Infants can see image differences that adults cannot, study finds

Babies may be able to see image details that are invisible or imperceptible to adults. According to a recent study from Japanese scientists Jiale Yang, So Kanazawa, Masami K. Yamaguchi, and Isamu Motoyoshi, three- and four-month-old infants may view certain images differently because they lack perceptual constancy. That means they can see small image differences that are invisible to adults because of changes in lighting conditions.

For example, when adults see the same objects in different lighting, their brains automatically adjust to those lighting conditions. If your friend steps in front of a blue spotlight, they might appear blue, but you still recognize them. That’s perceptual constancy in action: Your brain recognizes that, though your friend is bathed in blue light, they aren’t suddenly a totally different blue person. Young babies who haven’t yet developed perceptual constancy, meanwhile, are able to see subtle images differences that adults ignore, but may be unable to recognize the same objects in different light.

GaN FETs: D-Mode Vs E-mode
Sponsored by Mouser Electronics and Nexperia
The use of gallium nitride can offer higher power efficiency, increased power density and can reduce the overall size and weight of many industrial, automotive, and data center applications. In this episode of Chalk Talk, Amelia Dalton and Giuliano Cassataro from Nexperia investigate the benefits of Gan FETs, the difference between D-Mode and E-mode GaN FET technology and how you can utilize GaN FETs in your next design.
