Which of the following would be considered an internal memory strategy?

• A. Setting alarms on a phone
• B. Posting notes on a board
• C. Mental rehearsal
• D. Using a calendar

Answer: (C)

Internal memory strategies are mental techniques you use without external tools. Mental rehearsal involves silently repeating or practicing information in your mind, or picturing the steps of a task as you go through them. This strengthens encoding and retrieval by actively processing the material within your own cognitive system, making it more likely you’ll recall it later.

The other options rely on something outside your memory to prompt or store information—alarms on a phone, notes posted on a board, and using a calendar. These are external memory aids that cue you or hold information externally rather than relying on your internal thinking processes.
