Creative Development as Acquired Expertise: Theoretical Issues and an Empirical Test

Abstract

Although outstanding creativity has been viewed as an acquired expertise, creative development might operate differently than occurs in sports, games, and music performance. To test the creative-expertise hypothesis, the careers of 59 classical composers were examined according to the differential aesthetic success of their 911 operas. The potential predictors were seven measures of domain-relevant experience: cumulative years (since first operas, first compositions, and first lessons) and cumulative products (genre-specific operas, all operas, all vocal compositions, and all compositions). The nonmonotonic longitudinal trends and the relative explanatory power of the expertise-acquisition measures indicate that complex specialization (“overtraining”) and versatility (“cross-training”) effects may determine creative development across the life span. The broader implications of the findings are then discussed.
