In this paper, I describe the field of developmental psychopathology, discuss its major tenets, and delineate its boundaries with other disciplines with an eye toward the future. I articulate how I envision those aspects of developmental psychopathology that I view as central to the discipline affecting the field and evolving over time. The current status and suggested directions for a number of issues are discussed, including: the interface between normal and abnormal development; developmental mechanisms and processes across the life span; the need for an interdisciplinary approach; prevention and intervention; and training. I believe that a continued and expanded interface between the study of normal and atypical development will span the dualisms that exist between the clinical study of and research into disorders of childhood and adulthood, between basic and applied research, and between psychology and biology. If fostered, I envision an exciting new era of theoretical and empirical work in the developmental sciences.
