  • RESEARCH METHOD OF MAGUIRE'S RESEARCH?
    natural experiment
  • DESIGN OF MAGUIRE'S RESEARCH?
    independent groups
  • IV OF MAGUIRE'S RESEARCH?
    taxi driver or not
  • DV OF MAGUIRE'S RESEARCH?
    volume of grey matter in hippocampus
  • SAMPLE OF MAGUIRE'S RESEARCH?
    16 healthy, right-handed, male London taxi drivers who had all completed 'The Knowledge'
  • CONTROL GROUP OF MAGUIRE'S RESEARCH?
    50 healthy, right-handed males who didn't drive taxis
  • PROCEDURE OF MAGUIRE'S RESEARCH?
    1. MRI to scan brains
    2. Uses strong magnetic fields and radio waves to produce detailed images inside brain
    3. Use pictures to measure amount of grey matter in hippocampus
    4. Compared to amount in taxi drivers' brains to control group
  • FINDINGS OF MAGUIRE'S RESEARCH?
    • significantly more grey matter in taxi drivers' hippocampi than in control group
    • number of years they had been a taxi driver positively correlated with the amount of grey matter
  • CONCLUSION OF MAGUIRE'S RESEARCH?
    brain has plasticity and experiences such as driving taxis can cause physical changes in the brain areas involved in memory
  • STRENGTHS OF MAGUIRE'S RESEARCH?
    • objective, scientific measurements (MRI)
    • real world application
    • control group
  • LIMITATIONS OF MAGUIRE'S RESEARCH?
    • cause and effect
    • beta bias
  • OBJECTIVE, SCIENTIFIC MEASUREMENTS ARGUMENT FOR MAGUIRE'S RESEARCH?
    • no demand characteristics/ social desirability
    • increases internal validity
  • REAL WORLD APPLICATION ARGUMENT FOR MAGUIRE'S RESEARCH?
    • help development of treatment
    • for brain trauma patients
  • CONTROL GROUP ARGUMENT FOR MAGUIRE'S RESEARCH?
    • significant difference
    • can establish cause and effect
    • increases internal validity
  • CAUSE AND EFFECT ARGUMENT FOR MAGUIRE'S RESEARCH?
    • did not measure structure of brain before completing 'The Knowledge'
    • may have become taxi drivers due to existing difference
  • BETA BIAS ARGUMENT FOR MAGUIRE'S RESEARCH?
    • only male sample
    • based on men's experiences only
    • results lack generalisability
