Chapter 2- Methodology: How Social Psychologists Do Research Flashcards
hindsight bias
-people exaggerate how much they could have predicted an outcome after knowing that it occurred
diffusion of responsibility
-assuming someone else will take action
Ex: assuming someone else will call police on disruptive neighbor
methods for answering questions about social behavior
- ) observational method
- ) correlational method
- ) experimental method
observational method
- researcher observes people and records behavior
- goal is to describe what people or type of behavior are like
- ethnography or archival analysis
ethnography
- observing from inside w/o having preconceived notion of subjects
- goal is to understand complexity of group by seeing in action
- must try to understand point of view of people being studied
interjudge reliability
- level of agreement between two or more people who independently observe group
- ensures subjectivity
archival analysis
- researcher examines documents of culture
- diaries, novels, newspaper, etc
- tells about values and beliefs
limits to observational method
- certain behaviors are difficult to observe b.c they rarely occur or occur in private
- typically only one setting, group, etc
- social psychologists want to do more explaining
- archival analysis limited
correlational method
- two variables measured and relationship assessed
- often used in surveys
correlation coefficient
-tells how well you can predict one variable from another
positive correlation
-increased value of one variable is associated with increased value of other
negative correlation
-increased value of one variable associated with decreased value of other
advantages of surveys
- allow researcher to judge relationship between variables difficult to observe
- random selection
random selection
-ensuring sample of people represents population by giving everyone equal chance of being selected
problem with survey
-accuracy of responses
Ex: people may answer how they “should” as opposed to how they “would” in hypothetical situation
correlation DOES NOT
equal causation
experimental method
- only way to determine causal relationship
- randomly assign participants to different conditions
- must have internal validity
- direct intervention (manipulation)
independent variable
-variable changed to see effect on dependent variable
internal validity
-keeping everything beside the independent variable the same in all conditions
random assignment
- everyone has equal chance of taking part in any condition
- ensres that differences in participant traits are distributed evenly
probability level (p-value)
- tells if results occurred by chance and no b/c of IV
- if differ significantly than expected by chance -> IV caused difference
