Step-by-step explanation:
Memory aids are techniques that help in improving memory and organizing information. They are techniques that use vivid imagery and organizational devices, as well as mnemonic devices. Mnemonic devices are memory aids that help us encode and recall information by creating associations or patterns.
For example, if you want to remember the order of the planets in the solar system, you can use a mnemonic device such as 'Mr. VEM J. SUN,' which stands for the names of the planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Memory aids can be useful in learning because they help to make information more memorable and easier to retrieve. By using visualization and organization techniques, mnemonic devices, and other strategies, memory aids enhance the encoding and retrieval processes, making it easier to remember and recall information.
