| Annotation | In a sample of 263 male GO players (age range 18-78) at 48 levels of expertise, it was found that factors of expertise deductive reasoning (EDR) and expertise working memory (EWM) were independent of factors of fluid reasoning (Gf) and short-term working memory (STWM) that, along with cognitive speed (Gs), had been found to characterise decline of intelligence in adulthood. The main effects of analyses of cross-sectional age differences indicated age-related decline in EDR and EWM as well as in Gf, STWM, and Gs. However, interaction and partialling analyses indicated that decline in EDR and EWM decreased to no decline with increase in level of expertise. With increase in factors known to raise the level of expertise - particularly, intensive, well-designed practice - there may be no age-related decline in the intelligence that is measured in the abilities of expertise.
