Study Notes
Goals of Observational Research
- Aims to provide a comprehensive or selective description of behavior.
Comprehensive Records of Behavior
- Narrative records consist of written descriptions, audio, and video recordings.
- Data organization and classification are crucial for hypothesis testing.
- Observers must document behaviors during or shortly after observations.
- Example: Video recordings analyze mother-child interactions in maltreating vs. non-maltreating families.
- Hartup's study of children's aggression utilized narrative records for documentation.
Selected Records of Behavior
- Focuses on quantifying specific behaviors/events, measuring frequency or duration.
- Measurement scales include nominal, ordinal, interval, and ratio.
Measurement Scales
- Nominal Scale: Lowest measurement level; categorizes events (e.g., eye colors).
- Ordinal Scale: Ranks events but lacks precise differences; example includes race outcomes without exact timings.
- Interval Scale: Specifies distances between events but lacks a true zero; allows standard arithmetic operations (e.g., test scores).
- Ratio Scale: Includes all properties of interval scales with an absolute zero; meaningful comparisons of ratios (e.g., weight).
Electronic Recording and Tracking
- Uses devices for measurements in natural settings (e.g., ambulatory blood pressure monitors in studies).
Data Analysis of Observational Data
- Qualitative analysis involves coding behaviors into categories.
- Quantitative analysis includes descriptive statistics based on measurement scales.
- Observers assess interobserver reliability to ensure consistency in data collection.
Behavior Influences
- Reactivity: Observer presence can alter participant behavior, referred to as demand characteristics.
- Techniques to mitigate reactivity:
- Concealed observation or disguised participant observation.
- Habituation: Participants adjust to an observer over time.
- Desensitization: Reduces emotional response through repeated exposure.
Ethical Considerations
- Informed consent is essential.
- Privacy and confidentiality must be maintained.
Observer Bias
- Arises from researchers’ preconceived ideas affecting behavior selection and recording.
- Reducing bias strategies include limiting information given to observers and keeping them unaware of certain study aspects.
