中国正常男青年的深度视觉阈值的测定Ⅱ

A MEASUREMENT OF THE VISUAL DEPTH DIFFERENTIAL LIMEN AMONG CHINESE MALE YOUNG PEOPLE Ⅱ

在对静态目标的深度视觉阈值测定的基础上,本文测定了中国正常男青年对一定运动速度的目标的深度视觉阈值。参加过实验(Ⅰ)的435名被试者对动态目标的深度视觉阈限是4.46弧秒(标准差为1.89弧秒)根据实验结果,这些被试者对静态目标的深度视觉阈值与对动态目标的深度视觉阈限二者有明显的正相关,并计算出?=0.29X+3.72的回归方程,二者有一定的线性关系。

The purpose of this experiment is to study the dynamic depth DL among Chinese male young people and the interrelation of static depth DL anddynamic depth DL. Active depth DL determining apparatus (controlled by electrical means)and adjusting method were again used. 435Ss attended experiment (Ⅱ). The mean of the dynamic depth DL is4.46 sec (arc), SD1.89 sec(arc). The difference between the static and dynamic depth DL is marked butthere exists positive correlation between these two. The regression equation we found is Y=0.29X+3.72.
