我们调查了注意力瞬脱(AB)的大小是否与分心抑制失败有关。受试者观看了双目标快速连续视觉呈现(RSVP)流，其中直接在目标2(T2-1，T2+1)之前和之后的干扰物彼此相同或不同。此前，Dux、Coltheart和Harris(2006)在RSVP中发现，由于目标1周围的干扰物重复，目标报告增强，这被解释为干扰物抑制的证据。在这里，分心重复再次减弱了AB，但只在滞后2，目标2的位置，T2-1将在那里进行专心加工。我们的结果表明，分心物重复效应依赖于注意力，而抑制分心物的失败导致了AB。
We investigated whether a failure of distractor inhibition contributes to the magnitude of the attentional blink (AB). Subjects viewed dual-target rapid serial visual presentation (RSVP) streams, where the distractors that directly preceded and succeeded Target 2 (T2-1, T2+1) were either identical to each other or different. Previously, Dux, Coltheart, and Harris (2006) found enhanced target report in RSVP due to repetition of distractors around Target 1, which was interpreted as evidence of distractor inhibition. Here, distractor repetition again attenuated the AB, but only at lag 2, the Target 2 position where T2-1 would have undergone attentive processing. Our results demonstrate that the distractor repetition effect is dependent on attention, and that a failure to inhibit distractors contributes to the AB.
