当我们不注意的时候，我们能看到什么？众所周知，当我们到其他地方去时，我们甚至可以对自然景物的主要方面“视而不见”。唯一不需要注意的任务似乎是在视觉系统的早期阶段完成的。与这种普遍的看法相反，我们报告说，受试者可以快速检测动物或车辆在简要介绍新的自然场景，同时执行另一个注意力要求高的任务。相比之下，在相同条件下，他们无法区分大T和L，或平分的双色盘与它们的镜像。我们的结论是，一些视觉任务与“高级别”的皮层区域可能会继续在附近没有注意。
What can we see when we do not pay attention? It is well known that we can be "blind" even to major aspects of natural scenes when we attend elsewhere. The only tasks that do not need attention appear to be carried out in the early stages of the visual system. Contrary to this common belief, we report that subjects can rapidly detect animals or vehicles in briefly presented novel natural scenes while simultaneously performing another attentionally demanding task. By comparison, they are unable to discriminate large T's from L's, or bisected two-color disks from their mirror images under the same conditions. We conclude that some visual tasks associated with "high-level" cortical areas may proceed in the near absence of attention.
