围产期的特点是由产前开始的独特的神经生物学和心理变化，这可能既促进产后抑郁，又增加对压力的脆弱性。父母需要适应婴儿的高要求，包括对婴儿的明显暗示做出反应，比如婴儿的哭声。因此，评估产前压力暴露对父母的婴儿哭声的神经处理的影响，可能会阐明机制，赋予有害的围产期结局的早期风险。使用事件相关电位，我们检查了产前感知压力是否影响了感知（N1，P2）和注意（LPP）过程的神经标记，这些过程由孕妇（n = 38）和父亲（n = 30）的高和低痛苦婴儿哭声引起。结果证明，产前感知压力影响父母对婴儿哭声的持续注意力处理（LPP），但不影响早期知觉反应（N1、P2）。具体来说，产前感知压力水平较高与LPP对低痛苦的反应有关，但不是高痛苦，婴儿哭声。有没有父母的性别差异，产前感知的压力或神经反应婴儿哭声。高度压力的父母对低痛苦哭声的注意力处理增加可能反映了对婴儿痛苦水平的不确定性，从而需要更多的注意力资源。总的来说，我们的研究结果表明，产前压力影响婴儿线索的处理，甚至在出生前。
The perinatal period is characterized by distinct neurobiological and psychological changes initiated prenatally, which may both facilitate postpartum caregiving and increase vulnerability to stress. Parents need to adapt to the high demands of caregiving, which include responding to salient infant cues, such as infant cries. Therefore, assessing the impact of prenatal stress exposure on parents’ neural processing of infant cries may elucidate mechanisms conferring early risk for detrimental perinatal outcomes. Using event‐related potentials, we examined whether prenatal perceived stress affected neural markers of perceptual (N1, P2) and attentional (LPP) processes elicited by high‐ and low‐distress infant cries in expectant mothers (n= 38) and fathers (n= 30). Results evidenced that prenatal perceived stress impacted parents’ sustained attentional processing (LPP) of infant cries, but not early perceptual responses (N1, P2). Specifically, higher levels of prenatal perceived stress were associated with a greater LPP response to low‐distress, but not high‐distress, infant cries. There were no parental sex differences in prenatal perceived stress or neural responses to infant cries. Increased attentional processing of low‐distress cries in highly stressed parents may reflect uncertainty regarding infant distress level, thereby requiring more attentional resources. Overall, our results suggest that prenatal stress impacts processing of infant cues, even before birth.
