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. Cattell used mainly the R and P technique of factor analysis. R technique, being the most common form, usually entails providing big groups of research participants varied personality tests & then inter-correlating their scores. The idea is to start with a huge number of surface variables (surface traits) and then to decrease them to fewer common source factors (source traits) which can predict the variation in surface-variable measures. Strongly inter-correlated variables are said to be measuring similar unit or factor. The investigators find it most difficult to label these factors and considerable skill and care is exercised in the labelling process as it has implications for theory and research. Once the inter- correlations have been computed, further factor-analytic calculations are used to get a factor matrix of factor loadings (degree of association between surface variable & its underlying factor). Once the tentative identification of factors is done, researchers usually attempt to use other samples (age, ethnic background) for cross validation and also place more tests into the analysis to discern new variables loading significantly on the same factor. P technique is intended to determine the unique trait structure of a particular person (Cattell, 1961, 1965). By testing the individual over and over again over a period of time on a number of personality traits and Cattell used it to appraise the alterations in individual motivations.

Raymond Cattell and his Approach to Personality 3.1 Biographical Account Raymond Bernard Cattell born in Hilltop, England, on March 20, 1905 as the second born to a mechanical engineer father. Cattell was an exceptional student winning scholarship to University of London. In 1924, he earned his Bachelor of Science degree with first-class honours in chemistry from Kings College. Soon his interests became more social & he dazed his well wishers by switching to the dubious subject of psychology. “My laboratory bench began to seem small, and the world’s problems vast. I concluded that to get beyond human irrationalities, I had to study the workings of the mind itself” (Cattell, 1974, p. 64). Cattell received his doctorate under Charles Spearman of the factor analysis fame from University of London in 1929. Cattell married thrice: an artist, Monica Campbell from 1930 to 1938 (one son); from 1946 to 1980 to a mathematician, Alberta Schuettler with whom he published numerous tests and articles and had three daughters and a son; and finally to a clinical psychologist, Heather Birkett. Cattell arrived in United States to work at Columbia University in 1937. Soon afterwards he shifted to Clark University in Massachusetts, and followed by Harvard. In 1945, he finally honoured a research professorship at University of Illinois and founded the Laboratory of Personality Assessment and stayed as director for 27 years. In 1978, he relocated to teach at the University of Hawaii. As one of the most ingenious personality theorists, Cattell’s writings comprise of hundreds of journal articles and around 56 books. Cattell’s honours include the New York Academy of Sciences’ Wenner–Gren Prize & Gold Medal Award for Life Achievement in Psychological Science from American Psychological Foundation. On February 2, 1998, Raymond Cattell passed away in Honolulu, Hawaii. 3.2 Cattell’s Approach to Personality 3.2.1 Personality Traits Cattell described traits as relatively permanent reaction tendencies serving the basic structural units of the personality. He classified traits in several ways. Table 1: Cattell’s Classification of Traits Types of Concept Example Traits Common trait possessed by everyone to some Intelligence, degree, a few persons possess them to a larger Extraversion degree in comparison to others as all persons Gregariousness Common have a comparable hereditary potential and are and subjected to like socio cultural norms and Unique Traits pressures.

He supposed that a personality theory is incomplete if it fails to consider the impact of dynamic motivating forces. It is akin to describing an engine but failing to cite the kind of fuel required. 2 kinds of dynamic, motivating traits: ergs and sentiments were proposed. Ergs and Sentiments: The phrase erg originates from Greek ergon referring to work or energy. Cattell utilized erg to indicate the notion of drive or instinct. Ergs are the driving force or intrinsic energy source for behaviours, the fundamental units of motivation steering us toward specific goals. 11 ergs being constitutional traits were identified Self- Anger Security Curiosity Sex Protection assertion Gregariousness Appeal Hunger Self-submission Disgust Sentiments are environmental-mold source traits as they originate from outer physical

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.

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.
