1. Chapter 4: Types, Traits, and Interactionism Theories of Personality January 31, 2003 Class #2

2. Types Carl Jung (1933) –Are you introverted or extroverted??? We are a “type”…either one or the other, distinct and discontinuous Like male and female…can only be one Any appearance to the contrary is just a distortion of one’s basic personality

3. Traits: The Dimensional Approach People differ across dimensions which are continuous People differ in varying amounts Differences among people are quantitative rather than qualitative People vary from one another in varying amounts concerning their personality characteristics – not talking about different aspects just different degrees of the same aspect

4. What traits are basic to personality? Factor analysis –Rates people on a number of items representing different dimensions (in this case, traits) –Looks at the correlations among the items (what traits were high at the same time and what traits were high when others were low) –Creates groups based on this correlations –Used to group a large amount of data

5. Nomothetic View of Traits A trait has the same meaning for everyone Allows for comparisons among people Draw on underlying dimensions identified through factor analysis

6. The Idiographic Approach Belief in the uniqueness of individuals Concerned with the whole person Often employ case-study methods Advocates include: Advocates include: –Allport (1937) –The humanistic psychologists Maslow, Rogers, etc)

7. Gordon Allport (1897-1967) Gordon Allport was born in Indiana As a child he felt different from others, both in his childhood play and his interests After high school he followed his older brother Floyd to Harvard University Floyd made a name for himself in social psychology, but Gordon felt like an outsider in this arena He was not a psychology major

8. Allport’s Background He taught sociology in Turkey, then returned to Harvard to learn how to teach Psychology After receiving his Ph.D., he traveled to Berlin, Hamburg, and Cambridge for additional study, spent 4 years teaching at Dartmouth, and returned to Harvard for the rest of his career He is credited with being the first to teach a course on Personality Psychology

9. Allport’s Background Gordon was interested in personality, and at the time, personality was not a formal sub-discipline of psychology and it certainly was not as fashionable as social psychology He probably followed his brother through school in an attempt to find himself He reported feeling different from others, including his older brother This feeling, however, might have helped him succeed in his chosen profession

10. Gordon Allport In 1920, one year after receiving his bachelor’s degree from Harvard, this curious psychology student met Sigmund Freud for the only time in his life… He set up an appointment to interview Freud, who was 64 years old at the time… –Later, Allport would describe the event as a “traumatic developmental episode in his life”

11. Their meeting… Allport arrives at Freud’s office and is taken back by the complete silence that Freud opens the meeting with… In an attempt to lighten the tension, Allport mentions an incident that had occurred on the train on the way to Freud’s office: –A four year-old boy displayed a pronounced phobia towards dirt –To the boy, everything was dirty…the seat was filthy…“don’t let that dirty man sit next to me”, etc.

12. Plunging too deep??? It clearly appeared to Allport to be caused by the boy’s dominant mother who sat next to him and he related this feeling to Freud… –Freud finally breaks his silence by asking Allport, “and was that little boy, you? From this interview Allport leaves feeling that psychoanalysts might be better off recognizing obvious motives rather than probing the unconscious

13. Disagrees with Freud on a couple of accounts… Allport suggested that normal, mature human beings were not irreversibly driven by the events of childhood Allport presented a positive and hopeful picture of people in conscious control of their own lives Note: –He genuinely liked people and cared about them –By all accounts, these feelings were reciprocated by his students

14. Trait Theory Takes behavior at “face value” –Allport was less concerned with explaining why we differ from one another and more concerned with describing how we differ… So, the big distinction between Freud and Allport is explanation vs. description –Allport wrote that psychologists should give full recognition to manifest motives before delving into the unconscious –Allport was not completely opposed to psychoanalysis, he just felt it would be better to combine his ideas with it…this is important because not all trait theorists agreed with him on this point

15. People are unique… Allport was convinced, along with Freud, that what Freud called "the American approach to psychology" was not only boring, but misleading According to Allport, compiling ranks of statistics, averaged across individuals describes everyone in general and no one in particular It misses the personal meaning of life's events, and the individual ways of responding to life's events that Allport called traits Allport called this statistical approach to understanding human nature the nomothetic method, and contrasted its emptiness and aridity to the richness of the idiographic approach -- an approach centered on the meanings and stories of the individual

16. Trait Theory Trait theorists do what Freud would not…they describe personality in terms of fundamental traits – they look at people’s characteristic behaviors and conscious motives… –Allport is able to do something that Freud for the most part could not… He felt that traits could be measured and studied? Where does Freud get his stuff? –Did he use the scientific method?

