Which method is commonly used to enhance memory retention?

Enhancing memory retention is a multifaceted process, and all the methods mentioned—repetition, association, and visualization—play significant roles.

Repetition involves actively reviewing information multiple times, reinforcing neural pathways, and making it easier to retrieve that information later. This method is rooted in the idea that the more frequently something is encountered, the more likely it is to be remembered.

Association connects new information to existing knowledge or experiences, thereby creating a mental link that aids in recall. By building on what is already known, learners can improve understanding and retention of new concepts.

Visualization involves creating mental images, diagrams, or other visual aids to represent information. This technique taps into the brain's ability to remember images more effectively than text, making it easier to recall details associated with those images.

Since all these strategies contribute to improving memory retention in distinct and complementary ways, the most comprehensive answer is that all of the methods listed are effective in enhancing memory retention.
