Developmental Influences on Adult Intelligence: The Seattle longitudinal study Updated Edition

"There are probably no books that can compare with this one in the field of adult intelligence. The Seattle Longitudinal Study has been going on for 49 years under the direction of the principle researcher, Dr. Schaie. Everything you wanted to know about intellectual development and changes in adulthood is here. It is fascinating reading and is ful of statistical analysis. This book is comprehensive and readers will not be disappointed." --Doody's

"This work represents an extraordinary odyssey in the field of human cognition. Dr. Schaie's lifetime effort in the longitudinal study is unparalleled. This publication gives the history of a project that has lasted decades, its ups and downs, and its surprising conclusions about what happens to human intellect over the life span. I recommend this work to all those interested it what happens to their intellect over time, as well as to students, physicians, and psychologists treating patients and performing gerontologic research." --Jerome Yesavage, Professor of Psychiatry and Behavioral Sciences, Stanford University

"Developmental Influences on Adult Intelligence is the most recent summary of findings from the Seattle Longitudinal Study. This remarkable study, initiated in 1956, is arguably the longest running and most comprehensive examination of intellectual aging available today. The present volume is a follow-up to Professor Schaie's 1996 monograph Intellectual Development in Adulthood. In addition to reviewing the design and method of the SLS and updating cross-sectional and longitudinal findings to include results from the 1998 longitudinal cycle, the present volume breaks new ground with an extensive examination of how environmental, health-related, and familial influences affect intellectual development across adulthood. This wealth of new information will be of interest to all gerontologists." --David Hultsch, Director, Centre on Aging, University of Victoria

"Developmental Influences on Adult Intelligence is a tour de force. The Seattle Longitudinal Study, unparalleled in its comprehensive account of intellectual change across adulthood, played a critical role in the scientific understanding of intelligence. In this volume, K. W. Schaie, who started the study and centrally led the field, synthesizes decades of research into a highly readable story about the gains and losses associated with intellectual performance as people age, the roles played by personality, family, and health in age-related changes, and the challenges of conducting longitudinal research. This volume is essential reading for anyone who desires a nuanced account of intellectual aging." --Laura L. Carstensen, Professor of Psychology, Stanford University

"Understanding the intelligence of the mind across the stages of life and across historical contexts is central to the science of human aging. Schaie's longitudinal study, spanning close to 50 years and several generations, defines the field and, in addition, illustrates how a creative longitudinal scholar is able to rejuvenate his work by extensions in theory and method. This book will be a classic!" --Dr. Paul B. Baltes, Sekretariat Professor, Max Planck Institute for Human Development
