背景：在生命的最初几年，养育被认为对于调节婴儿的情绪和生理状态很重要。在本研究中，检查了三个月大婴儿的皮质醇对日常轻微压力源（即从浴缸中取出）的皮质醇反应（反应性和恢复性）与母亲行为质量的关系。据推测，母亲对婴儿的行为质量越高，皮质醇反应性就越低，并且从反应中恢复得越好。方法：参与者为 64 名婴儿（34 名男孩和 30 名女孩）及其母亲。根据录像对洗澡过程中母亲对婴儿的行为（敏感度和合作性）进行评估。采集婴儿唾液皮质醇 3 次：洗澡前（T1）、婴儿出浴后 25 分钟（T2）和 40 分钟（T3）。结果：婴儿对压力源的反应是皮质醇显着增加（从 6.8 nmol/l 到 9.9 nmol/l），回归分析显示，母亲行为质量越高，皮质醇从压力源中恢复得越好。结论：我们的研究结果表明，社会过程对于婴儿从日常压力情况下的生理恢复具有潜在的重要性。
Background: In the very first years of life, parenting is considered to be important for the regulation of the infant's emotional and physiological states. In the present study, three-month-old infants' cortisol responses (reactivity and recovery) to a mild everyday stressor, namely being taken out of the bath, were examined in relation to the quality of maternal behavior. It was hypothesized that a higher quality of maternal behavior towards the infant predicted lower cortisol reactivity as well as a better recovery from the reaction. Method: The participants were 64 infants (34 boys and 30 girls) and their mothers. Maternal behavior (sensitivity and cooperation) towards the infant during the bathing routine was rated from videotapes. Salivary cortisol was obtained from the infants three times: before the bathing routine (T1), and 25 minutes (T2) and 40 minutes (T3) after the infants were taken out of the bath. Results: The infants reacted with a significant increase in cortisol to the stressor (from 6.8 nmol/l to 9.9 nmol/l), and regression analysis showed that the higher the quality of maternal behavior the better the cortisol recovery from the stressor. Conclusion: Our findings indicate the potential importance of social processes for physiological recovery from everyday stressful situations in infants.
