The attentional blink (AB) and repetition blindness (RB) phenomena refer to subjects' impaired ability to detect the second of two different (AB) or identical (RB) target stimuli in a rapid serial visual presentation stream if they appear within 500 msec of one another. Despite the fact that the AB reveals a failure of conscious visual perception, it is at least partly due to limitations at central stages of information processing. Do all attentional limits to conscious perception have their locus at this central bottleneck? To address this question, here we investigated whether RB is affected by online response selection, a cognitive operation that requires central processing. The results indicate that, unlike the AB, RB does not result from central resource limitations. Evidently, temporal attentional limits to conscious perception can occur at multiple stages of information processing.
注意瞬脱（AB）和重复盲视（RB）现象是指在快速序列视觉呈现流中，如果两个不同（AB）或相同（RB）的目标刺激彼此在500毫秒内出现，被试检测第二个目标刺激的能力受损。尽管注意瞬脱揭示了有意识视觉感知的失败，但它至少部分是由于信息处理中枢阶段的局限性所致。有意识感知的所有注意限制都位于这个中枢瓶颈处吗？为了解决这个问题，我们在此研究了重复盲视是否受到在线反应选择的影响，在线反应选择是一种需要中枢处理的认知操作。结果表明，与注意瞬脱不同，重复盲视并非由中枢资源限制导致。显然，有意识感知的时间注意限制可能发生在信息处理的多个阶段。
