When the second of two targets is presented temporally close (within 500 ms) to the first target in rapid serial visual presentation, accuracy for reporting the second target is markedly diminished-an attentional blink (AB). The AB has become a well-studied phenomenon, and multiple different versions of the AB are currently in use. However, little is known about the stability of individual performance on the AB. The current study examined the reliability of two different versions of the AB task (a task-switch and no-task-switch version) within session, and over the period of 7-10 days, in order to examine performance stability. In addition to testing the reliability, we also examined the relationship between both versions of our AB tasks. Both versions of the AB were shown to be reliable within session, and over time, suggesting that performance is quite stable on this task. In addition, performance on the two different AB tasks was significantly correlated within and across sessions, suggesting that the AB phenomenon is being accurately captured by versions of the AB that include a task-switch. These findings are important given the recent interest in individual differences in performance on the AB.
当两个目标中的第二个在快速连续视觉呈现中时间上接近（500 毫秒内）第一个目标时，报告第二个目标的准确性明显降低——这就是注意力眨眼（AB）现象。AB 已经成为一个研究得很好的现象，目前有多种不同版本的 AB 在使用。然而，关于个体在 AB 上的表现稳定性知之甚少。本研究在一个会话内以及 7-10 天的时间内，分别检查了 AB 任务的两种不同版本（任务切换和非任务切换版本）的可靠性，以检查性能的稳定性。除了测试可靠性之外，我们还研究了我们的 AB 任务的两种版本之间的关系。AB 的两种版本在会话内和随时间都表现出可靠，这表明在这个任务上的表现相当稳定。此外，两种不同的 AB 任务的表现在内和跨会话都显著相关，这表明包括任务切换的 AB 版本准确地捕捉到了 AB 现象。鉴于最近对 AB 表现的个体差异的兴趣，这些发现非常重要。
