Crystallized intelligence, as described in Cattell's theory, refers to knowledge and skills accumulated through life experiences, education, and cultural exposure. Examples include vocabulary, general knowledge, and problem-solving based on prior learning. In contrast, fluid intelligence involves the ability to think abstractly, reason, and solve new problems without relying on prior knowledge.
