Question 3 of 6 View Policies Current Attempt in Progress A famous study titled "The Effect of Deliberationtice in the Acquisition of Expert Performance," published in Psychological Review (Ericsson, Krampe, and Tesch-Romer, 1993) led to the now-conventional wisdom that 10,000 hours of deliberate practice are necessary to achieve expert performance in skills such as music and sports. The researchers in this study asked violin students at the Music Academy of West Berlin to keep a diary indicating how they spent their time. The researchers also asked the students' professors to indicate which were the top students with the potential for careers as international soloists, which were good violinists but not among the best, and which were studying to become music teachers. Researchers found that those in the top two groups devoted much more time per week to individual practice than did those in the group studying to become music teachers. is the quantitative variable in this study. eTextbook and Media is the categorical variable in this study. eTextbook and Media Save for Later Attempts: 0 of 3 used Submit
