照顾者拥抱他们的婴儿，表达爱意和喜悦。然而，目前还不清楚婴儿被拥抱时会有什么反应。在这里，我们研究了一岁婴儿在父母拥抱、拥抱和紧紧拥抱时的心率反应。四个月大的婴儿在拥抱期间R-R间期(RRI)增加，表明心率减慢和明显的副交感神经活动。很少有头部运动预测，与拥抱和紧紧拥抱相比，父母拥抱期间婴儿的RRI增加更高。在一个陌生女性的拥抱中，婴儿并没有表现出增加的RRI。4个月以下的婴儿在父母拥抱期间没有表现出RRI增加，但表现出与接触压力相关的RRI下降。父母在拥抱婴儿的过程中表现出更高的RRI。这些结果表明，亲子拥抱是亲子关系和婴儿心理生理发展的基础。
Caregivers hug their infants to express affection and joy. However, it remains unknown how infants react to being hugged. Here we examined heart rate responses in first-year infants during a hug, hold, and tight hug from parents. Infants older than four months showed an increased R-R interval (RRI) during a hug, indicating reduced heart rates and pronounced parasympathetic activity. Few head movements predicted a higher RRI increase in infants during a parental hug compared with that during a hold and tight hug. Infants did not show an increased RRI during a hug from a female stranger. Infants younger than four months did not show RRI increase during parental hug but exhibited a decreased RRI correlated with contact pressure. Parents showed an increased RRI during hugging their infants. These results suggest the parent-infant hug underlies the parent-infant bonding and psychophysiological development of infants.
