In this bestselling textbook, contributors describe theories of normal human development advanced by such pioneers as Sigmund Freud, Anna Freud, Jean Piaget, Nancy Chodorow, Daniel Levinson, Erik Erikson, and Margaret Mahler. Beginning with infancy, toddlerhood, and preschool, each chapter examines corresponding ideologies concerning maturation and development in middle childhood, adolescence, adulthood, and old age, while acknowledging that no one theory can encompass all aspects of human development. In-depth analyses of the psychology and sociology of development provide educators and practitioners with insights into the specific social contexts of human behavior and help identify variables and deviations. This second edition features up-to-date empirical information, including additional studies on diverse populations, and a new chapter on attachment theory, a growing area of interest for today's clinicians.
