Visual loss in children or infants can occur either at the prenatal stage (during the time of conception or intrauterine period) or postnatal stage (immediately after birth). [3] There are multiple possible causes of congenital blindness.
Eye development is initiated by the master control gene PAX6, a homeobox gene with known homologues in humans (aniridia), mice (small eye), and Drosophila (eyeless). The PAX6 gene locus is a transcription factor for the various genes and growth factors involved in eye formation. [1] [5] Eye morphogenesis begins with the evagination, or ...
t. e. Child development stages are the theoretical milestones of child development, some of which are asserted in nativist theories. This article discusses the most widely accepted developmental stages in children. There exists a wide variation in terms of what is considered "normal", caused by variations in genetic, cognitive, physical, family ...
Robert Lowell Fantz [1] (1925–1981) [2] was an American developmental psychologist who pioneered several studies into infant perception. In particular, the preferential looking paradigm introduced by Fantz in the 1961 is widely used in cognitive development and categorization studies among small babies. Working at the Case Western Reserve ...
Primitive reflexes. Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development. [ 1]
A human baby, the best-known altricial young. In birds and mammals altricial species are those whose newly hatched or born young are relatively immobile, lack hair or down, are not able to obtain food on their own, and must be cared for by adults; closed eyes are common, though not ubiquitous. Altricial young are born helpless and require care ...

The academic field of infant cognitive development studies of how psychological processes involved in thinking and knowing develop in young children.
