To analyze the perceptual abilities of a person, some studies of abilities in infants can be noted. At the age of one month, babies cannot distinguish small details; their vision can only be distinguished by relatively large objects. Visual acuity is weak, facial expressions are difficult to distinguish, they see mostly the external contours of the face. Infants find some forms more interesting than others; they are more inclined to look at forms similar to human faces. By three months, the sharpness improves; the baby can already decipher facial expressions, and he has much more social reactions. He recognizes something in the face of the mother; when viewing he prefers to look at the photo of the mother, and not at the photo of an unfamiliar woman.

The perception of depth begins to appear at about three months of age, but is finally formed only by six months. At the age of four months, the infant begins to reach for the nearest of the two objects, determining which one is located closer to it, thanks to the binocular disparity. Constancy of perception also begins to develop from the first months of life.
