摘　　要：通过去掉RSVP刺激流中第2靶(T2)之后除紧跟T2的那个干扰物之外的其他干扰物,发现了对T2的报告正确率在长间隔条件下出现了不同寻常的降低.要求两名被试积极注意整条刺激流的实验发现,AB曲线回复到常规的U形曲线.这些结果提示:RSVP刺激流中后继干扰物的去除通过使观察者的注意状态出现偏差而影响长间隔时的AB效应.The present study found that T2 report accuracy decreased to an unusual level when those distractors following T2 except the one in direct succession to it were removed.T2 accuracy of two participants recovered back to the typical U-shaped function when they are instructed to actively attend to the whole stream.These results indicate that the omission of those distractor succeeding T2 can have an influence on the AB effect at long lags by biasing the attentional status of the observers.
