The Mnemonic Peg System is a memory aid that helps individuals remember information by associating it with a predetermined list of "pegs." Each peg is typically a number that corresponds to a specific word or image, creating a mental hook for recalling information. For example, the number one might be associated with the word "sun," while two could be linked to "shoe." To use the system, a person visualizes the information they want to remember as interacting with these peg words. This technique enhances memory retention by creating vivid mental images, making it easier to recall the information later.
