Question 3

Crystallized intelligence is assumed to increase throughout a person's life span.

Crystallized intelligence refers to the knowledge and skills that a person accumulates over their lifetime, which typically increases with age as individuals gain more experience and education.

A) Crystallized intelligence

This option is correct as crystallized intelligence is known to increase throughout a person's life. It encompasses the ability to use learned knowledge and experience, which tends to grow as individuals age and gain more exposure to various learning opportunities.

B) Fluid intelligence

Fluid intelligence is the capacity to solve new problems and think abstractly, which is generally believed to peak in early adulthood and may decline with age. Therefore, this option is incorrect as it does not increase throughout a person's life span.

C) Visual integration

Visual integration pertains to the ability to combine visual information, which does not necessarily correlate with age-related increases in cognitive abilities. This aspect of cognition may remain stable or even decline with age, making this option incorrect.

D) Iconic memory

Iconic memory refers to the short-term retention of visual information. This type of memory does not improve with age and is often subject to decline, particularly in older adults, thus rendering this option incorrect.

E) Working memory

Working memory involves the temporary storage and manipulation of information. Research suggests that working memory capacity tends to decline with age, making this option incorrect as well.

Conclusion

Crystallized intelligence is the only aspect listed that reliably increases with age, as it builds on a lifetime of experiences and knowledge. In contrast, fluid intelligence, visual integration, iconic memory, and working memory either decline or do not show consistent improvement throughout a person's life span, highlighting the unique nature of crystallized intelligence in cognitive development.
