A sentence is readily understood and recalled when presented 1 word at a time using rapid serial visual presentation (RSVP) at 10 words/s (Potter, 1984). In contrast, selecting just 2 colored letters at 10 letters/s results in easy detection of the first target but poor recall for the second when it appears 200-500 ms later. This attentional blink disappears when all letters must be reported; instead, performance drops more gradually over serial position (Nieuwenstein & Potter, 2006). Would target words in sentences escape an attentional blink? Subjects either reported 2 target words (in red or uppercase) or the whole 10-word sentence. There was a blink for Target 2 in partial report, but that target was easily remembered in whole report. With scrambled sentences whole report dropped but partial report was unaffected, again showing a blink. The attentional blink is not due to memory processing of Target 1, but to target selection, which is incompatible with sentence processing.
当使用快速序列视觉呈现(RSVP)以每秒10个单词的速度一次呈现1个单词时,句子很容易被理解和回忆(波特,1984年)。相比之下,以每秒10个字母的速度仅选择2个彩色字母,会导致第一个目标很容易被检测到,但当第二个目标在200 - 500毫秒后出现时,对其的回忆很差。当必须报告所有字母时,这种注意瞬脱现象就会消失;相反,在序列位置上表现下降得更缓慢(纽文斯坦和波特,2006年)。句子中的目标单词会避免注意瞬脱吗?受试者要么报告2个目标单词(红色或大写),要么报告整个10个单词的句子。在部分报告中,对目标2存在注意瞬脱,但在整体报告中该目标很容易被记住。对于打乱顺序的句子,整体报告下降了,但部分报告不受影响,再次显示出注意瞬脱。注意瞬脱不是由于对目标1的记忆处理,而是由于目标选择,这与句子处理不兼容。
