In the first edition of this text, Moshman (University of Nebraska- Lincoln) provided a constructivist synthesis of the literature of cognitive, moral, and identity development, from classic universalist theories through the more pluralistic research of the late 20th century. In this second edition, he develops his conceptualization of advanced psychological development in adolescence and, in a new chapter, proposes a conception of rational moral identity as a developmental ideal. The book concludes with a chapter on the importance of intellectual freedom in secondary education. No prior knowledge of psychology is assumed.
