Which cognitive function involves holding information in mind for brief periods to support reasoning?

• A. Long-term memory
• B. Working memory
• C. Procedural memory
• D. Sensory memory

Answer: (B)

Holding information in mind for brief periods to support reasoning is what working memory does. It acts as a mental workspace where you actively maintain and manipulate information needed for current tasks—like keeping intermediate numbers in a problem, tracking steps in a plan, or holding a phone number while deciding what to do next. This is different from long-term memory, which stores knowledge and experiences over extended periods; sensory memory, which is an extremely brief echo of sensory input; and procedural memory, which is memory for how to perform skills and actions. The key idea is that working memory is all about keeping and transforming information just long enough to reason through a task, typically for seconds to a short period, making it the most fitting description for this item.
