Task 3 - Assessing Personality Flashcards
Personality traits
Differences among individuals in a typical tendency to behave, think, or feel in some conceptually related ways, across a variety of relevant situations and across some fairly long period of time
Structured personality inventories
Individuals given predetermined set of options for responding to items of test
Negative keying/reverse coding
Many items suggest opposite of trait in question
- > greater disagreement: higher scores on opposite trait
- > reason: some people respond in direction of greater disagreement
- > usually 50/50 with positive keying
Strategies of Personality Inventory Construction
- Empirical strategy
- factor-analytic strategy
- rational strategy
Empirical strategy
Writing down large number of items describing variety of actions, thoughts, and feelings and items asking for ratings on characteristics
- > items selected on basis of observed evidence of relations of items with other information believed to be related to characteristic
e. g. GPA for achievement
Factor-analytic strategy
Starts with large and diverse pool of items
-> items are grouped, each group measuring a different trait
Rational Strategy
Items written specifically for purpose of traits being measured
- > you produce items that you rationally deem to be related to a trait
- > show best validity and reliability
Big Five inventory
Short measure of Big Five (OCEAN)
- contains 44 items
- high levels of internal-consistency reliability and content validity
NEO-PI-R
Developed to measure 5 major dimensions of personality
- 240 items grouped into 30 scales
- measures narrower traits than Big Five
- good levels of reliability and validity
- most widely used in psychological research
Self-serving bias
Putting yourself in a good light (or bad light) on purpose in assessment
Observer bias
Bias in observer report trying to make the subject appear in certain way
Projective Tests
Tests with unstructured responses
- allow individuals to respond in own fashion
- e.g. Rohrschach test, Thematic association test
- > validity often questioned
Factor analysis
Categorizing variables into groups according to correlations between them
- factors are separate and independent from each other
- factor loadings: between -1 and 1
Lexical approach
Full list of personality-descriptive adjectives in a language is considered to administer a complete list of relevant personality traits
Extraversion
includes: talkativeness, liveliness, outgoingness vs shyness, quietness, and passivity
