A. My recent study on sleep, in which we found that we can not smell while asleep surprised me the most. We found that, in fact, we do ”wake up and smell the coffee” rather than smell the coffee and then wake up. This finding is also extremely important because of the implications regarding house fires and the necessity of having auditory smoke alarms. The reason I was so surprised by this finding is because, like most of us, I had simply assumed that we could smell while sleeping.
A. I help fragrance and flavor companies understand where our scent preferences come from, how they can be changed and how emotion and memory can be manipulated by scent to increase product appeal and loyalty. I also help them understand how language can influence scent perception and how to most effectively utilize this force.
A. Yes, I have become more attuned to scents over the years. When I began my dissertation research and started working with a large collection of scents, preparing them, making dilutions, testing them and learning their names I discovered I was exponentially increasing my scent vocabulary and doing so made me appreciate and able to recognize many smells that I hadn’t even noticed before. Everyone can increase their olfactory ability by simply paying attention to scents.
I am a “supertaster,” but that is due to genetics. Supertasting does not appear to be anything that you can train someone to be. However, some genetic, hard-wired responses to odors do respond to training or exposure. People with a specific anosmia to androstenone, a steroidal musk compound, can become androstenone smellers if they are repeatedly exposed to it. This was serendipitously discovered by Chuck Wysocki at the Monell Center when he had his anosmic subjects come back to the lab frequently for follow up tests, and over time observed that they became “cured” of their androstenone blindness.
A. Almost all the women I approached were happy to participate in the study. They were very eager to share their scent predilections with me, even personal and intimate details. Of the 113 women in the study, all but two knew that scent was very important to their lives — not just intuitively, they were able to be very explicit about it. Though many of them confessed that they had never before thought about fragrance and psychology in the way I was asking them to. Their stories were as much a revelation to many of them as they were to me.

A. I have always been a “sensual” person and literally take time to smell the roses. I have also always been scientifically interested in the interaction between psychology and biology and studying scent is the perfect way to do this. I believe scent is also the Rosetta stone for understanding emotion, another topic which fascinates me.
A. I was too young to appreciate most of the scent differences between the countries that I lived in, because I was only 7 when we made our final move to Canada, but I do remember Paris to be particularly scent-ful and pleasantly so. One of the scents that can transport me back in time and space, but which unfortunately requires fate for me to stumble upon, is a concatenation of baking butter, coffee and a tinge of cigarette smoke and car exhaust, in a particular combination it elicits a strange and wistful nostalgic feeling and always brings me back to Paris.
A. Yes in terms of fine fragrances. My first favorite perfume which I wore for about 4 years was Anais Anais, my next was Alfred Sung. I chose these two fragrances because friends of mine were wearing them and I liked how they smelled. I wore Alfred Sung for a long time and then in my early 30’s I switched to Neiges by Lise Watier. One of my reason for choosing this scent was because it was made by a Canadian designer so no one in the US, where I was living, would smell like me. I wanted to make my fragrance mark.
I used to be a one perfume loyalist no matter what the situation. More recently, I have started to alternate between three fragrances: Neiges, Michael by Michael Kors and She by Giorgio Armani. I tend to wear these different perfumes for different occasions or for how I want to feel at certain times. My behavior conforms exactly to what I found in the study I did for Oprah Magazine. Women in their 20s are the most conformist and want to smell like their friends and are also the most susceptible to fragrance fashion, while women in their 40s are most “self-centered” and use perfume mainly for themselves and for specific occasions.
A. Actually, my husband’s scent did figure prominently in my attraction to him and still does. When I met him – and found his scent attractive – I wasn’t on the pill, which is good except we don’t plan to have children. There is research showing that women’s scent preferences for men change depending on whether or not they are on the pill, and that not being on the pill is best for picking biologically suitable mates. Shortly after we began dating I did go on the pill and the appeal of his scent remained, probably because of the positive associations I had acquired to his scent. I have met a number of women who have told me that they knew they would marry as soon as they smelled their husband’s scent.
A. Humans have traditionally been characterized as quite low on the animal totem pole for scent sensitivity. However, researchers have proven that we are actually quite good at detecting scent, though we are still less keen than other mammals (with dogs being the very best). Most mammals use scent as the principal sense through which they understand and explore their world. The presumption that smell is of little importance to us and our world, however, is much more cultural than physical. The Ongee, a hunting and gathering people of Little Andaman Island in the Bay of Bengal use scent as the primary sensory medium through which the categories of time, space and individuals are conceptualized. As we Westerners come to understand our sense of smell more and its essential involvement in our lives we, like the Ongee, will be able to use scent to better understand our world.
A. I am continuing to do research on many of the topics that I cover in my book. Currently I am particularly intrigued by both commercial and scientific pursuits into the possibilities of a smellable aphrodisiac, and my next book may be about the hunt for lust in a bottle. I am also interested in writing about the psychology and biology of emotion and the tug of war between passion and reason in humans.
A. Yes, two of them immediately come to mind. One is the smell of the perfume my mother wore during the time we lived in Paris, when I was 4 or 5, called Crepe de Chine. Unfortunately this perfume is no longer available, though I have tried to hunt it down and even contacted the perfume archives at Versailles. I could have gotten a bottle through the Versailles collection but it would have been an ordeal. Fortunately my mother had kept an old bottle that I now have at home and I go to it from time to time to conjure a special scent memory.
The other Proustian scent I remember vividly is the cologne worn by my first boyfriend who came from Chile — his fragrance was Nino Cerruti. Although the last time I smelled it on him was almost 25 yrs ago I use this scent now as a memory test and every few years I sniff the empty bottle that I’ve kept at my parent’s house to see if I can conjure the memory of those early days. It still works.
Whenever I go to these fragrance bottles and uncork the genie inside, I always feel infused with a wonderful, powerful happiness. My emotions are at least partly due to the fact that I am still amazed at how smell, like none of my other senses, can transport me to a different time and place.
