工作记忆（WM）文献中包含了许多不同维度的任务，比如何时或如何报告记忆项目。除了WM任务的设计方式不同之外，任务也可能根据参与者在任务执行过程中使用的策略而产生差异。本研究包括来自WM文献的七个任务，每个任务都需要短期记忆口头项目。在完成每个任务的少量试验后，受试者完成一份自我报告问卷，以确定他们的主要策略。结果表明，对于给定的任务，个体之间存在着巨大的差异，在同一个体内部，不同的任务之间也存在着巨大的差异。此外，虽然任务之间的直接比较表明，尽管任务要求不同，但一些任务表现出相似的策略使用模式，而另一些任务表现出明显不同的自我报告策略使用模式。社区检测算法旨在根据个体的策略选择概况识别个体群体，揭示了在不同需求下依赖特定策略的个体独特社区。总之，这些发现表明，使用共同工作记忆范式的研究人员在解释他们的研究结果时，应该非常仔细地考虑策略使用变化的含义。
The working memory (WM) literature contains a number of tasks that vary on dimensions such as when or how memory items are reported. In addition to the ways in which WM tasks are designed to differ, tasks may also diverge according to the strategies participants use during task performance. The present study included seven tasks from the WM literature, each requiring short-term retention of verbal items. Following completion of a small number of trials from each task, individuals completed a self-report questionnaire to identify their primary strategy. Results indicated substantial variation across individuals for a given task, and within the same individual across tasks. Moreover, while direct comparisons between tasks showed that some tasks evinced similar patterns of strategy use despite differing task demands, others showed markedly different patterns of self-reported strategy use. A community detection algorithm aimed at identifying groups of individuals based on their profile of strategic choices revealed unique communities of individuals who are dependent on specific strategies under varying demands. Together, the findings suggest that researchers using common working memory paradigms should very carefully consider the implications of variation in strategy use when interpreting their findings.
