如果两个目标中的第二个目标在第一个目标出现后不到 500 毫秒内出现，那么对第二个目标的识别就会受到影响。这种第二目标缺陷的理论解释被称为注意力眨眼（AB），依赖于某种形式的有限注意力资源，该资源被分配给领先目标，而牺牲了落后目标。本研究中的三个实验表明，当目标由属于同一类别（例如字母或数字）的三个项目组成的流时，资源限制帐户无法解释为什么 AB 不存在。但是，如果目标字符串中插入了不同类别的项目，则 AB 会恢复。这一结果以及 AB 文献中的所有主要结果都可以通过以下假设来解释：AB 是由于暂时失去对普遍注意力集的控制而产生的。这种控制失误使得观察者很容易受到外源触发的注意力转移的影响。
Identification of the second of two targets is impaired if it is presented less than about 500 ms after the first. Theoretical accounts of this second-target deficit, known as attentional blink (AB), have relied on some form of limited attentional resource that is allocated to the leading target at the expense of the trailing target. Three experiments in the present study reveal a failure of resource-limitation accounts to explain why the AB is absent when the targets consist of a stream of three items belonging to the same category (e.g., letters or digits). The AB is reinstated, however, if an item from a different category is inserted in the target string. This result, and all major results in the AB literature, is explained by the hypothesis that the AB arises from a temporary loss of control over the prevailing attentional set. This lapse in control renders the observer vulnerable to an exogenously-triggered switch in attentional set.
