How does working memory relate to short-term memory?

• A. They are the same system, involving conscious processing.
• B. Working memory stores information permanently.
• C. It processes only visual information.
• D. It does not involve retrieval from long-term memory.

Answer: (A)

Working memory is an active, dynamic system for holding and manipulating information in the moment. Short-term memory, by contrast, is the brief storage component that keeps items accessible for a short time. In the standard view, working memory isn’t just a storage space—it includes processes that control and manipulate information, such as the central executive and specialized subsystems like the phonological loop for verbal info and the visuospatial sketchpad for imagery, with an episodic buffer that can integrate information across sources. Importantly, working memory draws on information from long-term memory when needed and can update what it’s holding as tasks demand.

So they’re not the same thing. Short-term memory provides the temporary store, while working memory adds the processing and control needed to use that information. The option that treats them as the same system misses the active, processing role of working memory. The other choices misstate key features as well (permanent storage, exclusive to visual info, or lack of long-term memory retrieval).
