Chemosensory communication is ubiquitous in human social interaction. Androstadienone is a potential candidate human sex pheromone that is associated with social dominance and competition. The aim of the present study was to investigate the effects of androstadienone on aggression. We specifically distinguished two types of aggression, namely proactive and reactive aggression. Two hundred and six male and female participants received either androstadienone or a control carrier in a double-blind, placebo-controlled, between-participants design. Participants performed two aggression tasks, one on reactive aggression and the other on proactive aggression, while they were exposed to the olfactory stimuli. The results revealed that for men, smelling androstadienone reduced both reactive and proactive aggression, whereas it increased reactive aggression in women. These effects were present despite the olfactory stimuli not being explicitly discriminable. These findings provide direct evidence that androstadienone modulates human aggression in a sex-dependent manner.
嗅觉通讯在人类社交互动中无处不在。雄甾烯酮是一种潜在的人类性信息素，与社会支配和竞争有关。本研究旨在探讨雄甾烯酮对攻击性的影响。我们特别区分了两种类型的攻击性，即主动性攻击性和反应性攻击性。206 名男性和女性参与者在双盲、安慰剂对照、被试间设计中接受了雄甾烯酮或对照载体的处理。参与者在暴露于嗅觉刺激的同时进行了两项攻击性任务，一项是反应性攻击性，另一项是主动性攻击性。结果表明，对于男性来说，闻到雄甾烯酮会降低反应性和主动性攻击性，而对女性来说，它会增加反应性攻击性。这些影响存在，尽管嗅觉刺激无法明确区分。这些发现提供了直接证据，表明雄甾烯酮以性别依赖的方式调节人类的攻击性。
