Types of personality data
S Data
L Data
I Data
B Data
S Data
self-report data
L Data
Life data, bio data (physiological stuff)
I Data
Informant report data, experimenter not there (e.g. friend, relative)
B Data
Behavior data, natural or lab setting
-> direct observation by experimenter
Self-Reports
Askin series of questions about own actions, thoughts, and feelings in various situations
Observer Reports
Asking someone about behaviors, thoughts and feelings of another person (has to know the person)
-> might be more objective than self-report
Direct observations
Observing a person’s behavior directly
Biodata/Life data
Obtaining records on a pereson’s life possibly relevant to personality
e. .g phone bill, GPA
- > objective indicators, though validity unclear
Interrater reliabiltiy
overlap of judgment between observers observing the same people at the same time
Convergent validity
Overlap between different information of observers
-> e.g. observe person at different times/circumstances)
Divergent validity
Testing different things should not be related
-> constructs must be uncorrelated with theoretically correlated measures
Self-report share
98% of trait studies use self-report measures,
only measure in 70%
-> quick, cheap, easy to administer
-> but response bias
Informant Reports Pros & Cons
+: reliability increased since different individuals report, less bias since not talking about yourself
-: needs more resources
Behavioral Measures Pros & Cons
+: possible in lab and natural setting, objective
-: link between behavior and personality trait may not be direct
Multiple Method Approaches
Using mixture of multiple method to get most accurate personality assessment
-> improves construct validity
Self-Knowledge of Personality
Accuracy of self-perception about how one typically thinks, feels, and behaves
Meta-accuracy
Correspondence between people’s beliefs about the impressions they make (meta-perception) and others’ actual impressions
-> slightly more valid than own beliefs about oneself
Accuracy of people’s self-knowledge
People have moderately accurate self-perceptions: do not lack any self-knowledge entirely, but also not totally accurate
Generalized meta-accuracy
People’s awareness of their reputation
Dyadic meta-accuracy
People’s awareness of the impressions they make on specific individuals
-> requires greater social acuity
Interactionist view
Assumes that people interact with their environment to make it suit them
-> e.g. some personality trait levels can be reasonably accurately inferred from own room (e.g. conscientiousness, openess)
Electronically Active Recorder)
Records small audio snippet in certain time intervals
-> allows objective and unobtrusive insight into behavior
-> subtle signs can be recorded,
unobtrusive health indicators can be recorded
-> recordings can be reused (e.g. different experimenter)
