In some cases, people overestimate how much they can see. This can produce a metacognitive blind spot that may lead participants to devote fewer cognitive resources than a visual task demands. However, little research has tested whether individuals who are particularly optimistic about their visual capabilities are susceptible to poor visual performance. We tested whether optimistic metacognitive judgments would predict poor performance in a visual task, especially when it placed a large attentional load on the participant, and when it required balancing between multiple sources of information. We tested participants in a simplified battle command simulation in which they were asked to detect visual changes. Participants who predicted spatially expansive visual attention performance performed more poorly in the change detection task when the task required tracking larger numbers of aircraft, and when it included a secondary change-list display.
在某些情况下，人们会高估自己的观察能力。这可能会产生元认知盲点，导致参与者投入的认知资源少于视觉任务所需的资源。然而，很少有研究测试过那些对自己的视觉能力过于乐观的人是否容易出现视觉表现不佳的情况。我们测试了乐观的元认知判断是否会预测视觉任务中的表现不佳，特别是当它对参与者施加了大量的注意力负荷，并且需要在多个信息源之间进行平衡时。我们在简化的战斗指挥模拟中对参与者进行了测试，要求他们检测视觉变化。当任务需要跟踪更多数量的飞机，并且包括次要的变化列表显示时，那些预测空间扩展视觉注意力表现的参与者在变化检测任务中的表现更差。