17. Trait Theory Allport goes through the dictionary and finds about 18,000 separate words that he feels could be used to describe one’s personality After eliminating synonyms, he is still left with about 4500 descriptors The problem crucial to all trait theories…which of these were the most basic traits???

18. Trait Theory 3 basic categories of traits: –Cardinal trait –Central traits –Secondary traits

19. Trait Theory Cardinal trait –This is the single characteristic trait that directs most of a person’s activities For example, a totally selfless person might direct all their energies toward humanitarian activities

20. Trait Theory Central traits –These are the major characteristics of the individual (5-10 traits) For example, honesty and sociability may be two central traits that make up the core an individuals’s personality

21. Trait Theory Secondary traits –These show up in fewer situations and are less influential than central or cardinal traits For example, a preference for modern art or clothing style or what’s your favorite ice cream is could be secondary traits

22. Situational factors… Allport also recognized that the situation was important but thought that traits were stable over a range of situations –So, his is a strong vote for personality having a stronger influence than the situation on behavior

23. Raymond Cattell (1905-1998) Born in England His father was a mechanical engineer and craftsman-designer who worked on such projects as developing World War I military equipment, the steam engine, and a new internal combustion engine His mother and father both extremely intelligent with IQ’s of 150 and 120 respectively

24. Cattell’s Background Cattell describes a happy childhood and youth both at home and at school, which upon comparison with other behavior and personality theorists is an unusual situation Cattell distinguished himself in high school and earned a county scholarship to attend London University where he majored in chemistry After a period of soul-searching, he concluded that work in the new social science of psychology would be most relevant in solving the outstanding political and economic problems that he saw around him He felt that traditional solutions were not working and that developing an understanding of human nature was necessary to find new solutions

25. Cattell’s Background After working in various applied settings, in 1937, he accepted an invitation to join E.L. Thorndike's research staff at Columbia University He taught briefly at Clark University and then at the invitation of Gordon Allport, Cattell joined the Harvard University faculty in 1941 In 1945, he took a faculty position at the Univ. of Illinois where he retired in 1973

26. Cattell’s Approach Used a Lexical Approach –Presumably the importance of a trait is related to the number of words used to describe it (???) –Cattell took 4500 trait words (already reduced by Allport) and removed obvious synonyms and then factor analyzed them

27. Cattell’s Approach His definition of personality: –That which a predicts what a person will do at a certain situation Started the actual measurement of personality Developed 16 PF –The 16 factors are NOT orthogonal Orthogonal: a unique category (factor) by itself Oblique orthogonal: related with other factors

28. Cattell’s Approach Measured many different aspects of personality Identified 16 “source traits” or basic dimensions of personality Based on this model of personality, he created “16PF” (see page 64) He used self-reports, observer ratings, and objective tests to help determine a person’s traits Used statistics, formulas, probabilities, etc. He called this his multivariate approach

29. Cattell’s Approach Analyzed the following traits: –Manifest (overt) = surface factors –Latent (covert) = source factors –Constitutional traits (biological) –Environmental molded traits (social cultural)

30. Ergs Cattell felt that labels were highly subjective and easily misinterpreted so he invented many words… –“Ergs” Anger, curiosity, fear, greed, hunger, sex, etc. Each erg is associated with a particular goal He felt that the levels of ergs differ from person to person due to genetics

31. Hans Eysenck (1916-1997) Hans Eysenck was born in Germany on March 4, 1916 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

32. Eysenck He 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 Later, he taught at the University of London He has written 75 books and some 700 articles, making him one of the most prolific writers in psychology Eysenck retired in 1983

33. Hans Eysenck Eysenck regards personality as being primarily an inborn phenomenon-- that means that personality, to him, is more like eye color or height than it is like learned phenomena He proposed that we have two super traits which operated on a type of continuum… –Unstable (neurotic) vs. stable –Extraverted vs. introverted He used factor analysis to determine these dimensions

34. Super Traits 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 “nervous” 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 “nervous” His research showed that nervous people tended to suffer more frequently from a variety of “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

35. Super Traits The extraversion dimension concerns tendencies towards sociability, craving excitement, liveliness, activeness, and dominance –The emotional stability dimension concerns the ease and frequency with which the person becomes upset and distressed –Greater moodiness, anxiety, and depression reflect greater emotional instability

36. Extraversion-introversion Shy, quiet people “versus” out-going, even loud people. This dimension, too, is found in everyone, but the physiological explanation is a bit more complex… –Introverts were over-aroused individuals therefore they try to keep stimulation to a minimum –Extroverts were under-aroused individuals, therefore they tried to increase stimulation –He felt that personality was partly due to genetic factors

