The huge and fractured literature on adolescence challenges both students and scholars. For students there is too much to learn and too little coherence across topics to enable deeper understanding. For scholars, there are few integrative visions to connect minitheories, research programs, and practical concerns.

In the first edition of this advanced text, Moshman provided a constructivist synthesis of the literatures of cognitive, moral, and identity development, from the classic universalist theories of Piaget, Kohlberg, and Erikson through the more pluralist research and theorizing of the late 20th century. Without assuming any prior knowledge of psychology, he introduced and coordinated basic concepts to enable students to wrestle with the questions of concern to experts and help experts see those concerns from a larger perspective.

In this thoroughly updated second edition, Moshman develops his conceptualization of advanced psychological development in adolescence and early adulthood and proposes–in a new chapter–a conception of rational moral identity as a developmental ideal. Unlike the prototypical changes of early childhood, advanced psychological development cannot be understood as progress through universal stages to a universally achieved state of maturity. Progress is possible, however, through rational processes of reflection, coordination, and social interaction.
