Maguire Flashcards
Aim
To investigate whether doing a job that demands navigational experience, and spending more years in that job, affect the volume of the hippocampus
Describe sample
16 right handed male taxi drivers
What was the range of experience of the drivers?
1.5-42 years
What was the IV?
Taxi driver or not
What was the control sample
50
What was the dependant variable
Volume of hippocampus
Name 2 controls
Matching participants in age, gender and handedness
Experienced individual who measures brain volume was blind to participants condition
What technique was used to compare scans
VBM
How was volume of brain measured
Pixel counting (how many pixels occupied by hippocampal tissue)
Why was one taxi driver removed in the correlational analysis?
His experience was much greater (42 years compared to next highest 28 years)
Which part of the brain increased in volume the longer you had been a taxi driver?
Posterior hippocampus
Conclusion
Distribution of grey matter in the hippocampus changes with use
