External memory is memory that uses cues from the environment to aid remembrance of ideas and sensations. When a person uses something beside his/her own internal memory tricks, traits, or talents to help him/her remember certain events, facts, or even things to do, the person is using an external memory aid. External memory aids are used every day. A large part of these aids come from technology; people use their smartphones to remind them when they have meetings and Facebook reminds people of their friends' birthdays. These aids also include taking notes in class, carrying a grocery list to the supermarket, or jotting down dates on a planner. Even people, or prompters, can be used as external memory aids.
