当刺激属性捕获观察者的注意力时，发生偶然注意捕获，通常与观察者对目标定义属性的自上而下的注意力设置有关。在这项研究中，我们研究了是否偶然注意捕获发生的分心，不共享的目标定义属性在物理水平上，但共享该属性在抽象层次上的表示。在快速串行视觉呈现流中，我们通过颜色来定义目标（例如，绿色的日本汉字字符）。在目标出现之前，我们提出了一个涉及目标定义颜色的干扰项（例如，表示"绿色"的白色字符）。我们观察到由分心，这是反映在确定随后的目标赤字的条件注意捕获。这一结果表明，由于注意设置，刺激扫描的基础上的目标定义属性在一个抽象的语义水平的代表。
Contingent attentional capture occurs when a stimulus property captures an observer's attention, usually related to the observer's top-down attentional set for target-defining properties. In this study, we examined whether contingent attentional capture occurs for a distractor that does not share the target-defining property at a physical level, but does share that property at an abstract level of representation. In a rapid serial visual presentation stream, we defined the target by color (e.g., a green-colored Japanese kanji character). Before the target onset, we presented a distractor that referred to the target-defining color (e.g., a white-colored character meaning "green"). We observed contingent attentional capture by the distractor, which was reflected by a deficit in identifying the subsequent target. This result suggests that because of the attentional set, stimuli were scanned on the basis of the target-defining property at an abstract semantic level of representation.
