Scientists at Philadelphia's Monell Chemical Senses Center take a look at how scents dictate behavior.
This effect of inducing others to drop everything and pay attention to me-me-me is apparently what we hope for with our own perfumes and colognes, at least to judge by the advertising. But scientists and perfumers seem to know remarkably little about which scent compounds — noxious or otherwise — produce particular effects, or why. We don’t seem to respond like those species in which a specific scent automatically elicits a fixed behavioral response, said Pamela Dalton, a scent researcher at the Monell Chemical Senses Center in Philadelphia.
Or at least we’re not aware if something like that is happening. A 2003 study at Monell found that scent samples from human males caused a neuroendocrine response in women, changing the length and timing of the menstrual cycle. Male scent also made the women less tense and more relaxed, at least when they didn’t know that what they were smelling was a man. (More predictably, a study this year reported that the scent of male, but not female, experimenters left lab rats feeling a stress level roughly equivalent to being restrained in a tube for 15 minutes.)
Ms. Dalton theorized that early perfumers might have adapted the sometimes unpleasant odors of other species as a way of taking on their power. Something like that certainly happens in the animal world.
