How The Brain Processes The External World Using Overlapping Visual Circuits

A new study from Salk Institute researchers demonstrates that there are neurons that respond selectively to particular combinations of color and shape. “New genetic sensors and imaging technologies have allowed us to more thoroughly test the link between visual circuits that process color and shape. These findings provide valuable insight about how visual circuits are […]

How A Blind Artist Is Challenging Our Understanding Of Color

For centuries, people who were born blind have been the intellectual curios of philosophers studying consciousness. This is particularly true for those exploring the way our consciousness is effected by our bodies, especially our eyes, which Leonardo da Vinci described as the “window of the soul”. One interesting fallacy is the belief that people born […]

Social Color Signals May Have Influenced Trichromatic Color Vision

The arrangement of the photoreceptors in our eyes allows us to detect socially significant color variation better than other types of color vision, researchers have found. Our color vision is superior at spotting “social signaling,” such as blushing or other facial color changes, even compared to the type of color vision that we design for […]

Effects Of Artificial Lighting’s Color On Cognitive Performance

The intensity of artificial lighting has been shown to have a range of effects on our mood and our ability to concentrate. New research explores the color of lighting and its effect on our cognitive performance. The study was conducted by Kyungah Choi and Hyeon-Jeong Suk, associate professor of industrial design at the Korea Advanced […]

Prelinguistic Infants Are Able To Categorize Colors

Researchers have revealed that infants aged between 5 and 7 months hold the representation of color categories in their brain, even before the acquisition of language. A long-held theory called Sapir-Wharf hypothesis claims that languages define our perceptions. This theory is widely accepted in various fields of study including psychology, linguistics and anthropology. Color perception […]
