Cattell and Eysenck

Usually when we talk about someone's personality, we are talking about what makes that person different from other people, perhaps even unique. â€Å"The Cattell and Eysenck constructs and theories should be seen, not as mutually contradictory, but as complementary and mutually supportive. † The Late Hans Eysenck (1984). Cattell and the theory of Personality. Mult. Behav. Res, 19, 323-336. This eight page report discusses the work and models created by Hans Eysenck (1916-1997) and Raymond Cattell (1905-1998). Each developed specific theories regarding human personality. Eysenck’s is best expressed in the Eysenck Personality Inventory (EPI) while Cattell’s 16PF or Sixteen Personality Factor Questionnaire serves as the best representation of his work on personality. Raymond Bernard Cattell (20 March 1905 – 2 February 1998) was a British and American psychologist known for his exploration of a wide variety of substantive areas in psychology. These areas included: the basic dimensions of personality and temperament, a range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of personality, patterns of group and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many scientific research methods for exploring and measuring these areas. Cattell was famously productive throughout his 92 years, authoring and co-authoring over 50 books and 500 articles, and over 30 standardized tests. According to a widely-cited ranking, he was the 16th most influential and eminent psychologist of the 20th century. Cattell and Eysenck 3 Raymond Cattell and Hans Eyseneck, so prominent were these two men, that their work is now enshrined in the Cattellian and Eysenckian Schools of Psychology, respectively. Cattell's scholarly training began at an early age when he was awarded admission to King's College at Cambridge University where he graduated with a Bachelor of Science in Chemistry in 1926 (Lamb, 1997). According to personal accounts, Cattell's socialist attitudes, paired with interests developed after attending a Cyril Burt lecture in the same year, turned his attention to the study of psychology, still regarded as a philosophy (Horn, 2001). Following the completion of his doctorate studies of psychology in 1929 Cattell lectured at the University at Exeter where, in 1930, he made his first contribution to the science of psychology with the Cattell Intelligence Tests (scales 1, 2, and 3). During fellowship studies in 1932, he turned his attention to the measurement of personality focusing of the understanding of economic, social and moral problems and how objective psychological research on moral decision could aid such problems (Lamb, 1997). Cattell's most renowned contribution to the science of psychology also pertains to the study of personality. Cattell's 16 Personality Factor Model aims to construct a common taxonomy of traits using a lexical approach to narrow natural language to standard applicable personality adjectives. Though his theory has never been replicated, his contributions to factor analysis have been exceedingly valuable to the study of psychology. In order to apply factor analysis to personality, Cattell believed it necessary to sample the widest possible range of variables. He specified three kinds of data for comprehensive sampling, to capture the full range of personality dimensions: Cattell and Eysenck 4 Objective, life data (or L-data), which involves collecting data from the individual’s natural, everyday life behaviors, measuring their characteristic behavior patterns in the real world. This could range from number of traffic accidents or number of parties attended each month, to grade point average in school or number of illnesses or divorces. Experimental data (or T-data) which involves reactions to standardized experimental situations created in a lab where a subject’s behavior can be objectively observed and measured. Questionnaire data (or Q-data), which involves responses based on introspection by the individual about their own behavior and feelings. He found that this kind of direct questioning often measured subtle internal states and viewpoints that might be hard to see or measure in external behavior. In order for a personality dimension to be called â€Å"fundamental and unitary,† Cattell believed that it needed to be found in factor analyses of data from all three of these domains. Thus, Cattell constructed personality measures of a wide range of traits in each medium. He then repeatedly performed factor analyses on the data. With the help of many colleagues, Cattell's factor-analytic studies continued over several decades, eventually producing 16 fundamental factors underlying human personality. He decided to name these traits with letters (A, B, C, D, E†¦), like vitamins, in order to avoid misnaming these newly discovered dimensions, or inviting confusion with existing vocabulary and concepts. Factor-analytic studies by many researchers in diverse cultures around the world have re-validated the number and meaning of these Cattell and Eysenck 5 traits. This international confirmation and validation established Cattell’s 16 factors as objective and scientific. Cattell set about developing tests to measure these traits across different age ranges, such as The 16 Personality Factor Questionnaire for adults, the