<p>The concept of identity is one of the most important ideas the social sciences have investigated in recent years, yet no introductory textbooks are available to those who want to gain a sense of this burgeoning field. The first of its kind, this text provides an introduction to the scientific study of identity formation, with a focus on youth development. The analyses of the problems and prospects faced by contemporary young people in forming identities are placed in the context of societies that themselves are in transition, further complicating identity formation and the interrelated processes of self development and moral-ethical reasoning.</p><p>In order to sort through what is now a vast literature on the various aspects of human identity, this book introduces the Simplified Identity Formation Theory. This theory cuts through much of the academic jargon that limits the accessibility of this promising field, and builds an understanding of human identity from first principles. Part I outlines the philosophical and theoretical roots of the &quot;identity question,&quot; explores different historical and cultural contexts, and provides a framework for studying the multifaceted nature of contemporary identity formation. Part II examines related forms of human development, focusing on perspective-taking and moral reasoning, and how these are related to ethics and forms of agency. Part III completes the book by examining the scientific evidence concerning identity formation in various societal contexts, along with the interventions that can be undertaken to foster optimal development. A robust website also accompanies this text, containing everything from flashcards to a study guide for students, and an instructor manual to PowerPoint Presentations for instructors.</p>
