  1. Chapter 2 Research

  2. Psychology is a Social Science • Hypotheses, observation, testing, and experimentation are used. SAME as science • Exceptions to a generalization do not necessarily negate the hypothesis. Human behavior is complex. DIFFERENT

  3. Research Terms • Experiment: a specific type of scientific study used to determine if one variable has a casual effect upon another variable. • Placebo: a medicine with no active ingredients works by the power of suggestion. • Thesis: statement or question to study. Looks at psychological principle • Hypothesis: a statement of the results that the experimenter expects. Prediction

  4. Example • Thesis question: Is yawning contagious? • Hypothesis: If one person yawns in class, then others will repeat this behavior

  5. Variables: factors that change in an experiment. Independent Variable: the factor the researcher changes or varies in a study. (If) Dependent Variable: the factor that will change as a result of what the other factor does. (Then)

  6. Independent Variable: Yawn prompt Dependent Variable: other’s behavior (yawn or no yawn)

  7. Experimental group: the group on which the critical part (variable introduced) of the experiment is performed. Control group: the group that does not participate (no variable) in the critical part of the experiment.

  8. Control Group: Classroom with no yawn prompt Experimental Group: Classroom with yawn prompt

  9. Laboratory study Field study Survey method Naturalistic observation Interview Case study Psychological test Longitudinal Cross-sectional Methods of Research (p.41) Experiment: Bi-lateral Transfer
