Hard Unit 6: Developmental Psychology Adulthood And Aging

In examining the effects of aging on cognitive decline, various studies have explored different types of intelligence as they relate to adulthood. A well-regarded theory by Cattell distinguishes between two types of intelligence: fluid intelligence and crystallized intelligence. As individuals age, how do these two forms of intelligence typically change, and what implications does this have for learning and functioning in daily life?

Both fluid and crystallized intelligence significantly decrease with age.

Crystallized intelligence decreases but fluid intelligence increases with age.
