Ed. K. Anders Ericsson, Neil Charness,(both of Florida State Univ.) and P.J. Feltovich, & R. R. Hoffman (both of Florida Institute for Human and Machine Cognition). 901 pages. Anthology of 42 scholarly articles on various aspects of expertise, divided into six sections: overview; methodology; acquisition/maintenance of expertise; research methods; domains of expertise (professions, arts/sports/motor skills, games) and generalizable mechanisms mediating expertise <--fascinating section) I read 18 of the essays. My favorites were: "The Influence of Experience and Deliberate Practice on the Development of Superior Expert Performance," by K. Anders Ericsson; "A Merging Theory of Expertise and Intelligence," by John Horn & Hiromi Masunaga; "Modes of Expertise in Creative Thinking: Evidence from Case Studies," by Robert Weisberg; "Professional Writing Expertise," by Robert T. Kellogg; "Educators and Expertise: A Brief History of Theories and Models," by R.J. Amirault & R. K Branson; and "Aging and Expertise," by Ralf Th.Krampe & Neil Charness. I also read about "Expertise in Medicine and Surgery," by Geoff Norman, Kevin Eva, Lee Brooks, & Stan Hamstra; "Expertise in Software Design," by Sabine Sonnentag, Cornelia Niessen, & Judith Volmer; "Social and Sociological Factors in the Development of Expertise," by Harold Mieg; "Decision-Making Expertise," by J. Frank Yates & Micheal D. Tschirhart; "The Making of a Dream Team: When Expert Teams do Best," by Eduardo Salas, Michael A. Rosen, et al; and other articles.
Overall, expertise is defined as 1)requiring usually ten+ years of "deliberate practice" (K. Anders Ericsson's term) to acquire; 2)being linked with increasingly depth and breadth of knowledge/skill in a specific domain; 3)improving with age (!),until some decline in one's 70s--as contrasted with non-expert learning/performance, which begins to decline in early adulthood; 4) requiring lifelong deliberate practice to maintain. There are both differences and similarities across domains of expertise, as one would expect.
