children show their acquisition of theory of mind (ToM) as early as 4 years old. In this task, children see a scenario where one character hides a marble in a basket, walks out of the scene, and another character that is present takes out the marble and put it in a box. Knowing that the first character did not see the switching task, children were asked to predict where the first character would look to find the marble. The results show that children younger than 4 answer that the character would look inside the box, because they have the superior knowledge of where the marble actually is. It shows egocentric thinking in early childhood because they thought that even if the character itself did not see the entire scenario, it has the same amount of knowledge as oneself and therefore should look inside the box to find the marble. As children start to acquire ToM, their ability to recognize and process others' beliefs and values overrides the natural tendency to be egocentric. During adolescence Although most of the research completed on the study of egocentrism is primarily focused on early childhood development, it has been found to also occur during adolescence. David Elkind was one of the first to discover the presence of egocentrism in adolescence and late adolescence. He argues, "the young adolescent, because of the physiological metamorphosis he is undergoing, is primarily concerned with himself. Accordingly, since he fails to differentiate between what others are thinking about and his own mental preoccupations, he assumes that other people are obsessed with his behavior and appearance as he is himself." This shows that the adolescent is exhibiting egocentrism, by struggling to distinguish whether or not, in actuality, others are as fond of them as they might think because their own thoughts are so prevalent. Adolescents consider themselves as "unique, special, and much more socially significant than they actually are." Elkind also created terms to help describe the egocentric behaviors exhibited by the adolescent population such as what he calls an imaginary audience, the personal fable, and the invincibility fable. Usually when an egocentric adolescent is experiencing an imaginary audience, it entails the belief that there is an audience captivated and constantly present to an extent of being overly interested about the egocentric individual. Personal fable refers to the idea that many teenagers believe their thoughts, feelings, and experiences are unique
