Study Notes

Why Study Research Methods?

To understand how to conduct and evaluate research
To identify and evaluate false claims
To learn to think like a scientist

Sources of Knowledge

Non-scientific approaches:
- The method of tenacity (repetition)
- The method of intuition
- The method of authority (experts)
- The method of rationalism (logic)
- The method of empiricism (observation)

The Scientific Method

Steps:
- Observation
- Theory
- Hypothesis
- Testable prediction
- Data collection
- Analysis
- Conclusion
- Dissemination
Theory:
- Organizes observations
- Explains observations
- Predicts future events
Conditions for a good scientific theory:
- Parsimony (few concepts, many explanations)
- Precision (clear predictions)
- Testability (empirically verifiable)

Formulating a Hypothesis

Hypothesis: Proposed relationship between variables
Variable: Any characteristic that changes or can take different values (gender, height, depression scores)
Independent variable (IV): Manipulated variable (the cause),
- Example: type of animal (dogs, cats)
Dependent variable (DV): Measured variable (the outcome), the result of manipulating the IV
- Example: test of animal cognition

Generating a Testable Prediction

Prediction: Specific statement about the relationship between variables in a given situation
Deductive reasoning: From general hypothesis to specific prediction

Requirements of a Good Hypothesis

Logical: Founded in existing theories or previous research
Testable: Measurable variables
Refutable: Falsifiable (able to be disproven)

The Research Process

Methods section: Detailed description of how the research was conducted
Results section: Objective reporting of data and statistical analyses
Discussion section: Interpretation and implications of the findings
References: Complete list of all sources cited
Tables and figures: Additional information presented visually

The Peer Review Process

Reviewers: Objective experts in the field
Editorial decisions:
- Revise and resubmit
- Accept
- Reject
Pressure to publish: Publications can influence grants, awards, and tenure
