Foundations of Developmental Psychology is designed for the student seeking a comprehensive introduction to developmental psychology as a developmental science. The intent is to introduce the field in a manner comparable to the introductory courses that college students take in biology, chemistry, or physics. The emphasis is on the empirical and theoretical foundations of fundamental human development. The book attempts to trace the origins and processes of various developmental events. Developmental phenomena are presented by topics rather than by chronological, age-related patterns of development. This arrangement of the subject matter provides for more efficient study, integration, and synthesis of the material, along with a more organized view of development. Key topics discussed include the genetic foundations of development; prenatal factors in development; the biological notion of maturation and its significance for development; motor and perceptual development; and cognitive, intellectual, language, emotional, personality, and social development. Although this text is written for undergraduate students in psychology, it can be understood by students in any discipline who have a grasp of introductory psychology and biology.
