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 tone and changes in cardiac vagal tone during social/attention challenges. Infants with higher baseline cardiac vagal tone were rated in the laboratory as showing 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.
60名12周大的婴儿参与了一项实验室研究，以探索气质与心脏迷走神经张力之间的关系。通过实验室观察和母亲的评分对气质进行评估。心脏迷走神经张力以呼吸性窦性心律不齐的幅度来衡量，根据在静息基线期和气质实验室评估期间收集的逐搏心动周期数据进行量化。研究了关于气质与基础心脏迷走神经张力以及社交/注意力挑战期间心脏迷走神经张力变化之间关系的具体假设。基线心脏迷走神经张力较高的婴儿在实验室中被评为表现出较少的负面行为，并且受实验程序的干扰较小。在实验室评估期间心脏迷走神经张力降低的婴儿，在母亲报告的气质量表上被评为注意力持续时间更长，并且更容易安抚。
