Methods Flashcards
Science is logical
Science is repeatable
Science is vulnerable to disconfirmation
3 Features of science
An integrated set of statements that describes, predicts, or explains behavior
theory
Specific, testable, and disconfirmable statements about the behavior we want to study or theory we want to test
hypothesis
Conceptual representation of behaviors or phenomenon around which research is based; the thing you’re interested in studying
Ex: Love, aggression, and groups– abstract representations that are intangible and do not exist in physical reality
construct
Defines a construct in concrete terms
Ex: anger –> throwing a chair at your boss
Operationalization
Describe, predict, explain behavior
Goals of research
Naturalistic observation/ethnography
Observe behavior where it typically happens
Describing behavior
High in external validity
See what people actually do
Strengths of describing behavior
Can only describe
No private/rare events
Observer bias
Low in internal validity
Limitations of describing behavior
Correlational studies
Determine how much and in what way two pre-existing variables are related
Predicting behavior
Study things you can’t or shouldn’t manipulate
Lots of data
Cheap and easy
Strengths of predicting behavior
Response bias– people can lie or aren’t aware of their bias
Sampling errors
Cannot interpret causality
Could be other factors that correlate things
- Ex: correlation between coffee and heart attacks- does not include amount of sleep, stress, sugar consumed, etc.
- Ex: positive correlation between ice cream sales and homicide rates- does not include heat, population density, etc.
Limitations of predicting behavior
- Experiments
- Manipulate one or more factors while controlling others (holding things constant)
Explaining behavior
High in internal validity
Can conclude causality
Strengths of explaining behavior
Expensive
Demand characteristics
Low in external validity
Limitations of explaining behavior
