We have all have experienced the frustration of looking for something we want, only to find a seemingly endless series of things we do not want. This process of looking for an object of interest is called visual search. We perform visual search all the time in everyday life, because the objects we want are almost always surrounded by many other objects. But, in some cases, it takes special training to find things, such as when searching for cancers in X-rays, weapons or explosives in airport luggage, or an enemy sniper hidden in the bushes. Understanding how we search for, and find, objects we are looking for is crucial to understanding how ordinary people and experts alike operate in the real world. While much remains to be discovered, what we have learned so far offers a fascinating window into how we see.
我们都曾经历过寻找自己想要的东西时的挫败感，结果却发现了一系列看似没完没了的自己不想要的东西。这种寻找感兴趣物体的过程被称为视觉搜索。在日常生活中，我们一直在进行视觉搜索，因为我们想要的物体几乎总是被许多其他物体包围着。但是，在某些情况下，寻找东西需要特殊训练，比如在X光片中查找癌症、在机场行李中查找武器或爆炸物，或者在灌木丛中寻找隐藏的敌方狙击手。理解我们如何搜索并找到我们正在寻找的物体，对于理解普通人以及专家在现实世界中的运作方式至关重要。虽然仍有许多有待发现的地方，但我们目前所学到的知识为我们了解视觉过程提供了一扇迷人的窗口。
