  1. Psychology Research Methods Tuesday: Bring Headphones!!

  2. Sample • The small group of participants, out of the total number available that a researcher studies.

  3. Naturalistic Observation • Method in which psychologists observe the subject in a natural setting without interfering. • Examples : Jane Goodall

  4. Case Study • Method that involves an intensive investigation of one or more participants. • Example: Freud

  5. Surveys • Method in which information is obtained by asking many individuals a set of fixed questions. • Example: Voting Projections

  6. Longitudinal Study • Method in which data is collected about a group of participants over a number of years to assess how certain characteristics change or remain the same during development. • Example : Mr. Hannah follows you to college

  7. Cross-Sectional Studies • Method in which data is collected from groups or participants of different ages and compared so that conclusions can be drawn about such differences due to age. • Tracking learning abilities at different ages.

  8. Experimentation

  9. Researcher controls the situation to analyze samples. • Example : Creating a simulation of a fight to test the bystander theory.

  10. Some Experimentation Terms

  11. Self-fulfilling prophesy • Situation where a researcher’s expectations influence the sample’s behavior, making an inauthentic experiment. • Examples: Counting horse, Inkblots

  12. Single-Blind Experiment • Experiment where the participants are unaware of which participants received the treatment. • Example: Milgram Experiment

  13. Double-Blind Experiment • An experiment which neither the experimenters nor the participants know which participants received the treatment. • How could this be more authentic than a single blind experiment?

  14. Placebo Effect • A change in a participant’s illness or behavior that results from a belief that the treatment will have an effect, rather than the actual treatment.

  15. Reflection • Which research method do you think is best? (naturalistic observation, survey, case study, experiment, longitudinal, cross-sectional)
