Which statement best describes short-term memory versus working memory?

• A. Short-term memory is passive storage for about 15-30 seconds.
• B. Working memory is passive storage for about 15-30 seconds.
• C. Short-term memory stores information for an extended period in long-term storage.
• D. Working memory is a repository for long-term knowledge.

Answer: (A)

Short-term memory refers to a brief, passive holding area for information, lasting around 15 to 30 seconds. This contrasts with working memory, which is not just about storing information but actively manipulating it for ongoing tasks—like mental math, following instructions, or keeping a question in mind while you solve it. Because short-term memory is mainly about temporary storage with a short time window, describing it as passive storage for about 15–30 seconds best captures the distinction from working memory. The other statements misrepresent either the passive nature of the term, or the role of working memory, or confuse short-term storage with long-term knowledge.
