威胁信息已被证明可以吸引注意力并增强感官处理。最近的证据还表明，接触可怕的刺激可能会增强对随后呈现的信息的感知处理，并提高注意力能力。然而，这些结果与其他发现不一致，即恐惧刺激会减少与任务无关的分心并提高选择性注意力。在这里，我们研究了之前接触恐惧面孔对埃里克森侧翼任务表现的影响。在实验中，与其他情绪表达和倒置的面部物品相比，在注意力负荷的情况下，恐惧暗示会导致视觉空间中放置的物品与任务无关的干扰增加。研究结果支持这样一种观点，即可怕的图像可以增强注意力，使人们在暗示危险时能够注意到尽可能多的视觉信息。讨论了关于恐惧和选择性注意的影响的相互矛盾的发现。
Threatening information has been shown to both capture attention and enhance sensory processing. Recent evidence has also suggested that exposure to fearful stimuli may enhance perceptual processing of subsequently presented information, as well as increase attentional capacity. However, these results are inconsistent with other findings that fearful stimuli reduce task-irrelevant distraction and improve selective attention. Here, we investigated the effect of prior exposure to fearful faces on performance in the Eriksen flanker task. Across experiments, fearful cues led to increased task-irrelevant distraction for items positioned across visual space, in contrast to other emotional expressions and inverted face items, and under conditions of attentional load. Findings support the view that fearful images enhance attentional capacity, allowing one to attend to as much visual information as possible when danger is implied. Conflicting findings on the effect of fear and selective attention are discussed.
