A standardized and objectively scored scale of adolescent egocentrism-sociocentrism (AES) and a self-consciousness scale were given to 44 subjects each in the sixth, eighth, tenth, and twelfth grades and college. The AES assesses three components of egocentrism including the personal fable, the imaginary audience, and general self-focuses, as well as sociocentrism and nonsocial subscales. As predicted, the personal fable and imaginary audience declined with age. The self-focus subscale showed a curvilinear relationship with age, while, again as predicted, sociocentrism increased and nonsocial focuses declined. Adolescent egocentrism, as expected, correlated positively with self-consciousness even with age controlled. Implications for the theories of egocentrism and sociocentrism in the adolescent years are discussed.
