Question

Gary is not fast when completing a vocabulary test but if given enough time can get nearly 100% on the test. while gary's old age may influence his reaction time, his _______ intelligence is fully intact due to his large amount of life experience and knowledge.

Answer 1

This is a question of fluid intelligence versus crystallized intelligence.
Fluid intelligence is the ability to reason and solve novel problems. It reduces with age. On the other hand, crystallized intelligence is the ability to use experience, skills and knowledge to solve problems. It increases with age.

In the current scenario, Gary's crystallized experience is fully intact given his age, experience and knowledge.
