longer period of time shall not be taken by an infant  to visualize something  which he/she is habituated
Explanation:
Researchers like  Renee Baillargeon estimate the infants’ visual response to object occlusions as a base of giving any theory about permanence
Once a child gets habitualize by watching some thing, his her visual response time as well as the staring attribute of vision reduces. Â
