ABSTRACT

In the last decades, parenting researchers increasingly focused on the role of fathers in child development. However, it is still largely unknown which factors contribute to fathers’ beliefs about their child, which may be crucial in the transition to fatherhood. In the current randomized within-subject experiment, the effect of nasal administration of vasopressin (AVP) on both Five Minute Speech Sample-based (FMSS) expressed emotion and emotional content or prosody was explored in 25 prospectivefathers. Moreover, we explored how the transition to fatherhood affected these FMSS-based parameters, using prenatal and early postnatal measurements. Analyses revealed that FMSS-based expressed emotion and emotional content were correlated, but not affected by prenatal AVP administration. However,child’s birth was associated with an increase in positivity and a decrease in emotional prosody, suggesting that the child’s birth is more influential with regard to paternal thoughts and feelings than prenatal AVP administration.

摘要

在过去的几十年里，育儿研究人员越来越关注父亲在儿童发展中的作用。然而，在很大程度上仍不清楚哪些因素会影响父亲对孩子的信念，这可能是向父亲过渡的关键。在目前的随机受试者内实验中，对 25 名准父亲进行了鼻腔施用加压素 (AVP) 对基于五分钟语音样本 (FMSS) 表达的情绪和情绪内容或韵律的影响。此外，我们使用产前和产后早期测量探索了向父亲的转变如何影响这些基于 FMSS 的参数。分析表明，基于 FMSS 的表达情绪和情绪内容是相关的，但不受产前 AVP 管理的影响。然而，
