摘　　要：传统理论认为有限的注意资源分配给前面的靶引起随后靶的认知受损导致注意瞬脱。但新近的理论强调插入在连续靶中的干扰物在AB中的作用。该研究通过比较位于快速序列视觉呈现的数字干扰物中分别由两个字母之间插入1个数字、字母或符号构成的3种3字符在两种不同报告方式下的成绩,对TLC理论和延迟选择理论进行了检验。证明单一理论不能全面解释AB实验现象,提示AB的发生是多种机制共同作用的结果。Conventional theories of attentional blink（AB） have relied on some form of limited attentional resource that is allocated to the leading target at the expense of the trailing target. But recent theories emphasized the role of distractors intervening between successive targets. In the present study, we tested TLC and delayed selection theories by comparing the performance to three kinds of strings consisting of two target letters with one digit,one letter or one symbol inserted between them, which are embedded among rapidly presented digit distractor sequences under two different instruction conditions. The results demonstrated that not a single theory could explain all the AB phenomena in the present study, suggesting multiple mechanisms contributed to the elieitation of the AB.
