I Smell Your Fear

The most primitive of our senses is olfactory–the sense of smell. It is also the most emotionally powerful. Once we have smelled something it is filed in our brains forever, and if we ever encounter the odor again, it is almost instantly recalled. Often with memories of that first encounter. A certain food, perfume, chemical, you name it, can pull us back in time more deeply than can any sight or sound.

But can you smell another’s emotion? Can you detect fear, or anger, or disgust with your nose? Animals can. If one dog or gazelle or wildebeest in a group senses fear, the other members of the group immediately sense the same danger. Herd mentality. Some of this might be transmitted through body language or certain movements, even facial expressions, but pheromones released by the concerned group member play a big role. So why shouldn’t we humans have the same ability?

Apparently, we do.

If the results of a recent study done by Gün Semin and colleagues from Utrecht University and published in Psychological Science can be believed, humans possess the ability to communicate emotions through chemical signals. This is an interesting study that used sweat to analyze these chemical transmitters.
