Verified content
- [full text] Preregistered (OSF), results-blind accepted replication of Ericsson et al. 1993 with 39 violinists in three skill groups, double-blind interviews.
- [full text] Accumulated practice alone by age 18 explained 26% of the variance in group (η² = 0.26, 95% CI 0.03–0.44), vs 48% in the original; teacher-designed practice 23% (95% CI 0.02–0.41).
- [full text] Best violinists (M = 8,224 hours) had not accumulated significantly more practice than good violinists (M = 9,844), p = 0.364.
Limits
- [assessment] 39 violinists, one domain, retrospective practice estimates.
