Personality Lectures ch 12 Flashcards
Personality
is a person’s unique and relatively stable pattern of thinking, emotions and behaviour.
Personality traits
are differences among individuals in their thoughts, feelings and behaviour that are stable over a variety of situations and a fairly long period of time.
Discuss evidence showing that personality traits are indeed stable over a fairly long period of time.
Did a study where individuals were asked personality-related questions, and were assessed again 4-10 years later; found evidence of stability
Conversely, is there any evidence that personality can change?
Review papers of clinical interventions, like therapy; saw evidence of personality changing as a function of those interventions
Personality traits have also been described as automatic tendencies. What does this mean?
- Personality is how you naturally or automatically respond to in situations: do you get upset/mad/sad easily?
What are some psychological concepts that would not be considered personality traits?
- Beliefs and values
A lexical approach
is the first step used to find a small set of personality traits that can provide a complete description of the key aspects of our personalities. Lexical means relating to the words or vocabulary of a language
Using a lexical approach, how do researchers identify and study words, that people use to describe their personalities?
- Identify common personality descriptive adjectives in language
- Ppts rate how well they are described by the adjectives
Factor Analysis
is a statistical technique that places specific personality traits into a small number of general categories, depending on how the traits correlate with one another.
Source traits/personality factors
Basic, underlying traits
Surface traits
Specific traits
Hans Eysenck used factor analysis to develop a personality theory with two basic, underlying personality traits. Describe the two basic, underlying traits and the specific traits that make up these personality traits.
- Extraversion vs. introversion
- Emotional stability vs. instability
Big-5 and HEXACO models of personality, as shown in the Figure below. What traits do these two models have in common, and what is he major difference between them?
- Big five: 5 factor model
- Hexaco: six factor model
- Both have 5 personality traits in common: openness to experience, emotionality/neuroticism, extraversion, agreeableness, conscientiousness
Personality Inventories
Personality traits and factors are measured using personality inventories
- Standardized questionnaires: Ask the questions in the same way for all respondents
- Likert scales: Given several ratings that are then summed up for each question/item that pertains to a personality trait
- Self-report or other-report inventories: Either you or someone who knows you well rates your personality
MMPI-2 : Minnesota Multiphasic Personality Inventory 2nd edition
is used to measure problematic personality traits that are relevant to clinical psychology and psychiatry, on 10 clinical scales.
details about the 10 clinical scales.
- Hypochondriasis (HI-po-kon-DRY-uh-sis). Exaggerated
concern about one’s physical health - Depression. Feelings of worthlessness, hopelessness, and
pessimism - Hysteria. The presence of physical complaints for which
no physical basis can be established - Psychopathic Deviate. Emotional shallowness in
relationships and a disregard for social and moral standards - Masculinity/Femininity. One’s degree of traditional
“masculine” aggressiveness or “feminine” sensitivity - Paranoia. Extreme suspiciousness and feelings of
persecution - Psychasthenia (sike-as-THEE-nee-ah). The presence
of obsessive worries, irrational fears (phobias), and
compulsive (ritualistic) actions - Schizophrenia. Emotional withdrawal and unusual or
bizarre thinking and actions - Hypomania. Emotional excitability, manic moods or
behaviour, and excessive activity - Social Introversion. One’s tendency to be socially
withdrawn
Describe how a pool of possible items for the MMPI-2 were selected for clinical content
- Items are selected for clinical content from clinical sources
Explain how an empirical strategy, rather than factor analysis, was used to select the specific items on each clinical scale
- Looked at which of the of the items best differentiate people with a high level of a particular clinical trait vs a low level
explain how statistics can be used to make clinical decisions on personality inventories like the MMPI-2.
Norms : The distribution of scores obtained by a normative group, a large demographically representative group of individuals who previously completed the personality inventory
Clinical cutoff score : The threshold on personality inventories that divides scores in the normal range from those that are exceptionally high compared to the scores obtained by the normative group
Clinically significant scores : Score above cutoff; only 6%
Personality Disorders
- an enduring pattern of emotions, thoughts, behaviour, and interpersonal functioning that deviates from cultural norms and expectations, and causes clinically significant distress or impairment in social, occupational or other important areas of functioning
Personality Traits
- Differences among individuals in their thoughts, feelings and behaviour that are stable over a variety of situations and a fairly long period of time
Which part of the definition of personality disorders distinguishes them from personality traits? Explain why this is so.
“that deviates from cultural norms and expectations, and causes clinically significant distress or impairment in social, occupational or other important areas of functioning
Personality traits do not impair functioning, or deviate from norms
How are personality disorders assessed differently than traits on personality inventories that reflect personality problems (e.g., Paranoia on MMPI-2)?
- Personality disorder diagnosis is not based on filling out a questionnaire; instead, use DSM-5 (basing diagnosis on the symptoms described)
There are 10 different personality disorders in three clusters
A. Odd or eccentric behaviour
B. Dramatic, erratic, emotional behaviour
C. Anxious or fearful behaviour
give examples of personality disorders in each cluster.
A Paranoid PD Deeply distrusting and being suspicious of others, perceiving their motives as insulting or threatening
B Borderline PD extreme sensitivity to the possibility of criticism, rejection or abandonment; unstable relationships, moods and self-image
C Obsessive compulsive PD preoccupation with orderliness, perfectionism, and control, at the expense of flexibility and efficiency, so they are rigid and stubborn.
Which personality traits predict the real-life outcomes in the table below?
Compatibility with romantic partner: Small positive correlation between spouses personality traits
Relationship satisfaction: Greater marital satisfaction when spouse is low in emotionality, and high in agreeableness and conscientiousness
Overall job performance: High conscientiousness
Happiness and well-being : High extraversion
Longevity : High conscientiousness
How do the links between personality traits and relevant behaviours support the validity of personality models like the HEXACO?
- Items used to define personality traits actually predict theoretically relevant behaviours
Define validity
Does an item actually measure what its supposed to?
Describe twin study evidence that shows genes influence the development of personality traits.
- Average correlation of twins personality traits
- Identical / MZ twins: r=.54
- Fraternal / DZ twins: r = .27
Natural selection:
traits that helped our ancestors to survive and reproduce would be more likely to be passed to later generations through inherited genes.
adaptive trade-offs
so that there is no such thing as personality trait that is all good or bad
Honesty-Humility; Agreeablenes: Cooperation: Vulnerable to exploitation
Emotionality/Neuroticism: Survival of self and kin: Loss of potential gains due to avoiding risks
Extroversion; Conscientiousness : Social and material gains : Takes time and energy
psychoanalytic
psychoanalytic view is that personality is shaped by unconscious forces
