Color vision and brightness discrimination in two-month-old human infants.

A red or white bar, embedded in a white screen, was systematically varied in intensity. Infants consistently located and stared at the white bar unless it closely matched the screen in intensity. They also stared at all intensities of the red bar, presumptively including the red-white brightness match, and hence must have some form of color vision.
