当 2 个视觉目标中的第 2 个（第一个目标 [T1] 和第二个目标 [T2]）在时间上紧密呈现时，观察者经常会错过这些目标；注意眨眼（AB）。作者推测，AB 的发生是因为 T1 处理延迟了对 T2 的注意力反应，导致 T2 失去了对其后面项目的注意力竞争。作者通过确定 T2 提前时 AB 是否减弱来研究这一假设。 4个实验的结果表明，当T2提前时，AB的持续时间和幅度显着减少。在 T2 报告中观察到的改进并不是以牺牲 T1 报告为代价而发生的，这表明当提示出现时，T1 的处理已经完成或至少受到保护。作者得出的结论是，在 AB 期间，检测和选择用于巩固短期记忆的候选目标之间存在延迟。
Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that follows it. The authors investigated this hypothesis by determining whether the AB is attenuated when T2 is precued. The results from 4 experiments showed that the duration and magnitude of the AB were substantially reduced when T2 was precued. The observed improvement in T2 report did not occur at the expense of T l report, suggesting that processing of T I was already completed or was at least protected when the cue was presented. The authors conclude that, during the AB, there is a delay between detection and the selection of target candidates for consolidation in short-term memory.
