Two experiments assessed the effects of colored light, color of a comparison stimulus, and illumination on error in perceived depth with binocular and monocular vision. Exp. 1 assessed effects of colored light, color of comparison stimulus, and source of depth cues on error in perceived depth. A total of 29 women and 19 men, Taiwanese college or graduate students ages 20 to 30 years (M=24.0, SD= 2.5) participated; they were randomly divided into five groups, each being assigned to one of five possible colored light conditions. Analyses showed color of the comparison stimulus significantly affected the error in perceived depth, as this error was significantly greater for a red comparison stimulus than for blue and yellow comparison stimuli. Colored light significantly affected error in perceived depth since error under white and yellow light was significantly less than that under green light. Moreover, error in perceived depth under white light was significantly less than that under blue light but not sensitive to white, yellow, and red light. Error in perceived depth for binocular viewing was significantly less than that for monocular viewing but not sex. In Exp. 2, the effect of illumination on error in perceived depth was explored with 21 women and 15 men, Taiwanese college students with a mean age of 19.8 yr. (SD= 1.1). Analysis indicated that illumination significantly affected error in perceived depth, as error for a 40-W condition was significantly greater than under 20- and 60-W conditions, although the latter were not different.
两项实验评估了彩色光、比较刺激物的颜色以及照明对双眼和单眼视觉中感知深度误差的影响。实验1评估了彩色光、比较刺激物的颜色以及深度线索来源对感知深度误差的影响。共有29名女性和19名男性参与，他们是年龄在20至30岁之间的台湾大学生或研究生（M = 24.0，SD = 2.5）；他们被随机分为五组，每组被分配到五种可能的彩色光条件之一。分析表明，比较刺激物的颜色显著影响感知深度误差，因为红色比较刺激物的误差显著大于蓝色和黄色比较刺激物的误差。彩色光显著影响感知深度误差，因为白光和黄光下的误差显著小于绿光下的误差。此外，白光下的感知深度误差显著小于蓝光下的误差，但对白光、黄光和红光不敏感。双眼观察的感知深度误差显著小于单眼观察，但与性别无关。在实验2中，对21名女性和15名男性（平均年龄19.8岁，SD = 1.1的台湾大学生）探究了照明对感知深度误差的影响。分析表明，照明显著影响感知深度误差，因为40瓦条件下的误差显著大于20瓦和60瓦条件下的误差，尽管后两者没有差异。