37. A Point for Nature… Note: –Notice how the study of personality reflects the nature-nurture problem… Eysenck's theory leans toward the nature end of the continuum It is based primarily on physiology and genetics He considers personality differences as growing out of our genetic inheritance He is primarily interested in a person’s temperament

38. The Big Five Several researchers have found evidence for the existence of five basic dimensions of personality through factor analysis 5 factors are independent of one another Everyone can be placed along a continuum for all 5 factors/traits

39. The Big Five ExtraversionAgreeablenessConscientiousness Emotionality (also referred to as Neuroticism) Intellect (also referred to as Openness)

40. What researchers say… From a review of literature the following are some of the important characteristics of the five factors: –The factors are dimensions, not types, so people vary continuously on them, with most people falling in between the extremes –The factors are stable over a 45-year period beginning in young adulthood –The factors and their specific facets appear heritable –The factors are considered universal –Knowing one's placement on the factors is useful for insight and improvement through therapy

41. What Are These Five Factors? Extraversion Extraversion –Bold versus timid –Outgoing versus introverted –Talkative versus silent Agreeableness Agreeableness –Friendliness versus indifference to others –A docile versus hostile nature –Compliance versus hostile noncompliance Conscientiousness Conscientiousness –Responsible versus irresponsible –Hardworking versus lazy –Cautious versus rash

42. What Are These Five Factors? Neuroticism Neuroticism –Adjustment versus anxiety –Level of Emotional stability –Dependence vs. independence Openness Openness –Reflection of an inquiring intellect –Flexibility versus conformity –Rebelliousness versus Subduedness

43. Okay, is behavior really trait-like? Are traits stable across a wide range of settings? Walter Mischel says no –See next slide

44. Mischel (1968) A long-time personologist attacked trait theory Disputed the “generalized and enduring causal effects on behavior” Coined the phrase “personality coefficient” to characterize the modest correlations between trait self-reports and behavior which he said typically were between.20 and.30 Note: Mischel’s biography and more in-depth coverage of his theories will be covered near the end of the semester (Chapter 16 – Contemporary Cognitive Views)

45. Mischel (1968) For example, the consistency between children's honesty in one social situation (e.g., one's willingness to steal some change left on the table of an empty classroom) and their honesty in a different social situation (e.g., willingness to cheat during an exam) amounted to a correlation of.20

46. Situationism: The person vs. the situation debate rages on… Data of this sort, pointing to the low cross- situational consistency of personality traits, constitute a strong situationist challenge to the power of person factors in accounting for human behavior

47. Personality psychologists on the defensive… Many personality psychologists were disturbed by these challenges, and some were even enraged because they felt it was an invalid attack against a whole discipline The social psych camp went on an attack mode originated in the “heresy” committed by former personologist Mischel

48. The rebuttal… Personality psychologists claimed that Social psychologists can easily create situations in which personality influences are minimized –Doesn’t give a true picture of what happens in the real world The personality dispositions that a person values very highly or those that are integral to his or her goals in life will influence his or her behavior more markedly than other dispositions –The situation won’t affect behavior if its dealing with an important disposition

49. Mischel’s idea led to interactionism… Its not the person or the situation but rather the person and the situation…??? They interact to produce the behavior…??? Variations in situations affect some people in one way and affect others in a different way –For example, last week’s video camera may have caused the extroverts in this class to want to give longer introductions whereas the introverts may have wanted to dig a hole and hide

50. Lets go a little deeper… What is a situation? Do situations change people? Or do people change or even make a situation? –Hastorf and Cantril (1954)

51. Hastorf and Cantril (1954) Princeton vs. Dartmouth football game –Very rough game – a Dartmouth player was taken off on stretcher with broken leg and a Princeton player broke his nose – many penalties throughout the game –A week later undergraduates were shown a film of the game and described it in two very different ways –Princeton students “saw” the Dartmouth team make twice as many penalties as the Princeton students “saw” them make

52. Hastorf and Cantril (1954) The researchers said there is “no such thing as a game existing out there in its own right” The person sees the game he or she wants to see So, does the person makes the game? –How about in real life?

53. How do you respond to sales calls? Are you making the situation here?

54. Interactionism in Behavior Problems Diathesis-stress model –A person has a predisposition to develop an illness but it may remain dormant unless triggered by something (stressors) Social causation is an example of this Living in a poor environment might lead the vulnerable person into deep depression

55. Psychology of a stranger??? Criticisms of Trait Theories –Tells us only things someone might want to know if they knew nothing else about a person Labels them…but that’s about it –Circular explanations Not really explaining why –A person’s behavior may not be stable across situations Very debatable criticism

56. Final words… Are we strong or are we weak? –Well, this was a start in our search to determine if its personality that matters most –We’ll be addressing this the rest of the semester
