Ask if you didn’t get the other person’s name right when you first met.
Repeat the name aloud again. Terms are often better remembered this way.
To be on the safe side, you can write down the name on a piece of paper after the conversation – for many people, the visual representation of a name helps them to remember it.
Ask where the name comes from. Terms that are spoken about consciously stay in the memory longer. A pleasant side effect is that the person you are talking to notices your interest, which helps you to be remembered better.
Create mnemonic bridges: Link the name with the appearance of the other person or with people you know who have the same name.
