一个并行任务的方法被用来调查工作记忆资源的各个方面的可用性与策略选择和执行之间的关系，而简单的加法方程（例如，4 + 3 = 8）。与先前的研究中，生产试验已被使用，本科生选择了各种程序以外的检索。工作记忆资源的可用性一般不会影响策略的选择。扰乱中央执行和语音方面的记忆影响策略执行，但只有当最小计数被用来解决问题。这些和其他功能的结果表明，工作记忆资源的可用性并没有贡献的策略选择和执行提取过程的时间的个体差异。
A concurrent-task methodology was used to investigate relations between the availability of aspects of working memory resources and both strategy selection and execution while simple addition equations (e.g., 4 + 3 = 8) were being verified. Consistent with prior research in which production trials have been used, undergraduates selected a variety of procedures other than retrieval. Availability of working memory resources did not generally affect strategy selection. Disrupting central executive and phonological aspects of memory affected strategy execution, but only when min counting was used to solve the problems. These and other features of the results suggest that availability of working memory resources does not contribute to individual differences in strategy selection and time to execute retrieval processes.
