Improving Memory
Memory experts believe that people can increase their ability to remember. One of the most important means of improving memory is the use of mental aids called mnemonic devices. Mnemonic devices include rhymes, clues, mental pictures, and other methods. One of the simplest ways is to put the information into a rhyme. Many people remember the number of days in each month by using a verse that begins, “Thirty days has September …”. Another method provides clues by means of an acronym, a word formed from the first letters of other words. For example, the acronym, HOMES could help a person remember the names of the Great Lakes – Huron, Ontario, Michigan, Erie, Superior. A good way to ensure remembering a piece of information is to study it long after you think you know it perfectly. This process is called overlearning. The more thoroughly you learn something, the more lasting the memory will be.
