Cattell and the Big Five Factor Analytic Trait Theories Factor Analysis- the strength of these approaches is their description of personality through clearly defined factors, assessed through questionnaires. It offers clear operational definitions, so the theory is verifiable. Correlation coefficient measures the relationship between two sets of numbers. Positive correlations show high numbers in one factor related to high numbers in the second factor. Negative correlations show high numbers in one factor relate to low numbers in the second factor- an inverse correlation. The correlational coefficient ranges from +1.0 to 0 to -1.0, showing the strength and direction of relationship between factors. Correlation matrix is a computation of all pairs of variables. They often show redundancy, which can be described and categorized. Factor Analysis is the essential tool of factor analytic trait theories- a statistical procedure based on the concept of correlation. This techniques can describe large numbers of variable by identifying smaller numbers of dimensions- factors. It combines lots of detailed information about a person into more general trait statements. It was originally used to study aspects of intelligence by testing for various abilities and seeing related abilities. Factor analysis is a sophisticated mathematical tool for identifying patterns of related observations. The 16 Factor Theory: Cattell claimed that the study of personality passed through 2 earlier phases before reaching its current scientific status. 1. Intuitive insights expressed in literature and philosophy- Plutacrch, Bacon, Goethe. 2. Clinically oriented theorists- Freud, Adler, Jung, using some primitive experimental work 3. Experimental and quantitative stage developed since World War I (Since this time, the Big Five factor theory developed.) Biography o Born in England, Cattell was the son & grandson of engineers (easily seen in the influence on him in categorization & statistical analysis). He graduated from University of London and decided to get a graduate degree at King’s College in psychology. He learned Spearman’s factor analysis, which had been used to study intelligence up to that point. He first took a position as a school psychological service director. He married and had one child. But his work was so consuming that the marriage failed when Monica left him. He was developing a projective test similar to the one developed by Henry Murray. Cattell said he was probably first to use the term “Projective test.” He came to New York to work with E.L. Thorndike to work in social psychology, eventually migrating to the US and taking a professorship at Clark University, developing the Culture Fair intelligence test. He transferred to Harvard, working side by side with Allport, although their views on personality factors and testing were very different. During WWII he worked up objective personality tests for the military for officer selection. In 1945 he moved to University of Illinois, where he married again and had 4 children. He had a research appointment and a computer, so his explorations of multivariate statistical methods took off. He started the Institute for Personality and Ability Testing (IPAT) which is the source for buying any of the tests Cattell developed. He founded the Society for Multivariate Experimental Psychology to foster research in this area. He retired to Hawaii but stayed active in theory development and use of computers for research. He died in 1998. The year before he was given a lifetime achievement award from the APA for creating “a unified theory of individual differences integrating intellectual, temperamental, and dynamic domains of personality in the context of environmental and hereditary influences.” Personality: prediction of behavior o Cattell thought the theories regarding personality development to that time were simply speculations, bereft of any scientific underpinnings that could actually be used to make a prediction. Cattell defined personality as “that which permits a prediction of what a person will do in a given situation.” o Traits are the units of personality that have predictive value”: “that which defines what a person will do when faced with a defined situation.” They were conceptual tools useful for prediction, not particularly physical realities, like Allport thought. “Traits exist as determiners of behavior.” Measurement- Science is advanced by new tools. With the PET csan and MRI, we can understand the inner workings of organ systems in ways we could not before. Cattell insisted that personality tests themselves be tested to show reliability and validity in order that their findings be useful and dependable. Cattell refused to use the interview, saying there was too much bias inherent in the procedure. He preferred the Motivation Analysis Test. o Personality tests were the areas that Cattell was most effective in- he argued that a description of personality traits was essential if we would predict behavior. His best-known and most used test if the 16 Personality Factor Questionnaire. Some