为了确定新父亲和非父亲对婴儿暗示的反应，我们让父亲和非父亲接触婴儿的哭声并控制刺激，我们测量了情感、心率和内分泌反应，包括哭泣前后的唾液睾酮和皮质醇以及血浆催乳素浓度。我们发现：(1)听到哭声的父亲比没有听到哭声的父亲或没有听到哭声的父亲感到更有同情心和警觉性；(2)睾酮水平较低的父亲和没有父亲的父亲比睾酮水平较高的父亲有更高的同情心和/或需要对婴儿的哭声做出反应；(3)催乳素水平较高的父亲对哭声的反应也更警觉和积极；(4)听到哭泣刺激的父亲比没有听到哭泣刺激的父亲显示出更大比例的睾酮增加；(5)有经验的父亲听到哭声时，催乳素水平比第一次听到哭声的父亲或任何一组父亲的听力控制刺激都有更大的百分比增加；(6)与胎次和经历作为协变量的偏相关表明，经历和睾酮都是父亲对婴儿哭声的情感反应差异的原因。综上所述，这些结果表明，与其他一些双亲物种一样，人类父亲对婴儿暗示的反应比非父亲更敏感，父亲对婴儿暗示的反应与荷尔蒙和照料经验都有关。(C)2002年埃尔塞维尔科学公司(美国)。
To determine the responsiveness of new fathers and non-fathers toward infant cues, we exposed fathers and non-fathers to infant cries and to control stimuli and we measured affective, heart-rate, and endocrine responses, including salivary testosterone and cortisol and plasma prolactin concentrations prior to and after cry presentations. We found that (1) fathers hearing the cry stimuli felt more sympathetic and more alert compared to groups who did not hear the cries or to non-fathers who heard the cries; (2) fathers and non-fathers with lower testosterone levels had higher sympathy and/or need to respond to the infant cries than fathers with higher testosterone levels; (3) fathers with higher, as opposed to lower, prolactin levels were also more alert and more positive in response to the cries; (4) fathers hearing the cry stimuli showed greater percentage increase in testosterone than fathers not hearing the cry stimuli; (5) experienced fathers hearing the cries showed a greater percentage increase in prolactin levels compared to first-time fathers or to any group of fathers hearing control stimuli; finally, (6) partial correlations with parity and experience entered as a covariates indicated that both experience and testosterone contributed to the variance in fathers' affective responses to infant cries. Taken together, these results indicate that, as with a number of other biparental species, human fathers are more responsive to infant cues than are non-fathers and fathers' responses to infant cues are related to both hormones and to caregiving experience.
