Key findings
- deliberate practice acquisition — Abstract Traditionally, professional expertise has been judged by length of experience, reputation, and perceived mastery of knowledge and skill.
- overview — Unfortunately, recent research demonstrates only a weak relationship between these indicators of expertise and actual, observed performance.
- expert performance — In fact, observed performance does not necessarily correlate with greater professional experience.
- abstract traditionally professional — Expert performance can, however, be traced to active engagement in deliberate practice (DP), where training (often designed and arranged by their teachers and coaches) is focused on improving particular tasks.
Limits
Deliberate practice synthesis — expert-performance literature; 10,000-hour slogans oversimplify — domain and coaching quality matter.
