Sources of Personality Data
Self-report data (S-data): information a person reveals
oNot always accurate
oMost common
Self Report Data
Interviews, periodic reports, questionnaires (most common)
Open-ended, to force choice true or false
Open ended: the Twenty Test (I am…)
Adjective Check List (ACL)
Likert rating scale: way to express in numbers the degree to which a trait describes them (1-------7)
Personality scale: summing the scores of individual rating scales
NEO Personality Inventory
California Psychological Inventory (CPI)
Must be truthful in self report
Observer-Report Data (O-Data)
O-data: impressions and evaluations others make of people they come in contact with
oMore valuable with multiple observers
Inter-rater reliability: use multiple observers and an investigator to evaluate the degree of agreeableness
among observers
Selection of Observers
Two ways
oUse professional personality assessors who do not know the person
oUse people who know the person
Multiple social personalities: examine personalities in different settings and situations or
with different people
Naturalistic vs. Artificial Observation
Naturalistic observation: observers witness and record events that occur naturally
Artificial: in a lab setting
Test Data (T-Data)
Test data: standardized tests
oTo see if different people react differently to the same situation
oMegargee (1969) study on manifestations of dominance
It is possible to set up conditions to reveal key indicators of personality
Lab experiments should be sensitive to manifestations of personality that occur in
incidental parts of the experiment (discussion among participants)
