以前的研究已经证明了非语言交流中的性别差异。目前尚不清楚的是，通过化学信号（一种相对被忽视的非语言交流媒介）进行的嗅觉交流是否存在类似的性别差异。因为女性通常有更好的嗅觉和对情绪信号更敏感，我们假设，与男性参与者相比，相对于中性控制条件，女性参与者会模仿发出化学信号的发送者的恐惧状态。面部肌电图被用于一个双盲实验，以测量在接收器的状态发送者的部分再现，控制的调节影响的发送者和接收者的性别。结果表明，只有女性参与者模仿了发送者的恐惧状态。本研究揭示了一个边界条件，有效的化学信号通过报告的行为证据的性别不对称的嗅觉通信通过化学信号。
Previous research has documented sex differences in nonverbal communication. What has remained unknown is whether similar sex differences would exist with regard to olfactory communication via chemosignals, a relatively neglected nonverbal communication medium. Because women generally have a better sense of smell and greater sensitivity to emotional signals, we hypothesized that compared with male participants and relative to a neutral control condition, female participants would emulate the fearful state of the sender producing the chemosignals. Facial electromyography was used in a double-blind experiment to measure in the receiver a partial reproduction of the state of the sender, controlling for the moderating influence of the sex of the sender and receiver. The results indicated that only female participants emulated the fearful state of the sender. The present study revealed a boundary condition for effective chemosignaling by reporting behavioral evidence of sexual asymmetry in olfactory communication via chemosignals.
