The performance of the human visual system exhibits moment-to-moment fluctuations influenced by multiple neurocognitive factors. To deal with this instability of the visual system, introspective awareness of current visual performance (metacognitive monitoring) may be crucial. In this study, we investigate whether and how people can monitor their own visual performance during sustained attention by adopting confidence judgments as indicators of metacognitive monitoring - assuming that if participants can monitor visual performance, confidence judgments will accurately track performance fluctuations. In two experiments (N 40), we found that participants were able to monitor fluctuations in visual performance during sustained attention. Importantly, metacognitive monitoring largely relied on the quality of target perception, a product of visual processing ("I lack confidence in my performance because I only caught a glimpse of the target"), rather than the states of the visual system during visual processing ("I lack confidence because I was not focusing on the task").
人类视觉系统的表现呈现出受多种神经认知因素影响的瞬间波动。为应对视觉系统的这种不稳定性，对当前视觉表现的内省意识（元认知监测）可能至关重要。在本研究中，我们探究人们是否以及如何能够通过采用信心判断作为元认知监测指标，在持续注意力过程中监测自身的视觉表现——假设如果参与者能够监测视觉表现，信心判断将准确跟踪表现波动。在两项实验（N = 40）中，我们发现参与者能够在持续注意力过程中监测视觉表现的波动。重要的是，元认知监测很大程度上依赖于目标感知的质量，这是视觉处理的产物（“我对自己的表现缺乏信心，因为我只是瞥见了目标”），而不是视觉处理过程中视觉系统的状态（“我缺乏信心是因为我没有专注于任务”）。