Adolescent Personality Questionnaire, and the Children’s Personality Questionnaire. These tests have now been translated into many languages and validated across different cultures. Hans Eysenck was born in Germany on March 4, 1916. His parents were actors who divorced when he was only two, and so Hans was raised by his grandmother. He left there when he was 18 years old, when the Nazis came to power. As an active Jewish sympathizer, his life was in danger. In England, he continued his education, and received his Ph. D. in Psychology from the University of London in 1940. During World War II, he served as a psychologist at an emergency hospital, where he did research on the reliability of psychiatric diagnoses. The results led him to a life-long antagonism to main-stream clinical psychology. After the war, he taught at the University of London, as well as serving as the director of the psychology department of the Institute of Psychiatry, associated with Bethlehem Royal Hospital. He has written 75 books and some 700 articles, making him one of the most prolific writers in psychology. Eysenck retired in 1983 and continued to write until his death on September 4, 1997. This aspect of personality is called individual differences. For some theories, it is the central issue. These theories often spend considerable attention on things like types and traits and tests with which we can categorize or compare people: Some people are neurotic, others are not; some people are more introverted, others more extroverted; and Cattell and Eysenck 6 so on. However, personality theorists are just as interested in the commonalities among people. What, for example, do the neurotic person and the healthy person have in common? Or what is the common structure in people that expresses itself as introversion in some and extroversion in others? If you place people on some dimension – such as healthy-neurotic or introversion-extroversion – you are saying that the dimension is something everyone can be placed on. Whether they are neurotic or not, all people have a capacity for health and ill-health; and whether introverted or extroverted, all are â€Å"verted† one way or the other. Another way of saying this is that personality theorists are interested in the structure of the individual, the psychological structure in particular. How are people â€Å"put together;† how do they â€Å"work;† how do they â€Å"fall apart. † Some theorists go a step further and say they are looking for the essence of being a person. Or they say they are looking for what it means to be an individual human being. The field of personality psychology stretches from a fairly simple empirical search for differences between people to a rather philosophical search for the meaning of life! Perhaps it is just pride, but personality psychologists like to think of their field as a sort of umbrella for all the rest of psychology. Critics of the psychology of individual differences have often claimed naively that the use of factor analysis in test construction has â€Å"only lead to confusion–since Eysenck found three factors, while Cattell found 16 factors† within the personality domain. Yet these ill-informed critics failed to understand that Eysenck and Cattell were talking about personality measurement at different levels within the hierarchical trait model. Cattell and Eysenck 7 Ray concentrated on primary factors, while Hans focused on broader secondary dimensions. Indeed, at the second-order 16PF level, the degree of communality between the Eysenckian and Cattellian factors was striking! It might be nice to start off with a definition of theories of personality. First, theory: a theory is a model of reality that helps us to understand, explain, predict, and control that reality. In the study of personality, these models are usually verbal. Every now and then, someone comes up with a graphic model, with symbolic illustrations, or a mathematical model, or even a computer model. But words are the basic form. Different approaches focus on different aspects of theory. Eysenck’s theory is based primarily on physiology and genetics. Although he is a behaviorist who considers learned habits of great importance, he considers personality differences as growing out of our genetic inheritance. He is, therefore, primarily interested in what is usually called temperament. Eysenck is also primarily a research psychologist. His methods involve a statistical technique called factor analysis. This technique extracts a number of â€Å"dimensions† from large masses of data. For example, if you give long lists of adjectives to a large number of people for them to rate themselves on, you have prime raw material for factor analysis. Imagine, for example, a test that included words like â€Å"shy,† â€Å"introverted,† â€Å"outgoing,† â€Å"wild,† and so on. Obviously, shy people are likely to rate themselves high on the first two words, and low on the second two. Outgoing people are likely to do the reverse. Factor analysis extracts dimensions – factors – such as shy outgoing from the mass of information. The Cattell and Eysenck 8 researcher then examines the data and gives the factor a name such as â€Å"introversion-extraversion. † There are other techniques that will find the â€Å"best fit† of the data to various possible dimensions, and