The psychology of expertise. Besides the book by Chi, Glaser, and Farr (1988), see the works by Ericsson (e.g., Ericsson, 1996; Ericsson & Charness, 1994, 1997; Ericsson & Smith, 1991b); Feltovich, Ford, and Hoffman (1997); Hoffman (1992); Hoffman, Shadbolt, Burton, and Klein (1995); and Wright and Bolger (1992).
