Working memory is thought to be strongly related to cognitive control. Recent studies have sought to understand this relationship under the prism of the dual mechanisms of control (DMC) framework, in which cognitive control is thought to operate in two distinct modes: proactive and reactive. Several authors have concluded that a high working memory capacity is associated with a tendency to engage the more effective mechanism of proactive control. However, the predicted pattern of proactive control use has never been observed; correlational evidence is made difficult to interpret by the overall superiority of participants with a high working memory capacity: they tend to perform better even when proactive control should be detrimental. In two experiments, we used an experimental-correlational approach to experimentally induce the use of reactive or proactive control in the AX-CPT. The relation between working memory capacity and performance was unaffected, incompatible with the hypothesis that the better performance of participants with a high working memory capacity in the task is due to their use of proactive control. It remains unclear how individual differences in working memory capacity relate to cognitive control under the DMC framework.
工作记忆被认为与认知控制密切相关。最近的研究试图在双重控制机制（DMC）框架下理解这种关系，在该框架中，认知控制被认为以两种不同的模式运行：前摄和反应。一些作者得出结论，高工作记忆容量与倾向于采用更有效的前摄控制机制有关。然而，从未观察到预测的前摄控制使用模式；相关证据因高工作记忆容量参与者的整体优势而难以解释：即使前摄控制应该有害，他们往往表现得更好。在两项实验中，我们使用实验相关的方法在 AX-CPT 中实验性地诱导反应性或前摄性控制的使用。工作记忆容量与表现之间的关系不受影响，与假设参与者高工作记忆容量在任务中的更好表现归因于他们使用前摄控制不一致。在 DMC 框架下，工作记忆容量与认知控制之间的个体差异如何相关仍不清楚。
