Here Hans Eysenck applies the principles of modern learning theory to account for the observed phenomena of hysteria and anxiety. Such principles were initially developed through the experiments and theories of Pavlov, Hull, and Tolman. When The Dynamics of Anxiety and Hysteria initially appeared, these were considered the most advanced, relevant, and applicable to the subject matter. They have not been superseded by later work. The Dynamics of Anxiety and Hysteria has never been published in the United States. It was the fifth book Eysenck authored as part of a series of experimental studies and theoretical work carried out under the auspices of the Institute of Psychiatry at the University of London. Two of the first four books-Dimensions of Personality and The Psychology of Politics, have been reissued with new introductions. These focus on dimensional analysis of personality based on experimental and empirical studies. The present work, on the other hand, goes beyond classification to a study of dynamics; from nosology to aetiology; from description to causation. Eysenck scientifically explores such topics as learning theory and human behavior, personality and learning theory; personality and perceptual processes, socialization and personality, drugs and personality, and psychological theory and psychiatric practice. This volume, which complements Transaction's other new editions of Eysenck's groundbreaking work, will be of lasting significance to psychologists, psychiatrists, behavioralists, and students of personality disorders. He provided for modern psychology the empirical foundations of themes that previosly were the monopoly of psychoanalysis. Hans J. Eysenck (1916-1997), a professor of psychology at the University of London and the director of its psychological department at the Institute of Psychiatry, was best known for his experimental researches in the field of personality. He was a prolific author and wrote, among others, Rebel with a Cause, Dimensions of Personality, and Intelligence, all available from Transaction.

The Report on Smoking and Health published by the Royal College of Physicians in England in 1965 warned of a connection between lung -cancer and smoking. The findings were widely publicized, and were accepted by practically every-one-indeed, they persist today. As Hans J. Eysenck shows in his classic study Smoking, Health, and Personality, the results were by no means immune to challenge. Not only were the experimental and statistical methods employed vulnerable to criticism, but the results were open to more than one interpretation.In this new edition, Stuart Brody reviews Eysenck's achievement. Eysenck critically reviewed the literature, presented longitudinal studies showing that psychological characteristics are far more potent predictors of heart disease and cancer than smoking behavior, and demonstrated that psychological treatment can halve death rates. Eysenck also spoke the unspeakable, iconoclastically attacking the cherished attribution of millions of deaths to smoking. He examined the interaction of smoking with personality and constitutional factors, and the connection between these factors and the development of cancer. Eysenck saw the cause-and-effect relation between cancer and smoking as oversimplification. He also makes a number of practical suggestions for the kind of social action that could be taken to decrease the incidence of lung cancer. For his part, Brody notes that massive campaigns which exhort people to eschew tobacco or cholesterol have had little or no demonstrable health benefits.This original and stimulating volume is written with great clarity and is easily understood by the layman. It is an incisive account of one of the most important social problems in this country today, and a challenge to orthodoxy in the medical world. As such, this volume offers much for both sides of the anti-smoking lobby, as well as those in the fields of psychology, political science, and sociology. .

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.

What is meant by the term "intelligence" and, once de- fined, how do we go about achieving a valid measurement of this faculty? This classic textbook, originally published in 1979, and now reissued with a new preface by Sybil Eysenck, incorporates a broad range of findings and reanalyzes much of the existing literature in this area. In The Structure and Measurement of Intelligence, Hans Eysenck draws on methods for determining the effect of genetics and environment on the development of intelligence and examines the validity of the term as defined in relation to internal as well as external criteria. He tests a number of hypotheses on intelligence against empirical research findings and considers various criticisms in detail. The significance of intelligence and its measurement in society are explored in depth. Eysenck greatly expands upon such questions as: Does IQ measure intelligence? How valid is the nature versus nurture argument? and, How might socioeconomic status influence one's intelligence? Designed primarily for students and scholars in psychology and education, this text will make thought-provoking reading for all concerned with the development and measurement of intelligence in the individual.

