Although the study of metamemory monitoring originated in predictions for simple span tasks, the study of metacognition for working memory (WM) has been somewhat neglected in comparison with long-term memory. We aimed to fill this gap by exploring the ability to self-assess WM operations. Thirty-four participants performed 16 series of complex span tasks and rated their confidence in a verbal recall paradigm. We manipulated the cognitive load based on the TBRS model in order to analyze the role of attentional resources on both WM and metacognitive evaluations. As expected, we found that recall is affected by cognitive load and we found standard serial position effects. Interestingly, metacognitive evaluations followed the same pattern, and measures of metacognitive sensitivity suggest that participants are able to make item-by-item retrospective judgments reflective of their performance. We discuss how these results contribute to our understanding of metacognitive access to newly-formed WM contents.
虽然内隐记忆监控的研究起源于对简单广度任务的预测，但与长时记忆相比，工作记忆 (WM) 的元认知研究多少有些被忽视。我们旨在通过探索自我评估 WM 操作的能力来填补这一空白。34 名参与者完成了 16 组复杂广度任务，并在口头回忆范式中对自己的信心进行了评分。我们根据 TBRS 模型操纵认知负荷，以分析注意力资源对 WM 和元认知评估的作用。正如预期的那样，我们发现回忆受到认知负荷的影响，并且我们发现了标准的系列位置效应。有趣的是，元认知评估也遵循相同的模式，元认知敏感性的测量表明参与者能够对反映其表现的项目进行逐项回溯判断。我们讨论了这些结果如何有助于我们理解对新形成的 WM 内容的元认知访问。
