Some of the major changes that have influenced the field of child development since the last edition (1964) are presented in this edition. The book is divided into six parts, each with an introduction that summarizes what is important in the various domains of child development. Part One, The Grand Systems, is intended to give the reader a solid theoretical foundation with which to approach the individual papers. The "grand systems," or major schools are identified as the psychoanalytic, the behaviorist, and the interactionist, and papers by authors closely identified with each system are included. The papers in the other five parts of the book reflect one of the theoretical approaches introduced in Part One. These five parts are: Part Two, The Culture and the Child: Cross-Cultural, Class, and Ethnic Differences; Part Three, Infancy; Part Four, Perceptual and Cognitive Development; Part Five, Socialization Processes; and Part Six, Socializing Agents: The Home, The School, and the Peer Group. Author and subject indexes are provided. (Author/DB)
