本研究考察了6月龄婴儿皮质醇的反应性（即峰值反应）和调节性（即反应抑制）与接种行为反应之间的关系（N = 62）。数据显示，皮质醇和行为的反应性和调节是不相关的。反应性和调节的独立性表明，需要对两者进行测量才能更全面地表征婴儿皮质醇或对压力的行为反应。对于反应性和调节，皮质醇和行为都是不相关的，这表明需要对两者进行测量才能更充分地评估婴儿的压力。皮质醇峰值反应的时间有相当大的变化，这表明仅获得单一的应激源皮质醇样本并不能提供皮质醇反应性的敏感测量。
This study examined relations between reactivity (i.e., peak response) and regulation (i.e., response dampening) in 6-month-old infants' cortisol and behavioral responses to inoculation (N = 62). Data showed that reactivity and regulation were unrelated for both cortisol and behavior. The independence of reactivity and regulation suggests that measures of both are needed to characterize infant cortisol or behavioral response to stress more completely. For both reactivity and regulation, cortisol and behavior were unrelated, suggesting that measures of both are needed to assess infant stress more adequately. There was considerable variation in the timing of the peak cortisol response, suggesting that obtaining only a single poststressor cortisol sample does not provide a sensitive measure of cortisol reactivity.
