Ample evidence suggests that emotion affects visual perception. Here we asked how arousal, induced by emotional stimuli and modulated by anxiety trait, biases competition among stimuli to favor the perceptually conspicuous ones. We first demonstrated that negatively arousing pictures impaired subsequent discrimination of cars, but not the discrimination of faces, among individuals with high-trait anxiety. To directly demonstrate the role of attention in the emotional modulations of visual perception, we used a modified exogenous cuing task, showing that for anxious individuals, a negatively arousing cue elicited cost when processing cars but not faces. These results indicate that arousal biases attention toward perceptually salient stimuli, allowing those with high-trait anxiety to disengage attention from an arousing stimulus more easily when it is followed by a face. The results suggest that attention modulates the effects of emotion on perception, leading to higher resilience of high-priority stimuli to arousal-biased competition.

大量证据表明，情绪会影响视觉感知。在这里，我们想知道，情绪刺激引起的兴奋状态，以及焦虑特质的调节，如何影响刺激之间的竞争，使知觉上突出的刺激占据优势。我们首先证明，负性唤起的图片会损害高特质焦虑个体对汽车的后续辨别力，但不会损害对人脸的辨别力。为了直接证明注意力在情绪调节视觉感知中的作用，我们使用了一种改进的外源性线索任务，表明对于焦虑个体，负性唤起的线索在处理汽车时会产生成本，但在处理人脸时不会。这些结果表明，兴奋状态使注意力偏向于知觉上突出的刺激，使高特质焦虑个体在随后出现人脸时更容易将注意力从兴奋刺激中解脱出来。结果表明，注意力调节了情绪对感知的影响，使高优先级刺激对兴奋状态下竞争的抵抗力更强。（心理学文摘数据库记录（c）2019 APA，保留所有权利）。
