这项研究证实了出生前神经行为功能存在稳定的个体差异，并检验了它们与随后婴儿气质的关系。从妊娠 20 周开始，纵向记录 31 个 6 胎龄胎儿的胎心率和胎动。在 3 个月和 6 个月时收集母亲报告的气质数据。除反应性外，所有指标均在出生前的某个时间表现出中等稳定性。到 36 周时，胎儿神经行为占气质评分预测方差的 22% 至 60%。一般来说，越活跃的胎儿就越困难、难以预测、难以适应、也越活跃。较高的胎心率与较低的情绪基调、活动水平和可预测性相关。我们的结论是，胎儿神经行为的特征为婴儿期反应和调节的个体差异提供了基础。
This study established the emergence of stable individual differences in neurobehavioral functioning prior to birth and examined their relation to subsequent infant temperament. Fetal heart rate and movement were recorded longitudinally for 31 fetuses at 6 gestational ages beginning at 20 weeks' gestation. Maternally reported temperament data were collected at 3 and 6 months. Moderate stability in all measures except reactivity was apparent at some time before birth. By 36 weeks, fetal neurobehavior accounted for between 22% and 60% of the variance in prediction of temperament scores. In general, more active fetuses were more difficult, unpredictable, unadaptable, and active infants. Higher fetal heart rate was associated with lower emotional tone, activity level, and predictability. We conclude that features of fetal neurobehavior provide the basis for individual differences in reactivity and regulation in infancy.
