When 2 targets are presented among distractors in rapid serial visual presentation, correct identification of the 1st target results in a deficit for a 2nd target appearing within 200-500 ms. This attentional blink (AB; J.E. Raymond, K.L. Shapiro, & K.M. Arnell, 1992) was examined for categorically defined targets (letters among nonletters) in 7 experiments. AB was obtained for the 2nd letter target among digit distractors (Experiment 1) and also for a 3rd target (Experiment 2). Results of Experiments 3-5 confirmed that AB is triggered by local interference from immediate posttarget stimulation (Raymond et al., 1992) and showed that AB is modulated by the discriminability between the 1st target and the immediately following distractor. Experiments 5-7 further examined the effects of both local interference and global discriminability. A 2-stage model is proposed to account for the AB results.
当在快速序列视觉呈现中于干扰项中呈现两个目标时，正确识别第一个目标会导致在200 - 500毫秒内出现的第二个目标的识别能力下降。在7个实验中，针对按类别定义的目标（非字母中的字母）对这种注意瞬脱（AB；J.E. 雷蒙德、K.L. 夏皮罗和K.M. 阿内尔，1992）进行了研究。在数字干扰项中，第二个字母目标出现了注意瞬脱（实验1），第三个目标也出现了注意瞬脱（实验2）。实验3 - 5的结果证实，注意瞬脱是由目标后即刻刺激的局部干扰引发的（雷蒙德等人，1992），并表明注意瞬脱受到第一个目标与紧随其后的干扰项之间可辨别性的调节。实验5 - 7进一步研究了局部干扰和全局可辨别性的影响。提出了一个两阶段模型来解释注意瞬脱的结果。
