睾丸素以各种方式影响人类的社会行为。虽然睾酮效应通常与肌肉力量和攻击性有关，但人类研究也指出，服用睾酮后，寻求地位的动机会增强。目前的研究测试了外源性睾酮对男性行为的因果影响在竞争挑衅范式。在这项双盲、随机、安慰剂（PL）对照研究中，103名男性被分配到PL或睾酮组，接受无色PL或睾酮凝胶。为了诱导挑衅，雄性与一个表面上的对手玩了一个操纵的反应时间游戏。当参与者输了，对手从参与者身上减去钱，参与者也可以从表面上的对手身上减去钱。参与者主观表示愤怒和自我评估治疗从属关系（睾酮或PL管理）。一项逐个试验的分析表明，在重复的游戏中，如果参与者接受了睾丸激素，那么他们在选择减少对手的钱方面，受到挑衅和成功的影响更大。那些被认为是睾酮组的参与者在实验结束后更加愤怒，并且在任务过程中减少了更多的钱。与人类睾酮机制的理论一致，刺激被证明是外源性睾酮作用的必要条件。因此，睾酮加强了攻击行为的条件调整，而不是攻击行为本身。相反，非定向挫折不会因睾酮而增加，但可能会干扰对睾酮生物学机制的认知评价。
Testosterone affects human social behavior in various ways. While testosterone effects are generally associated with muscular strength and aggressiveness, human studies also point towards enhanced status–seeking motives after testosterone administration. The current study tested the causal influence of exogenous testosterone on male behavior during a competitive provocation paradigm. In this double blind, randomized, placebo (PL)-controlled study, 103 males were assigned to a PL or testosterone group receiving a colorless PL or testosterone gel. To induce provocation, males played a rigged reaction time game against an ostensible opponent. When participants lost, the opponent subtracted money from the participant who in return could subtract money from the ostensible opponent. Participants subjectively indicated anger and self-estimated treatment affiliation (testosterone or PL administration). A trial-by-trial analysis demonstrated that provocation and success during the repeated games had a stronger influence on participants’ choice to reduce money from the opponent if they had received testosterone. Participants who believed to be in the testosterone group were angrier after the experiment and increased monetary reductions during the task course. In line with theories about mechanisms of testosterone in humans, provocation is shown to be necessary for the agency of exogenous testosterone. Thus, testosterone reinforces the conditional adjustment of aggressive behavior but not aggressive behavior per se. In contrast undirected frustration is not increased by testosterone but probably interferes with cognitive appraisals about biological mechanisms of testosterone.
