Toward a general theory of expertise: Prospects and limits

During the last twenty years our understanding of expertise has dramatically increased. Laboratory analyses of chess masters, experts in physics and medicine, musicians, athletes, writers, and performance artists have included careful examination of the cognitive process mediating outstanding performance in very diverse areas of expertise. These analyses have shown that expert performance is primarily a reflection of acquired skill resulting from the accumulation of domain-specific knowledge and methods during many years of training and practice. The importance of domain-specific knowledge has led researchers on expertise to focus on characteristics of expertise in specific domains. (from the book); In “Toward a General Theory of Expertise” many of the world's foremost scientists review the state-of-the-art knowledge about expertise in different domains, with the goal of identifying characteristics of expert performance that are generalizable across many different areas of expertise. These essays provide a comprehensive summary of general methods for studying expertise and of current knowledge about expertise in chess, physics, medicine, sports and performance arts, music, writing, and decision making. Most important, the essays reveal the existence of many general characteristics of expertise. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
