Egocentrism

Explanation: Piaget theory of cognitive development aim to the growth and development the the intelligence of man and his nature. Egocentrism according to Piaget is known to be the inability of a child's to see or recognize the viewpoint of others about a particular situation, information or view. An egocentric child in his theory is one who literally knows or assumes other point of view, what they see, hear, and feel from their own eyes or viewpoint. Children in this stage does not really know more on viewpoints. They believe what they like is what the other person must like. E.g a child likes snow-white drama, the child will equally say that his dad loves snow-white drama too. In this case the children has already decided for the father without hearing from the father if he likes the drama or not.
