Identification of a second target is often impaired by the requirement to process a prior target in a rapid serial visual presentation (RSVP). This is termed the attentional blink. Even when the first target is task irrelevant an attentional blink may occur providing this first target shares similar features with the second target (contingent capture). An RSVP experiment was undertaken to assess whether this first target can still cause an attentional blink when it did not require a response and did not share any features with the following target. The results revealed that such task-irrelevant targets can induce an attentional blink providing that they were task relevant on a previous block of trials. This suggests that irrelevant focal stimuli can distract attention on the basis of a previous attentional set.
在快速序列视觉呈现（RSVP）中，由于需要处理先前的目标，识别第二个目标常常会受到干扰。这被称为注意瞬脱。即使第一个目标与任务无关，但只要它与第二个目标具有相似特征（偶然捕获），就可能会出现注意瞬脱。进行了一项RSVP实验，以评估当第一个目标不需要做出反应且与后续目标没有任何共同特征时，它是否仍然会引起注意瞬脱。结果表明，这些与任务无关的目标只要在之前的试验块中与任务相关，就能够诱发注意瞬脱。这表明无关的焦点刺激可以基于先前的注意定势分散注意力。
