越来越多的证据表明，自主神经系统和肾上腺皮质系统协调行动，以促进对环境的机会和威胁的反应。在目前的研究中，我们使用聚类分析，以检查是否与家长报告的气质积极和消极的情感在36个月大的儿童的自主神经系统的副交感神经和交感神经分支之间的联合基线活动的模式的个体差异。所得到的聚类对应于敏感的、缓冲的和警惕的模式，如压力响应的自适应校准模型所预测的（Del Giudice等人，2011年），包括一个新的模式。集群成员预测整体消极情感及其分量表的差异，但没有发现与积极情感。这些结果提供了证据，表明在休息时生理系统的联合活动可能是负面情绪的气质差异的基础。
Evidence has accrued to show that autonomic and adrenocortical systems act in coordination to facilitate responses to environmental opportunities and threats. In the current study, we used cluster analysis to examine whether individual differences in patterns of joint baseline activity among the parasympathetic and sympathetic branches of the autonomic nervous system with the hypothalamic-pituitary-adrenal axis are associated with parent-reported temperamental positive and negative affectivity in 36-month old children. The resulting clusters corresponded to the sensitive, buffered, and vigilant patterns as predicted by the adaptive calibration model of stress responsivity (Del Giudice et al., 2011) and included a novel pattern. Cluster memberships predicted differences in overall negative affectivity and its subscales, but no associations were found with positive affectivity. These results provide evidence that the joint activity of physiological systems at rest may underlie temperamental differences in negative affect.
