Study Notes

Research Methods in Psychology

Confounds: Alternative explanations for differences between experimental and control groups, excluding the independent variable.
Confederate: An actor in a study who plays a specific role, perceived by participants as another participant.
Biases of Intuition:
- Thinking the easy way: Preference for simpler, believable ideas over complex conclusions.
- Thinking what we want: Confirmation bias leads to incorrect conclusions by not challenging existing beliefs.
Cherry Picking the Evidence: Selecting only evidence that aligns with one’s existing beliefs while ignoring contrary information.
Availability Heuristic: The tendency to rely on immediate examples that come to mind, resulting in biased thinking based on vivid or recent memories.
Over-confidence Bias: A tendency to be excessively confident in one's conclusions, regardless of actual accuracy, exemplified by eyewitness testimony.
Confirmatory Hypothesis Testing: The practice of asking leading questions that are likely to elicit desired responses, thereby reinforcing subjective beliefs.
Controlled Studies vs. Observational Studies:
- Controlled studies involve manipulation of independent variables and comparison to control groups.
- Observational studies involve behavior observation without manipulation.
Importance of Comparison/Control Groups: Essential for assessing the effects of the independent variable, must maintain identical conditions to validate results.
Conceptual Definition: Abstract interpretation of variables, such as "Depression" or "Debt stress," which require clear definitions for research.
Independent Variable: The variable manipulated in an experiment to observe its effects.
Dependent Variable: The variable measured in response to changes in the independent variable.
Anecdotal Claims: Personal stories or solutions to problems lacking statistical backing and based on individual experience.
Types of Claims:
- Frequency Claim: Reports how common or frequent something is.
- Association Claim: Indicates a relationship between variable changes.
- Causal Claim: Asserts that one variable causes a change in another.
Types of Associations:
- Positive Association: Both variables increase or decrease together.
- Negative Association: One variable increases while the other decreases.
- Zero Correlation: No relationship between the variables.
- Curvilinear Correlation: Pattern changes as one variable increases, such as age affecting healthcare visits.
Construct Validity: Measurement accuracy of variables to ensure they assess what they are intended to measure.
External Validity: The applicability of study results to real-world scenarios, influenced by how populations were sampled.
Statistical Validity: Involves assessing the margin of error, statistical significance, and overall sensibility of results.
Three Rules for Causal Claims:
- Internal Validity: No alternate explanations for changes; only the independent variable affects the dependent variable.
- Rule of Covariance: Changes in the independent variable must correspond with changes in the dependent variable.
- Rule of Temporal Precedence: The independent variable must precede the effect observed in the dependent variable.
Tuskegee Study: Infamous clinical study showcasing ethical violations in research, relevant for discussions on ethics in psychological research.
