Intelligence and expertise

This chapter discusses intelligence and expertise, beginning with definition of terms, followed by historical and current notions of crystallized intelligence, methods of study in individual differences in expertise, acquisition of expertise, expert short/long memory, to what degree fluid intellectual skills are a limiting factor, maintenance of expertise, and tacit knowledge expertise. The study of intelligence and expertise is a much more recent focus for researchers than is the study of, say, intelligence and academic performance. Nonetheless, based on research from experimental psychology that has focused on understanding the development and expression of expertise, and a small number of studies that have examined individual differences in expertise, a relatively consistent pattern of results has been found.
