BF431.C345 1986 153.9 86-16606 ISBN 0-444-87922-6 (U.S.) PRINTED IN THE NETHERLANDS FOREWORD The nature and measurement of man’s abilities as a central pre- occupation of psychology had its day in the closing years of the last century and in the early decades of the present one. Unfortunately, the enterprise faltered, and interest declined as other aspects of psychology became more fashionable. Perhaps it is not entirely fair to say that interest in abilities went out of style but rather that the field stagnated, suffering from a paucity of new ideas and characterized by the persis- tence of out-moded concepts. Such a state feeds upon itself, for able psychologists are attracted elsewhere, leaving the arena to those willing to accept and live within parameters set by the past. However, times as well as fashions change. The events of the 1960s have radically modified the nature and direction of society, and with these changes have come corresponding alterations in the interests of behavioral scientists. One such change has been a recognition that a civilization has a duty to consider its human resources and to make the most of them, not only for the sake of the civilization itself but also for the benefit of the individuals and groups that comprise it. Modern society, taking its text from the Bible, is becoming increasingly “mindful of man” and looking for answers helpful in implementing its new programs. One resulting interest is in human abilities, as the reactions catalyzed by Arthur Jensen’s article in the Harvard Educational Review attest. The 1969 meeting at the University of Illinois considering the revision of contemporary intelligence concepts is reminiscent of a similar meeting held nearly fifty years earlier at Indiana University. The circle appears to be closing. The last quarter of the twentieth century may well see the study of human abilities regain both the prominence and the quality that characterized it in the first quarter of the century. And Raymond Cattell’s present volume is a giant step in that direction. A new book by Professor Cattell is a major publishing event because his works are invariably stimulating, unorthodox, and controversial ; one always senses a thrust into the future. Intelligence: Its Structure, Growth and Action is no exception. Cattell brings impeccable credentials of training, experience, and personal research to the task of writing a v vi Foreword definitive book on human abilities. Actually the volume deals almost entirely with intelligence, allotting relatively little space to motor and perceptual abilities or to occupational ability patterns. Professor Cattell ignores side issues that would distract the reader from a plan to give coherence and unity to the overall field of abilities. Many readers who know the Cattell of recent years as a psychologist concerned primarily with personality and motivation may wonder why he has selected the present topic. Yet Cattell’s pioneering work was in the field of intelligence, and it was he who developed and introduced culture-fair intelligence tests. Numerous research articles on intelligence and related topics, various intelligence scales, and such provocative concepts as fluid and crystallized intelligence attest to his eminent quali- fications and interest in the field. As a behavioral scientist Cattell contends that an understanding of the structure of intelligence must come mainly through the study and analysis of behavior, accomplished with cross reference to evidence from other cognate disciplines bearing upon the nature of man and his activities. His approach is holistic in that he demands the destruction of the artificial barriers erected by such restrictive categorizations as motiva- tion, personality, and intelligence. The fourteen chapters of the book take the reader from psychometric beginnings through discussion on the nature of abilities and their exemplifications. Chapters dealing with heredity and environment and with intelligence and society speak directly to those concerned with the worlds of today and tomorrow. Of special theoretical interest is the discussion of the triadic theory of abilities, particularly in terms of developmental relationships. Through- out the book, his references to his own work, stretching over forty highly productive years, illuminate the points he makes from direct personal experience. Few scholars can draw upon such a prodigious personal backdrop of research and writing - a backdrop consisting of some thirty books and over three hundred articles. Intelligence is a book to be read with profit by the untrained psycho- logist as well as by specialists in other fields relating to the nature of man and to programs designed to further his welfare. Research workers interested in intelligence and its social implications will find it of particular interest. This volume will not answer all possible questions about human abilities and their potential role in social planning. Not everyone will agree with the author’s formulations and conclusions. Yet Intelligence is unmistakably a milestone in a chaotic field, and, despite the highly technical nature of much of the subject matter, an imaginative Foreword vii contribution which will stimulate both antagonist and supporter to pursue the crucial task at hand. John E. Horrocks PREFACE This revised version of my work on Abilities, Their Structure, Growth and Action written in 1971 will be found to have essentially the same basis, but brought up to date by the events of recent years. In this work I have been aided by discussions with Dr. Arthur McKenna, whose practical experience in the field of physiology and anatomy of abilities brings a new emphasis to the present book. The main happenings in those years have been the extension of ability study to more qualitative observations, as in those by the followers of Piaget, and a consolidation of the findings about the distinction of fluid and crystallized intelligence, a good deal through the work of Vaughn, Horn and McArdle. In addition especially through the work of Nesselroade, Horn, Baltes and others at the Max Planck Institute we have attained a much more precise knowledge about the life curves of intelligence and their causes. In recent years my book on the inheritance of personality and ability appeared, which has added appreciably to our understanding of ability genetics. All in all, therefore, we feel that this book appears at a timely moment for the use of graduate students in particular, but of students and practitioners of all kinds. ix TABLES AND FIGURES Chapter One None Chapter Two Table 2.1.

