Why do people age differently? Research in the field of gerontology has indicated that there are large individual differences in personality, cognitive functioning, physical health, and psychological well-being, as well as in the quality of life in the later years. It is this variability and the reasons why people age differently that this book explores. Thoughtfully written, Aging presents an overview of what is known about genetic and environmental influences on aging. Beginning with an overview of family, adoption, and twin designs, author Cindy S. Bergeman examines such topics as the research in the area of longevity and health, cognitive functioning, personality, and psychopathology; and social support, life events, and measures of the family environment. The book concludes with a summary of the field of gerontological behavioral genetics. This book will stimulate discussion and future work about the origins of individual differences in later life and will be invaluable to professionals and practitioners in the fields of developmental psychology, psychology, aging, family studies, and nursing.

Biological Aging: A Quantitative Genetic Perspective

As the variability among individuals becomes more apparent in later life, it is evident that the index of chronological age needs to be replaced by other indicators that are more sensitive to individual differences (Schroots & Birren, 1990). One such measure, biological age, is defined as an estimate of the individual's present position with respect to his or her potential life span (Birren, 1959). It has been suggested that patterns of physiological characteristics representing biological age can be used not only to predict the consequences for health and well-being, but for assessing individual differences in the aging process as well (Baker & Sprott, 1988; Schroots & Birren, 1990). This biological index is typically thought ...
