通过三个实验 ,研究了注意瞬脱效应以便深入理解注意时间维度上的特性。实验一针对注意瞬脱效应(简称AB效应 )和刺激持续显示时间 (简称ED)之间的关系 ,发现SOA或者ED的延长能减小AB效应。实验二的结果再次证明ED的延长能减小AB效应 ,并且发现ED延长并没有伴随着对目标的加工速度的加快。实验三发现在目标与干扰项没有显著的特征差异时 ,AB效应随着ED延长而减小的现象消失了 ,即ED对AB效应的影响出现了实验性的分离。同时还证明突出显示可以通过加快对目标的反应速度来显著的减小AB效应 ,而且ED因素只有在目标具有突出的视觉特征时才能改变AB效应。

Three experiments focused on the relationship between the exposure duration( ED) and the Attentional Blink(AB) . It was found in the first experiment that the magnitude of AB trailed off as the ED become longer. The SOA had similar effect on the AB as the ED had and the interactive effect between SOA and ED is significant either. The second experiment replicated the result pattern of the experiment one and indicate that the ED effect found in forenamed experiments is not caused by speed - up response to the Target . The experimental dissociation of the ED effect - - weakening AB effect as ED prolonged disappeared - -
was found in the third experiment and is proved to be caused by the enhanced distracters as their ED prolonged when targets anddistracters share similar preattentive features. Moreover , it was evident that visual salience can accelerate the speed of processing information by guiding the attentive process to the target and finally result in weakened AB effect . The Central Interference Theory should be modified to accommodate to the result of the experiments.
