Which memory strategy works best for short-term memory?

The strategy that works best for short-term memory is rehearsal. Rehearsal involves the active repetition of information to keep it in short-term memory for a longer period. This technique can help in retaining the information temporarily, making it easier to recall in situations where immediate retrieval is required. For example, when trying to remember a phone number only long enough to dial it, repeatedly stating the number can effectively keep it fresh in one's mind.

Chunking, while a useful strategy, is more effective in organizing larger amounts of information into smaller, manageable units, thus aiding long-term memory rather than purely short-term retention. Elaboration, which involves making connections between new information and existing knowledge, is also beneficial but typically supports long-term memory encoding rather than focusing on short-term retention. Mnemonics provide an aid for memorization but often cater to more complex, long-term learning tasks rather than quick short-term recall.
