The nature of developmental psychology

This chapter sets the scene for those that follow, considering the nature of developmental psychology/developmental science and outlining some either-or controversies that have characterized theorizing in the field. The basic question of ‘what is development’ is addressed, including the concept of developmental ‘mechanisms’. Attention is paid to the course of development in relation to a lifespan perspective, developmental cascades and trajectories. Reasons for studying development are considered, and the nature of theories and metatheories is discussed. While a post-positivist outlook is still the major epistemological influence on the field of developmental psychology, a more critical approach has also been taken, especially by Erica Burman, including a push to decolonize the field along with taking a social justice perspective.
