2. Scientific Methods Scientific and “everyday” observations differ Goal – to describe behavior as fully and accurately as possible

3. Samples Behavior must be sampled

4. Samples Behavior must be sampled Sample is used to represent the population of all possible behaviors

5. Samples Behavior must be sampled Sample is used to represent the population of all possible behaviors Generalization of observations – generalized to a theory

6. Samples Behavior must be sampled Sample is used to represent the population of all possible behaviors Generalization of observations – generalized to a theory Representative Samples –does it represent the population?

7. Samples Behavior must be sampled Sample is used to represent the population of all possible behaviors Generalization of observations – generalized to a theory Representative Samples –does it represent the population? Time Sampling – different times

8. Samples Behavior must be sampled Sample is used to represent the population of all possible behaviors Generalization of observations – generalized to a theory Representative Samples –does it represent the population? Time Sampling – different times Situation sampling – different situations

9. Using Observational Methods Direct Observation

10. Using Observational Methods Direct Observation – Naturalistic Observation – without intervention

11. Using Observational Methods Direct Observation – Naturalistic Observation – without intervention – Observation with Intervention – participant observation

12. Using Observational Methods Direct Observation – Naturalistic Observation – without intervention – Observation with Intervention – participant observation Reactivity – people react to knowing they are being observed

13. Using Observational Methods Direct Observation – Naturalistic Observation – without intervention – Observation with Intervention – participant observation Reactivity – people react to knowing they are being observed – Disguised –individuals do not know they are being watched

14. Using Observational Methods Direct Observation – Naturalistic Observation – without intervention – Observation with Intervention – participant observation Reactivity – people react to knowing they are being observed – Disguised –individuals do not know they are being watched – Undisguised – individuals know they are being observed

15. Using Observational Methods Structured Observation

16. Using Observational Methods Structured Observation

17. Using Observational Methods Structured Observation Field Experiment

18. Using Observational Methods Structured Observation Field Experiment Confederates – Milgram

19. Using Observational Methods Structured Observation Field Experiment Confederates – Milgram Rosenhan (1973) study on psychiatric diagnosis and hospitalization; what it was like to be “sane” in an “insane” world.

20. Indirect Observational Methods – Researcher does not intervene – Nonreactive because observations made indirectly Examination of physical traces and archival records – Physical Traces (Zechmeister et al., 2001, p. 89). Use Traces Products Biases in the way researchers approach traces

21. Indirect Observational Methods – Archival Records Running Records Natural Treatment Problems with archival records: – Selective Deposit – Selective Survival

22. Recording Behavior Comprehensive Description sought through – Narrative Records Records of Selected Behaviors – Researchers interested in only certain behaviors Measurement Scales – Nominal – Ordinal – Interval – Ratio

23. Nominal Do students study? – Categories are yes and no. Melissa—yes Charles—yes Gina—yes Rose—no Neil—yes Jeff—no

24. Ordinal Who studies more? – Scale adds “more than” or “less than” Melissa studies more than Neil, who studies more than Gina. Gina studies more than Neil, and Neil studies more than Charles. Charles studies more than Rose and Jeff.

25. Interval Who studies more? An observer can rate their studying on a 5-point scale (Never to Always). Melissa—5 (Always) Gina—4 (Usually) Neil—3 (Often) Charles—2 (Sometimes) Rose—1 (Never) Jeff—1 (Never)

26. Ratio Who studies more? – Measure the amount of time – students spend studying Melissa—12 hours a day Gina—8 hours a day Neill—2 hours a day Charles—1 hour a day Rose—0 hours a day Jeff—0 hours a day

27. Analyzing Observational Data Quantitative Data Analysis-numerical – Descriptive Statistics – Reliability Qualitative Data Analysis-verbal – Grounded Theory Method – Data Reduction – Data Display – Conclusion Drawing/Verification

28. Thinking Critically About Observational Research Reactivity – Demand Characteristics Observer Bias – Expectancy Effects
