Behavior Genetics Of Cognition Across The Lifespan

Along with psychopathology, cognition has been one of the primary phenotypic focal points of the field of behavior genetics since its inception. Francis Galton’s 1874 examination of eminent families in Britain was among the earliest attempts to investigate whether cognitive achievements run in families. This volume presents current methodologies for understanding cognitive abilities that move beyond the outdated nature vs. nurture paradigm. Recent advances in both collection and statistical modeling of twin data, particularly longitudinal twin data, make this an especially advantageous moment to produce a work that presents a collection of the groundbreaking research on cognitive abilities across the lifespan. This volume presents an overview of the current state of quantitative and molecular genetic investigations into the many facets of cognitive performance and functioning across the lifespan.​

Based on the First Biannual Lifespan Development Conference, this volume offers a multidisciplinary and multidimensional approach to the study of lifespan development in the areas of neuropsychology, cognition, behavior genetics, and perception. The objective of the conference was to provide a lively forum for the discussion of issues related to lifespan development and to reflect on important topics challenging the field during the 1990s. The chapters in this book, motivated by the conference presentations, cover: * the assessment and evaluation of developmental changes in visual perception; * the contribution of behavioral genetic factors to development; * the predictability of perinatal risk factors as they relate to cognitive and linguistic outcomes; * the neuropsychological changes during aging; and * innovative approaches to the study of cognitive development using neuropsychological testing methods.

This volume examines behavioral genetic research on temperament and personality from a number of perspectives. It takes a developmental perspective on a number of issues across the lifespan, focusing on personality and temperament. The first section focuses on the development of temperament and personality. Typically this has involved exploring genetic and environmental contributions to phenotypic stability and instability, but more recently there has been research that examines the etiology of intra-individual change/growth trajectories. The second section examines genetic and environmental contributions to the association between temperament and personality and other behaviors. The third and fourth sections discuss genotype-environment correlations and interactions, and introduces the reader to molecular genetics research on temperament and personality. Chapter 11 will discuss the significance of this type of research and Chapter 12 will provide an example of specific line of research exploring genes associated with temperament.​

K. Warner Schaie I am pleased to write a foreword for this interesting volume, particularly as over many years, I have had the privilege of interacting with the editors and a majority of the con tributors in various professional roles as a colleague, mentor, or research collaborator. The editors begin their introduction by asking why one would want to read yet another book on human development. They immediately answer their question by pointing out that many developmentally oriented texts and other treatises neglect the theoretical foundations of human development and fail to embed psychological constructs within the multidisciplinary context so essential to understanding development. This volume provides a positive remedy to past deficiencies in volumes on hu man development with a well-organized structure that leads the reader from a general introduction through the basic processes to methodological issues and the relation of developmental constructs to social context and biological infrastructure. This approach does not surprise. After all, the editors and most of the contributors at one time or an other had a connection to the Max Planck Institute of Human Development in Berlin, whether as students, junior scientists, or senior visitors. That institute, under the leader ship of Paul Baltes, has been instrumental in pursuing a systematic lifespan approach to the study of cognition and personality. Over the past two decades, it has influenced the careers of a generation of scientists who have advocated long-term studies of human development in an interdisciplinary context.

"The handbook is an impressive collection of research studies and theories provided by knowledgeable contributors on life-span development from conception to old age."--Anthropology and Aging Quarterly The doubling of our average life span since the turn of the 20th century is considered by many scholars to be one of the most important changes in human existence. This definitive text is the only volume to fully address, through a multidisciplinary perspective, the biological, cognitive, and psychological development that occurs from infancy through old age, and how the sociocultural and institutional factors interface with these changes. Edited by leading research scholars in the field of life-span development, the volume also includes contributions of specialists in behavioral genetics, socioemotional selectivity theory, neuroscience, ecological models, and more. It examines the dynamics of close relationships and informal ties among the elderly population, child-parent attachment relationships as a life-span phenomenon, developmental tasks across the lifespan, continuity and discontinuity in temperament and personality, the sociocultural context of cognition across the life span, and variability in approaches to social problem solving from early to later life. Given the number of recent demographic shifts, it also explores issues related to fertility, life expectancy, environmental contexts, technology, immigration, and public policy. Key Features: Integrates the full life span from infancy through old age in each chapter Considers multidisciplinary perspectives that address personal relationships, cognitive development, and social, emotional, and physical health across the life span Situates life-span development in ecological contexts (e.g., socioeconomic, neighborhood, and immigration status) Provides a concise but thorough resource for graduate seminars in life-span-related studies Highlights future issues in all areas of life-span study

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.

While targeted to undergraduate and graduate students, this compendium will prove a valuable resource for scholars already familiar with twin studies, as well as those coming to the field for the first time. Here, more than forty experts across an array of disciplines examine twinning and twin research methodologies from the perspectives of biology, medicine, genetic and epigenetic influences, and neuroscience. Chapters provide clear instruction in both basic and advanced research methods, family and parenting aspects of twinning, twin studies as applied across various disease areas and medical specialties, genetic and epigenetic determinants of differentiation, and academic, neurological and cognitive development.
