Document Summary
Hindsight bias the tendency for people to exaggerate how much they could have predicted the outcome after knowing it occurred. Results may appear to have been predictable in retrospect. Three methods used in social psychology: observational method, correlational method, experimental method. Theory an organized set of principles that can be used to explain observed phenomena. Hypothesis a testable statement or idea about the relationship between two or more variables. Diffusion of responsibility people are more likely to help when each person thinks he or she is alone in witnessing the act. Operational definition the precise specification of how variables are measured or manipulated. The observational method technique whereby a researcher observes people and systematically records measurements of their behavior. Varies according to the degree to which the observer actively participates in the scene: observer neither participates nor intervenes in any way; is unobtrusive and tries to blend in with the scenery as much as possible.