This classic is one of the most cited and novel approaches to psychology ever written. Hans Eysenck presents a descriptive and causal model of human personality in accord with the major concepts of experimental psychology and the physiological and neurological mechanisms that form the biological basis of behavior patterns. His proposal for an alliance between personality and physiology represented a major innovation in the field of psychology, distinguished his research from his contemporaries, and set the stage for a wealth of research to come. Before this foundational work, Eysenck had initially constructed a model of personality in such works as Dimensions of Personality and The Experimental Study of Personality, but these were primarily descriptive in nature. A second phase of research included his Dynamics of Anxiety and Hysteria and Experiments with Drugs, where he provided causal analysis by reference to concepts then current in experimental psychology. The Biological Basis of Personality represents Eysenck's third phase, when he dug deeper to find biological causes underlying the psychological concepts of emotion, excitation, and inhibition--which had formed the building blocks of his earlier efforts. In this work, the causal links he postulates between personality variables and neurological and physiological discoveries establish a realistic model that takes theory out of the field of mere speculation. As Sybil Eysenck makes clear in her new preface, this book paved the way for a "marriage" of the experimental and individual difference approach in personality psychology.

Hans Eysenck was one of the best-known research psychologists of the twentieth century. Respected as a prolific author, he was unafraid to address controversial topics. In Decline and Fall of the Freudian Empire, he places himself at the center of the debate on psychoanalytic theory, challenging the state of Freudian theory and modern-day psychoanalytic practice and questioning the premises on which psychoanalysis is based. In so doing, Eysenck illustrates the shortcomings of both psychoanalysis as a method of curing neurotic and psychotic behaviors, and of the theory of dreams and their interpretation. He also analyzes Freud's influence on anthropology and his alleged contributions to science.While books about Sigmund Freud and psychoanalysis abound, most have been written by followers and acolytes and are therefore uncritical, unaware of alternative theories, or written as weapons in a war of propaganda. Others are long and highly technical, and therefore valuable only to students and professionals. Decline and Fall of the Freudian Empire, on the other hand, was written with the non-professional in mind, and is for those who wish to know what modern scholarship has discovered about the truth or falsity of Freudian doctrines.Graced with an incisive new preface by Sybil Eysenck exploring her husband's motivation for writing the book, Decline and Fall of the Freudian Empire is an authoritative and convincing work that exposes the underlying contradictions in Freudian theory, as well as the limitations and errors of psychoanalysis.

Begun in 1938 and completed only in 1955, The Public Philosophy offers as much a glimpse into the private philosophy of America's premier journalist of the twentieth century as it does a public philosophy.The basis of Lippmann's effort is "that there is a deep disorder in our society which comes not from the machinations of our enemies and from the adversaries of the human condition but from within ourselves." He also provides a special sort of legacy to liberalism in its broadest sense - as the root approach to human existence that could provide civility and accommodation against incivilities and extremism, and that uniquely stood against the totalitarian counter-revolutions from Jacobism to Leninism. This work is a masterful defense of the public philosophy as a constitutional tradition, and can be easily read as such today.Paul Roazen, long identified with the analysis of Lippmann's work, points out that no matter how trenchantly Lippmann dissected democracy, and the populist faith in the people's wisdom, he still sought to study the world in order to help govern it. His constant flow of journalistic writing had the educative intent of raising the level of the public's knowledge. His rationalist conviction that clearheadedness on public matters can be effectively relayed to people is nowhere more evident than in The Public Philosophy. In this sense it is an argument for the democratic ideal that people can be rallied in defense of the public interest.

In The Social Consequences of Modern Psychology Eysenck takes the position that social science has real substance, and its findings ought to be applicable to social problems of our times. Although there is little that scientists can do about war and its prevention, or about social unrest and upheaval, or about strikes and other confrontations, there are a number of questions to which we can give tentative answers. This book deals with some of these questions, and finds some of the answers.

Eysenck begins with a look at a paradox of modern psychology. Experimental psychologists use strictly scientific methods to investigate what to many people seem trivial and sterile problems, yet some social psychologists, psychiatrists and psychoanalysts investigate what are clearly important and socially relevant problems, but use methods and theories whose scientific rigor is doubtful at best. This paradox is artificial and unnecessary. Methods of investigation and theories and concepts enable us to combine worthwhile problems and rigorous methods.

