当对干扰项中的两个目标以每项100ms的快速连续视觉呈现进行监控时，当第二个目标(T2)在第一个字母目标(T1)开始后200-500ms出现时，观众很难报告其出现：注意眨眼(AB；M.M.Chun&M.C.Potter，1995b；J.E.Raymond，K.L.Shapiro，&K.M.Arnell，1992)。听觉搜索也会出现同样的缺陷吗？比较了两种任务对听觉、视觉和跨通道目标的搜索：(A)在数字中识别2个目标字母(实验1-3和5)或在字母中识别数字(实验6)；(B)在字母中识别1个数字并确定随后的字母中是否出现X(实验4)。在使用第一个任务的实验中，只有在两个目标都是可视的情况下才能找到标准AB。在第二个任务中，当选择集从T1变为T2时，无论目标通道如何，任务转换都会出现缺陷。
When monitoring a rapid serial visual presentation at 100 ms per item for 2 targets among distractors, viewers have difficulty reporting the 2nd target (T2) when it appears 200-500 ms after the onset of the 1st letter target (T1): an attentional blink (AB; M. M. Chun & M. C. Potter, 1995b; J. E. Raymond, K. L. Shapiro, & K. M. Arnell, 1992). Does the same deficit occur with auditory search? The authors compared search for auditory, visual, and cross-modal targets in 2 tasks: (a) identifying 2 target letters among digits (Experiments 1-3 and 5) or digits among letters (Experiment 6), and (b) identifying 1 digit among letters and deciding whether an X occurred among the subsequent letters (Experiment 4). In the experiments using the 1st task, the standard AB was found only when both targets were visual. In the 2nd task, with a change in selective set from T1 to T2, a task-switching deficit was obtained regardless of target modality.