others still that will find â€Å"higher level† dimensions – factors that organize the factors, like big headings organize little headings. Eysenck's original research found two main dimensions of temperament: neuroticism and extraversion introversion. Neuroticism is the name Eysenck gave to a dimension that ranges from normal, fairly calm and collected people to one’s that tend to be quite â€Å"nervous. † His research showed that these nervous people tended to suffer more frequently from a variety of â€Å"nervous disorders† we call neuroses, hence the name of the dimension. But understand that he was not saying that people who score high on the neuroticism scale are necessarily neurotics – only that they are more susceptible to neurotic problems. His second dimension is extraversion-introversion. By this he means something very similar to what Jung meant by the same terms, and something very similar to our common-sense understanding of them: Shy, quiet people â€Å"versus† out-going, even loud people. This dimension, too, is found in everyone, but the physiological explanation is a bit more complex. Eysenck hypothesized that extraversion-introversion is a matter of the balance of â€Å"inhibition† and â€Å"excitation† in the brain itself. These are ideas that Pavlov came up with to explain some of the differences he found in the reactions of his various dogs to stress. Excitation is the brain waking itself up, getting into an alert, learning state. Inhibition is the brain calming itself down, either in the usual sense of relaxing and going to sleep, or in the sense of protecting itself in the case of overwhelming stimulation. Cattell and Eysenck 9 To bring to a close, although Cattell contributed much to personality research through the use of factor analysis his theory is greatly criticized. The most apparent criticism of Cattell's 16 Personality Factor Model is the fact that despite many attempts his theory has never been entirely replicated. In 1971, Howarth and Brown's factor analysis of the 16 Personality Factor Model found 10 factors that failed to relate to items present in the model. Howarth and Brown concluded, â€Å"that the 16 PF does not measure the factors which it purports to measure at a primary level (Eysenck & Eysenck, 1987) Studies conducted by Sell et al. (1970) and by Eysenck and Eysenck (1969) also failed to verify the 16 Personality Factor Model's primary level (Noller, Law, Comrey, 1987). Also, the reliability of Cattell's self-report data has also been questioned by researchers (Schuerger, Zarrella, & Hotz, 1989). Cattell and colleagues responded to the critics by maintaining the stance that the reason the studies were not successful at replicating the primary structure of the 16 Personality Factor model was because the studies were not conducted according to Cattell's methodology. However, using Cattell's exact methodology, Kline and Barrett (1983), only were able to verify four of sixteen primary factors (Noller, Law & Comrey, 1987). In response to Eysenck's criticism, Cattell, himself, published the results of his own factor analysis of the 16 Personality Factor Model, which also failed to verify the hypothesized primary factors (Eysenck, 1987). Despite all the criticism of Cattell's hypothesis, his empirical findings lead the way for investigation and later discovery of the ‘Big Five' dimensions of personality. Fiske (1949) and Tupes and Christal (1961) simplified Cattell's variables to five recurrent Cattell and Eysenck 10 factors known as extraversion or surgency, agreeableness, consciousness, motional stability and intellect or openness (Pervin & John, 1999). Cattell's Sixteen Personality Factor Model has been greatly criticized by many researchers, mainly because of the inability of replication. More than likely, during Cattell's factor analysis errors in computation occurred resulting in skewed data, thus the inability to replicate. Since, computer programs for factor analysis did not exist during Ca ttell's time and calculations were done by hand it is not surprising that some errors occurred. However, through investigation into to the validity of Cattell's model researchers did discover the Big Five Factors, which have been monumental in understanding personality, as we know it today. In summary, Humanists and Existentialists tend to focus on the understanding part. They believe that much of what we are is way too complex and embedded in history and culture to â€Å"predict and control. † Besides, they suggest, redacting and controlling people is, to a considerable extent, unethical. Behaviorists and Freudians, on the other hand, prefer to discuss prediction and control. If an idea is useful, if it works, go with it! Understanding, to them, is secondary. Another definition says that a theory is a guide to action: We figure that the future will be something like the past. We figure that certain sequences and patterns of events that have occurred frequently before are likely to occur again. So we look to the first events of a sequence, or the most vivid parts of a pattern, to serve as our landmarks and warning signals. A theory is a little like a map: It isn't the same as the countryside it describes; it certainly doesn't give you every detail; it may not even be terribly accurate. But it does provide a guide to action.

