Which statement about aging and memory is most accurate?

• A. Episodic memory tends to decline with age, while semantic memory remains relatively stable
• B. All memory types decline at the same rate
• C. Working memory improves with age
• D. Long-term memory disappears in late adulthood

Answer: (A)

Understanding how aging affects different memory systems helps explain why this statement is most accurate. Episodic memory is the ability to remember personal experiences and specific events with their context (what happened, where, and when). This type tends to show noticeable decline with aging, especially for recent events and when trying to recall details after a delay. Semantic memory, on the other hand, is general knowledge—facts, meanings, vocabulary, and world knowledge. It is more resistant to aging and often remains stable across much of later life, sometimes even improving as a result of lifelong learning and experience. So, as people age, the memory system tied to personal experiences becomes less reliable, while the system that stores general knowledge stays comparatively intact. This contrast makes the statement about episodic memory declining and semantic memory remaining stable the most accurate reflection of aging and memory. Statements claiming that all memory types decline at the same rate aren’t supported by typical aging patterns, since semantic memory stays relatively steady. Claims that working memory improves with age conflict with evidence showing it usually declines or remains challenging to sustain with age. And saying long-term memory disappears in late adulthood ignores the substantial preservation of many long-term memories, especially for well-established facts and skills, even if some retrieval can become harder.
