Praxis 5857 Practice Question
Which of the following cognitive abilities is most affected by the aging process?
Correct Answer: C
Rationale: Fluid intelligence, which involves problem-solving and the ability to think abstractly, tends to decline with age due to changes in processing speed and cognitive flexibility. In contrast, working memory (A) can be affected but often shows variability among individuals. Implicit memory (B), related to skills and habits, remains relatively stable throughout life. Attention span (D) may fluctuate, but it does not consistently decline like fluid intelligence. Understanding these distinctions highlights how cognitive aging impacts various abilities differently.
