拓扑性质知觉的大脑半球功能不对称性研究

本文以视觉的拓扑知觉理论为指导进行大脑半球功能不对称性的研究。全文共有三个实验，考察了辨别扭扑性质差异和其它几何性质差异时大脑半球的功能不对称性．拓扑性质差异包括洞（封闭性）的差异和内外关系的差异．实验结果显示：对于右利手被试，辨别拓扑性质差异时，左半球有优势。辨别距离和朝向等几何性质差异时，右半球有优势或没有统计显著的大脑半球功能不对称性。

AN TOPOLOGICAL PERCEPTION APPROACH TO THE STUDY OF HEMISPHERIC ASYMMETRY

With an approach of topological perception, 3 setsof stimulus patterns weredesigned to investigate heml-spheric asymmetry. In topologicaldiscrirnination theright -handers demonstraded significant superiority inthe left hemisphere of the brain, but in the discrimina-tion ofgeometrical properties such as distance and ori-entation, they showedsuperiority in the right hemi-sphere or the absence of a significanthemisphericasymmetry.
