Reversibility

Explanation:

Reversibility is the capability of reversed things. It is the ability to re-establish the original condition after the change by reverse. It can be said that we can wear a dress on both sides. In Paget's cognitive development the third stage called the concrete operational stage ( pre-operational stage) in which a child develops only logical thinking also develops concept reversibility. It means that several things can be changed and returned to its original state.

For example when a child sees that his ball is default but he does know that the ball can be in its original form by filling the air in the ball.
