    Study Notes

    Research Methodology in Psychology

    Basic and Applied Research

    • Psychologists conduct basic research to gain knowledge about a phenomenon or behavior, with little emphasis on real-world application
    • Applied research investigates a phenomenon or behavior in the real world to answer a specific question or solve a problem
    • Basic research aims to understand human development, while applied research focuses on solving real-world problems, such as developing therapy to treat eating disorders

    Theories in Psychology

    • A theory is a set of related statements that explain various occurrences
    • Theories are created and invented through research, explaining and predicting relationships between variables
    • Theory guides research, organizes ideas, and generates new research
    • Examples of psychological theories: Theory of Reasoned Action, Health Belief Model, Stress Theory, Erikson's Psychosocial Developmental Theory, Piaget's Cognitive Developmental Theory, Trait Theory of Personality, and Humanistic Theory of Personality

    Hypotheses

    • A hypothesis is a formal statement of expected relationships among variables
    • A hypothesis predicts a relationship between two or more variables, is testable, and can be refuted or confirmed
    • There are two types of hypotheses:
      • Null hypothesis: represents a statement of no relationship among variables
      • Scientific hypothesis (alternate/working/researcher's hypothesis): represents a predicted relationship among variables
    • Hypotheses can be simple (two variables) or complex (more than two variables), and can be directional or non-directional

    Characteristics of Scientific Research

    • Control: eliminating extraneous variables that can affect an experiment
    • Operational definition: specifying the independent and dependent variables and how extraneous variables will be controlled
    • Replication: ensuring that results can be reproduced

    Steps in Scientific Methodology

    • Identify a problem and formulate a hypothesis
    • Design the research
    • Conduct the research
    • Test the hypothesis
    • Communicate the research results

    Researchable and Non-Researchable Topics

    • Researchable topics can be empirically investigated and state a testable hypothesis
    • Non-researchable topics include explanations, vague propositions, philosophical or ethical issues, or opinions
    • Examples of researchable topics: effect of feedback on task performance, approaches to ensuring cleanliness on campus, and effect of knuckle-cracking on osteoarthritis development
