What strategy involves simply repeating information to keep it in short-term memory?

The strategy that involves repeating information to keep it in short-term memory is maintenance rehearsal. This cognitive technique focuses on keeping information active within the short-term memory store by repeating it over and over again. For example, if you are trying to remember a phone number, you might repeat the digits to yourself several times to keep them fresh in your mind.

Maintenance rehearsal is particularly effective for memorizing simple and transient information. The act of repetition helps to maintain the information in the short-term memory, but it does not necessarily lead to long-term retention unless the information is encoded through more complex strategies.

Other strategies mentioned operate differently. Elaborative rehearsal involves connecting new information with existing knowledge, promoting deeper understanding and stronger long-term retention. Chunking is a method of grouping information into larger, manageable units to enhance memory capacity, and the method of loci uses a visual-spatial technique to aid in memory recall. Each of these methods serves particular purposes in memory retention but does not focus solely on the straightforward repetition characteristic of maintenance rehearsal.