How to Face Resistance to Change

Resistance to change can be difficult to overcome even when it is not detrimental to those concerned. But the attempt must be made. The first step is to analyze the potential impact of change by considering how it will affect people in their jobs. The analysis should indicate which aspects of the proposed change may be supported generally or by specified individuals and which aspects may be resisted. So far as possible, the potentially hostile or negative reactions of people should be identified, taking into account all the possible reasons for resisting change listed above. It is necessary to try to understand the likely feelings and fears of those affected so that unnecessary worries can be relieved and, as far as possible, ambiguities can be resolved. In making this analysis, the individual introducing the change, who is sometimes called the ‘change agent’, should recognize that new ideas are likely to be suspect and should make ample provision for the discussion of reactions to proposals to ensure complete understanding of them. Involvement in the change process gives people the chance to raise and resolve their concerns and make suggestions about the form of the change and how it should be introduced. The aim is to get ‘ownership’ – a feeling amongst people that the change is something that they are happy to live with because they have been involved in its planning and introduction – it has become their change. Communications about the proposed change should be carefully prepared and worded so that unnecessary fears are allayed. All the available can be used, but face-to-face communications direct from managers to individuals or through a team briefing system are best.

Consumer Durables and Nondurables

Analysis The definition of consumer durables and nondurables Consumer durables involve many kinds of products that is purchased by consumers, it is manufactured for long-term use. Such as: car, furniture and so on. But consumer nondurables are opposite. It is expendable goods purchases by consumers for their daily or short-term use. Such as: clothing, shoes and so on. The characteristics of consumer purchase Because of consumer durables has long-term use, and comparing with consumer nondurables, price is higher, so consumer purchase behavior is more cautious. There are some reasons. First of all, much more selectivity cause consumers are hard to make decision. Secondly, because of there are a lot of different brand, so they will carefully compare the various brands of cost performance, generally, consumer focus on the quality, service, and brand reputation. Finally, consumers can not buy from nearest store, they are willing to go to large scale shopping malls. But consumer nondurable is opposite. There are some features of consumer nondurables. Because of nondurables goods are short-term use, it can be daily product, such as towels, soap and so on, so consumer is willing to buy those at nearest store. Also, it can be visual product, when consumer decide to buy it, they might be affected by packing and store’s ambience, which means consumer can make decision easily. On the other hand, consumer has less loyalty for brand, they usually change same product with different brand. So we can sum up some features about consumer purchase habit, which are easy, fast, impulsive and emotional. Main characteristics of market Consumer durables: For product advertising strategy, company usually focus on product exhibition and display as much as possible, also they must have a large scale warehouse for inventory Consumer nondurables: For advertising strategy, Company is willing to choose outdoor billboards in the down and some crowded place, or promote on the internet. They don’t need large size warehouse for inventory.

Book Report - Essay Example Her failure to manage the employees would lead to cutting off some jobs of her current employees. This thought of managing the employees has been portrayed in the book as a very daunting task and she gets some idea of managing those employees once she visits the Fish Market in Seattle. The Fish Market, known as Pike Place Fish Market, in Seattle, seems to be the focal place in the book and it is that particular area where Mary witnesses the fish mongers to work in a jolly atmosphere and serving their customers with great sincerity. The fish mongers throw the fish at other fish guys, some of them are caught by them whilst some are dropped. This catching and fumbling is hugely entertaining for the crowd, the customers and the fish guys. Each catch is praised by either the crowd or some staff guy whilst any drops are treated sarcastically or with humour. All these events at the Fish Market made Mary Jane realise that there were two ways of doing any work, one being to conduct and finish of your work in good mood or to finish of your work with bad temperament. The main scope of this book was to identify that work has to be done by each and every employee. Hence it is upon that particular employee to do it with the frame of mind that he has. The main aspect of improving work at any particular job is to choose the right attitude towards the work. The four key concepts that Mary Jane derived from this encounter at the Fish Market were: The meaning of this concept is that the work performed by any individual at work should be in such a manner that it should promote his interest in the work i.e. as if he is playing at work. Each and every activity conducted should be done with fun and high energy. This means that employees should create a great bond amongst them i.e. every activity should be carried with team work and great aspiration. This activity helps in building a better and great team in any working atmosphere. As explained above, this means that each and

Occupational Asthma Essay Example | Topics and Well Written Essays - 5250 words

Occupational Asthma - Essay Example OA is a disease characterized by variable obstruction of airflow and/or airway hyperresponsiveness attributable to factors associated with the workplace rather than to stimuli found outside that environment. (Nicholson, 2002) This requires a period of time for sensitization to the causative agent to develop, and therefore, there is a latent period between exposure and the appearance of symptoms. The following subtypes are distinguished according to the substances responsible for causing the disease: - Immunologic OA caused by high molecular weight substances. This usually occurs via an immunologic mechanism involving immunoglobulin (Ig) E. - Immunologic OA caused by low molecular weight substances. In this case, there is generally no clear involvement of IgE. (Anees, 2004) This type of OA occurs as a result of irritation or toxicity. Two subtypes can be distinguished: - Reactive airways dysfunction syndrome (RADS). This is caused by single or multiple exposures to high doses of an irritant. Its onset, however, is linked to a single exposure. It is also known as OA without a latent period, since the symptoms appear within 24 hours of exposure. - OA caused by low doses of irritants. This occurs after repeated contact with low doses of the causative agent. ... It is a condition of particular current relevance but that is still under discussion. 3. Other variants of OA. This category includes OA with special or distinctive characteristics: - Asthma-like disorders. These are due to exposure to plant-derived dust (grain, cotton, and other textile fibers) and also to dust from confined animals. - Potroom asthma. This occurs in workers involved in the production of aluminium. Prevalence and Incidence Notable discrepancies are found in the data on prevalence and incidence currently available in the medical literature. Differences in the design of epidemiologic studies, the definition of OA, the study population, and the country in which the study was performed account for some of the discrepancies and the consequent difficulty in making comparisons. Some of the data can be found in a recent review article. It has been reported that 4% to 58% of all cases of asthma may be occupational in origin. A recent review of the literature estimated a mean value of 15%. Immunologic OA caused by high molecular weight substances is the most common form. (Anees, 2004) The prevalence of the disease varies depending on the causative agent and it has been shown to occur in 4% to 12% of animal laboratory workers, 79% of bakers, and 1% to 7% of health care workers exposed to latex. The prevalence of OA caused by sensitization to low molecular weight substances is less clear, although some authors estimate it at around 40% of all cases of OA. The agents most frequently implicated in the disease in industrialized countries have generally been the isocyanates, which cause asthma in 2% to 10% of workers. (Nicholson, 2002) In British Colombia, Canada, where the wood industry is very extensive, another agent, cedar wood, is more common and is

