Abstract

This study examined whether parental sensitivity during distressing and non‐distressing mother–infant interactions predicts changes in young children's respiratory sinus arrhythmia (RSA) activity. Baseline RSA levels were collected from 83 children (49% female, 51% male) when children were 7 and 18 months old. Children's RSA reactivity and RSA recovery during the still‐face paradigm were collected when children were 7 months and during the strange situation procedure at 18 months. Controlling for stability of RSA activity over time, maternal sensitivity during distressing interactions at 7 months predicted changes in children's baseline RSA levels (β = −0.30) and children's RSA recovery (β = 0.25). Young children who experienced higher levels of sensitivity at 7 months had lower resting RSA levels and exhibited greater RSA recovery at 18 months. These results suggest that changes in young children's RSA activity are meaningfully related to their early caregiving experiences.Highlights

We examined whether maternal sensitivity during infancy predicts changes in children's RSA activity from infancy to toddlerhood.

Children who experienced higher levels of maternal sensitivity during infancy showed greater RSA recovery from a stressor during toddlerhood.

Children who experienced higher levels of maternal sensitivity during infancy had lower resting RSA levels during toddlerhood.

母亲的敏感性是婴儿期到幼儿期呼吸窦性心律失常活动变化的预测因素

本研究探讨了父母在困扰和非困扰的母婴互动中的敏感性是否能预测幼儿呼吸窦性心律失常（RSA）活动的变化。研究收集了 83 名儿童（49% 为女性，51% 为男性）在 7 个月和 18 个月大时的基线 RSA 水平。在儿童 7 个月大和 18 个月大时，分别收集了他们在静止面孔范例中的 RSA 反应性和 RSA 恢复情况。在控制了 RSA 活动随时间变化的稳定性后，7 个月大时母亲在痛苦互动中的敏感性预测了儿童基线 RSA 水平的变化（β = -0.30）和儿童 RSA 恢复的变化（β = 0.25）。7 个月时敏感度较高的幼儿静态 RSA 水平较低，18 个月时 RSA 恢复程度较高。这些结果表明，幼儿 RSA 活动的变化与他们早期的照料经历有重要关系。亮点我们研究了母亲在婴儿期的敏感性是否能预测儿童从婴儿期到学步期 RSA 活动的变化。婴儿期母亲敏感度较高的儿童在幼儿期从压力中恢复 RSA 的能力较强。婴儿期母性敏感度较高的儿童在学步期的静息 RSA 水平较低。
