Recently, a number of experiments have emphasized the degree to which subjects fail to detect large changes in visual scenes. This finding, referred to as "change blindness," is often considered surprising because many people have the intuition that such changes should be easy to detect. documented this intuition by showing that the majority of subjects believe they would notice changes that are actually very rarely detected. Thus subjects exhibit a metacognitive error we refer to as "change blindness blindness." Here, we test whether CBB is caused by a misestimation of the perceptual experience associated with visual changes and show that it persists even when the pre- and postchange views are separated by long delays. In addition, subjects overestimate their change detection ability both when the relevant changes are illustrated by still pictures, and when they are illustrated using videos showing the changes occurring in real time. We conclude that CBB is a robust phenomenon that cannot be accounted for by failure to understand the specific perceptual experience associated with a change.
最近，一些实验强调了受试者未能察觉到视觉场景中巨大变化的程度。这一发现，即所谓的“变化盲视”，常常令人惊讶，因为许多人直觉上认为这类变化应该很容易被察觉。通过表明大多数受试者相信他们会注意到实际上很少被察觉到的变化，记录了这种直觉。因此，受试者表现出一种我们称之为“变化盲视盲”的元认知错误。在这里，我们测试了变化盲视盲是否由对与视觉变化相关的感知体验的错误估计引起，并表明即使前后变化视图被长时间延迟隔开，这种现象仍然存在。此外，当相关变化由静态图片展示时，以及当使用显示实时发生变化的视频展示时，受试者都高估了自己的变化检测能力。我们得出结论，变化盲视盲是一种稳健的现象，不能用未能理解与变化相关的特定感知体验来解释。
