Resumen: | Although the spectral saturation discrimination function has been well documented for young observers, it has not been systematically investigated as a function of age. Kraft and Werner demonstrates significant age-related losses in colorimetric purity discrimination sensitivity. The differences between discrimination at 10 and 250 td was relatively small for the younger group but larger for the older group, indicating a selective performance decrement for older observers at low light levels. We talk about simultaneous color matching when this takes place between juxtaposed color samples and the gap time is zero. Successive, or memory, color matching takes place when we make comparisons between color stimuli separated by time, trying to match a present color to a memorized one, which obliges us to use memory. There is a lot of research related to color in memory. The aim of this work is to study the effect of age changes on chroma of 5 reference tests, using the methods of simultaneous and memory color matching. |
