The present study was conducted on a total of 1,002 individuals belonging to 9 caste,11 backward caste and 5 scheduled caste endogamous groups, as well as a few from Muslim and Christian r...

Many species of stomatopod crustaceans have multiple spectral classes of photoreceptors in their retinas. Behavioral evidence also indicates that stomatopods are capable of discriminating objects by their spectral differences alone. Most animals use only two to four different types of photoreceptors in their color vision systems, typically with broad sensitivity functions, but the stomatopods a...

This paper compares color imaging principles and techniques of color quantification symbolizing the scheme of reality, human vision, and computer vision in analogy to the additive primaries red, green, and blue, respectively. The certain but unknown reality is not covered completely neither by human nor by computer vision. Up to now, most image processing techniques are designed to fit computer...

The present study examined the effects of role-play experience on children's mindreading ability. Forty-one primary school children (20 boys, 21 girls, mean age: 9.37 years, range: 8-11 years) were introduced to a communication task in which the use of mindreading was essential. During each trial, participants viewed a shelf, presented on a laptop, which contained several familiar objects, and ...

Acquired disturbances of color vision are a highly varied group of defects with frequent departures from established patterns. They can progress from normal trichromatism to anomalous trichromatism on to a dichromatic stage and to monochromatism where most color vision is lost, or they may be relatively stable [1]. A significant “modern effort” to present such conditions was published for first...

The present study examined effects of role-play experience on reading the mind of people with different perception. It is normally difficult but very important in daily life to understand people with different characteristics, including those with restricted color vision. We explored the mechanisms of reading the mind of people with different perception. Forty university students were introduce...

This contribution expounds on ideas put forth by a group of New York City generative grammarians that language possesses certain essential features that are uncaused and adhere to an abstract ideal form. An analogy of the situation with language is made with certain natural properties of numbers. It is also noted that this situation contrasts with that of the functional structure of human color...
