工作记忆中视觉和空间材料之间的干扰研究表明，视觉空间工作记忆存在基于领域和基于过程的细分。本研究探讨了中央基于时间的资源共享在视觉空间工作记忆中的作用，并评估了其在获得干扰模式中的作用。视觉和空间存储相结合的视觉和空间的在线加工组件在计算机节奏的工作记忆广度任务（实验1）和选择性干扰范式（实验2）。的认知负荷的处理组件进行操作，以调查其对并发维护的域内和域间组合的处理和存储组件。与基于领域和基于过程的视空间工作记忆的细分相比，结果显示，回忆成绩是由项目处理引起的认知负荷决定的，而不是由这些项目所属的领域决定的。这些发现被解释为证据的视空间工作记忆中的时间为基础的资源共享机制。
Examinations of interference between visual and spatial materials in working memory have suggested domain- and process-based fractionations of visuo-spatial working memory. The present study examined the role of central time-based resource sharing in visuo-spatial working memory and assessed its role in obtained interference patterns. Visual and spatial storage were combined with both visual and spatial on-line processing components in computer-paced working memory span tasks (Experiment 1) and in a selective interference paradigm (Experiment 2). The cognitive load of the processing components was manipulated to investigate its impact on concurrent maintenance for both within-domain and between-domain combinations of processing and storage components. In contrast to both domain- and process-based fractionations of visuo-spatial working memory, the results revealed that recall performance was determined by the cognitive load induced by the processing of items, rather than by the domain to which those items pertained. These findings are interpreted as evidence for a time-based resource-sharing mechanism in visuo-spatial working memory.
