Book excerpt: "The Gerontological Prism" promotes disciplinary cooperation in aging research and practice. To some extent, each chapter explores a unified objective, that of generating a disciplinary-blind gerontology. The fundamental assumption throughout this book is that the aging individual and society can be enhanced by an understanding of the correlates of basic social, behavioral, demographic, economic, political, ethical, and biomedical processes involving aging. Each author touches on issues that have both social psychological, and practical policy significance. They aim toward sensitizing the reader to the possibilities of a properly informed interdisciplinary approach to gerontology.