Mill offers several reasons why experiments of living should be allowed. He offers the infallibility argument, in which he contends that society, as it is, is not perfect and the only manner in which society can move forward is by allowing for experiments of life (Gray 52). Natural selection and the forces that drive it need change to occur if they are to work. The selective process would only allow the production of happiness. Whereby, if there is a greater population of people living happily under a particular method, this method will spread to other areas. Since a specific way of life could be an improvement on the way people live; no way of life should be forbidden or suppressed (Gray 52). In the case of a woman with no child ren refusing medical help for anyone, her life cannot bring any happiness and, as such, cannot spread. This way of life will not improve anyone’s life, including hers. ... Ways of life that are flawed, rendering them undesirable as the common rule, rather than being the exception, do possess merits and valuable ideas. Ideas that can benefit society can only be achieved when society allows practical testing and trial of these ways of life (Gray 54). Therefore, even disagreeable living experiments like that of this woman should be allowed in the case of not bearing children. This partly true argument can be furthered through the contention that even a way of life that has no tangible benefits for anyone involved must be allowed. This is because it will act as a highlight to the benefits of other ways of life (Gray 55). Only when society tries out a way of life in reality that it can be judged to have no merit. Hence, it acts as evidence of the manner in which its guiding principles work practically. For example, the woman who refuses medical care for everyone may be suggestive of life that is permanently full of divine grace and hope, which is a perfect aim to work for. An experiment of living like this one offers vivid evidence that the goal it aims for is flawed. John Mill also argues that the fact that the human race is made of diverse groups and cultures, is proof that society should encourage diverse modes of living. All persons possess different characters and, therefore, all persons have diverse ways of life, which are best for them. In John Mill’s words, â€Å"The same mode of life is a healthy excitement to one, keeping all his faculties of action and enjoyment in their best order, while to another it is a distracting burden which suspends or crushes all internal life† (Mill 44). Where there is an attempt to

One Subject Infographic Assignment Example | Topics and Well Written Essays - 750 words

One Subject Infographic - Assignment Example It is from this controversy and falasy that I decided to do research on marijuana. The study involved both qualitative and quantitative data. The main objective of the study conveyed in my infograph is that marijuana is not dangerous as it is perceived to be by most people. The data was obtained from Columbia University and survey report on National Survey on drug use and health. The data and information was presented using graphs 1 and 2 as shown below. The comparison study against Marijuana was done against group of drugs listed as narcotics, Stimulants, Depresants, Non-alcoholic drugs, Alcohol and Alcohol& other drugs. The first comparison was done to assess how many people aged 12years and above use Marijuana against other drugs like Cocaine, Illicit drugs, psychotherapeutics, hallucinogens, Inhalants, heroine. From graph 1, about 25million (23.9%) people aged 12years and above consume illicit drugs. This was followed by marijuana consumed by about 20million (18.9%). About 6.8% have mental illness disorders (psychotherapeutics) which was related to other drugs taken and not marijuana. From the graph, it can be seen that Marijuana is second preferred drugs after other illicit drugs consumed in USA. The second analysis involved assessing and validating whether the effects marijuana can cause road accidents. Under this category, the drugs were classified in groups as highlighted above to take care of many population and different drugs. From graph 2, most accidents in USA are caused by people who take drugs that fall under the category of Alcohols and other drugs. This is represented by about 23.24%. The second harmful category of drugs is from the alcohol representing about 13.64%. This was followed by multiple non-alcoholic, depressants and stimulants. Most road accidents are least caused by the influence of marijuana, as can be seen in figure 2 this is represented by about 1.83% only. I also wanted to prove further behavior of people on use
