摘要
该研究以正确率为指标 ,研究微光环境下CRT显示器颜色视标辨别的面积效应。实验中颜色视标面积直径有 1.5mm、8mm、14mm3个水平。实验结果表明 :在环境亮度为 0 .5cd/m2 的微光环境下 ,不同颜色视标面积对被试正确辨别颜色绩效有显著影响 ,并且颜色视标面积越大 ,被试辨别颜色正确率也越高。
An experiment was conducted to investigate the area effects on the color-identification performance in the twilight conditions. The independent variable was the area of color targets whose diameters range from 1.5mm to 14mm. Correct rate was analysed. The results showed that the area effect of color targets was significant. The color-identification performance got better when the diameters of color targets changed from 1.5mm to 14mm.
