The 20 questions

  1. Which research method involves an in-depth investigation of a single individual or small group?

    • Content analysis
    • Case study
    • Structured interview
    • Naturalistic observation

  2. Which type of data is a major strength of case studies due to its depth?

    • Representative sample data
    • Rich qualitative data
    • Standardised numerical data
    • Controlled quantitative data

  3. What key limitation affects the generalisability of findings from a case study?

    • Observer bias
    • High ecological validity
    • Small sample size
    • Demand characteristics

  4. Case studies are particularly valuable in psychology for investigating which phenomenon?

    • Standardised behaviours
    • Rare conditions
    • Population trends
    • Causal relationships

  5. Why might retrospective data gathered in a case study be unreliable?

    • Investigator bias
    • Small sample size
    • Inaccurate participant memory
    • Unclear categories

  6. Why is it difficult to establish cause-and-effect relationships in case studies?

    • Demand characteristics
    • Uncontrolled extraneous variables
    • Standardised test procedures
    • Qualitative data reliance

  7. Which key feature distinguishes a case study from a lab experiment?

    • Random participant allocation
    • Double-blind design
    • Manipulation of variables
    • In-depth individual focus

  8. Studying a single child raised in extreme isolation to investigate language acquisition is an example of what?

    • A pilot study
    • A case study
    • A content analysis
    • A lab experiment

  9. How can findings from an exploratory case study contribute to future psychological research?

    • Replacing lab experiments
    • Proving causal relationships
    • Generating new hypotheses
    • Establishing population validity

  10. Why do case studies typically suffer from low population validity?

    • Rigid variable control
    • High investigator bias
    • Small, unique sample
    • Poor ecological validity

  11. What term describes combining multiple data sources, such as interviews and medical records, in a case study?

    • Counterbalancing
    • Operationalisation
    • Stratification
    • Triangulation

  12. Why can case studies not firmly establish causal relationships between variables?

    • Purely quantitative data
    • Large sample sizes
    • Variables are unmanipulated
    • Random participant assignment

  13. What type of bias occurs when a researcher's expectations influence their interpretation of case study data?

    • Investigator bias
    • Social desirability bias
    • Publication bias
    • Sampling bias

  14. How can a single case study successfully challenge an established psychological theory?

    • Establishing statistical significance
    • Providing a counterexample
    • Standardising test conditions
    • Ensuring high reliability

  15. Ethical guidelines require that case study participants' identities are protected. Which principle does this reflect?

    • Standardisation
    • Confidentiality
    • Counterbalancing
    • Random allocation

  16. Which ethical issue is most frequently encountered when publishing longitudinal clinical case studies?

    • Informed consent failure
    • Breach of confidentiality
    • Physical harm
    • Lack of debriefing

  17. What is a major limitation of applying findings from one case study to a wider population?

    • High demand characteristics
    • Low internal validity
    • Investigator bias
    • Low generalisability

  18. What type of data is most commonly gathered during a case study?

    • Qualitative data
    • Inferential data
    • Quantitative data only
    • Nominal data only

  19. Why are findings from a unique single-case study difficult to generalise?

    • Unrepresentative sample
    • Quantitative data
    • Lack of standardisation
    • High ecological validity

  20. Which process involves using multiple sources of evidence to validate case study findings?

    • Triangulation
    • Operationalisation
    • Counterbalancing
    • Standardisation
