Newly trained lexical categories produce lateralized categorical perception of color.
Linguistic categories have been shown to influence perceptual discrimination, to do so preferentially in the right visual field, to fail to do so when competing demands are made on verbal memory, and to vary with the color-term boundaries of different languages. However, because there are strong commonalities across languages in the placement of color-term boundaries, the question remains open ...
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....
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 کاملColor 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 کاملElectrophysiological evidence for the left-lateralized effect of language on preattentive categorical perception of color.
Previous studies have shown that the effect of language on categorical perception of color is stronger when stimuli are presented in the right visual field than in the left. To examine whether this lateralized effect occurs preattentively at an early stage of processing, we monitored the visual mismatch negativity, which is a component of the event-related potential of the brain to an unfamilia...
