When does crystallized intelligence peak?

Question

Quizplus · Accepted Answer

Crystallized intelligence refers to acquired knowledge, skills, and abilities that have been accumulated over time. It is believed to peak in middle adulthood, around age 40-60. This is because adults in this age range have had more opportunities to accumulate knowledge and experience, and are better able to make use of that knowledge to solve problems and make decisions. After middle adulthood, there may be some decline in crystallized intelligence as aging begins to affect some cognitive abilities.
