Maintenance rehearsal is a process related to short term memory that consists on verbalizing or thinking repeatedly about a piece of information. This way, the short term memory can hold the information for a little longer when we do this.
In this example, <u>Adela mentally repeated the number</u> while searching the shelves for the correct oil filter for her car. Adella was <u>thinking repeatedly about this specific piece of information so she wouldn't forget it. </u>
Thus, this is an example of using Maintenance rehearsal to keep the information in her short-term memory.
