The role of both genetic and environmental influences has a large part in the physical, psychosocial and cognition development of infants. Even an infant’s temperament can easily be determined by those same influences. Their temperament can also affect the manner in which they proceed through Piaget’s six sensorimotor substages. Since the moment a baby is conceived, both the genes from the mother and father, plus the environmental factors will play a role on an infant’s physical development.
