The details about this sort of practice are drawn from a relatively new area of psychology that can be best described as “the science of expertise.” This new field seeks to understand the abilities of “expert performers,” that is, people who are among the best in the world at what they do, who have reached the very peak of performance, and I have published several academic books on the topic, including Toward a General Theory of Expertise: Prospects and Limits in 1991, The Road to Excellence in 1996, and The Cambridge Handbook of Expertise and Expert Performance in 2006.
