Behavioral development is a major subject area in both animal behavior and experimental psychology since throughout the history of psychology and ethology, the study of development has played a crucial role and has been the subject of some of the major intellectual debates, for example the "Nature versus Nurture" issue. More recently, biological approaches to development, derived from work on animals, have become increasingly important and influential. The Development of Animal Behaviour: A Reader provides the key readings in these important areas of research in one volume. This Reader will therefore prove an invaluable resource for students and scholars who wish to engage with the study of animal behavioral development.
