In psychology, egocentrism is defined as a) the incomplete differentiation of the self and the world, including other people and b) the tendency to perceive, understand and interpret the world in terms of the self. The term derives from the Greek egô, meaning “I”. An egocentric person has no theory of mind, cannot “put himself in other people’s shoes,” and believes everyone sees what s/he sees (or that what s/he sees, in some way, exceeds what others see.)

It appears that this is shown mostly in younger children. They are unable to separate their own beliefs, thoughts and ideas from others. For example, if a child sees that there is candy in a box, he assumes that someone else walking into the room also knows that there is candy in that box. He reasons that “since I know it, you should too”.
