Aim
Whether taxi drivers do have a larger right posterior hippocampus and thus see whether navigational memory is stored there.
1 of 8
Partcipants
16 male right handed licensed taxi drivers (18 months) and had a mean age of 44, they also passed the knowledge which took them two years. Control group-50 right handed male on-taxi drivers. Both groups fit and healthy.
2 of 8
Methodology
Quasi experiment: although no manipulation was made. Data was collected through VBM and pixel counting.
3 of 8
Results
Analysing VM showed increase amounts of grey matter in the right hippocampus whereas the control group had a greater volume in the anterior hippocampus. Also the longer the taxi drivers were the larger the posterior hippocampus.
4 of 8
Conclusion
There was a correlation between the amount of cab driving experience and the volume of grey matter in the right hippocampus- correlation analysis
5 of 8
Strengths
Use of scientific equipment reduces human error and tells the truth about the brain from any effect of demand characteristics= reliable and valid. Also Age matched participants cancels out intelligence and age extraneous variables = more reliable.
6 of 8
Weaknesses
They did not take extraneous variables into account. Also pixel counting can have human error.
7 of 8
Usefulness
Results show evidence of plasticity in the brain and it's response to change.
