Research in cognitive psychology suggests that crystallized intelligence, which involves skills such as vocabulary that are based on accumulated knowledge, tends to improve or remain stable with age. In contrast, fluid intelligence, which involves the ability to think quickly and flexibly, as well as solve new problems without relying on previous knowledge (skills used in tasks like the picture design test), tends to decline with age.
