Abstract
Facing facts about deliberate practice.
Highlights
We credit Platz et al for their effort and thank them for their criticisms of our meta-analysis. None of these criticisms challenge our conclusion that deliberate practice is not as important as Ericsson and colleagues have argued
Platz et al.’s (2014) major criticism targets our conclusion that deliberate practice accounted for 30% of the variance in music performance
They write that “relationships between variables should be interpreted in terms of linear relationships” (p. 10), and that “it is incorrect to interpret our findings as evidence that DP explains 36% of the variance in attained music performance” (p. 11)
Summary
The influence of deliberate practice on musical achievement: a meta-analysis by Platz, F., Kopiez, R., Lehmann, A. Deliberate practice accounted for about one-third of the reliable variance in performance in each domain, leaving most of the variance explainable by other factors.
