Study Notes
Sensitive Data Protection
- Sensitive personal data requires strong protection, including health data, genetic or biometric data, religion, race, ethnicity, and political beliefs.
Dealing with Data: Research Approaches
- p-hacking: Using research degrees of freedom to obtain a p-value less than 0.05.
- Averaging across stimuli: May hide differences between individual stimuli.
- Stimulus sampling: Essential when individuals are aware of variations within a category.
- Correlational designs: Describe social reality, suitable for questions like "Which groups in society are not following coronavirus measures and why?".
- Experimental designs: Test causal relationships, suitable for questions like "Do social norms affect people's willingness to get tested and self-quarantine?".
The Importance of Experiments
- Random assignment: Eliminates individual differences between participants in different conditions.
- Theory and intervention: Experiments are crucial for developing theories and effective interventions/policies.
- Manipulation checks: Validating the experimental manipulation in a separate study is often beneficial.
- Attrition: Avoid losing participants, even if the rate is equal across conditions.
- Demand effects: Participants may guess the research question and alter their behavior to support the hypothesis.
- Cover story: Construct a convincing cover story to mask the true research question and minimize demand effects.
- Experimenter blindness: Ideally, the experimenter should be unaware of the experimental condition to prevent conscious or unconscious signaling.
Example: Priming and Walking Speed
- Priming participants with the 'old' stereotype can result in them walking more slowly after the experiment.
Moderation Analysis
- Moderation analysis helps determine the magnitude and direction of an interaction effect.
- The interaction effect is significant if the increment in the squared multiple correlation (R2) is greater than zero.
