催产素与对社会中介信息（如面部表情）的感知和反应的差异有关。然而，在所有的研究中，催产素对情绪感知的影响并不一致。在实验室之外，情绪感知涉及对感知不确定性的解释和对行为风险的评估。关于催产素对情绪感知的影响的研究中，很大程度上缺少对这些因素的解释，这可能解释了不同研究中不一致的结果。与此相关的是，关于催产素对学习和决策的影响的研究表明，催产素减弱了风险规避。我们使用遇到愤怒面孔的概率和错误识别他们为不愤怒的成本来创建一个风险环境，其中将面孔归类为愤怒的偏见将使积分收益最大化。与低估造成风险的因素一致（即，遭遇率和成本），给予催产素的男性表现出更差的（即，较少自由）的反应偏差。催产素并不影响女性的表现。这些结果表明，催产素可能会损害男性的能力，以适应变化的风险和不确定性时，介绍到新的或不断变化的社会环境。由于催产素也影响非社会领域的行为，催产素药物治疗可能会产生意想不到的后果（即，风险倾向的决策），同时使病态的社会交往正常化。
Oxytocin is associated with differences in the perception of and response to socially mediated information, such as facial expressions. Across studies, however, oxytocin’s effect on emotion perception has been inconsistent. Outside the laboratory, emotion perception involves interpretation of perceptual uncertainty and assessment of behavioral risk. An account of these factors is largely missing from studies of oxytocin’s effect on emotion perception and might explain inconsistent results across studies. Of relevance, studies of oxytocin’s effect on learning and decision-making indicate that oxytocin attenuates risk aversion. We used the probability of encountering angry faces and the cost of misidentifying them as not angry to create a risky environment wherein bias to categorize faces as angry would maximize point earnings. Consistent with an underestimation of the factors creating risk (i.e., encounter rate and cost), men given oxytocin exhibited a worse (i.e., less liberal) response bias than men given placebo. Oxytocin did not influence women’s performance. These results suggest that oxytocin may impair men’s ability to adapt to changes in risk and uncertainty when introduced to novel or changing social environments. Because oxytocin also influences behavior in non-social realms, oxytocin pharmacotherapy could have unintended consequences (i.e., risk-prone decision-making) while nonetheless normalizing pathological social interaction.
