They went through a lot of training and weren't able to become a taxi driver unless they
remembered these routes
They had to remember 320 routes and 25,000 roads
They trained for hundreds of hours on a small motorbike
They practiced spatial navigation intensively everyday
AIM
To investigate whether taxi drivers would have different hippocampi to non taxi drivers
METHOD
Quasi experiment - comparing people's data
DESIGN
Matched pairs design - matched the ages of participants
DATA
Correlational data - investigated the relationship between the hippocampus volume and
the length of time as a taxi driver
INDEPENDENT VARIABLE

DEPENDENT VARIABLE
The volume of the hippocampi from the MRI scan
CONTROLS

PARTICIPANTS
16 right handed male taxi drivers between the ages of 33 and 61 (self-selected sample)
16 right handed male aged matched non taxi drivers (opportunity sample)
PROCEDURE
Data from the MRI (3D image)scan was analysed using VBM (voxel based morphometry) of
pixel counting (Pixel counting works by counting the pixels within a 2D image) method (used
to measure the density of grey matter in the brain)
investigated a relationship between the brain scans and the length of time the taxi drivers
