They then tested these volunteers in a room infused with either rosemary essential oil, lavender essential oil or no aroma. Participants were told they were there to test a vitamin water drink. Any comments about the aromas were passed off as irrelevant and "left over from the previous group to use the room".
The volunteers and I then took a test which was designed to test their prospective memory. It's a clever test with many layers so you never quite know what's being tested. At the start, objects are hidden around the room in places which you have to remember at the end of the test.
Then you perform a series of distracting but fun word puzzles while increasingly complex demands are made of your memory by the testers in my case two extraordinarily nice and competent graduate students, Kamila and Lauren. My marks were squarely average. I didn't remember to remind Kamila to get her car from the garage in much the same way that I would have forgotten myself. What Mark's team found was remarkable.
The volunteers in the room with the rosemary infusion did statistically significantly better than those in the control room but lavender caused a significant decrease in performance.
