Flashcards in TASK 3 - PERSONALITY INVENTORIES Deck (33)
1

personality trait

= (1) differences among individuals (2) in a typical tendency to behave, think, or feel (3) in some conceptually related ways, (4) across a variety of relevant situations and (5) across some fairly long period of time

2

Differences among individuals (1)

= personality trait relative to degree of other people

3

In a typical tendency to behave, think or feel (2)

= likelihood of showing behaviours, thought or feelings
- strong/weak inclination to exhibit behaviours --> external (actions, words) + internal (ideas, emotions)

4

In some conceptually related ways (3)

= trait is expressed by various behaviours, thoughts, feelings that have some common psychological element

5

Across a variety of relevant situations (4)

= shown across variety of settings --> not simply habit to specific situation

6

Over some fairly long period of time (5)

= stable tendency to show relevant pattern of behaviours
- tendency can change across entire life span (long-lasting approximately over a few years)

7

structured vs. unstructured personality inventories

structured = predetermined set of options, each related to specific 'trait'
- reverse-coded items
√ good reliability: average response, good indicator of element that is common to items
√ good content validity: items describe wide array of interests, all of which are related to element being measured

unstructured = use of unstructured responses, leaves room for interpretation
x interpretation of practitioner

8

projective hypothesis

= respondents project aspects of their personality onto unstructured test stimuli
- projection = defence mechanism is described by individuals attributing own (unwanted) personality traits to others (Freud)

9

projective techniques

= present respondents with an ambiguous stimulus, ask them to disambiguate/decipher/interpret the stimulus

10

rorschach inkblot test

= series of inkblot patterns; for each inkblot individual asked to interpret what is seeing in pattern
- inkblots: designed to look like one thing in one part and something contradictory in another part; some suggestive shapes that many people can see, personal perception puts 'critical bits' together
x many psychologically normal people appear to be pathological --> inaccuracy with norms
- impracticability of administering and scoring test

11

thematic appreciation test (TAT)

= picture of some people interacting/paragraph that describes beginning of a story; individual is asked to tell a story about the picture/complete story
- pictures: show person’s view of others, attitudes towards self, expectations about relationships; less abstract stimuli than Rorschach
x difficult to know extent adds predictive validity
x time and labour-intensive, no large samples possible

12

strategies for structured inventories

- empirical strategy
- factor-analytical strategy
- rational strategy
--> most in rational strategy, often combination

13

empirical strategy

1. writing large number of items that describe very wide variety of actions, thoughts, feelings
- true/false, yes/no, multipoint scale (agreement/disagreement)
2. self-reports (or observer) on large pool of items from large sample
3. extra information for deciding which items should be kept for assessing traits of interest --> items’ relations with outside variable (indicator of given trait)
- empirical selection: on basis of observed evidence of relations of those items with some other information that is believed to give accurate indication of level of given trait (GPA for achievement orientation)

14

advantages/disadvantages empirical strategy

√ no concern about content of item --> solely based on observed empirical links between items and variable
√ difficult to adjust responses in desired way, to fake responses
x variety of item sets possible due to different samples, chosen indicator variable
- select items based on empirical relations observed within several different samples + different variables

15

factor-analytic strategy

1. large and diverse pool of items + large sample
3. find group of related items; each group measures different trait
4. sorting correlated from uncorrelated items:
- correlated items: measure same broad personality trait (= same factor)
- uncorrelated items = different factors
- each factor regards one broad trait

16

advantages/disadvantages of factor-analytical strategy

√ no specific plan of which traits should be measured
- measure major traits that are assessed by item pool
x limited set of traits if item pool is not variable/diverse
x no guarantee that traits will be ideal traits

17

factor analysis

= statistical technique; systematic approach to decide which personality traits to measure
1. many variables show correlations with each other
2. categorising into groups according to correlations
- reduce many variables into few unrelated groups of related variables (few basic groups) --> measure small items of traits
- summarise relations among large number of variables
- factor loadings: range between -1 and +1; indicate which variables belong to which factor
- factors = dimensions along which people differ

18

rational strategy

1. write items specifically for purpose trait aimed to measured
- rationally = rationally relevant items; reveal high level of trait and represent various aspects of trait
2. decide best items to keep for final scale --> asking experts; administer to large sample
- select items with strongest correlations with entire set
3. consider breadth

19

advantages/disadvantages of rational strategy

√ easier to implement, no need for item pool
x resulting scales only as good as sets of items written by psychologist
x easy to figure out intent of inventory, to fake answers

20

lexical hypothesis

= people will want to talk about the personality traits they view as important; invent words to describe people's trait levels
- important descriptive words become established in every language

21

lexical approach

= use existing list of personality-descriptive adjectives in dictionaries of any language
- obtain reasonably complete list of important personality traits
1. search systematically throughout dictionary
2. identify every word used to describe normal personality variation
- exclude rare terms
4. administer list to large voluntary sample
5. factor analysis

22

historical discovery of Big Five/early use of lexical approach

1. Allport and Odbert (1936)
- 4500 personality traits
2. Cattell (1947)
- put synonyms and antonyms together = 35 variables + 12 factors
3. Tupes and Christal (1960s)
- Big Five

23

Big Five

- dimensions
1. extraversion
2. agreeableness
3. conscientiousness
4. neuroticism (vs. emotional stability)
5. imagination/intellect

24

1. EXTRAVERSION

LOW = introverts; shyness, quietness, introversion, withdrawn
HIGH = extraverts; engage in social interactions (social attention), often great impact on social environment (leadership); talkativeness, liveliness, sociable, outgoing

25

2. AGREEABLENESS

LOW = resolve conflicts by being aggressive; cold, rudeness, harshness
HIGH = favour negotiation to resolve conflicts; get along with others; kindness, sympathetic, gentleness, cooperative

26

3. CONSCIENTIOUSNESS

LOW = perform more poorly at school and work (procrastinate); sloppiness, laziness, unreliable
HIGH = hard-working, punctual, reliable; organised, systematic, efficient, discipline
- outcomes: higher GPA, greater job satisfaction

27

4. NEUROTICISM

LOW = emotionally stable; relaxed, easy-going
HIGH = emotionally unstable; great variability of moods over time; moody, possessive, anxious

28

5. OPENNESS TO EXPERIENCE

= imagination/intellect
LOW = more tunnel vision (ignore stimuli); conventional, shallow, unintelligent
HIGH = enjoy new experiences; intellectual, creative, innovative

29

five-factor model

1. neuroticism
2. agreeableness
3. extraversion
4. conscientiousness
5. openness to experience
- downplays importance of intellect MORE willingness to examine new ideas

30

NEO-PI-R

= personality inventory based on five-factor model

31

why development of HEXACO?

- five-factor model not universal --> showed 6th factor
- changes in emotionality (former neuroticism), agreeableness, honesty-humility

32

HEXACO-PI-R

H: honesty-Humility
E: emotionality/neuroticism
X: extraversion
A: agreeableness
C: conscientiousness
O: openness to experience
- for each factor five/seven levels
√ assessment of many different personality types
√ more thorough summary

33

history of personality assessment

19th century
1. phrenology (Gall)
2. Galton: eugenics, first scientific approach; questionnaires to evaluate personality characteristics
20th century
3. MMPI = Minnesota Multiphasic Personality Inventory: military services to select personnel for positions
4. Cattell
5. CPI = California psychological inventory
6. NEO-PI-R
