CogSci holds that smell is the sense that has the most strong/immediate capability to trigger memories. It is discussed, in awe. We see anecdotes such as the sudden striking memory of sitting in your grandmothers kitchen when you were 6 - because you have just smelled the same scent of the food she cooked (30 years later). However, has anyone been using scent timed with instruction to improve performance? Are there any research experiments that you are aware of that show that a control group (no smells) performed less well than an experimental group (had smells during learning and testing)? I am only seeing (in the research literature) studies of the effect of certain smells (peppermint, cinnamon, etc) on the neural activity of lab rats being watched with fMRI. Please share if you are aware of human trial related to smell and learning/performance. Thank you.
