神经肽催产素和加压素通过增强社会显著性和一般的合作，反复参与社会决策。囚徒困境（PD）博弈的迭代和序列版本是一个社会困境范式，引出合作与竞争的策略。我们的目的是验证PD玩家的性别，游戏伙伴类型（计算机与人类）和催产素或加压素吸入对玩家的策略偏好的作用。参与者（153名男性; 151名女性）随机接受鼻内24 IU催产素、20 IU加压素或安慰剂，双盲，并进行PD。我们研究了性别、药物和伴侣类型对策略偏好的主效应和交互效应。我们发现，在无条件合作的情况下，人们普遍倾向于达特的策略（即对合作伙伴的选择的一般敏感性），特别是在与人类而不是计算机合作伙伴的情况下。催产素使女性在与计算机比赛时的这种敏感性（即对达特的偏好超过无条件合作策略）增加了一倍，这表明女性倾向于将其拟人化，并使女性在与人类比赛时的无条件合作偏好增加了一倍。加压素加倍敏感性合作伙伴的先前的选择（即达特的无条件合作）跨性别和合作伙伴类型。这些研究结果表明，女性可能对催产素的社会效应更敏感，即非人类的拟人化和与人类无条件合作，这可能与母性护理的进化压力相一致，而加压素，无论性别和伴侣类型如何，通常可能会使人类对他人的行为敏感。
The neuropeptides oxytocin and vasopressin have been repeatedly implicated in social decision making by enhancing social salience and, generally, cooperation. The iterated and sequential version of the prisoner’s dilemma (PD) game is a social dilemma paradigm eliciting strategies of cooperation versus competition. We aimed to characterise the role of PD players’ sex, game partner type (computer vs. human) and oxytocin or vasopressin inhalation on the player’s strategy preference. Participants (153 men; 151 women) were randomised to intranasal 24 IU oxytocin, 20 IU vasopressin or placebo, double-blind, and played the PD. We examined main and interactive effects of sex, drug and partner type on strategy preference. We found a pervasive preference for a tit-for-tat strategy (i.e. general sensitivity to the partner’s choices) over unconditional cooperation, particularly when against a human rather than a computer partner. Oxytocin doubled this sensitivity in women (i.e. the preference for tit-for-tat over unconditional cooperation strategies) when playing against computers, which suggests a tendency to anthropomorphise them, and doubled women’s unconditional cooperation preference when playing against humans. Vasopressin doubled sensitivity to the partner’s previous choices (i.e. for tit-for-tat over unconditional cooperation) across sexes and partner types. These findings suggest that women may be more sensitive to oxytocin’s social effects of anthropomorphism of non-humans and of unconditional cooperation with humans, which may be consistent with evolutionary pressures for maternal care, and that vasopressin, irrespective of sex and partner type, may be generally sensitising humans to others’ behaviour.
