摘要 采用行为测量与ERP分析相结合的范式,以视差分离方式和线索提示有效性为自变量,考察三维空间中外源性注意定向的启动效应及其脑电机制。结果发现:短SOA下,无论是3D还是2D,非预测性边缘位置线索对后续辨认任务均发生了启动效应;3D空间中,边缘位置线索提示诱发了注意的自动定向,注意从一个深度面转移到另一深度面需要耗费一定时间;3D空间中,经典注意提示效应在ERP上表现为有效提示下P1、N1、N2等早成分的增强,跨深度空间启动效应主要应由N1的增强效应加以解释。 Employing a behavioral paradigm combined with the ERP technique, the present research is aimed at ex ploring the cueing effect of exogenous attentional o rienting on stereopsis and how it is expressed in ERP components. Main conclusions are as follows： （1） At the short SOA, the uninformative peripheral cue produced a facilitative effect on the subsequent discrimination task in both the 3D and the 2D con dition. （2） The peripheral cue elicited the automatic orientation of attention in the 3D condition, and it took time to shift attention from one depth plane to another. （3） The classic attention cueing effect provoked by the peripheral cue in stereoscopic space affected P1, N1 and N2 wave of ERP early compo nents; The crossdepth cueing effect might be ex plained by N1 enhancement.
