Answer
Fluid and crystallized intelligence (Gf and Gc) are constructs that Cattell developed to describe human cognitive abilities. Gf involves the ability to think abstractly, reason, and solve novel problems, while Gc represents accumulated knowledge and skills. Cattell's research on lifespan changes in intelligence suggests that Gf peaks in early adulthood and gradually declines with age, while Gc continues to develop throughout life with increasing knowledge and experience.