tests were even taken out of the big test for clinical use- the Neuroticism Scale, the Clinical Analysis Questionnaire, and the Marriage Counseling Report, measures of anxiety and depression. He also is well known for developing the Culture Fair Intelligence Test, which supposedly measures a person’s innate capacity to learn. o Beyond personality tests- Cattell looked for patterns of personality that could be confirmed by all three of these types of data. Confirmation of a trait across all three types of data increases your certainty that this is a meaningful personality trait. Q-data is information derived from subjects taking a pencil and paper test- questionnaires. Information can be distorted by subjects if they are trying to cover up aspects of their personality. T-data is objective test data- involving measuring instruments that are indirect, so the subject can’t know the purpose of the test. It includes projective test datainkblot tests, behavioral measures, reaction time,, blood pressure measurements. L-data is life record data- school records, grade point average, driving history, ratings at work, letters of recommendation. These are difficult to quantify, though. Personality is complex: the Multivariate Approach takes into account that people are affected by multiple influences and one must not oversimplify trait data. It is so complex, that without computers to keep track of data and analyze it, this level of investigation would not have been possible. Multivariate research methods incorporated several variables at one time to predict behavior. Traits are patterns of observations that go together. Surface traits and source traits o Surface traits are correlational clusters of variables that appear on the surface to be a trait, there is no evidence that they are an enduring trait. The pattern of correlations might not reappear in different circumstances. o Source traits are robust correlational clusters- they reappear over and over again, in spite of differences of population, situations; etc These traits must correspond to one cause with the personality- to be a fundamental trait of personality. Measurement of source traits: the 16PF Cattell developed questionnaires to measure the source traits as clearly as possible. The 16PF consists of 16 multiple choice scales, each measuring one underlying source trait. The profile of the person consists of the set of scores on all factors. Cattell even made up words to describe some factors: Premsia is derived from “protected emotional sensitivity” Five Second-Order Factors- second-order factor analysis reduced the 16 factors to 5 which are strikingly similar to the Big Five that McCrae and Costa have developed. Two of these are: o Extraversion which is characterized by strong liking for others, talkativeness, optimism, and adventurous boldness. It is believed to have strong heritability as the basis. Cattell also said the inherited tendency was to react more strongly to ideas than to external stimuli in introverts, and the opposite for extraverts. o Anxiety is also called Neuroticism and consists of ego weakness, guilt proneness, paranoid tendency, low selfsentiment and high drive tension. Psychological Adjustment levels can be derived from studying certain traits, such as Ego strength, low emotional stability, high sensitivity, high imaginativity, seriousness, and low dominance. Cattell suggested 3 particular factors were involved in emotional adjustment and self-control: ego strength, superego strength, and selfsentiment integration. Heredity plays a part in development of neurosis, but so does family conflict, inconsistent discipline, and insufficient affection. Psychoticism is more serious a condition than neurosis, showing a detachment from reality. Cattell found different patterns of traits for various diagnoses of mental illness. He developed clinical scales similar to the 16PF to focus on differences shown by different diagnostic groups. Three Types of Traits can be studied to understand the entire person: Ability traits relate to types of intelligence and motivation toward a goal. Heredity and learning affect this outcome. Cattell wanted to be able to test for innate intelligence, regardless of the nature of education the person had. So he distinguished 2 types of intelligence: o Fluid intelligence is the innate ability to learn. It is fluid because it is expressed in various kinds of learning, depending on the educational opportunities the person has. o Crystallized intelligence is the measurement of what has been learned through education. These test results are used to predict scores on Advanced Placement tests and tests of knowledge. This can continue to grow with age, if the person keeps himself active and continues to make efforts to learn new things. o Culture Fair Intelligence Test was developed to measure only fluid intelligence, so as to better recognize the abilities of those who have had poor or nonexistent education. Even so, experience does influence scores, so it is hard to say it is completely free of cultural/ educational influence. Cattell