Repeating someone's name several times shortly after being introduced to that person is an effective strategy for rehearsal.

Explanation:

"It is usually assumed that the short-term memory spontaneously decays over time, typically in the region of 10 – 15 seconds, but items may be retained for up to a minute, depending on the content. However, it can be extended by repetition or rehearsal (either by reading items out loud, or by mental simulation), so that the information re-enters the short-term store and is retained for a further period. When several elements (such as digits, words or pictures) are held in short-term memory simultaneously, they effectively compete with each other for recall."
