that a multiple-component working memory model provides a better account for performance in concurrent immediate memory tasks than do theories that assume a single processing and storage system or a limited-capacity attentional system coupled with activated memory traces.
