Next time you're in a meeting, try drawing a crude map of the room. Lay out the table and note where each person is sitting, and maybe a characteristic that will help you remember them. Dustin/Glasses, Gideon/Loves Star Wars, etc. This can help with name recollection. To take it a step further, you can number everyone and use that in notes to both help with shorthand and to create a visual to go with the notes that can also improve recollection. It also forces you to write down names, and research has shown that writing things down improves recollection. Lifehacker has more on what name maps looks like.
There are gads more techniques out there, but the new research is fascinating, in part, because the experiment itself provides a practical technique worth trying that, in many ways, echoes the association cues that are seen in other techniques.
