Which of the following is NOT a characteristic of crystallized intelligence?

Crystallized intelligence encompasses knowledge, skills, and abilities acquired through experience and education, and it tends to remain stable or even improve as one ages. This form of intelligence involves the application of learned knowledge, including skills like reading comprehension and vocabulary, which typically build up over a lifetime of learning and experience.

The notion that crystallized intelligence declines with age is inaccurate. In fact, many studies indicate that crystallized intelligence often remains consistent or can enhance as individuals accumulate more knowledge and experiences over time. Therefore, the option asserting that it declines with age is not a characteristic of crystallized intelligence, making it the correct choice for what does not fit the definition.

The other options correctly describe characteristics of crystallized intelligence, emphasizing its stable nature and its reliance on accumulated knowledge.
