David Elkind was a developmental psychologist born in 1931 who received his Ph.D. from UCLA. He was influenced by Piaget and known for his theories on adolescent egocentrism, including the imaginary audience and personal fable. While some critics argued these were not forms of egocentrism, his theories were influential in understanding adolescent psychology and helped many parents and practitioners. He has published over 400 times and currently works at the University of Massachusetts.
