Among late-life cognitive changes, which ability is most likely to stay the same or improve?

• A. Memory for names and places
• B. Processing speed
• C. Vocabulary
• D. Spatial abilities

Answer: (C)

Late-life cognitive patterns show a distinction between crystallized and fluid abilities. Vocabulary is a crystallized skill—built from years of reading, conversation, and accumulated knowledge—so it tends to stay stable and can even improve as people continue to learn. In contrast, memory for names and places taps episodic memory and typically declines with age; processing speed decreases as neural efficiency slows; spatial abilities also often wane with aging. Because vocabulary relies on stored knowledge rather than on rapid processing or novel problem solving, it is the ability most likely to remain the same or improve in later life.
