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.
Developmental norms are sometimes called milestones – they define the recognized development pattern that children are expected to follow. Each child develops in a unique way; however, using norms helps in understanding these general patterns of development while recognizing the wide variation between individuals.
It is an important milestone in the stages of cognitive development for infants. Numerous tests regarding it have been done, usually involving a toy and a crude barrier which is placed in front of the toy, and then removed repeatedly . In early sensorimotor stages, the infant is completely unable to comprehend object permanence.

Middle childhood/preadolescence or ages 6–12 universally mark a distinctive period between major developmental transition points. [ 2 ]
However, images still appear unclear at two months due to other components of the visual system like the fovea and retina and the brain circuitry that are still in their developmental stages. This means that even though an infant is able to focus on a clear image on the retina, the fovea and other visual parts of the brain are too immature to ...
Babies born during the early months of the pandemic scored slightly lower on a screening of their developmental skills than those born prior to the pandemic, regardless of whether their mothers ...
