Practice question · Multiple choice
London taxi drivers who have memorised the city's street layout show a measurably larger posterior hippocampus, and it grows over training. What does that establish?
Hints
- A selection explanation would predict the difference exists before training. Ask what the longitudinal data show.
- The structure changed WITH training. What does that rule out?
Show the answer
C. That intensive spatial learning reshapes the structure supporting it
Why
Following trainees over time is what rules out selection: the difference appears as the Knowledge is learned, and shrinks in retired drivers. Structure follows use, which is why this study is cited far outside neuroscience, it is one of the cleanest demonstrations that adult brains are shaped by what is demanded of them.
