ABSTRACT

Infant-cue processing facilitates sensitive maternal care, which is necessary in the formation of healthy mother-infant attachment. Mothers may be particularly focused on cue processing early postpartum, contributing to intense preoccupation with their infant’s well-being. Prior reproductive experience, or parity, may also impact the intensity of infant-cue processing and has been found to influence P300 neural responses to infant faces during pregnancy and at 2 months postpartum. However, we do not know whether this parity effect persists. Thus, we examined the P300 to infant faces in 59 mothers at 2 and 7 months postpartum. Our main finding was that primiparous, as compared to multiparous, women showed a significantly higher P300 to infant faces across the postpartum period. Findings further emphasize the importance of studying parity and its impact on the neural processing of infant faces.

先前的生殖经验调节产后对婴儿面部的神经反应

摘要

婴儿线索处理促进敏感的母亲护理,这对于形成健康的母婴依恋是必要的。母亲可能特别关注产后早期的线索处理,从而导致对婴儿健康的强烈关注。先前的生殖经验或产次也可能影响婴儿线索处理的强度,并且已发现影响怀孕期间和产后 2 个月时婴儿面部的 P300 神经反应。然而,我们不知道这种平价效应是否持续存在。因此,我们检查了 59 位母亲在产后 2 个月和 7 个月时婴儿面部的 P300。我们的主要发现是,与经产妇女相比,初产妇女在整个产后期间婴儿面部的 P300 显着更高。
