The 20 questions

  1. Why is assuming identical brain structure across individuals problematic in case studies?

    • Brains never change
    • Neurons stop growing
    • Damage is uniform
    • Brain organisation varies

  2. Which individual difference factor can significantly affect a patient's recovery from brain damage?

    • Eye colour
    • Body height
    • Age of patient
    • Blood type

  3. According to Freud, why do individual differences in human personality develop?

    • Varying personality balance
    • Uniform parenting styles
    • Shared hormonal levels
    • Identical genetic inheritance

  4. According to evolutionary psychology, why did specific developmental traits evolve in humans?

    • Aided survival reproduction
    • Eliminated aggressive drives
    • Created identical personalities
    • Prevented genetic mutations

  5. Which key stage of human physical development is directly driven by rising hormone levels?

    • Object permanence
    • Language acquisition
    • Puberty
    • Moral development

  6. What biological property allows another brain area to take over functions after damage?

    • Hemispheric lateralisation
    • Synaptic pruning
    • Neural degeneration
    • Brain plasticity

  7. Why do younger brains often recover better from injury than adult brains?

    • Greater brain plasticity
    • Larger brain volume
    • Superior synaptic pruning
    • Lower hormone levels

  8. According to Freud, individual differences in personality develop through which component?

    • Testosterone fluctuation
    • Biological evolution
    • Superego development
    • Genetic mutation

  9. Assuming all brains function identically when interpreting brain-damage case studies creates what issue?

    • Overgeneralisation of results
    • Increased experimental control
    • Demand characteristics
    • High ecological validity

  10. Why is generalising from a single brain-damaged patient to all humans problematic?

    • Prevents statistical analysis
    • Lacks ethical approval
    • Causes researcher bias
    • Ignores individual differences

  11. Which hormone increase during pubertal development is linked to rising adolescent aggression?

    • Testosterone
    • Oestrogen
    • Insulin
    • Melatonin

  12. What key feature suggests a developmental behaviour evolved as an adaptation?

    • Unique to individuals
    • Purely learned socially
    • Culturally restricted
    • Universal across cultures

  13. Which term describes explaining aggression using both biological factors and environmental influences?

    • Interactionist approach
    • Psychodynamic reductionism
    • Social constructivism
    • Behaviourist approach

  14. What is a major criticism of strictly biological explanations of developmental aggression?

    • Overemphasises conscious choice
    • Lacks objective measures
    • Ignores environmental influences
    • Requires longitudinal testing

  15. How can researchers account for individual differences when studying brain-damaged patients?

    • Eliminate control groups
    • Use animal subjects
    • Study diverse samples
    • Test single cases

  16. Assuming all adolescents respond identically to rising testosterone levels overlooks what factor?

    • Internal validity
    • Individual differences
    • Biological determinism
    • Inferential statistics

  17. Why do developmental psychologists use longitudinal designs to study biological changes over time?

    • Requires less time
    • Tracks same individuals
    • Prevents participant attrition
    • Eliminates demand characteristics

  18. Why are biological explanations of aggression considered reductionist?

    • Ignores animal studies
    • Proves nurture matters most
    • Always completely invalid
    • Oversimplifies complex behaviour

  19. When in human development is neural plasticity at its highest level?

    • Early childhood
    • Adolescence
    • Late adulthood
    • Old age

  20. Which ethical requirement is essential when conducting brain-injury research on children?

    • Parental consent
    • Participant debriefing
    • Single-blind setup
    • Deception
