情绪内容出现在目标刺激之前或之后的视觉刺激可以通过情绪注意眨眼(EAB)来阻碍对目标的有意识的知觉加工。这发生在情绪刺激之后出现的目标(前向EAB)和那些出现在情绪刺激之前的目标(回溯EAB)。此外，传统的注意眨眼(AB)的发生是因为对任何目标的检测阻碍了对后续目标的检测。本研究探讨了这些不同注意过程之间的关系。向31名男性参与者展示了快速序列的风景图像，其中偶尔有风景目标(旋转图像)。对于前向EAB，人的情绪或中性分心图像呈现在目标之前；对于回溯EAB，这些图像也是目标，呈现在景观目标之后。在后一种情况下，这种设计也允许对AB进行调查。色情和血腥图片比中性图片引起更多的EAB，但对AB没有区别的影响。这种模式很引人注目，因为虽然使用不同的目标类别(旋转的风景，人)似乎已经消除了AB，但追溯的EAB仍然存在，为情绪刺激对有意识注意力的力量提供了额外的证据。
Visual stimuli with emotional content appearing in close temporal proximity either before or after a target stimulus can hinder conscious perceptual processing of the target via an emotional attentional blink (EAB). This occurs for targets that appear after the emotional stimulus (forward EAB) and for those appearing before the emotional stimulus (retroactive EAB). Additionally, the traditional attentional blink (AB) occurs because detection of any target hinders detection of a subsequent target. The present study investigated the relations between these different attentional processes. Rapid sequences of landscape images were presented to thirty-one male participants with occasional landscape targets (rotated images). For the forward EAB, emotional or neutral distractor images of people were presented before the target; for the retroactive EAB, such images were also targets and presented after the landscape target. In the latter case, this design allowed investigation of the AB as well. Erotic and gory images caused more EABs than neutral images, but there were no differential effects on the AB. This pattern is striking because while using different target categories (rotated landscapes, people) appears to have eliminated the AB, the retroactive EAB still occurred, offering additional evidence for the power of emotional stimuli over conscious attention.
