Naturalistic observation
Research method of watching behavior in real-world settings, without manipulating the situation. High in external validity, low in internal validity.
External validity
The extent to which we can generalize findings to real-world settings.
Internal validity
The extent to which we can draw cause-and-effect inferences (reasons).
Case study
Research method of examining one person or one small group of subjects, often for a long period of time. Helpful in providing existence proofs and for generating hypotheses.
Existence proof
“Demonstration that a given psychological phenomenon can occur.” Essentially, just one clear example.
plural of anecdote

Self-report measures
Questionnaires, surveys,
Random selection
Procedure that makes sure every subject in population has equal chance of participating.
Reliability
consistent measurement
Test-retest reliability
yield similar scores over time
Interrater reliability

f
response sets
Tendencies to distort someone’s self-reported answer, often so that it makes them look good
Halo effect
