参与者在属于同一类别（花或蘑菇）的恐惧无关图片的网格模式阵列中搜索差异恐惧相关图片（蛇或蜘蛛），反之亦然。与恐惧相关的图片比与恐惧无关的图片更快被发现。恐惧相关，但不是恐惧无关，搜索不受显示器中目标的位置和干扰物的数量的影响，这表明平行搜索恐惧相关的目标和串行搜索恐惧无关的目标。参与者特别害怕蛇，但不是蜘蛛（反之亦然）显示出促进搜索的恐惧对象，但没有不同的控制在寻找nonfeared恐惧相关或恐惧无关，目标。因此，与进化相关的威胁性刺激在吸引注意力方面是有效的，如果刺激是情绪上的挑衅，这种效果会进一步促进。
Participants searched for discrepant fear-relevant pictures (snakes or spiders) in grid-pattern arrays of fear-irrelevant pictures belonging to the same category (flowers or mushrooms) and vice versa. Fear-relevant pictures were found more quickly than fear-irrelevant ones. Fear-relevant, but not fear-irrelevant, search was unaffected by the location of the target in the display and by the number of distractors, which suggests parallel search for fear-relevant targets and serial search for fear-irrelevant targets. Participants specifically fearful of snakes but not spiders (or vice versa) showed facilitated search for the feared objects but did not differ from controls in search for nonfeared fear-relevant or fear-irrelevant, targets. Thus, evolutionary relevant threatening stimuli were effective in capturing attention, and this effect was further facilitated if the stimulus was emotionally provocative.
