    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.
