The 20 questions

  1. What biological factor refers to genetic tendencies passed down from parents that increase addiction risk?

    • Social learning
    • Classical conditioning
    • Peer pressure
    • Hereditary factors

  2. An inherited risk that makes a person more likely to develop an addiction is called what?

    • Genetic determinism
    • Genetic vulnerability
    • Neural adaptation
    • Environmental trigger

  3. What measure of similarity between twin pairs did Kaij calculate in his alcohol abuse study?

    • Percentage difference
    • Standard deviation
    • Correlation coefficient
    • Concordance rate

  4. What percentage of genetic material do monozygotic (identical) twins share?

    • 75%
    • 25%
    • 50%
    • 100%

  5. What did Kaij conclude about alcohol abuse from higher twin concordance?

    • Genetic influence exists
    • Addiction is purely cultural
    • Genetics is irrelevant
    • Environment causes all addiction

  6. Why is isolating genetic influences difficult in twin addiction studies?

    • Twins share environments
    • Sample sizes are zero
    • Addiction cannot be measured
    • Twins have different DNA

  7. Is hereditary vulnerability to addiction an example of a nature or nurture explanation?

    • Social
    • Nature
    • Nurture
    • Environmental

  8. Which debate considers whether addiction stems from biology or experience?

    • Nature versus nurture
    • Free will versus determinism
    • Reductionism versus holism
    • Idiographic versus nomothetic

  9. What percentage of genes do dizygotic (non-identical) twins share on average?

    • 0%
    • 100%
    • 50%
    • 25%

  10. What type of twins did Kaij compare against dizygotic twins in his alcoholism study?

    • Fraternal twins
    • Conjoined twins
    • Monozygotic twins
    • Adopted twins

  11. What pattern of concordance rates in twin studies supports a genetic cause for alcohol abuse?

    • Lower MZ concordance
    • Higher MZ concordance
    • Equal concordance
    • Higher DZ concordance

  12. Which factor does a purely genetic explanation of addiction ignore?

    • Neurochemistry
    • Environmental influences
    • Brain structure
    • Inherited genes

  13. In the nature versus nurture debate, what does 'nurture' represent in causing addiction?

    • Brain chemistry
    • DNA mutations
    • Genetic inheritance
    • Environmental factors

  14. Which term refers to an inherited biological trait that increases addiction risk?

    • Operant conditioning
    • Peer pressure
    • Genetic vulnerability
    • Social learning

  15. What confounding variable makes twin study results difficult to attribute purely to genes?

    • Brain damage
    • Unrelated DNA
    • Shared environment
    • Sample bias

  16. In twin studies like Kaij's, what does the term 'concordance rate' measure?

    • Brain size difference
    • Similarity between twins
    • Sample size
    • Twin age gap

  17. How do inherited genetic factors affect the likelihood of developing addiction?

    • They guarantee addiction
    • They prevent addiction entirely
    • They have zero effect
    • They increase risk

  18. What assumption in twin studies suggests MZ and DZ twins experience identical upbringings?

    • Twin divergence hypothesis
    • Equal environment assumption
    • Gene-environment interaction
    • Concordance rule

  19. What does having a genetic vulnerability to addiction mean?

    • Immune deficiency
    • Guaranteed outcome
    • Certain addiction
    • Higher biological risk

  20. Which approach combines biological predisposition with environmental triggers to explain addiction?

    • Interactionist approach
    • Reductionist approach
    • Cognitive approach
    • Behaviourist approach
