Understanding Assumptions in Psychological Research

Feb 24, 2025

Lecture Notes: What is Science? Series - Part 3

Introduction

  • Focus on assumptions that guide research in psychology.
  • Importance of assumptions: Constrain fields of study to manage research effectively.

Common Steps in Problem Solving

  1. Define the Problem: Identify what you're interested in.
  2. Select Factors: Choose specific aspects to examine.
  3. Formulate Questions: Develop questions that will provide needed information.
  4. Choose Methodology: Select appropriate research forms and data collection methods.
  5. Understand Assumptions: Clarify what's important in the field to guide questions and methods.

Importance of Assumptions

  • Assumptions help explain different viewpoints and approaches.
  • Encourages respect and understanding of differing perspectives.

Historical Influences on Psychology

  • Early Greek Assumptions:
    1. The world is systematic and predictable.
    2. Humans are part of the world and can be studied similarly.
    3. Explanations should be based on observable events, not magic.
  • These formed the basis for determinism and positivism.

Determinism

  • Nature is Lawful: Universe operates on laws (Einstein's perspective).
  • Causal Relationships: Specific causes lead to specific effects.
  • Finite Causes: Limited set of causes explain phenomena.
  • Discoverable Causes: Belief that causes can be understood drives research.

Challenges to Determinism

  1. Probabilistic Determinism: Causes exist, but may not be fully known.
  2. Chaos Theory: Small changes can lead to significant outcomes.
  3. Uncertainty Principle: Measurement affects the phenomenon being measured.

Additional Influences on Psychology

  1. Mechanism: Treating mental processes as mechanical systems.
  2. Dualism: Mind and brain as separate entities.
  3. Reductionism: Understanding small parts to build understanding of the whole.
  4. Construction and Representation: Building internal models from external stimuli.

Practical Aspects of Research

  • Bias and Accuracy: Verify data accuracy and bias.
  • Analysis and Assumptions: Ensure correct analysis and acknowledge assumptions.
  • Replication: Test trustworthiness through replication.
  • Generalizability: Determine if findings apply beyond the lab.
  • Contribution to Theory: Assess if research contributes to theoretical frameworks.

Conclusion

  • Completion of the series.
  • Upcoming discussion session instead of a lecture or quiz.

These notes capture the key concepts and ideas presented in the lecture on assumptions guiding psychological research, historical influences, and practical research concerns.
