ABSTRACT
This paper describes the different forms of egocentrism characteristic of each of the major stages of cognitive growth outlined by Piaget. Particular attention is paid to the egocentrism of adolescence which is here described as the failure to differentiate between the cognitive concerns of others and those of the self. This adolescent egocentrism is said to give rise to 2 mental constructions, the imaginary audience and the personal fable, which help to account for certain forms of adolescent behavior and experience. These considerations suggest, it is concluded, that the cognitive structures peculiar to a given age period can provide insights with respect to the personality characteristics of that age level.