The book takes a long look at a particular problem which Eysenck investigated in depth during his illustrious lifetime. This tour de force, by one of the magisterial figures of modern psychology, is written for people as well as about people. It is not a rehash of the voluminous writings of lawyers, poets, politicians, dramatists, historians, psychiatrists and others who have felt compelled to write about these psychological matters without even a smattering of psychological knowledge. It is, instead, based on empirical investigations that are too often declared to be nonexistent by publicists and politicos.

The concept and measurement of intelligence present a curious paradox. On the one hand, scientists, fluent in the complex statistics of intelligence-testing theories, devote their lives to exploration of cognitive abilities. On the other hand, the media, and inexpert, cross-disciplinary scientists decry the effort as socially divisive and useless in practice. In the past decade, our understanding of testing has radically changed. Better selected samples have extended evidence on the role of heredity and environment in intelligence. There is new evidence on biology and behavior. Advances in molecular genetics have enabled us to discover DMA markers which can identify and isolate a gene for simple genetic traits, paving the way for the study of multiple gene traits, such as intelligence.

Hans Eysenck believes these recent developments approximate a general paradigm which could form the

basis for future research. He explores the many special abilities--verbal, numerical, visuo-spatial memory--that contribute to our cognitive behavior. He examines pathbreaking work on "multiple" intelligence, and the notion of "social" or "practical" intelligence and considers whether these new ideas have any scientific meaning. Eysenck also includes a study of creativity and intuition--as well as the production of works of art and science--identifying special factors that interact with general intelligence to produce predictable effects in the actual world.

The work that Hans Eysenck has put together over the last fifty years in research into individual differences constitutes most of what anyone means by the structure and biological basis of personality and intelligence. A giant in the field of psychology, Eysenck almost single-handedly restructured and reordered his profession. Intelligence is Eysenck's final book and the third in a series of his works from Transaction.

Hans Eysenck is one of the world's leading psychologists and undoubtedly the most controversial. Throughout a long and illustrious career his work on personality and intelligence has aroused impassioned debate and attacks, both verbal and physical, on Eysenck himself. In his compelling and absorbing autobiography, Eysenck recounts in some detail the battles he had to fight in order to establish his major conclusions, as well as the reasons why he investigated these subjects. He also discusses his work on such topics as the health hazards of smoking, the prophylactic effects of behavior therapy on cancer and coronary heart disease, parapsychology, astrology, and other matters. In a new foreword, written for this edition, Eysenck expresses his pleasure regarding the fact that his autobiography is now being published in the United States. He discusses how much of his scientific life has been bound up with American psychology. Also new to this American edition is a chapter titled "Genius, Creativity, and Vitamins," in which Eysenck talks about the research he has worked on since his retirement in 1983. Rebel with a Cause is an intriguing autobiography and will be of paramount interest to psychologists, sociologists, and genetic scientists.

This is a book on reminiscence, or more modestly a book on reminiscence in motor tasks, or more modestly still on reminiscence in pursuit rotor learning, with occasional references to other types of reminiscence. The vast majority of experiments investigating reminiscence with the pur suit rotor have been carried out within the framework of Hullian learn ing theory. Thus, of necessity, this book also will be much concerned with that theory. Some readers may feel that so much detailed attention paid to one piece of apparatus and one now rather discredited theory, is overdone; we could not agree with such an evaluation. There are several features of pursuit-rotor performance which make it particularly worthy of attention. One of the more important of these features is the easy replicability of many of the phenomena found in performance of this task; this is our first point. Replicability is the life blood of science; what cannot be replicated by any well-trained observer is of doubtful status in science, and on this score pursuit-rotor work certainly emerges as perhaps the most reliable set of observations in experimental psychology. The effects of massing and spacing; of rest pauses of different length; of switching from massed to spaced learn ing, or vice versa; of interpolating different activities; of introducing distracting stimuli; of switching from right to left hand, or vice versa; of changing the speed of rotation, or the diameter of the target disk these are clear-cut and replicable as few phenomena in psychology are."
