在两个实验中，我们测试了策略产生的个体差异是否能解释工作记忆广度任务中个体表现的差异。我们测量了在一个标准的实验者节奏的操作跨度（OSPAN）任务中使用的策略，让参与者进行策略使用的单个项目集和全局报告的设置。在实验1中，虽然规范有效的策略自我报告的OSPAN集的一小部分，有效的策略使用的个体差异与跨度性能。实验2复制了这一结果使用的样本100名参与者，但同样重要的是，它表明，有效的策略使用的个体差异并没有调解OSPAN和言语能力的措施之间的关系。讨论的重点是对策略跨度关系的解释，以及策略使用的一般报告与这里为OSPAN任务介绍的逐集报告的相对效用。
In two experiments, we tested whether individual differences in strategy production account for individual differences in performance on a working memory span task. We measured the strategies used during a standard experimenter-paced operation span (OSPAN) task by having participants make both set-by-set reports of strategy use for individual item sets and global reports of strategy use. In Experiment 1, although normatively effective strategies were self-reported on only a small proportion of OSPAN sets, individual differences in effective strategy use correlated with span performance. Experiment 2 replicated this outcome using a sample of 100 participants but, as important, it demonstrated that individual differences in effective strategy use did not mediate the relationship between OSPAN and measures of verbal ability. Discussion focuses on the interpretation of strategy-span relationships and the relative utility of general reports of strategy use versus the set-by-set reports introduced here for the OSPAN task.
