When people do multiple tasks at the same time, it is often found that their performance is worse relative to when they do those same tasks in isolation. However, one aspect that has received little empirical attention is whether the ability to monitor and evaluate one's task performance is also affected by multitasking. How does dual-tasking affect metacognition and its relation to performance? We investigated this question through the use of a visual dual-task paradigm with confidence judgments. Participants categorized both the color and the motion direction of moving dots, and then rated their confidence in both responses. Across four experiments, participants (N = 87) exhibited a clear dual-task cost at the perceptual level, but no cost at the metacognitive level. We discuss this resilience of metacognition to multitasking costs, and examine how our results fit onto current models of perceptual metacognition.
当人们同时进行多项任务时，经常会发现相对于他们单独完成这些相同任务时，其表现会更差。然而，一个很少受到实证关注的方面是，监控和评估自己任务表现的能力是否也会受到多任务处理的影响。双重任务如何影响元认知及其与表现的关系？我们通过使用带有信心判断的视觉双重任务范式来研究这个问题。参与者对移动点的颜色和运动方向进行分类，然后对两种反应的信心进行评分。在四项实验中，参与者（N = 87）在感知水平上表现出明显的双重任务成本，但在元认知水平上没有成本。我们讨论了元认知对多任务成本的这种弹性，并研究了我们的结果如何适用于当前的感知元认知模型。
