Hue Cancellation

Psychophysical studies suggest that different colors have different perceptual status: red and blue for example are thought of as elementary sensations whereas yellowish green is not. The dominant account for such perceptual asymmetries attributes them to specificities of the neuronal representation of colors. Alternative accounts involve cultural or linguistic arguments. What these accounts have in common is the idea that there are no asymmetries in the physics of light and surfaces that could underlie the perceptual structure of colors, and this is why neuronal or cultural processes must be invoked as the essential underlying mechanisms that structure color perception. Here, we suggest a biological approach for surface reflection properties that takes into account only the information about light that is accessible to an organism given the photopigments it possesses, and we show that now asymmetries appear in the behavior of surfaces with respect to light. These asymmetries provide a classification of surface properties that turns out to be identical to the one observed in linguistic color categorization across numerous cultures, as pinned down by cross cultural studies. Further, we show that data from psychophysical studies about unique hues and hue cancellation are consistent with the viewpoint that stimuli reported by observers as special are those associated with this singularity-based categorization of surfaces under a standard illuminant. The approach predicts that unique blue and unique yellow should be aligned in chromatic space while unique red and unique green should not, a fact usually conjectured to result from nonlinearities in chromatic pathways.

The Relationship

It was hypothesized that, in VOC, the relationship between awareness and performance gains would be a function of the experimental conditions during training. Fifty-six naive Ss were assigned to 1 of 4 experimental conditions. Each group performed the Taffel sentence-construction task. This was the only treatment given one group; a second group was required to perform a color-naming task between trials. A third group was required to write their “thoughts about the experiment” between blocks of trials, while a fourth group was required to perform both the intertrial and the inter-block tasks. All groups demonstrated significant performance gains. The color-naming task resulted in significantly less performance gain, as expected, but, contrary to expectation, did not significantly inhibit the development of awareness. The discrepancies between the present results and those of previous studies were explored as were the implications for understanding the VOC process.

The Relationship

The present study was aimed to examine the cognitive functions among adolescents with online game addiction behaviour. For the present study 60 adolescents who play online games were been studied living in Delhi-Ncr region following cross-sectional research design. The instruments used encompassed of a demographic data sheet, Game addiction scale, Stroop color word test, Trail making test, Eysenck’s series of digit span test and n-beck test. The obtained data was been analysed by using SPSS to see the relationship between cognitive functions and game addiction with Pearson-r, frequency distribution and correlation. The findings indicated that gamers who remained preoccupied with playing had difficulty in color naming and indicates withdrawal feature that interfere in their retrieval. And also indicates that online gamers who experienced conflict due to online gaming had significantly deficit in attention and concentration.

The Relationship

The relationship between accuracy of color-naming and color-matching in both visual fields (LVF and RVF) as a function of sex was investigated. Subjects were 19 men and 15 women who ranged in age from 18 to 32 yr. Each subject was tested on both a color-naming task and a color-matching task presented tachistoscopically. Accuracy measures for each task were obtained separately for both left and right visual fields. A two-factor analysis of variance with repeated measures on one factor followed by a t test for simple main effects showed significant right visual-field advantage for the color-naming task, a significant sex main effect for the color-matching task (in the left visual field only), and a significant interaction of sex by visual field for the matching task. Men performed in a more strongly lateralized fashion on the color-matching task than did women, supporting the notion of greater lateralization among males.

The Relationship

The geometry that describes the relationship among colors is unsettled despite centuries of study. Here we present a new approach, using multivariate analyses of direct measurements of brain activity obtained with magnetoencephalography to reverse-engineer the geometry of the neural representation of color space. The analyses depend upon determining similarity relationships among the neural responses to different colors and assessing how these relationships change in time. To evaluate the approach, we relate patterns of neural activity to universal patterns in color naming. Control experiments showed that responses to color words could not decode activity elicited by color stimuli. The results suggest that three patterns of color naming can be accounted for by decoding the similarity relationships in the neural representation of color: the association of warm colors such as reds and oranges with “light” and cool colors such as blues and greens with “dark”; the greater precision among all languages in naming warm colors compared to cool colors; and the preeminence of red.

Verbal Operant

A study to determine the relationship between verbal operant conditioning (VOC) and awareness as measured by Dulany's post-conditioning interview. 76 Ss were given instructions for either a Speed Set or Non-speed Set. Taffel's sentence-completion task was used with an intertrial color-naming task. Reinforced Ss showed a significant increase in VOC ( p < .01), while the Nonreinforced Ss showed no increase in VOC ( p > .05). Speed Set vs Non-speed Set had no significant effect upon either VOC or awareness ( p > .05). The results supported the position of Spielberger and DeNike, in which awareness is considered to be a necessary mediating factor for VOC.
