婴儿的哭声会引起敏感的哭闹，以及敌意和严厉的父母反应。在目前的研究（N = 42名女性）中，采用双盲实验设计，我们测试了鼻内催产素给药对使用过度用力的影响，使用手柄测力计，在听婴儿哭泣的声音。研究发现，参与者在童年时期受到严厉的父母管教的经历，会缓和催产素对过度使用武力的影响。父母没有严厉管教的参与者在催产素条件下使用的过度武力较少，但对于受到严厉管教的参与者，催产素和安慰剂条件之间没有差异。在听婴儿笑声时没有发现这种影响。我们的结论是，早期怀孕的经验构成了催产素的亲社会和/或减压作用的一个重要的主持人。催产素的管理可能会增加信任和合作的个人支持的背景，但不会产生这种效果的个人作为一个不利的早期经历的结果可能有偏见的负面解释的社会线索。
Infant crying can elicit sensitive caregiving as well as hostility and harsh parenting responses. In the current study (N = 42 females) with a double-blind experimental design, we tested the effect of intranasal oxytocin administration on the use of excessive force using a hand-grip dynamometer during listening to infant cry sounds. Participants' experiences with harsh parental discipline during childhood were found to moderate the effect of oxytocin administration on the use of excessive force. Participants' whose parents did not discipline them harshly used less excessive force in the oxytocin condition, but for participants who were disciplined harshly there was no difference between the oxytocin and placebo condition. Such effects were not found during listening to infant laughter. We conclude that early caregiving experiences constitute an important moderator of the prosocial and/or stress-reducing effects of oxytocin. Oxytocin administration may increase trust and cooperation in individuals with supportive backgrounds, but not generate this effect in individuals who as a consequence of unfavorable early caregiving experiences may have a bias toward negative interpretation of social cues.
