from Part II - Perceptual Development
Published online by Cambridge University Press: 26 September 2020
Newborns can see – but only if they are awake with an object right in front of them that is large with elements of high contrast against the background, like the mother’s face. Improvements come rapidly after birth with the maturation of the retina and the visual cortex to which it connects, allowing better input to higher visual areas that underlie the perception of whole objects and their movement. Nevertheless, missing visual input near birth because of dense cataracts in one or both eyes alters the developmental trajectory, even when treatment occurs within the first few months of life. Thus, the early visual input, despite its limitations, is critical for setting up the neural architecture for later refinement.
