在七个实验中，观察者在正常物体中寻找一个混乱的物体。关键的比较是在重复搜索和不重复条件之间进行的，在重复搜索中，同一组刺激在许多（> 100）试验中保持在显示器的固定位置，在不重复条件下，每次试验都呈现新的刺激。在反复搜索的情况下，观察员监测到一个基本稳定的显示，一个清晰可见的物体被破坏。这是重复搜索实验的延伸，在重复搜索实验中，受试者在每次试验中搜索一组固定的项目以寻找不同的目标（Wolfe，Klempen，& Dahlen，2000），并且可以被认为是“变化盲视”任务的一种形式。不重复的搜索是非常低效的，这表明一个杂乱的对象不会在完整的对象中“弹出”（反之亦然）。有趣的是，重复搜索条件同样效率低下，就好像参与者即使在对特定场景的特定变化有了丰富的经验之后，也必须搜索混乱的目标。结果表明，在一个新的场景中搜索目标所涉及的注意过程可能是非常相似的，用于确认目标的存在，在一个熟悉的场景。
In seven experiments, observers searched for a scrambled object among normal objects. The critical comparison was between repeated search in which the same set of stimuli remained present in fixed positions in the display for many (> 100) trials and unrepeated conditions in which new stimuli were presented on each trial. In repeated search conditions, observers monitored an essentially stable display for the disruption of a clearly visible object. This is an extension of repeated search experiments in which subjects search a fixed set of items for different targets on each trial (Wolfe, Klempen, & Dahlen, 2000) and can be considered as a form of a “change blindness” task. The unrepeated search was very inefficient, showing that a scrambled object does not “pop-out” among intact objects (or vice versa). Interestingly, the repeated search condition was just as inefficient, as if participants had to search for the scrambled target even after extensive experience with the specific change in the specific scene. The results suggest that the attentional processes involved in searching for a target in a novel scene may be very similar to those used to confirm the presence of a target in a familiar scene.
