Infant vision concerns the development of visual ability in human infants from birth through the first years of life. The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition .
Visual schedules use a series of pictures to communicate a series of activities or the steps of a specific activity. [1] [2] They are often used to help children understand and manage the daily events in their lives. [3] They can be created using pictures, photographs, or written words, depending upon the ability of the child.

Early childhood intervention came about as a natural progression from special education for children with disabilities (Guralnick, 1997). Many early childhood intervention support services began as research units in universities (for example, Syracuse University in the United States and Macquarie University in Australia) while others were developed out of organizations helping older children.
During early development, infants begin to crawl, sit, and walk. These actions impact how the infants view depth perception. Thus, infant studies are an important part of the visual cliff. When an infant starts to engage in crawling, to sit, or walking, they use perception and action. During this time, infants begin to develop a fear of height.