examined many kinship studies to determine the heritability of intelligence and decided 80% of intelligence is inherited. Unfortunately he decided that this formed the basis of a rationale for a eugenics movement designed to eradicate the minority people who were thought to have lower intelligence and would reproduce at a high rate, bringing down the intelligence of the whole society. (Aboriginal policies in Australia, justification for Nazi eradication of many peoples) The truth was found that intelligence increased over the generations, did not decline as feared. This argument resurfaces from time to time even today, as justification for dropping educational support programs for disadvantaged youth (The Bell Curve) Temperament traits are inherited source traits that determine the general style with which a person carries out what s/he does. It is also a group of characteristics that are highly heritable, as found in twins separated at birth. Dynamic traits are motivational- they give energy and direction to action. He believed some motivations were innate and others were learned. Ergs were innate; metaergs were learned motivations. o Ergs are innate motivational traits. They are related to instincts as found in animals- innate reactions toward a goal, even though means may be learned. Ergs include anger, curiosity, fear, greed, hunger, loneliness, pity, pride, sensuousness, and sex. Genetics may serve to vary the level of an ergic trait, as well as the way the trait is channeled into behavior. One person seeks security through force, another through legal protections or financial planning. o Metaergs are the learned patterns that ergs get channeled into. Cattell thought of them as environmental-mold dynamic source traits (learned motivations.) They can be general- patriotism, values around education, or specific- opposition to a particular candidate. Sentiments are general metaergs. They are deep underlying motivations that form early and endure. These may be feelings about home, family, religion, country. The most important sentiment is the self-sentiment- a master motive. These are central to the personality. Attitudes are specific responses to situations. They are an interest in a course of action in any given situation. (Wanting to spend Thanksgiving with the family.) They are very specific, and useful to know so as to know how a broader dimension of personality would be expressedlove of country may be expressed in voting, getting involved in political campaigns, writing letters to editor, or sending letter bombs to people you find distasteful. Subsidiation – this is the process of channeling basic drives (ergs) into purposive activities. This requires learning. It takes a series of acts to complete a goal and we must learn the sequences to the goal. These are means-end activities- the instrumental goals along the way to achieving the main goal. The Dynamic Lattice is a diagram of subsidiation relationships. Attitudes are on the left, and are subsidiary to sentiments, in the middles which are subsidiary to ergs on the right. There are multiple connections among these motivational levels. Metaergs (attitudes and sentiments) are learned. Their connections with each other are affected by learning. As we develop these connections change. Ergs are generally satisfied indirectly through metaergs. Confluence learning is learning a behavior that can satisfy many motivations. These involve coordinating several traits, as well. So learning a foreign language well can open many opportunities to you for varied jobs, as well as foreign travel and prestige. Predicting Behavior The Specification Equation is Cattell’s engineering/ statistical approach to quantifying the human personality in order to predict behavior. According to Cattell, all behavior can be predicted using this obtuse and boring equation. Just know what the purpose is. Forms of this equation are used to predict the potential success of applicants to college from their GPA, SAT scores, letters of recommendation, etc. Where the formula breaks down is in quantifying all the situations that people face. Even the environment cannot completely be measured, as what really must be measured is the person’s psychological environment or life space- one’s perception of one’s environment. This equation assumes that each person’s traits are stable, but more recent research shows that traits are easily overcome by certain environments, so they aren’t as stable as first thought. Nomothetic & Idiographic Approaches: o R-Technique o P-Technique Syntality Determinants of Personality: Heredity and Environment Constitutional traits Environmental-mold traits MAVA – the Multiple Abstract Variance Analysis Heritability The Role of Theory in Cattell’s Empirical Approach- Cattell has been accused of being atheoretical, just doing empirical work blindly and predicting without a guiding theory. He claimed his models are theory and his statistical methodology could answer complex questions regarding human personality. He was very suspicious of theory that was built before any data