Final answer:
Crystallized intelligence refers to acquired knowledge and the ability to retrieve it, unlike fluid intelligence which deals with solving complex problems and tends to decline with age.
Step-by-step explanation:
The term that refers to the cumulative effect of culture and learning on task performance, which is measured by tests of verbal ability and cultural knowledge and does not decline with age is crystallized intelligence. Crystallized intelligence pertains to the acquired knowledge and the ability to retrieve that knowledge. It is used in activities such as mastering coursework and solving concrete, straightforward problems. On the other hand, fluid intelligence is associated with the ability to see complex relationships and solve problems, and it tends to decline in late adulthood.
