Perception is the ability of humans to acquire information from the world through their senses. Perceptual development refers to the development of these senses, and this takes place mainly in the first year of life, according to the majority of research into this area. The sensory organs of children and their connections with the respective areas of the central nervous system show a dramatic development during the first year of life. Many of the experiments in this area are concerned with the development of the visual apparatus, e.g. depth perception, binocular information, the perception of faces and the visual preferences of children.
