This is the original work on which Hans Eysenck's fifty years of research have been built. It introduced many new ideas about the nature and measurement of personality into the field, related personality to abnormal psychology, and demonstrated the possibility of testing personality theory experimentally. The book is the result of a concentrated and cooperative effort to discover the main dimensions of personality, and to define them operationally, that is, by means of strictly experimental, quantitative procedures. More than three dozen separate researches were carried out on some 10,000 normal and neurotic subjects by a research team of psychologists and psychiatrists. A special feature of this work is the close collaboration between psychologists and psychiatrists. Eysenck believes that the exploration of personality would have reached an advanced state much earlier had such a collaboration been the rule rather than the exception in studies of this kind. Both disciplines benefit by working together on the many problems they have in common. In his new introduction, Eysenck discusses the difficulty he had in conveying this belief to scientists from opposite ends of the psychology spectrum when he first began work on this book. He goes on to explain the basis from which Dimensions of Personality developed. Central to any concept of personality, he states, must be hierarchies of traits organized into a dimensional system. The two major dimensions he posited, neuroticism and extraversion, were in disfavor with most scientists of personality at the time. Now they form part of practically all descriptions of personality. Dimensions of Personality is a landmark study and should be read by both students and professionals in the fields of psychiatry, psychology, and sociology.

This book is the first to bring together researchers in individual differences in personality and temperament to explore whether there is any unity possible between the temperament researchers of infancy and childhood and the major researchers in adult personality. Prior to the workshop which resulted in this volume, the existing literature seemed to document a growing consensus on the part of the adult personality researchers that five major personality dimensions -- the "Big Five" -- might be sufficient to account for most of the important variances in adult individual differences in personality. In contrast to this accord, the literature on child and infant individual differences seemed to offer a wide variety of opinions regarding the basic dimensions of difference in personality or temperament. The editors believed that they could encourage researchers from both the adult and child areas to consider the importance of a lifespan conceptualization of individual differences by discussing their research in terms of a continuity approach. Written by some of the most distinguished scholars from Great Britain, continental Western Europe, and Eastern Europe as well as the United States and Canada, the chapters present a cross-cultural view of both adult personality and temperament in infancy and childhood. By sharing their recent data, techniques, and theoretical speculations, the chapter authors communicate the research enthusiasm engendered by the growing consensus of the adult "Big Five" as well as the exciting prospects of an integrative program of research from infancy to adulthood that will clarify and consolidate what is now a disparate set of methods, theory, and findings across the lifespan. The editors suggest that this volume will have considerable heuristic value in stimulating researchers to conceptualize their work in developmental, lifespan approaches that will lead to a consolidation of individual differences research at every age.

In this groundbreaking handbook, more than 60 internationally respected authorities explore the interface between intelligence and personality by bringing together a wide range of potential integrative links drawn from theory, research, measurements, and applications.

The Personality Puzzle explores the past, present, and future of the discipline to show students why personality psychology matters.

The “H” in the H factor stands for “Honesty-Humility,” one of the six basic dimensions of the human personality. People who have high levels of H are sincere and modest; people who have low levels are deceitful and pretentious. It isn’t intuitively obvious that traits of honesty and humility go hand in hand, and until very recently the H factor hadn’t been recognized as a basic dimension of personality. But scientific evidence shows that traits of honesty and humility form a unified group of personality traits, separate from those of the other five groups identified several decades ago. This book, written by the discoverers of the H factor, explores the scientific findings that show the importance of this personality dimension in various aspects of people’s lives: their approaches to money, power, and sex; their inclination to commit crimes or obey the law; their attitudes about society, politics, and religion; and their choice of friends and spouse. Finally, the book provides ways of identifying people who are low in the H factor, as well as advice on how to raise one’s own level of H.

Personality is now understood to be a function of both biological and environmental influences. This revised and updated edition of Psychobiology of Personality describes what is currently known about the biological basis of the primary personality traits, including genetic, neurological, biochemical, physiological, and behavioral influences. Emphasis is placed on understanding the connections between phenomena at these levels. The research discussed makes use of animal models, based on experimental brain research, as well as human clinical and normal personality research. Chapters are devoted to temperament and personality trait structure, psychobiological methods, and each of four major personality traits: extraversion, impulsive, sensation seeking, and aggression. Recent advances in psychobiological methods, such as molecular genetics and brain imaging have enabled us to begin to unravel the genetic and neurological sources of behavior and personality. These advances are discussed in this new edition, making it essential reading for advanced students of psychology and psychiatry.
