    • Describe the “Big 5” theory of personality traits


Psychology 100 12

Psychodynamics

The mind is a battlefield for the warring factions of instinct, reason, & conscience

  • Sigmund Freud (1856 - 1939).

    • Obtained M.D.

      • Early training in Neurology with von Brück.

      • Dissection and observation

    • Unable to gain a position in a University.

      • Studied with Charcot in Paris.

      • Hypnotism

    • Opened up medical practice in Vienna.

Psychodynamics

Freud’s Topography

  • The unconscious

    • Instincts, wishes, and impulses.

    • Many are socially unacceptable

  • Consciousness is the “tip of the iceberg”

  • Categories of instincts

    • Eros: The life force.

    • Thanatos: The death force.

  • Tension reduction principle.

    • Maintain psychic equilibrium


Psychology 100 12

Psychodynamics

  • The preconscious and conscious

    • Libido: The primary source of motivation, which comes from the unconscious.

      • “Psychic Energy”.

      • Eros & Thanatos give rise to tension.

      • Reduce tension by attaching libido to objects (Carthexis).

        E.g., You are hungry

        • Apply psychic energy to obtaining food (form a carthexis).

        • Tension is reduced.

  • The preconscious: Emotions, thoughts, and feelings that can be called up into consciousness.

  • The problem of limited libido

    • Struggle for limited resources involves the conscious as well as the unconscious

      • We need to operate on the external world


Psychology 100 12

Psychodynamics

Id:Unorganized, uninhibited, and irrational set of instincts.

  • Entirely unconscious

    Ego:Rational, mostly conscious aspect of a person

  • Partly pre and unconscious

    Superego:Societal prescriptions for appropriate behaviour

  • Partly conscious, pre and unconscious

  • From our parents


Psychology 100 12

Psychodynamics

  • Psychosexual Development

    • The pleasure principle: Rule of the id: Gratify me!

      • Main drives: Hunger and sex

      • Development of digestive and sex organs are critical in the development of adult personality

        • Erogenous zones: instinctual sources of pleasure

    • Stage approach to psychosexual development

      • Each stage is linked to an erogenous zone

      • Conflicts occur over control of instincts at each stage

      • Excessive gratification or frustration results in fixation


Psychology 100 12

Psychodynamics

  • The oral stage (0-2 yrs)

    • Too much or too little attention -> oral fixation

      • Overgratification: Optimistic, gullible, and admiring

      • Undergratification: Pessimistic, suspicious, and envious


Psychology 100 12

Psychodynamics

  • The anal stage (> 2 yrs)

    • Ego development

    • Conflict over the parent’s attempt to control when gratification can occur.

      • Strict training (Anal retentive): Obstinate, stingy, orderly, meticulous

      • Undergratification (Anal expulsive): Acquiescent, generous, messy


Psychology 100 12

Psychodynamics

  • The Phallic stage (3-5 yrs)

    • Superego development

    • The Oedipus Complex (boys)

      • Castration anxiety

      • Identification with the morals of the father reduces the anxiety

    • The Electra Complex (girls)

      • Believes mother is responsible for her castration

      • Develops penis envy. Wants to have a child by her father to indirectly acquire a penis.

      • Identifies with mother to gain vicarious satisfaction


Psychology 100 12

Psychodynamics

  • The latency period (5 - 11)

    • A respite from conflict

  • The genital stage (Puberty)

    • Becomes an adult

      • No longer polymorpheus perverts

      • Some fine tuning of Ego

      • Can obtain gratification from others

  • Adulthood

    • Personality is riddled with unconscious conflicts

      • Leads to a rise in anxiety

      • Ego must defend the conscious mind from unconscious impulses


Psychology 100 12

Psychodynamics

  • Defense mechanisms:controlling unconscious thoughts.

    • Repression: Bury them deep in the unconscious

    • Reaction formation: Replace a threatening idea with the opposite.

      • E.g, Homophobia

    • Projection:Deny your own desires, and perceive others as presenting them.

      • “I’M NOT THE ONE WHO’S ANGRY!!!!!”

    • Sublimation: Divert energy into something acceptable.

      • Sexual energy --> creative energy

    • Rationalization: Invent a reason for unacceptable behaviour

      • E.g.,only buying the magazines for the interviews…


Psychology 100 12

Personality

  • Personality assessment

    • Objective tests of personality

      • Minnesota Multiphasic Personality Inventory (MMPI)

        • Construction

          • Taken from previously published “inventories”

        • Scale items

          • Statistically reduced to 566 items; 10 scales

          • E.g, Depression, paranoia, introversion, etc.

  • Objective tests of personality

    • Validity scales

      • The ? scale - Number of questions not answered

      • The L scale - Catch lies

      • The F scale - Frequency (90%)

      • The K scale - Defensiveness.

    • Predictive Validity

      • Criterion validity: r = .3

      • Less than other measures like past behaviour

        Aggressive -------------------> Angry

        Emotionally Unstable -------------------> Infactuated


Personality7

Personality

Personality

  • Trait theory on limited dimensions.

    • Allport (1936)

      • Started with 18,000 descriptive words

        • Cardinal traits: Rare, strong unifying effect.

        • Central traits: Less singular, capture important characteristics.

        • Secondary traits: Minor influences on behaviour.


Psychology 100 12

Personality

  • Trait theory

    • Cattell’s theory

      • Used Allport’s list as a starting point, reduced to 171

        • Reduced the list further and had 200 others rated

        • Performed Factor Analysis:

          • E.g., Aggression, stubborn, leadership

            Dominant ----- Submissive

        • Developed 16 source traits

        • Developed the 16 PFQ

          • 200 questions

            I like to go to parties

            Yes ..... Occasionally .......No

Personality

Personality

  • Trait theory

    • Eysenck’s three factor theory

      • Collected large amount of data -> accounted for it with 3 factors

        • Introversion - Extroversion

          • (introspective vs. gregarious)

        • Neuroticism - Stability

          • (anxiousness, excitability vs. calmness)

        • Psychotocism - Self-control

Personality

Personality

  • Brain mechanisms in Personality: Zuckerman

    • Extroversion -> High sensitivity to reinforcement

      • Infants with high activity levels ---> Extroverts

      • Extroverts show reinforcement seeking behaviour

        • Introverts have higher internal arousal levels

        • Extroverts have lower internal arousal levels

    • Neuroticism -> High sensitivity to punishment

      • Oversensitive amygdala

    • Psychopathy -> Low sensitivity to punishment

      • Cannot learn when NOT to do something

        • High tolerance (set point) for arousal and excitement


Personality12

Personality

Personality

  • Situationism

    • Consistency

      • Mischel’s View: Traits are situation specific

        • Low consistency across situations

        • Honesty scale and cheating behavior: r = .20-.30

      • Interactionism

        • Behaviour is a product of disposition, situation, and the interaction between disposition and situation

Personality

  • Heritability of personality traits

    • Twin studies (Compiled by Zuckerman (1991)

      • Heritability

        • Extroversion -> 70 %

        • Psychotocism-> 59 %

        • Neuroticism -> 50%

      • What about the rest of the variability?

        • Reared together/apart -> No difference

        • Adopted /Parents: 4-7% of variability

          50 + 7 = 57%

      • Where does the rest of the variability come from?

        • The interaction between nature and nurture


Personality15

Personality

Personality

  • Three levels of personality(McAdams)

    • Dispositional traits

      • Internal, global, and stable (e.g., friendliness)

    • Characteristic adaptation

      • Personal adaptation to motivational, cognitive, developmental challenges

    • In ‘life stories’ people say their personality changes

      • Narratives of the self to integrate the past, resent and future.
