Colour perception, an essential aspect of human vision, enables us to interpret and interact with our environment reliably despite fluctuating illumination. At the core of this capability is colour ...

PERCEPTUAL constancy refers to relative stability in judgments of an object property with changes in its sensory stimulus. For example, visual judgments of the size and shape of objects are relatively ...

For an enlightening perspective on how primates acquire color vision, consider baby monkeys. These infants’ ability to recognize basic colors in different environmental settings depends on their prior ...

Even when we consciously know two lines are the same length, why can't we help seeing them as different? ILLUSIONS are anomalies that can reveal clues about the mysterious workings of the brain to ...

Why is an object’s size perceived the same regardless of changes in distance? A group of researchers at Osaka University found that neurons in the monkey visual cortical area V4*1, one of the areas in ...

Babies may be able to see image details that are invisible or imperceptible to adults. According to a recent study [PDF] from Japanese scientists Jiale Yang, So Kanazawa, Masami K. Yamaguchi, and ...

Rearing experimental animals under special illumination, researchers have found new evidence that early visual experience is indispensable for the development of normal color perception. The ...
