采用两组数据分析了工作记忆容量（WMC）的个体差异与动态认知控制的关系。使用AX版的连续表现测试（AX- cpt），研究结果深入探讨了高wmc和低wmc个体在制定和维持认知控制能力方面的具体差异。与高wmc个体相比，低wmc个体：(a)对AX目标的错误更多；(b)表现出部分转向主动控制，更多的时间在任务上；(c)反应时间分布尾部较慢的AX靶反应更为夸张；(d)在冲突后同样有可能调整控制。这些结果符合认知控制理论和目标维持理论的双重机制，并进一步阐明了WMC的个体差异如何表现为认知控制的个体内变异。
Two datasets of 110 young adults were examined to investigate the relationship between individual differences in working memory capacity (WMC) and dynamic cognitive control. The results delve into the specific differences between high- and low-WMC individuals’ ability to enact and maintain cognitive control using the AX version of the continuous performance test (AX-CPT). Compared to high-WMC individuals, low-WMC individuals: (a) made more errors, specifically to AX targets; (b) exhibited a partial shift to proactive control with more time-on-task; (c) had more exaggerated slower AX target responses in the tail of the response time distribution; and (d) were equally likely to adjust control after conflict. These results fit with the dual mechanisms of cognitive control theory and goal-maintenance account, and further clarify how individual differences in WMC manifests as intra-individual variability in cognitive control.