was acquired (as Freud did.) His techniques did result in many discoveries in a briefer time than alternative approaches. The Five Factor Theory: McCrae and Costa tried to activate the grand scheme of Cattell’s vision- an empirically supported model of traits that encompasses the full spectrum of personality. Their Big Five model was focused on description of personality, not divining the causes of personality. The Big Five theory asserts that there are 5 basic factors of personality. They were developed from factor analysis of words people use for personality descriptors- the lexical approach similar to Allport going through the dictionary listing all 17,000+ words for traits. The Big Five consist of 5 broad personality traits: “OCEAN”: extraversion, agreeableness, neuroticism, conscientiousness, openness. A self-report questionnaire has been developed to measure these factors- the NEO-PI. The Big Five o Extraversion is also called dominance-submissiveness, or surgency (Cattell). Talkativeness, passion, activity, dominance, sociability. Introversion is quite, less expressive, passivity. Extraverts value excitement and fun, many social contacts, as well as having control. They are judged friendlier, fun-loving, and affectionate. They are more willing to have sexual contact without commitment, and they have more sexual contacts than introverts. They make friends more quickly than introverts. One facet of extraversion, low shyness, also predicts falling in love more easily. They seem happier and they may be programmed to respond more intensely to pleasure than less extraverted people. o Agreeableness consists of traits like good-natured, softhearted, trusting, as opposed to low agreeableness as seen in irritability, ruthlessness, suspiciousness. It is also called Social adaptability or Likability. High agreeableness personalities tend to avoid hostility and go along with others. Those low in this trait are suspicious, and uncooperative. High Agreeableness people report they value being helpful, forgiving, and loving. They report little conflict in their relationships and when it happens, their self-esteem is affected negatively. Men are more likely to use power to get their way or resolve conflict, even if they score high in agreeableness. There is a general avoidance of conflict in people high in agreeableness. It may or may not serve them well in the long run. o Neuroticism consists of worrying, emotionality, vulnerability, anxiety. Persons low in this trait are calm, less emotional, hardy, self-controlled, and generally feel a sense of well-being. Those low on neuroticism have Emotional Stability, emotional control, and ego strength. Those who are low on neuroticism are happier and more satisfied with life than those who score high. Neurotics are unhappy and dissatisfied with life. They have difficulties in relationships and commitment and often suffer low self-esteem. They also report more negative events with family and friends, leisure and finance. o Conscientiousness includes hardworking, ambitiousness, and responsibility. People low in consciousness are negligent, lazy, aimless, irresponsible. Conscientiousness includes dependability, impulse control and will to achieve, as well as orderliness and self-discipline. People high in this trait are organized, punctual, ambitious. They are generally motivated to achieve and students get higher grades in school. They are rewarded with high self-esteem. They also show higher job satisfaction, income, and status. They set and achieve higher goals, get better evaluations from bosses, and are generally satisfied with their lives. They have better attendance records. In family relationships and health, these people are less susceptible to sexual infidelity than those low in conscientiousness. Women are more likely to have a regular mammogram. o Openness has to do with openness to novel or interesting life experiences. It includes creativity, imagination, need for variety in life. People lower in openness are less creative, down-toearth, preferring routines. People high in this trait value imagination, broadmindedness and esthetics, beauty. People low in Openness value cleanliness, obedience, and national security. Openness is conducive to personal growth. These people are more creative and better problem solvers in many ways. A final word – the five factors consist of components, facets that can be measured separately. Each facet is more precise and focused trait than the larger factor, but all the facets are positively correlated with one another. We want to understand and recognize facets that go with certain factors, to protect ourselves or enhance our dominance in the tribe. One connection to extraversion is social dominance. We use this information to form alliances, cooperate in service to a goal, and in finding appropriate mates. The Big Five factors have been confirmed in the California Personality Inventory, the Eysenck Personaliyt Inventory, and the Myers-Briggs Type Inventory. The traits found are relatively stable over life and can be used to predict adjustment.
