The aim of Maguire’s London taxi driver’s 2000 quasi experiment was to investigate whether changes could be detected in the brains of London taxi drivers, and to further investigate the functions of the hippocampus in the spatial memory. The independent variable in this researched experiment is to test the same amount of London taxi drivers and the study is an example of a quasi or natural experiment because the researchers are comparing the data of taxi drivers and non-taxi drivers. The researchers have no control of this variable as it is naturally occurring. The method of this experiment was to take 16 healthy, right-handed, licensed male London taxi drivers. The taxi drivers were compared with the scans of 50 healthy right-handed males who did not drive taxis. All of the participants had been licensed London taxi drivers for more than one and a half years The data were collected using imaging (MRI) which collects data about the structure or anatomy of the brain. Pixel counting was carried out on the scans of the 16 taxi drivers and 16 age-matched controls taken from the 50 control participants. Pixel counting consists of counting the pixels in the images provided by the MRI scans. Areas were calculated by taking images of slices of the whole length of the hippocampus. That in the London taxi drivers the volume of the posterior hippocampus expanded because of their dependence on navigation skills. Maguire et al. argue that the anterior and posterior hippocampus have different roles. The first main findings of the research were that the posterior hippocampi of taxi drivers were significantly larger relative to those of control subjects and that the anterior hippocampal region was larger in control subjects than in taxi
