During their investigation into hippocampal volume in London taxi drivers, Maguire et al. (2000) conducted both a quasi-experimental comparison with control participants and a correlational analysis against driving experience. Which of the following statements accurately summarizes their findings regarding the anterior and posterior regions of the hippocampus?
Taxi drivers had a greater volume of grey matter in the anterior hippocampus than controls, and this volume showed a positive correlation with time spent working as a driver.
Taxi drivers had a greater volume of grey matter in the posterior hippocampus than controls, and this volume showed a negative correlation with time spent working as a driver.
Controls had a greater volume of grey matter in the posterior hippocampus than taxi drivers, and this volume showed a positive correlation with time spent working as a driver.
Controls had a greater volume of grey matter in the anterior hippocampus than taxi drivers, and anterior hippocampal volume in drivers showed a negative correlation with time spent working as a driver.
