Study Notes
Self-Report Measures and Surveys
- Self-report measures assess personal characteristics like personality and mental health.
- Surveys collect information on behaviors, thoughts, and attitudes, often requiring random samples for generalizability.
- Non-random selection can yield biased results and misrepresent broader populations.
Random Selection
- Ensures that each individual in a population has an equal chance of being selected.
- Example: Research on education in Louisiana should represent all demographics.
Self-Report Advantages and Disadvantages
- Pros include ease of administration and direct access to internal thoughts.
- Cons involve potential inaccuracies, especially among narcissists, and risks of dishonesty or socially desirable responding.
Rating Data
- Rating others can reduce self-report biases but can introduce new biases like the halo effect, where one positive trait influences evaluations of others.
Case Study Designs
- Case studies focus on individual subjects over time, useful for studying rare phenomena but may be anecdotal and misleading.
Correlational Designs
- Examines relationships between variables, without establishing cause and effect.
- Correlations can be positive, negative, or zero and are typically depicted in scatterplots.
- Illusory correlations occur when perceived relationships do not exist, such as crime rates and lunar phases.
Experimental Design
- Experiments manipulate an independent variable to observe effects on a dependent variable.
- Random assignment is crucial for reliable results; confounds can introduce biases.
- Placebo and nocebo effects illustrate the power of expectation on outcomes.
Pitfalls of Experimental Design
- Experimenter expectancy effect can bias results; double-blind designs can mitigate this effect.
- Demand characteristics can lead participants to guess the purpose of a study, potentially skewing results.
Evaluating Psychological Research
- Peer review process identifies research flaws.
- Consider confounding variables, placebos, and the distinction between correlation and causation.
Modern Ethical Guidelines
- Research must pass an Institutional Review Board (IRB) review, ensure informed consent, justify deception, and provide debriefing to participants.
Historical Ethical Issues
- The Tuskegee Study (1932-1972) exemplified ethical violations, where participants were not informed or treated for syphilis, leading to severe health consequences.
Animal Research
- Governed by Institutional Animal Care and Use Committee (IACUC) protocols; a small percentage of psychological research involves animals, primarily rodents and birds.
Statistics: Descriptive Statistics
- Key measures include central tendency: mean, median, and mode, which describe data clustering behavior in a dataset.
