你流的汗，出賣了你的小九九
信息素是一種化學信號，通常與吸引力有關，除了信息素之外，我們還會釋放許多其他的化學信號，它們可能傳達著驚慌、敵意或其他的情緒。
以恐懼為例，如果汗液中含有與恐懼相關的化合物，那麼在聞到一個受到驚嚇的人的汗液後，我們是否也會感到恐懼呢?
為了找到答案，研究人員讓男性受試者觀看了兩部電影：一部令人害怕，另一部讓人噁心。隨後，研究人員將受試者的汗液收集起來拿給女性受試者聞了聞，同時記錄下她們的面部表情。聞到「恐懼汗液」的女性會做出害怕的面部表情；而那些聞到「噁心汗液」的人則會做出厭惡的表情。由此得出的推論是，這些化合物促使女性受試者……[查看全文]
We Are What We Smell
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, aggression or other emotions.
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 inference is that the chemical compounds impelled the female subjects ...[full transcript]
