Models of the attentional blink phenomenon (AB) typically assume that unattended information is processed to the post-perceptual level prior to selection for access to consciousness. The present experiments test this assumption by manipulating the perceptual load of the first target task (T1) and whether the second target (T2) was the participant's own name or someone else's name. In three experiments, increasing T1-load increased the severity of the AB for personal names. The results suggest that selection during the AB is not fixed at the post-perceptual stage, but rather the stage at which selection occurs during the AB is flexible.
注意瞬脱现象(AB)的模型通常假定,未被注意的信息在被选择进入意识之前会被加工到知觉后水平。本实验通过操纵第一个目标任务(T1)的知觉负载以及第二个目标(T2)是参与者自己的名字还是别人的名字来检验这一假设。在三个实验中,增加T1负载会增加对人名的AB严重程度。结果表明,AB过程中的选择并非固定在知觉后阶段,而是AB过程中选择发生的阶段是灵活的。
