Life-Span Development Psychology: Research and Theory covers the issues and problems associated with a life-span conceptualization of developmental psychology. The book discusses the status, issues, and antecedents of life-span developmental psychology; an approach to theory construction in the psychology of development and aging; and models and theories of development. The text also describes the methodology and research strategy in the study of developmental change; the application of multivariate strategies to problems of measuring and structuring long-term change; and the mechanisms required for the operation of perception and recognition. Learning and retention; language; and intellectual abilities are also considered. Developmental psychologists will find the study invaluable.
