Oct 4 Acquisition of Expert Performance: what are the most common critiques of Ericsson's theory? - during our gradeschool years, we get about 5000 hours of deliberate practice during school - homework (if it's designed correctly) is also deliberate practice - basic skills have to do with notetaking and organizing and reorganizing information - deliberate practice for a researcher is reading an article 4 times over and over, zeroing in on teh method and results to see exactly how they did things - previous questions: Tiger became the best because of deliberate practice, and even if we continue to be involved with the domain, if we're not doing deliberate practice, then we likely won't get any better and in fact, we may slip - as they get older, what happens to experts? some peak at the age you'd expect, but some do not - why is Steve Nash still so good? - Ericsson acknowledges that the taller you are, the more likely you are to be a good basketball player, but this is not completely necessary - he used to give himself drills as a kid. he has a great work ethic. he comes up with a plan on how to improve and he executes it. he invents better ways of doing what is required of him. - what Nash is doing is pretty exceptional. - another study on the effects of expert performance in age-related declines in motor speed - brought in 20- and 50-year old pianists and gave them either a piano-related task or just a speed task. a 50-year old couldn't do the speed task as well as the 20-year old, but on the music-related task they were about the same - Ericsson uses Gardiner as a foil of someone who uses deliberate practice. Gardiner critiques this, "I have no hesitation in stating that students differ from one another in the skill and ease with which they can sight read, master, remember and interpret pieces" > the very first time he sees students, he can see differences between them. he suggests that these initial differences are reflective of their natural abilities - Ericsson believes that these initial differences are attributable to their pervious experiences. even the Suzuki method does not believe in innate talent, and this is the most successful method. - teachers were worried about K's daughter Sophie because she sucked at ball sports. this is because she had no exposure, no practice, no training stemming from a lack of interest. he promoted interest, and now she's better - do some people have physical advantages? not really, no. but in their domain, they might be better - you see Michael Phelps' figure (hourglass) and you go "well, he'd likely be a good swimmer," but really the figure probably happened because he swims. - after two or three years, your heart will grow larger as a result of deliberate practice
