Intelligence and expertise

This chapter stipulates two broad components of intelligence; General Fluid Intelligence (Gf), which is associated with abstract reasoning and short-term memory, and General Crystallized Intelligence (Gc), which is associated with knowledge and skills. For some kinds of expertise, the domain of knowledge or procedural skill to be acquired is relatively fixed and finite. One of the interesting aspects of expertise that provides an additional basis for aligning it closer to Gc than to Gf is the pattern of growth and decline of expertise that occurs during middle age and older adulthood. Determining the relationship between intelligence and tacit knowledge expertise is more of a challenge than it is for declarative and procedural knowledge. Higher levels of intellectual abilities appear to give the learner a head start or an overall advantage in the acquisition of expertise over learners with lower levels of intelligence.
