The stability of infant temperament and autonomic patterning (heart period and cardiac vagal tone) was examined longitudinally when infants were 5, 10, and 18 months of age. Behavioral measures of reactivity and regulation to frustration tasks, and maternal perceptions of infant temperament were obtained at each age along with baseline measures of cardiac activity. No stability was found from 5 to 10 months while some stability of behavior and autonomic patterning was identified from 10 to 18 months, with the exception of negative reactivity. High levels of cardiac vagal tone (V) were associated with negative reactivity at 18 months. When examining groups based on degrees of reactivity and regulation, we found infants who responded negatively to frustration but who also displayed more regulatory behavior to have higher V.
在婴儿5个月、10个月和18个月大时，对其气质稳定性和自主模式（心搏间期和心脏迷走神经张力）进行了纵向研究。在每个年龄段，除了获取心脏活动的基线测量值外，还获得了对挫折任务的反应性和调节的行为测量值，以及母亲对婴儿气质的看法。5至10个月期间未发现稳定性，而10至18个月期间发现了一些行为和自主模式的稳定性，但消极反应性除外。18个月时，高心脏迷走神经张力（V）与消极反应性相关。在根据反应性和调节程度对组进行检查时，我们发现对挫折有消极反应但也表现出更多调节行为的婴儿具有更高的V值。
