注意捕获是视觉空间注意力无意识地转移到高度显著或与当前任务集相关的干扰物位置的过程。后一种情况被称为偶然捕获，因为效果取决于刺激的特征与观看者的任务定义的注意力控制设置之间的匹配。条件捕获已被证明是低级别的功能，如颜色，运动和方向。在本文中，我们表明，偶然捕获也可以发生在上级水平的概念信息（例如，运动器材、海洋动物、甜点食品）。这种效应迅速发生（即，在200毫秒内），是注意力的一种空间形式，并且取决于在每次试验中改变的注意力控制设置，这表明自然图像可以被解码成它们的概念意义，以在单个注视的时间过程内驱动注意力的转移。
Attentional capture is an unintentional shift of visuospatial attention to the location of a distractor that is either highly salient, or relevant to the current task set. The latter situation is referred to as contingent capture, in that the effect is contingent on a match between characteristics of the stimuli and the task-defined attentional-control settings of the viewer. Contingent capture has been demonstrated for low-level features, such as color, motion, and orientation. In the present paper we show that contingent capture can also occur for conceptual information at the superordinate level (e.g., sports equipment, marine animal, dessert food). This effect occurs rapidly (i.e., within 200 ms), is a spatial form of attention, and is contingent on attentional-control settings that change on each trial, suggesting that natural images can be decoded into their conceptual meaning to drive shifts of attention within the time course of a single fixation.
