In the 1960's and 1970's, personality and mental illness were conceptualized in an intertwined psychodynamic model. Biological psychiatry for many un-weaved that model and took mental illness for psychiatry and left personality to psychology. This book brings personality back into biological psychiatry, not merely in the form of personality disorder but as part of a new intertwined molecular genetic model of personality and mental disorder. This is the beginning of a new conceptual paradigm!! This breakthrough volume marks the beginning of a new era, an era made possible by the electrifying pace of discovery and innovation in the field of molecular genetics. In fact, several types of genome maps have already been completed, and today's experts confidently predict that we will have a smooth version of the sequencing of the human genome -- which contains some 3 billion base pairs Such astounding progress helped fuel the development of this remarkable volume, the first ever to discuss the brand-new -- and often controversial -- field of molecular genetics and the human personality. Questioning, critical, and strong on methodological principles, this volume reflects the point of view of its 35 distinguished contributors -- all pioneers in this burgeoning field and themselves world-class theoreticians, empiricists, clinicians, developmentalists, and statisticians. For students of psychopathology and others bold enough to hold in abeyance their understandable misgivings about the conjunction of "molecular genetics" and "human personality," this work offers an authoritative and up-to-date introduction to the molecular genetics of human personality. The book, with its wealth of facts, conjectures, hopes, and misgivings, begins with a preface by world-renowned researcher and author Irving Gottesman. The authors masterfully guide us through Chapter 1, principles and methods; Chapter 4, animal models for personality; and Chapter 11, human intelligence as a model for personality, laying the groundwork for our appreciation of the remaining empirical findings of human personality qua personality. Many chapters (6, 7, 9, 11, and 13) emphasize the neurodevelopmental and ontogenetic aspects of personality, with a major emphasis on the receptors and transporters for the neurotransmitters dopamine and serotonin. Though these neurotransmitters are a rational starting point now, the future undoubtedly will bring many other candidate genes that today cannot even be imagined, given our ignorance of the genes involved in the prenatal development of the central nervous system. Chapter 3 provides an integrative overview of the broad autism phenotype, and as such will be of special interest to child psychiatrists. Chapters 5, 8, and 10 offer enlightening information on drug and alcohol abuse. Chapter 14 discusses variations in sexuality. Adding balance and mature perspectives on how all the chapters complement and sometimes challenge one another are Chapter 2, written by a major figure in the renaissance of the relevance to psychopathology of both genetics and personality; Chapters 15-17, informed critical appraisals citing concerns and cautions about premature applications of this information in the policy arena; and Chapter 18, a judicious contemplation by the editors themselves of this promising -- and, to some, alarming -- field. Clear and meticulously researched, this eminently satisfying work is written to introduce the subject to postgraduate students just beginning to develop their research skills, to interested psychiatric practitioners, and to informed laypersons with some scientific background.

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.​

At a time when the complete human genome has been sequenced and when seemingly every week feature news stories describe genes that may be responsible for personality, intelligence, even happiness, Michel Morange gives us a book that demystifies the power of modern genetics. The Misunderstood Gene takes us on an easily comprehensible tour of the most recent findings in molecular biology to show us how--and if--genes contribute to biological processes and complex human behaviors. As Morange explains, if molecular biologists had to designate one category of molecules as essential to life, it would be proteins and their multiple functions, not DNA and genes. Genes are the centerpiece of modern biology because they can be modified. But they are only the memory that life invented so that proteins could be efficiently reproduced. Morange shows us that there is far more richness and meaning in the structure and interactions of proteins than in all the theoretical speculations on the role of genes. The Misunderstood Gene makes it clear that we do not have to choose between rigid genetic determinism and fearful rejection of any specific role for genes in development or behavior. Both are true, but at different levels of organization. Morange agrees with those who say "we are not in our genes." But he also wants us to understand that we are not without our genes, either. We are going to have to make do with them, and this book will show us how.

This text provides a summary of what is currently known about the diagnosis, assessment, construct validity, etiology, pathology, and treatment of personality disorders. It also provides extensive coverage of the many controversial changes for the DSM-5, including chapters by proponents and opponents to these changes.

'In the past decade there has been an explosion of research into the psychology of well-being. While we know that psychological well-being is partly heritable, it is only recently that researchers have started to investigate the specific genetic factors that influence well-being. Such research explores not only heritability, based on traditional twin study designs, but also includes studies combining some of the most recent molecular genetic techniques and methods. This landmark book summarizes the state of knowledge regarding heritability and molecular genetics in positive psychology. Divided into four parts, it starts by exploring the basics of genetics and associated research methodology, providing the reader with the knowledge required to understand the empirical work presented throughout the volume. The second part of the book focuses on heritability estimates of the most important positive psychology concepts based on quantitative behavioural genetics studies. In the third section of the book, results from more recent molecular genetics studies are presented including candidate gene, gene-environment interaction, as well as genome-wide association studies. This section also contains chapters on epigenetics and imaging genetics, both relatively new methodologies that are just about to make their way into the field of positive psychology. The fourth and final part of the book discusses more overarching questions regarding the roles of genes and environment in the development of well-being as well as a review and discussion of the current state of knowledge and future direction in this new field of inquiry. The first book of its kind, The Genetics of Psychological well-being is a major contribution to the positive psychology literature, and important for all those in the fields of positive psychology, psychiatric genetics, and well-being.

Twins as a Tool of Behavioral Genetics Edited by T. J. Bouchard, Jr. P. Propping Every human being is genetically unique and consequently genetically different from every other human being. The one exception is identical (monozygotic) twins, who share exactly the same genome. Fraternal (dizygotic) twins share half of their genes in common by descent. Twins of both types constitute "an experiment of nature". Because it is unethical to carry out powerful experiments on human beings in order to explore the causes of variation in human traits, this natural experiment with all of its vicissitudes is one of the few windows we have with which to view the genetic and environmental determinants of complex human behavioral traits. Many scientists believe that twins can only be used to estimate "heritability" and that they reveal nothing about how genes influence behavior. In addition, they argue that modern molecular genetics will quickly make twin research obsolete. These widely held views are largely incorrect. Twins are a unique and very powerful tool for exploring a wide variety of hypotheses about both the distal (mostly genetic) and proximal (mostly environmental) origins of human individual differences. Scientific knowledge accumulates most rapidly when scientists ask the right questions and utilize the right tools—the right tools for the job. This book attempts to highlight the questions that might be most productively addressed through the use of twin designs. Every tool, however, has its limitations. This book carefully examines the limitations and assumptions associated with the application of the method to each of the domains discussed. Goal of this Dahlem Workshop: to evaluate the environmental and genetic mechanisms underlying the structure and development of behavior in twins studies: the achievements, limitations, and potentials.

A comprehensive view of the most heated debate of our time -- are genes the primary influence on human personality and behavior? In presenting the recent findings, William Wright argues that in a century dominated by psychoanalytic thought, there has been an insistence that humans, unlike all other species, are brought into the world as blank slates on which personalities are etched by the environment. Wright describes the overthrow of this view by psychologists and geneticists whose discoveries, most dramatically through studies of identical twins separated at birth, have resulted in the recognition of the major role played by genes in personality and behavior. Wright describes how molecular biologists have reinforced these findings by locating the links between genes and behavior in DNA itself. And he explores the exciting future prospects of treating such conditions as depression, addiction, and hyper-aggressiveness that are implicit in the behavioral-genetic revolution.
