London taxi drivers have to undertake years of intense training known as “the knowledge” to gain their operating license, including learning the layout of over twenty-five thousand of the city's streets. A researcher and her team investigated the taxi drivers and the ordinary people. The two groups were asked to watch videos of routes unfamiliar to them through a town in Ireland. They were then asked to take a test about the video that included sketching out routes, identifying landmarks, and estimating distances between places. Both groups did well on much of the test, but the taxi drivers did significantly better on identifying new routes. This result suggests that the taxi drivers' mastery can be _____________ to new and unknown areas. Their years of training and learning through deliberate practice prepare them to take on similar challenges even in places they do not know well or at all.
