Two experiments examined the possibility that attention directed to a distractor during rapid serial visual presentation (RSVP) can produce an attentional blink (AB). A to-be-ignored distractor (D1) preceded a target word (T2) by a variable lag in RSVP streams of black false-font distractors. D1 was highlighted by color and was a word, a string of consonants, a string of digits, or a string of false-font characters. Recall of T2 was significantly suppressed at short D1-T2 lags (the AB) but only when D1 contained letters; the AB was completely absent when D1 was composed of digits or false-font characters. Thus, the AB can be triggered by a highlighted distractor if the distractor shares features with a target.
两项实验检验了在快速序列视觉呈现(RSVP)过程中,将注意力导向一个干扰项是否会产生注意瞬脱(AB)的可能性。在由黑色伪字体干扰项组成的RSVP流中,一个待忽略的干扰项(D1)在目标词(T2)之前呈现,二者之间的延迟可变。D1通过颜色突出显示,其形式为一个单词、一串辅音字母、一串数字或一串伪字体字符。在较短的D1-T2延迟时(即注意瞬脱),T2的回忆显著受到抑制,但前提是D1包含字母;当D1由数字或伪字体字符组成时,注意瞬脱则完全不存在。因此,如果干扰项与目标具有共同特征,那么突出显示的干扰项可以触发注意瞬脱。
