Color category influences heterogeneous visual search for color.
Many previous studies have revealed chromatic characteristics of visual search using relatively simple stimuli. They suggested that color difference between a target and distractors was a crucial factor. However, it may not be applicable to natural environments that contain numerous colors. This study demonstrates the existence of a color-category effect on heterochromatic visual search. Color ...
متن کاملColor channels, not color appearance or color categories, guide visual search for desaturated color targets.
In this article, we report that in visual search, desaturated reddish targets are much easier to find than other desaturated targets, even when perceptual differences between targets and distractors are carefully equated. Observers searched for desaturated targets among mixtures of white and saturated distractors. Reaction times were hundreds of milliseconds faster for the most effective (reddi...
متن کاملImproving Color-Difference Formulas Using Visual Data
We propose a method to improve existing color-difference formulas with additional visual data from color discrimination experiments. Color-difference formulas are treated as mean functions of Gaussian processes, and the visual data are considered as observations of these processes. Gaussian process regression is applied to predict unknown color differences. The method was evaluated with a combi...
متن کاملThe Effects of Bilingualism on Basic Color Terms in Persian
This study is to determine how bilingualism could influence the list of Persian basic color terms and their order. Using a monolingual Persian and a bilingual Kurd sample students, and a color list task, it is assumed that bilingualism could change the ordering of the non-basic color terms in the second language, but not the basic ones. Another assumption is that, the old usual methods for obta...
متن کاملThe effect of background color on asymmetries in color search.
Many previous studies have shown that background color affects the discriminability and appearance of color stimuli. However, research on visual search has not typically considered the role that the background may play. Rosenholtz (2001a) has suggested that color search asymmetries result from the relationship between the stimuli and the background. Here we test the hypothesis that background c...
