Detailed explanation-1: -Fluid intelligence-our ability to reason speedily and abstractly, as when solving novel logic problems-decreases beginning in the twenties and thirties, slowly up to age 75 or so, then more rapidly, especially after age 85 (Cattell, 1963; Horn, 1982; Salthouse, 2009).
Detailed explanation-2: -Background: Fluid intelligence declines with advancing age, starting in early adulthood. Within-subject declines in fluid intelligence are highly correlated with contemporaneous declines in the ability to live and function independently.
Detailed explanation-3: -These findings suggest that the age-related decline in fluid intelligence is due to general slowing and frontal decline, as well as other unidentified factors.
Detailed explanation-4: -Fluid intelligence is the capacity to think speedily and reason flexibly in order to solve new problems without relying on past experience and accumulated knowledge.
Detailed explanation-5: -Cattell and Horn thought that both types of intelligence increased throughout childhood and adolescence. However, while crystallized intelligence would continue to make gains through adulthood, fluid intelligence would peak in the early 20s and then start to decline between ages 30 and 40.
