Abstract: In this paper, perceptual discriminations of twelve colors and twelvefigures were studied for 3--6 year old children. Three exposure timesfor each color and each figure were used in the experiments, i. e. 0.01 sec,0.05 sec, and 0.1 sec in random order. From the results, it is seen thatthere are significant influences of the exposure time on color and figurediscrimination. The effect of exposure time on figure discrimination wasmore pronounced for younger children. The ability of color and figurediscrimination of 3--6 year old children increased with age stepby step. The ability of color discrimination of pre-school children, underthree exposure times, the correct discriminative percentage of yellow, red,green are the highest. The difficulties of correct discrimination of the 12figures are not the same, some are easier and some are more difficult, thesedifferences may be correlated with the spatial character of figures and thedifficulty of coding through the medium of words.
