We are what we smell

Feromons, there are those chemical signals that are often associated with attraction. 

---> Pheromones: they’re those chemical signals often associated with attraction.

But there are many chemical signals we give off including ones that might signal alarm, agression or other emotions.

---> But there are many chemical signals we give off—including ones that might signal alarm, aggression or other emotions.

For example, take fear, if sweat contains compounds associated with fear, could someone smelling the sweat of frightened person themselves mind out experience in fear?

---> For example, take fear. If sweat contains compounds associated with fear, could someone smelling the sweat of a frightened person themselves wind up experiencing fear?

To find out researchers had male subjects watch two movies. 

One was scary, and the other made viewers feel disgusted.

The researchers then collected the participants' sweat.

Female subjects then smelled the sweat while the scientists recorded their facial expressions.

And the women who smelled fear sweat actually produced fearful facial expressions, while those who smelled the disgust sweat made disgusted faces. 

The inferences that the chemical compounds impelled the female subjects to remotely experience the same emotions felt by the sweaty males.

---> The inference is that the chemical compounds impelled the female subjects to remotely experience the same emotions felt by the sweaty males. 

The study is in the journal Psychology Science.

Despite our lack of conscious of awareness of in the personal chemical communication, it seems that we nevertheless do physically and psychologically process such chemical signals.

---> So despite our lack of conscious awareness of interpersonal chemical communication, it seems that we nevertheless do physically and psychologically process such chemical signals.

The researchers note that the study provides evidence that the communication is not limited language or visual cues alone. Even we rational humans can become emotionally synchronized via set.

---> The researchers note that this study provides evidence that communication is not limited to language and visual cues: even we rational humans can become “emotionally synchronized” via scent.
