Known for its clear, straightforward writing, grounding in current research, and well-chosen visuals and examples, Sigelman and Rider's text combines a topical organization at the chapter level and a consistent chronological presentation within each chapter. Each chapter focuses on a domain of development and traces developmental trends and influences in that domain from infancy to old age. Each chapter also includes sections on infancy, childhood, adolescence, and adulthood. The blend of topical and chronological approaches helps students grasp key transformations that occur in each period of the life span. Other staples of the text are its emphasis on theories and their application to different aspects of development and its focus on the interplay of nature and nurture in development. This edition expands its examination of both biological bases of and sociocultural influences on life-span development, and offers an exciting new media package for both students and instructors.
