Color categories and color appearance.
We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not ...
متن کاملVisual structures for achromatic color perceptions.
Accuracy of achromatic perceptions (correctly seeing blacks, grays, and whites) was investigated for three-dimensional rooms, painted matte black or white, presented empty or containing matte or specular, and black, middle gray, or white objects. The rooms were illuminated by a point source at various locations or by extended sources. Observers judged the achromatic color of four walls in the r...

1. Challenges to the Universals and Evolution theory of basic color term naming A theory of basic color term meanings based on the observation of semantic universals and evolutionary regularity in the naming of colors across languages was proposed by Berlin and Kay (1969). This model has undergone numerous revisions. I will refer to the various versions collectively as the UE model. A constant ...
متن کاملInfant Color Categories
Although humans can discriminate millions of colors, language typically refers to color using a limited number of discrete categories (e.g., red, green, blue). Color categories are not only present in language (color terms), they are also present in “thought.” For example, at least under some circumstances, adults’ perceptual or cognitive judgments of color (e.g., color memory, search, or simil...
متن کاملComparative Color Categories
The entire range of human color perception, in all its vibrancy, is due to the operation of just three types of photosensitive retinal cone cells and the neural mechanisms responsible for interpreting their signals. These cone cells contain photosensitive opsin pigments that preferentially absorb light at different wavelengths. The short-wavelength (S) pigment has peak absorption of light at ab...
