在提前查看一些干扰项后，视觉搜索会更容易，因为预览的干扰项不会被搜索到(预览好处)。预览好处的一个主要解释是，它是由于旧对象(视觉标记)的抑制而发生的。然而，另一种观点认为，预览的好处只是反映了对新对象的自动注意定向(开始捕获)。为了解决视觉标记除了开始捕获之外是否还起作用的问题，我们比较了总是以新项出现的目标的搜索性能(“标记”条件)和以新项或旧项同等出现的目标的搜索性能(“捕获”条件)。当项目呈现在一个看不见的矩阵中的任意位置时，“标记”条件下的斜率比“捕捉”条件下的要浅，有利于视觉标记的参与(实验1和实验2)。相反，当项目沿圆周排列时，搜索条件之间的斜率没有差异，而不考虑旧项目的变化(实验3)。这些发现表明，视觉标记的贡献取决于搜索项目的配置；对于复杂的显示，对新对象的优先选择与对旧对象的取消优先选择相结合会更有效。(C)2016爱思唯尔有限公司。保留所有权利。
Visual search is easier after looking at some distractors in advance because previewed distractors are excluded from the search (preview benefit). A dominant explanation for preview benefit is that it occurs because of the inhibition of old objects (visual marking). However, another view claims that preview benefit simply reflects automatic attentional orienting to new objects (onset capture). To address the question of whether visual marking plays any role in addition to onset capture, we compared the search performance for a target that always appeared as a new item ("marking" condition) with the performance for a target that appeared equally as a new or old item ("capture" condition). When items were presented at random positions in an invisible matrix, the slope in the "marking" condition was shallower than that in the "capture" condition, favoring the involvement of visual marking (Experiments 1 and 2). In contrast, no difference in slope was found among the search conditions regardless of changes in old items when items were arranged around the circumference of a circle (Experiment 3). These findings suggest that the contribution of visual marking depends on the configuration of search items; with complex displays, prioritizing selection for new objects is more effective if coupled with de-prioritizing de-selection for old objects.
