Object Permanence is the an understanding that things can exist when they are out of sight and sound.
These interactions with people, objects are literally the child’s tools of the trade for developing language.
The more tools children have for learning in these first two years, the better students of concept and language development they will be.
3. Object Permanence: A symbol is not a call to action. It is a call to bring information about something into the mind.
More often, that something is not present at the time, or may not even exist (like Santa Clause).
This all rests on the basic concept of “Object Permanence”--the understanding that something can exist even if it is not in our presence.
Piaget’s classic example is an infant who wants an object, like a bottle.
