Quizplus · Accepted Answer

The SB5 and WAIS-IV assess components of both crystallized and fluid intelligences, which are two types of intelligence that are thought to have different developmental trajectories. Crystallized intelligence involves knowledge and skills that are acquired through experience and education and tends to remain stable or increase with age, while fluid intelligence involves abstract reasoning abilities and tends to decline with age. Therefore, the fact that overall age-related losses tend to be small for most healthy, well-educated individuals can be attributed to their relatively preserved crystallized intelligence.
