Color Categorical Perception
Categorical perception (CP) occurs when discrimination of items that cross category boundaries is faster or more accurate than discrimination of exemplars from the same category. Categorical perception of color is observed when, for example, a green stimulus and a blue stimulus are more easily distinguished than two stimuli from the same color category (e.g., two different shades of green). Col...

متن کاملRunning head: CATEGORICAL PERCEPTION OF COLOR Neurophysiological Evidence for Categorical Perception of Color
The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within-and between-category stimuli equated in Munse...
متن کاملRunning Head: ERP CATEGORICAL COLOR PERCEPTION Color Categories Affect Pre-Attentive Color Perception
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 ...
متن کاملCategorical perception reflects non-basic color categories
Categories can affect our perception of the world, rendering between-category differences more salient than withincategory ones — a phenomenon known as categorical perception (CP). Previous research has shown that basic color categories across a variety of languages yield CP in speakers of those languages. Here, we provide evidence that CP generalizes to color categories beyond the basic level....
