Egocentrism is the inability to differentiate between self and other. More specifically, it is the inability to accurately assume or understand any perspective other than one's own. Egocentrism is found across the life span: in infancy, early childhood, adolescence, and adulthood. Although egocentric behaviors are less prominent in adulthood, the existence of some forms of egocentrism in adulthood indicates that overcoming egocentrism may be a lifelong development that never achieves completion. Adults appear to be less egocentric than children because they are faster to correct from an initially egocentric perspective than children, not because they are less likely to initially adopt an egocentric perspective.

Initially when children begin to have social interactions with others, mainly the caregivers, they misinterpret that they are one entity, because they are together for a long duration of time and the caregivers often provide for the children's needs. For example, a child may misattribute the act of their mother reaching to retrieve an object that they point to as a sign that they are the same entity, when in fact they are actually separate individuals. As early as 15 months old, children show a mix of egocentrism and theory of mind when an agent acts inconsistently with how the children expect him to behave. In this study the children observed the experimenter place a toy inside one of two boxes, but did not see when the experimenter removed the toy from the original box and placed it in the other box, due to obstruction by a screen. When the screen was removed the children watched the experimenter reach to take the toy out of one of the boxes, yet because the children did not see the switching
