Maguire Flashcards
What is the function of the posterior hippocampus
deals with old memories
what is the function of the right hippocampi
holds mental maps
what is the function of the anterior hippocampus
deals with new memories
what is the function of the left hippocampi
compliments its partner by storing memories eg people and events that occur
what is the aim of this study
aimed to show that the hippocampus in the human brain is the structure associated with spatial memory and navigation
what is the method
quasi experiment
what is the iv of this study
whether the person was a taxi driver or a
what is the dv of this study
the volume of the hippocampi measured by analysing mri scans of the participants brain using the VBM and the pixel counting
what is the design
independant measures design and matched pairs design
what is the sample
16 taxi drivers were all healthy right handed male london drivers with a mean age of 44
what is the control group
they did not drive taxis
50 for the vbm analysis 16 for the pixel counting
were matched for health, handedness, sex and mean age
opportunity sample from mri data base
what does the vbm do
identifies differences in grey matter density in different regions of the brain. and then they were compared to those of the 50 non taxi drivers scans
what are the controls
participants were all scanned using the same scanner
person counting the pixels was blind to whether the brain belonged to a taxi driver or control participant
what were the results
taxi drivers had significantly increased grey matter volume in the right and left posterior hippocampi than the controls
what are 2 smilairites between maguire and blakemore
quantatative data
high internal reliability
