According to piaget, egocentrism is to conservation as the stage is to the stage.

Preoperational stage is to the concrete operational stage.

Explanation:

Piaget divides the cognitive development into four stages;

During the Preoperational stage, the child is still unable to look at a situation from someone else's point of view, hence, the child is egocentric since he/she assumes that the world views everything exactly like he/she does.

Conservation develops during the Concrete operational stage, when the child is starting to grasp logic and operational thoughts. In this stage, the child is able to "conserve" numbers in his/her mind to carry out concrete operations.

To summarize, egocentrism appears in the Preoperational stage and conservation in the Concrete operational stage.
