60名12周大的婴儿参加了一项实验室研究，以探索气质和心脏迷走神经张力之间的关系。通过实验室观察和母亲评分来评估气质。心脏迷走神经张力，以呼吸性窦性心律失常的幅度测量，根据在静息基线期间和在气质实验室评估期间收集的心跳至心跳周期数据进行量化。在社交/注意力挑战中，研究人员调查了气质与心迷走神经基础音调和心迷走神经张力变化之间的关系。在实验室中，基线迷走神经张力较高的婴儿表现出较少的负面行为，且较少受到实验程序的干扰。在实验室评估期间心脏迷走神经张力降低的婴儿在母亲报告气质量表上被评为注意力持续时间更长，更容易得到抚慰。
Sixty 12-week-old infants participated in a laboratory study to explore the relations between temperament and cardiac vagal tone. Temperament was evaluated via laboratory observations and maternal ratings. Cardiac vagal tone, measured as the amplitude of respiratory sinus arrhythmia, was quantified from beat-to-beat heart period data collected during a resting baseline period and during the laboratory assessment of temperament. Specific hypotheses were investigated relating temperament to both basal cardiac vagal tune and changes in cardiac vagal tone during social/attention challenges. Infants with higher baseline cardiac vagal tone were rated in the laboratory as showings fewer negative behaviors and were less disrupted by the experimental procedure. Infants who decreased cardiac vagal tone during the laboratory assessment were rated on maternal report temperament scales as having longer attention spans, and being more easily soothed.
