Research Methods in Social Psychology
  • I. Develop a research question
  • II. Develop a hypothesis
    • A hypothesis is a testable prediction that describes relationships between events.
  • III. Research Design
    • Operational definitions specify how to measure concepts.

Research Methods in Social Psychology (cont.)
  • A. Correlational Research Designs
    • Correlation involves assessing the relationship between two or more variables
    • Correlation coefficient ranges from -1 to +1
      • Number gives the strength of the relationship
      • Sign gives the direction of the relationship
interpreting correlational results
Interpreting correlational results:
  • Correlation does not imply causation!
  • Two problems in establishing cause-effect:
    • Directionality problem – Does A cause B or does B cause A?
    • Third variable problem – C may cause both A and B
evaluating research
Evaluating Research
  • Internal Validity: the degree to which a research finding provides clear or compelling information about causality.
  • External validity: the degree to which a research finding provides an accurate description of what typically happens in the real world.
evaluating research cont
Evaluating Research (cont.)
  • To increase the external validity of a laboratory study, increase:
  • Mundane realism: degree to which the experimental conditions resemble real-world situations.

AND/OR

  • Experimental realism: degree to which the experimental conditions are psychologically engaging.
experimental research
Experimental Research
  • Studies that seek to establish cause-effect relationships by manipulating one or more factors while holding others constant.
  • Independent variable (IV) – the variable that is manipulated by the experimenter.
    • Experimental group – treatment
    • Control group – no treatment
  • Dependent variable (DV) – the variable that is measured as an outcome.
experimental research cont
Experimental Research (cont.)
  • Two essential ingredients of an experiment:
    • Random assignment – each participant has an equal chance of being in the experimental group or the control group
    • Holding the other variables constant – the only difference between groups should be the manipulated variable: Everything else must be held constant
factorial design
Factorial Design
  • A design in which the levels of 2 or more independent variables are completely crossed.
main effect
Main effect
  • A statistical term meaning that, overall, an independent variable has an effect on a dependent variable.
interaction
Interaction
  • A statistical term meaning that the effects of one independent variable on a dependent variable depend on the level of another independent variable.
  • The effects of _____ on _______ depend on ______.
ethics
Ethics
  • 1. Deception is allowed, but the benefits of the research must outweigh the costs.
  • 2. If deception is used, participants must be promptly debriefed at the end of the experiment.
  • 3. Researchers must obtain informed consent. Participants are to be informed of any risks of benefits of participating in the study and that they may withdraw at any time without penalty.
  • 4. Researchers must ensure the confidentiality of data.
