This article reviews recent work on the perception of color in cases where color change leads to scission, or a perceived layering in depth of the visual field into chromatic processes. A model is proposed that predicts under what circumstances a layering in depth is perceived. The model takes into account shift in color and change in contrast; it helps to describe the colors and lightnesses of...

Color perception can be categorical: Between-category discriminations are more accurate than equivalent within-category discriminations. The effects could be inherited, learned, or both. The authors provide evidence that supports the possibility of learned categorical perception (CP). Experiment 1 demonstrated that observers' color discrimination is flexible and improves through repeated practi...

Categorical perception (CP) of color is the faster and/or more accurate discrimination of colors from different categories than equivalently spaced colors from the same category. Here, we investigate whether color CP at early stages of chromatic processing is independent of top-down modulation from attention. A visual oddball task was employed where frequent and infrequent colored stimuli were ...

We know most about the sense of Sight, with milestones like Berlin & Kay (1969) and Kay et al. (2006). Languages differ in quite systematic ways in their expression of color terms that can be related to basic mechanisms of color perception and the further neural processing of visual stimuli. We can distinguish between a pair of terms denoting intensity (light and dark), and terms denoting indiv...

Early visual experience is indispensable to shape the maturation of cortical circuits during development. Monocular deprivation in infancy, for instance, leads to an irreversible reduction of visually driven activity in the visual cortex through the deprived eye and a loss of binocular depth perception. It was tested whether or not early experience is also necessary for color perception. Infant...

We introduce and explore a color phenomenon which requires the prior perception of motion to produce a spread of color over a region defined by motion. We call this motion-induced spread of color dynamic color spreading. The perception of dynamic color spreading is yoked to the perception of apparent motion: As the ratings of perceived motion increase, the ratings of color spreading increase. T...

The paper examines the formation of color categories and color terms in a population of autonomous individuals, i.e. simulated agents. Each agent is modeled to perceive color stimuli, to categorize the stimuli and to lexicalize the categories in order to communicate with other agents in the population. During these interactions the agents adapt their internal representations to be more successf...

Traditional color vision theory posits that three types of retinal photopigments transduce light into a trivariate neural color code, thereby explaining color-matching behaviors. This principle of trichromacy is in need of reexamination in view of molecular genetics results suggesting that a substantial percentage of women possess more than three classes of retinal photopigments. At issue is th...

The perceived color of an object depends on the chromaticity of its immediate background. But color appearance is also influenced by remote chromaticities. To quantify these influences, the effects of remote color fields on the appearance of a fixated 2 degrees test field were measured using a forced-choice method. Changes in the appearance of the test field were induced by chromaticity changes...