Introduction Nomothetic trait models are obligated to Raymond Cattell, an eloquent proponent that key attributes of personality can be illustrated by discrete dimensions. Cattell’s theory of personality is inseparably connected to quantitative measurement models based on factor analysis of personality data through questionnaire responses and other sources. While Costa and McCrae attempted to stimulate the majestic proposal of Cattell’s idea- an empirical model of traits encompassing gamut of personality. Their Big Five model was focused on depiction of personality, not causes of personality. To study problems with multiple variables, Cattell stressed a great deal on the statistical tool of factor analysis which is used to segregate larger group of observed, interrelated variables to find out a limited number of underlying factors.

Powers PSY 201 12/13/13 Knowles 1 ABSTRACT Music is a universal phenomenon that is seen throughout every culture across the world. People have manifested individual interests in music based on their environment, culture, and distinct discernments. Music is easily accessible currently due to the media age that has dominated across the world; therefore individuality has never been so independent and universal at the same time. With that being said, an iPod can reveal a good amount of personal information about a person with the different types of musical genres they have acquired. The distinguishing factors of music can subsequently determine certain behaviors and traits the person can potentially possess. Research has determined that with certain music, there are collective traits the person is more disposed too. Therefore, there is a definite relationship between one’s music preference and personality. The theories, dimensions, research, arguments, and how to test the relationship will be exposed from this paper. Knowles 2 THEORIES Raymond Cattell was a trait theorist with the intent to study personality to predict how a person would behave in a certain situation (Schultz & Schultz, 2013).

  • History of the World (Of Psychometrics)
    history of the world (of psychometrics) ... AS SEEN BY AN ENLIGHTENED TRAVELLER Psychometrics: a branch of psychology which creates and studies theories, methods and techniques for evaluating and measuring an individual’s psychic capacity, using tests, inventories and other statistically valid techniques. It is always difficult to define a method or discipline’s origins in a precise manner. Psychometrics is no exception here. However, the subject is not neutral: by introducing the notion of measurement into the study of the human mind, psychometrics allows psychology to be differentiated from philosophy, from whence it came. The question of origins thus allows us to date the split between the two disciplines. 1573–1904: the origins of the discipline Several authors have debated the question of the origins of psychometrics. Greece, China, Egypt... and so on? The practice of evaluating and ranking of candidates or workers has emerged in various places at different times. Can we call this psychometrics already? Juan Huarte de San Juan, a Spanish doctor and philosopher (c 1530-1588), marks a true starting point. In 1573, he published his Examen de Ingenios para las Ciencias, or exam of the mind in sciences, which made its way progressively across Europe. It is the first ever tract that establishes a link between psychology and physiology. But it was the German philosopher Christian von Wolff (1679-1754) who is recognized as the first to have used the term “psychometrics”. In his 1732 work, Psychologia Empirica, in the note on paragraph 522, he writes: “in the dual way we have of building the foundations of degree of pleasure and pain, psychometrics comes to our rescue.

Objective • Students will be able to know about and understand the key concepts and the basic dimensions of personality described by Raymond B. Cattell. Learning outcome- The students would be able to draw the differences between the various types of traits used by Cattell in his personality theory. They would be able to understand that how do the concept of dynamic lattice helps people in evolving their personality in various situations. Cattell has used the concept of Factor analysis while identifying the various traits of personality. His theory has used factor analysis as an empirical tool while identifying theoretical concepts of traits. - The essential ideas of factor analysis were introduced by Spearman who is known for his work with mental abilities. - He defined that any two tests, which are related, identify two factors. One is a general factor and other is a specific factor. - General factor is common to both tests while specific factor is unique to each test. - By examining patterns of covariation, factor analysis allows us to take large number of data based upon different measures to be reduced to certain set of clusters or factors.

    Theories of Personality-II UNIT 2 RAYMOND CATTELL: A TRAIT THEORY OF PERSONALITY Structure 2.0 Introduction 2.1 Objectives 2.2 Cattell’s Trait Theory of Personality 2.2.1 The Formula for Personality 2.3 Categories of Traits 2.4 Role of Herdity and Environment 2.5 Constitutional versus Environmental –Mold Traits 2.6 Ability, Temperament and Dynamic Traits 2.7 Common versus Unique Traits 2.8 Let Us Sum Up 2.9 Unit End Questions 2.10 Glossary 2.11 Suggested Readings and References 2.0 INTRODUCTION Cattell’s theory seeks to explain the complicated transactions between the personality system and the more inclusive sociocultural matrix of the functioning organism. He suggested that an adequate theory of personality must take into account the multiple traits that comprise the personality, the extent to which these traits are genetically and environmentally determined, and the ways in which genetic and environmental factors interact to influence behaviour. He is also of the opinion that an appropriate theory of personality must take into account the multiple traits that comprise the personality, the extent to which these traits are genetically and environmentally determined, and the ways in which genetic and environmental factors interact to influence behaviour. In this unit we will be studying the details regarding Cattell’s Trait theory of personality, its definitions, the dynamics underlying the theory etc. 2.1 OBJECTIVES After completion of this unit, you will be able to: • Define Cattell’s theory of personality; • Describe the characteristic features related to trait theory; • Explain the various methods and measurement instruments of trait; • List out the categories of traits; and • Explain the functions of traits and their influence on personality.
