Question

Match the item with the correct description.

1. Fluid intelligence
2. Crystallized intelligence
a. Increases with age
b. Begins to decline around age 30
c. Increases around age 45

Answer 1

Fluid intelligence refers to the ability to see complex relationships and solve problems, while crystallized intelligence refers to acquired knowledge. Fluid intelligence declines around age 30, while crystallized intelligence tends to hold steady or improve as we age.

Step-by-step explanation:

In the context of intelligence, fluid intelligence refers to the ability to see complex relationships and solve problems, while crystallized intelligence refers to acquired knowledge and the ability to retrieve it.

Fluid intelligence decreases with age, beginning to decline around age 30. On the other hand, crystallized intelligence tends to hold steady as we age, and may even improve. For example, adults show relatively stable to increasing scores on intelligence tests until their mid-30s to mid-50s.
