Emotional Expression in Infants The following video shows examples from a system that Carroll Izard and his colleagues devised for identifying emotional expression in infants. Each of the emotions shown here--interest/excitement, enjoyment/joy, sadness/dejection, and anger/rage--is illustrated with a photo, an artist’s drawing, and then a video of an infant displaying the emotion.
