在快速连续视觉呈现（RSVP）中，人们经常不能回忆起500 ms内呈现的两个视觉目标中的第二个。这种效应被称为注意力瞬脱。对注意力瞬脱的一种解释是，将第一个目标编码到记忆中的过程是缓慢的，而且容量有限。然而，在这里，我们表明，注意瞬脱应归因于注意选择，而不是巩固的第一个目标。快速序列的六个字母，观察员必须报告所有的字母（整体报告条件）或一个子集的字母（部分报告条件）。部分报告中的选择基于颜色（例如，报告两个红色字母）或身份（即，报告从特定信件开始的所有信件）。在这两种情况下，召回后不久提出的第一个选定的字母是受损的，而回忆相应的字母是相对准确的整个报告。
People often fail to recall the second of two visual targets presented within 500 ms in rapid serial visual presentation (RSVP). This effect is called the attentional blink. One explanation of the attentional blink is that processes involved in encoding the first target into memory are slow and capacity limited. Here, however, we show that the attentional blink should be ascribed to attentional selection, not consolidation of the first target. Rapid sequences of six letters were presented, and observers had to report either all the letters (whole-report condition) or a subset of the letters (partial-report condition). Selection in partial report was based on color (e.g., report the two red letters) or identity (i.e., report all letters from a particular letter onward). In both cases, recall of letters presented shortly after the first selected letter was impaired, whereas recall of the corresponding letters was relatively accurate with whole report.
