The Handbook of Research Methods in Developmental Science brings together a team of leading developmental scientists to provide a state-of-the-art overview of methods and approaches associated with the study of human development. It contains accessible contributions from some of the most renowned developmental scientists in the field. Topics discussed include: traditional and complex designs in developmental research and the strengths and challenges inherent in each; the use of experimentation and quasi-experimentation in studies of development; developmental measurement issues; conceptualizations of change and approaches to assess it; intervention approaches to promote development in high-risk samples; and cutting-edge research that is forging new and exciting directions in developmental research. This volume is a vital resource for students and scholars wishing to gain a working understanding of research approaches and issues in the developmental sciences.
