AP PSYCHOLOGY

Detailed explanation-1: -Fluid intelligence refers to abilities needed for abstract reasoning and speeded performance whereas crystallized intelligence refers to knowledge acquired through one’s culture including verbal ability and social knowledge (Schaie 1996).

Detailed explanation-2: -Fluid intelligence is where a person is able to think abstractly and solve problems using their own judgment and logic. Fluid intelligence refers to being able to critically think without being influenced by prior education or experience. This type of intelligence is generally used when learning new things.

Detailed explanation-3: -Fluid intelligence peaks at around age 20 and then gradually declines. This decline may be related to local atrophy of the brain in the right cerebellum, a lack of practice, or the result of age-related changes in the brain.

Detailed explanation-4: -Fluid intelligence decreases with age and crystallized intelligence remains stable or continues to increase with age. You can increase both types of intelligence.

Detailed explanation-5: -Cognitive aging is a complex phenomenon, which comprises various cognitive skills, broadly categorized into fluid and crystallized intelligence. Crystallized intelligence (gc) tends to be maintained, as opposed to fluid intelligence (gf), which tends to decline rapidly with age.
