“…Note also that the 13 named individuals not only are extreme in terms of career peaks, but also in terms of the relation of these peaks to their goals and approaches to music composition, which Galenson's typology details quite nicely, in contrast to other models that do not articulate predictions relating individual differences in the creative process to career peak age. Moreover, in terms of making categorical classifications, numerous issues arise that are beyond the scope of this article: for instance, short-lived composers present inherent classification difficulties since their careers did not have much time to unfold (seeAccominotti, 2009), and some other composers (e.g., Beethoven or Debussy) appear to mix characteristics of Galenson's two types (seeKozbelt, 2008c). Indeed, many basic issues surrounding the finder-seeker typology remain unresolved, including the nature of the distribution of age at best work (bell-shaped versus bimodal-see, e.g.,Accominotti, 2009), the dimensional structure of Galenson's typology (mutually exclusive categories, a uni-dimensional tradeoff, or multi-dimensionalseeDurmysheva & Kozbelt, 2010), and the reliability of classification of individuals into the typology (seeGinsburgh & Weyers, 2006; for a more general discussion, seeKozbelt, 2008a).…”
