This early deviance-related negativity was defined as the vMMN, parallel to mismatch negativity (MMN) in auditory stimuli and to vMMN in other visual stimuli (27,32,33). The vMMN was maximal over the lateral parietal-occipital scalp; so electrodes O1, O2, PO7, PO8, PO3, PO4, P5, P6, P7, and P8 were chosen for further analysis.…”

“…This finding suggests that the use of lexical information in the left hemisphere is the origin of differential visual hemifield responses to color stimuli (14)(15)(16)(17)(18)(19)(20)(21)(22)(23). There has been some suggestion that the left cerebral hemispheric areas implicated in important language functions may serve as a top-down control source that modulates the activity level of the visual cortex (24)(25)(26)(27)(28), but little is known about whether this lateralized effect occurs at early, preattentive perceptual processing stages or at postperceptual decision/response phases. Visual mismatch negativity (vMMN) is widely held to reflect the brain's early and automatic change in event-related potentials (ERPs) in response to a novel stimulus (29)(30)(31).…”

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 unfamiliar stimulus among a temporally presented series of stimuli. In the oddball paradigm we used, the deviant stimuli were unrelated to the explicit task. A significant interaction between color-pair type (within-category vs. between-category) and visual field (left vs. right) was found. The amplitude of the visual mismatch negativity component evoked by the within-category deviant was significantly smaller than that evoked by the between-category deviant when displayed in the right visual field, but no such difference was observed for the left visual field. This result constitutes electroencephalographic evidence that the lateralized Whorf effect per se occurs out of awareness and at an early stage of processing.lateralization | Whorfian B ehavioral, electrophysiological, and neuroimaging studies have shown that early processing of color stimuli can be affected by the categories encoded in the language of the observer (1-13). More recently, this "Whorfian" effect in color processing has been demonstrated to be stronger for stimuli exposed in the right visual field (RVF) than in the left visual field (LVF) and to disappear in the presence of a concurrent demand on verbal memory. This finding suggests that the use of lexical information in the left hemisphere is the origin of differential visual hemifield responses to color stimuli (14-23). There has been some suggestion that the left cerebral hemispheric areas implicated in important language functions may serve as a top-down control source that modulates the activity level of the visual cortex (24-28), but little is known about whether this lateralized effect occurs at early, preattentive perceptual processing stages or at postperceptual decision/response phases. Visual mismatch negativity (vMMN) is widely held to reflect the brain's early and automatic change in event-related potentials (ERPs) in response to a novel stimulus (29)(30)(31). In the present study, the vMMN component is observed in order to assess the lateralized Whorfian response to task-irrelevant changes in color stimuli. There have been several related studies in this area, however. Thierry and associates (25,26) showed in nonlateralized studies with task-irrelevant responses that Greek speakers' vMMN components, starting around 100 ms poststimulus, peaking around 200 ms, and maximal over parietooccipital scalp areas, show sensitivity to the basic lexical distinction in the Greek language between light and dark blue, whereas English speakers show no such effect.

“…The origin and nature of such color categories has been extensively debated across the cognitive sciences (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Traditionally, debate has focused on whether color categories are biologically constrained (2,3), or whether they are arbitrary linguistic constructs that arise out of culture and communication (4).…”

“…Also debated is the extent to which color categories affect how color is perceived. Some have argued that color categories affect the cognitive or attentional strategies of perceptual color judgments (7,8), or that color categories affect early stages of color processing even when colors are not attended (9)(10)(11)(12). However, others have argued that noncategorical sensory models of color encoding are sufficient to account for how color is perceived (13).…”

The areas of the brain that encode color categorically have not yet been reliably identified. Here, we used functional MRI adaptation to identify neuronal populations that represent color categories irrespective of metric differences in color. Two colors were successively presented within a block of trials. The two colors were either from the same or different categories (e.g., "blue 1 and blue 2" or "blue 1 and green 1"), and the size of the hue difference was varied. Participants performed a target detection task unrelated to the difference in color. In the middle frontal gyrus of both hemispheres and to a lesser extent, the cerebellum, blood-oxygen level-dependent response was greater for colors from different categories relative to colors from the same category. Importantly, activation in these regions was not modulated by the size of the hue difference, suggesting that neurons in these regions represent color categorically, regardless of metric color difference. Representational similarity analyses, which investigated the similarity of the pattern of activity across local groups of voxels, identified other regions of the brain (including the visual cortex), which responded to metric but not categorical color differences. Therefore, categorical and metric hue differences appear to be coded in qualitatively different ways and in different brain regions. These findings have implications for the long-standing debate on the origin and nature of color categories, and also further our understanding of how color is processed by the brain.categorization | functional magnetic resonance imaging | chromatic
