Sensory Development

Visual System



The visual system begins to develop around the ninth and tenth week of gestation and continues developing until three years after birth. At birth, infants are able to detect motion, can focus on an object about eight inches away, are sensitive to brightness, and have red and green color vision. By the end of the second month, infants are able to track smooth pattern movements and begin to discriminate between colors. During the third month, infants are better able to focus on objects farther away and are beginning to develop depth perception, both of which continue to develop until age two or three. Many toy companies gear toys that have geometric shapes and are black and white for newborns, and toys that are brightly colored and have patterns for infants about three months and older. These toys encourage development as the infant's neuronal pathways are being established.
