Medical Definition of EGOCENTRIC. 1. : limited in outlook or concern to one's own activities or needs.
According to the developmental psychologist Jean Piaget, children between the ages of three and five go through a stage called egocentrism. The term egocentrism refers to a child's inability to understand another person's point of view; in other words, he or she believes that other children feel, think, and experience life as they do. In many cases, children also take part in egocentric speech.
