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.

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.

The title that the authors have chosen for this book, The Causes and Cures of Criminality, suggests that it may be just another book specu lating on the sociological evils that need to be put right for "everything in the garden to be lovely." If this is the expectation, the reader could not be more mistaken. The recurrent theme, in fact, is a strong accent on psychological experiments. Both authors have tackled the theoretical and practical side of crime through an exhaustive literature review of past experi mental work. Hans J. Eysenck has concentrated on the constitutional and biological theory of criminality, whereas Gisli Gudjonsson has con cerned himself more with a review of ongoing research into therapy and possible prevention of antisocial behavior. Part I goes into considerable detail on the causes of criminality, stressing much of the strangely neglected area of individual differences in personality. Research studies point to a very heavy involvement of heredity in the causation of criminality, but the authors are careful to acknowledge that much can be done environmentally to discourage a life of crime once those persons who are at risk have been identified.

Jung, Sigmund Freud, Jean Piaget, Otto Rank, James Hillman, Erich Fromm, Karen Horney and Susan Isaacs. Each volume is available on its own, as part of a themed mini-set, or as part of a specially-priced 204-volume set. A brochure listing each title in the International Library of Psychology series is available upon request.

In writing The Psychology of Politics, Hans Eysenck had two aims in mind: to write a book about modern developments in the field of attitude studies which would be intelligible to the layman; and one that would integrate into one consistent theoretical system a large number of contributions on the topic from different fields. Eysenck believes that science has something to say about such problems as anti-Semitism, the origin and growth of fascist and communist ideologies, the causal determinants of voting behavior, the structure of opinions and attitudes, and the relationship between politics and personality. He seeks to rescue these factual findings from the obscurity of technical journals and present them in a more accessible form. The research presented in this book outlines the main principles of organization and structure in the field of attitudes. These principles account in a remarkably complete and detailed manner for the systems of political organization found in Great Britain, that is, the Conservative, Liberal, and Socialist parties, and the communist and fascist groups. Next, Eysenck relates these principles to the system of personality structure which for many years formed the main focus of research activity at the Institute of Psychiatry in London. The Psychology of Politics integrates attitude research with modern learning theory. In his new introduction, Eysenck writes that his research and personal experiences in Germany led him to believe that authoritarianism could appear equally well on the left as on the right. He saw Stalin as equally authoritarian as Hitler, and communism as equally totalitarian as Nazism. The Psychology of Politics contains the evidence and arguments Eysenck used to demonstrate his approach. This volume is of enduring significance for psychologists, political theorists, and historians. It is by indirection a major statement in modern liberalism.

Psychology.

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.
