Which type of intelligence increases throughout the lifespan due to schooling and experiences?

Crystallized intelligence refers to the knowledge and skills that one acquires over time through experiences, education, and cultural exposure. It encompasses a wide range of abilities, including vocabulary, general knowledge, and the ability to utilize learned information in practical contexts. As individuals progress through their lives, they engage in various learning opportunities, whether through formal education or life experiences, leading to an increase in crystallized intelligence.

This type of intelligence tends to grow as people accumulate knowledge and practice skills, in contrast to fluid intelligence, which is associated more with the ability to solve novel problems and is often thought to decline with age. The distinction is essential because it highlights how lifelong learning and experiences can enhance cognitive capabilities, particularly in practical and social domains.
