The attentional blink (AB) is often considered a top-down phenomenon because it is triggered by matching an initial target (T1) in a rapid serial visual presentation (RSVP) stream to a search template. However, the AB is modulated when targets are emotional, and is evoked when a task-irrelevant, emotional critical distractor (CDI) replaces T1. Neither manipulation fully captures the interplay between bottom-up and top-down attention in the AB: Valenced targets intrinsically conflate top-down and bottom-up attention. The CDI approach cannot manipulate second target (T2) valence, which is critical because valenced T2s can “break through” the AB (in the target-manipulation approach). The present research resolves this methodological challenge by indirectly measuring whether a purely bottom-up CDI can modulate report of a subsequent T2. This novel approach adds a valenced CDI to the “classic,” two-target AB. Participants viewed RSVP streams containing a T1–CDI pair preceding a variable lag to T2. If the CDI’s valence is sufficient to survive the AB, it should modulate T2 performance, indirectly signaling bottom-up capture by an emotional stimulus. Contrary to this prediction, CDI valence only affected the AB when CDIs were also extremely visually conspicuous. Thus, emotional valence alone is insufficient to modulate the AB.

注意眨眼（AB）通常被认为是自上而下的现象，因为它是通过将快速串行视觉呈现（RSVP）流中的初始目标（T1）与搜索模板匹配来触发的。但是，当目标情绪激动时，AB被调制，而与任务无关的情绪关键干扰物（CDI）替代T1时，会诱发AB。两种操作都无法完全捕捉AB中自下而上和自上而下的注意之间的相互作用：有价目标本质上将自上而下和自下而上的注意混合在一起。CDI方法无法操纵第二目标（T2）价，这很关键，因为有价的T2可以“突破” AB（在目标操纵方法中）。本研究通过间接测量是否纯净自下而上解决了这一方法论难题CDI可以调制后续T2的报告。这种新颖的方法向“经典”两目标AB中添加了价合的CDI。与会者查看了包含T1-CDI对的RSVP流，该流在T2之前有一个滞后。如果CDI的价数足以使AB存活下来，则它应该调节T2的性能，通过情绪刺激间接暗示自下而上的捕获。与此预测相反，当CDI在视觉上也非常明显时，CDI价仅影响AB。因此，仅凭情绪价不足以调节AB。
