On the subject of state-dependent learning, in other words, being in the same emotional/physical state to recall information as you were when you learned it….
Some experiments with rose scent at the University of Lübeck in Germany, showed that people were better at remembering information when smelling the same smell they’d experienced when learning it and in this case – the scent of rose.
Peppermint oil is meant to encourage concentration and alertness. How about trying your own experiment? Sniff it while revising and sniff it when trying to recall the information and see for yourself.
You can get essential oil of peppermint from health food stores, chemists and the larger supermarkets. Don’t get it on your skin though – it’ll burn. And it goes without saying, keep it away from your eyes or the kids.
Those of you who are thinking of shoving Polo mints up your nose… well… let us know how you get on!
