尽管我们的主观印象是一个非常详细的视觉世界，但大量的实验结果表明，观察者在任何给定时刻能够感知和记住的视觉信息量是有限的。我们的主观印象如何与这些客观观察相一致？在这里，我们回答这个问题的理由是，尽管我们看到的物体比视觉注意力和工作记忆的杰出模型所声称的少数几个物体要多，但我们看到的东西仍然比我们想象的要少得多。综上所述，我们认为，这些考虑因素解决了我们的主观印象和关于视觉能力的经验数据之间的明显冲突，同时也阐明了潜在知觉体验的表征的性质。
Although our subjective impression is of a richly detailed visual world, numerous empirical results suggest that the amount of visual information observers can perceive and remember at any given moment is limited. How can our subjective impressions be reconciled with these objective observations? Here, we answer this question by arguing that, although we see more than the handful of objects, claimed by prominent models of visual attention and working memory, we still see far less than we think we do. Taken together, we argue that these considerations resolve the apparent conflict between our subjective impressions and empirical data on visual capacity, while also illuminating the nature of the representations underlying perceptual experience.
