整体运动知觉检测方法的设计

The design of global motion perception testing method

目的设计整体运动知觉检测方法和研究正常人运动知觉特性。方法设计整体运动知觉测试软件,由微机控制,测定20例(40眼)正常人的运动知觉阈值。结果正常人运动知觉功能与性别及眼别无相关关系,而大于与小于50岁组的运动知觉分数值分别为4.47±0.40、4.85±0.16,两者具有显著性差异。结论建立了整体运动知觉检测方法,为临床应用打下了基础。

Objective To design global motion perception(MP) testing method and to study the characteristics of motion perception in normal subjects. Methods The software of random dots motion testing was designed . MP from 20 cases(40 eyes)normal subjects were tested by moving random dots stimulus displayed on the noise-background and used to measure the motion threshold. Result There were no relationships between either MP and sex or MP and eye sides difference. MP from old and young groups were 4.47±0.40, 4.85±0.16 respectively and there was significant difference between them. Conclusion The global motion perception testing method is designed and might be helpful for further clinical using.
