空间注意转移的初步眼动研究

The First Step Primary Eye-movement Research on Spatial Shift of Attention

目的:本研究采用线运动错觉测量作为空间注意转移程度的指标,对内源性眼跳与空间注意转移的关系进行探讨。方法:被试以提示刺激的形状和颜色为线索进行相应的眼跳,通过对线运动错觉的分析探索时间间隔、眼跳位置与提示刺激空间方位一致性对空间注意转移的影响以及二者是否存在交互作用。结果:时间间隔效应显著;提示刺激位置与眼跳目标位置的空间一致性对眼跳前空间注意转移有显著影响。结论:内源性眼跳与注意的关系密切;我们可以假设注意与眼跳程序通常是相关的,但需要一个启动信号激活眼跳程序。

Objective： This study investigated whether the spatial shift of attention was involved in the process of endogenous saccades with illusory line motion that is the degree of the spatial shift of attention. Methods： Participants were instructed to saccade to the cue by the shape and color of clump, we can inspect the effect of time interval, the effect of spatial position congruence between saccade and the cue on attention shift and the interaction of them. Results： The main finding suggested： the effect of time interval is significant; the effect of spatial congruence between saccade and the cue on attention shift is significant. Conclusions： The relationship is close between endogenous saccades and attention; we could suppose that attention and saccades procedure usually be related, but needs a prime signal activation saccades prpcedure.
