The interactionist approach to the study of exogenous oxytocin (OT) effects on prosocial behavior has emphasized the need to consider both contextual cues and individual differences. Therefore, an experiment was set up to examine the joint effect of intranasal OT, a salient social cue and the personality trait social value orientation on cooperative behavior in one-shot prisoner's dilemma games. The outcome of these mixed-motive games is known to be highly dependent on values and on social information that might reveal the partner's intent. Consistent with an a priori hypothesis, OT and social information interact significantly to affect the behavior of individuals with a proself value orientation: after prior contact with the game partner, OT enhances cooperative behavior, whereas in anonymous conditions, it exacerbates their intrinsic self-interested behavior. These effects of OT do not hold for individuals with a prosocial value orientation, whose cooperation levels appear to be more influenced by prior contact with the game partner. Follow-up hypotheses for why prosocial and proself individuals respond differently to exogenous OT were developed.
交互作用方法强调需要同时考虑情境线索和个体差异，以研究外源性催产素（OT）对亲社会行为的影响。因此，进行了一项实验，以检验鼻内 OT、显著的社会线索和社会价值取向人格特质对单次囚徒困境游戏中合作行为的联合影响。众所周知，这些混合动机游戏的结果高度依赖于价值观和可能揭示伙伴意图的社会信息。与先验假设一致，OT 和社会信息显著相互作用，影响具有自我价值取向的个体的行为：在与游戏伙伴事先接触后，OT 增强了合作行为，而在匿名条件下，它加剧了他们内在的自利行为。OT 的这些作用不适用于具有亲社会价值取向的个体，他们的合作水平似乎更多地受到与游戏伙伴事先接触的影响。为了探究为什么亲社会和自我个体对外源性 OT 的反应不同，提出了后续假设。
