| 摘 要： | 该研究在控制颜色视标呈现距离、颜色视标亮度的条件下，以正确率为指标，探讨了在微光环境下，颜色视标呈现时间对CRT显示器颜色视标辨别的影响作用。实验中，颜色视标的呈现时间有0．5s、1s、1．5s、3个水平。实验结果表明：在环境亮度为0．5cd/m^3的微光环境下，8种颜色视标的呈现时间对被试正确辨别颜色的绩效有明显的影响，而且呈现时间越短，被试辨别颜色绩效越差。当视标呈现时间为1．5s时，被试对8种视标的平均辨别颜色正确率达到90％以上。

| Abstract: | This experiment was conducted to investigate the time effects on the color-iden tification performance in the twilight conditions. The independent variable was the time color targets displayed range from 0.5s to 1.5s. Correct rate was analy s ed. The results showed that the time effect was significant. The color-identifi cation performance got worse when the time changed from 1.5s to 0.5s. |
