Which memory is defined as the short-term storage of information and does not entail manipulation or organization of material?

• A. Procedural memory
• B. Echoic memory
• C. Long-term memory
• D. Short-term memory

Answer: (D)

Memory has different stores that differ in how long they hold information and what you do with it. Short-term memory is the temporary holding place for information you’ve just encountered, kept for a short period and not automatically manipulated or reorganized. It’s about storage, not transformation. If you start to work with the material—rehearsing, sorting, or solving a problem with it—that’s more about working memory, which involves actively manipulating information.

So the item’s description fits short-term memory because it emphasizes brief storage without the willful manipulation or restructuring of the material. For contrast, echoic memory is a brief sensory trace for auditory input, procedural memory is a long-term store for skills, and long-term memory refers to information held for extended periods and ready for retrieval.
