Maguire et al study

What was the sample size of the taxi driver group in the Maguire et al. study?

• 50

• 16

• 32

• 18

What was the criteria for selecting participants in the experimental group?

• All had driven for over 10 years

• All were left-handed males

• All were London taxi drivers who had passed 'The Knowledge'

• All had previous brain scans

What was the age range of the taxi driver participants?

• 18–44 years

• 20–60 years

• 32–62 years

• 30–50 years

What was the nature of the study method?

• Experimental

• Quasi-experimental

• Correlational

• Longitudinal

Which two techniques were used to analyze the MRI data?

• EEG and CT scans

• PET and fMRI

• VBM and Pixel Counting

• DTI and Lesion Mapping

What does Voxel-Based Morphometry (VBM) measure?

• The length of the hippocampus

• Brain activity during navigation tasks

• Density of grey matter in the brain

• Electrical activity in the neurons

What did pixel counting reveal about the hippocampus of taxi drivers?

• Smaller overall hippocampus compared to controls

• No difference in hippocampus size

• Larger anterior hippocampi

• Larger posterior and smaller anterior hippocampi

What correlation was found through the use of VBM?

• A decrease in brain volume with longer taxi driving experience

• Right posterior hippocampus volume increased with years spent as a taxi driver

• An increase in overall brain mass

• More driving years linked to smaller anterior hippocampus

How many participants were in the control group?

• 16

• 25

• 50

• 32

What characteristic was shared by both the taxi drivers and the control group participants?

• All were bilingual

• All were right-handed males

• All had MRI scans before driving

• All had a university degree
