1Aims1. To find out whether the structure of the brain changes in response to environmental demand
2. To find out whether structural changes in the hippocampus can be detected in people with extensive navigation experience
2Approach/perspectivePhysiological approach- brain structure
3Method and designnatural experiment, independent design, correlational research
4Independent variableLondon taxi driver (brain) or non- taxi driver (brain)
5Dependent variableStructure and volume of hippocampi
6Sample- Group 116 right-handed, male taxi drivers, average age 44, all licensed more than 18 months, average time as taxi driver 14.3 years
7Sample- Group 216 right- handed males, age matched non-taxi drivers
8Procedure- Stage 1MRI scans of brains of 50 healthy right handed male non taxi drivers aged 33-62 were analysed to establish a comparison database of average hippocampi (analysis by VBM)
9Procedure stage 2MRI scans of brains of 16 taxi drivers and of 16 matched control were analysed by VBM and compared with this database
10ControlsBlind coder (Expert didn't know the MRI scans was of a taxi driver or not)
