Deniz, Ericsson and Charness' research on expert skill development is a must read for anyone with aspirations to play at a high level. Basically the conclusion is that everyone has to spend a fairly standardized time and mental energy to get there. And that expert skill mastery is a cross-disciplinary state. Here is a teaser: "When experts exhibit their superior performance in public their behavior looks so effortless and natural that we are tempted to attribute it to special talents. Although a certain amount of knowledge and training seems necessary, the role of acquired skill for the highest levels of achievement has traditionally been minimized. However, when scientists began measuring the experts' supposedly superior powers of speed, memory and intelligence with psychometric tests, no general superiority was found --the demonstrated superiority was domain specific." [so maybe Grisha's NOT smarter than me? he seems to be, maybe it's just an act!] "For example, the critical difference between expert musicians differing in the level of attained solo performance concerned the amounts of time they had spent in solitary practice during their music development, which totaled around 10,000 hours by age 20 for the best experts, around 5,000 hours for the least accomplished expert musicians and only 2,000 hours for serious amateur pianists. More generally, the accumulated amount of deliberate practice is closely related to the attained level of performance of many types of experts, such as musicians (Ericsson et al., 1993; Sloboda, et al., 1996), chessplayers (Charness, Krampe & Mayr, 1996) and athletes (Starkes et al., 1996)." For the best experts: 10,000 / 365 / 4 = 6.85 years with 4 hours of deliberate practice a day 13.7 years with 2 hours For the least accomplished experts: =3.4 years with 4 hours a day 6.8 years with 2 hours a day
