注意瞬脱（AB）的输入控制理论认为，这种缺陷是由后目标1（T1）干扰引起的注意选择受损造成的。因此，当目标之间没有干扰物时，不应存在AB。与这些假设相反，观察到AB（T3赤字）时，三个目标，从同一个注意力集中，先后在一个快速流的干扰，如果受试者增加资源投入到T1处理，结果与资源枯竭帐户的AB一致。然而，Olivers等人（这个问题）认为Dux等人' T1和T2之间的关系比T1和T3之间的关系更能解释T1和T2之间的关系，以及目标区分效应。在这里，我们发现，操纵的资源主题致力于T1，无论是外源性（目标感知显着性）或内源性（目标任务相关性），影响T3的性能，即使控制T2和目标的可辨别性差异。这些结果支持Dux et al.的结论，T1资源枯竭的基础AB。
Input-control theories of the attentional blink (AB) suggest that this deficit results from impaired attentional selection caused by the post-Target 1 (T1) distractor. Accordingly, there should be no AB when there are no intervening distractors between the targets. Contrary to these hypotheses, observed an AB (T3 deficit) when three targets, from the same attentional set, were presented successively in a rapid stream of distractors if subjects increased the resources devoted to T1 processing, a result consistent with resource depletion accounts of the AB. However, Olivers et al. (this issue) argue that Dux et al.’s results can be better explained by the relationship between T1 and T2 rather than between T1 and T3, and by target discriminability effects. Here, we find that manipulating the resources subjects devote to T1, either exogenously (target perceptual salience) or endogenously (target task-relevance), affects T3 performance even when controlling for T2 and target discriminability differences. These results support Dux et al.’s conclusion that T1 resource depletion underlies the AB.
