Formal operations, the imaginary audience and the personal fable.

One hundred twenty-nine 6th, 8th, 10th/11th, and 12th graders were administered Enright, Lapsley, and Shukla's Adolescent Egocentrism Scale (AES) and How Is Your Logic?, a Piagetian-based, group-administered, written test of cognitive development. A series of ANOVAs on four scales of the AES (imaginary audience, personal fable, self-in-general, nonsocial) provided partial support for Inhelder and Piaget's, and Elkind's views that adolescent egocentrism is a function of beginning formal operations. Discussion focused on the difficulty of assessing the true thoughts/feelings of persons who are worried how they will appear to others.
