情感刺激往往比非情感刺激更能吸引和吸引注意力。研究发现，令人厌恶的图片即使在情绪信息消失后也会损害对视觉目标的感知。这种相互关联的情绪和注意力系统的好处有时会在进化框架内进行讨论，生存优势归因于及早发现威胁刺激。然而，与最近的建议一致的是，无论是积极的还是消极的刺激，人们的注意力都会被吸引到唤起的刺激上，目前的调查发现，性爱分心--通常被评为愉悦和唤醒--总是会引起一种与令人厌恶的分心因素引起的暂时性“情绪诱导失明”类似的症状(实验1)。这种效应持续存在，尽管基于绩效的金钱激励使其忽略分心因素(实验2)，并且注意操作减少了厌恶图像的干扰(实验3)。研究结果表明，积极的刺激可以自发地导致情绪诱发的视觉处理缺陷，就像厌恶的刺激一样。
Emotional stimuli tend to capture and hold attention more than non-emotional stimuli do. Aversive pictures have been found to impair perception of visual targets even after the emotional information has disappeared. The benefits of such interlinked emotion and attention systems have sometimes been discussed within an evolutionary framework, with a survival advantage attributed to early detection of threatening stimuli. However, consistent with recent suggestions that attention is drawn to arousing stimuli regardless of whether they are positive or negative, the current investigation found that erotic distractors-generally rated as both pleasing and arousing-consistently elicited a transient "emotion-induced blindness" similar to that caused by aversive distractors (Experiment 1). This effect persisted despite performance-based monetary incentives to ignore the distractors (Experiment 2), and following attentional manipulations that reduced interference from aversive images (Experiment 3). The findings indicate that positively arousing stimuli can spontaneously cause emotion-induced deficits in visual processing, just as aversive stimuli can.
