Relationship Between Fluid and Crystallized Intelligence

Medium Unit 11: Testing & Individual Differences Assessing Intelligence

In the realm of intelligence testing, one widely debated theory is the distinction between 'fluid' and 'crystallized' intelligence. Fluid intelligence is often described as the capacity to reason and solve new problems independent of previously acquired knowledge. In contrast, crystallized intelligence refers to the ability to use learned knowledge and experience. According to studies, individuals tend to perform differently on tasks designed to assess these two types of intelligence as they age.

Based on this understanding, which of the following statements best captures the relationship between fluid and crystallized intelligence?

Fluid intelligence decreases with age, while crystallized intelligence remains stable or may even increase.

Fluid intelligence is unrelated to crystallized intelligence.

Both fluid and crystallized intelligence consistently increase throughout a person's lifespan.

Crystallized intelligence decreases more rapidly than fluid intelligence as one ages.

Fluid intelligence increases significantly with education, while crystallized intelligence is fixed.
