本研究旨在检查（a）在婴儿、年轻人和老年人中观察到的与认知能力相关的心血管反应性增加的结果是否可以扩展到儿童中期，以及（B）智力的哪些特定方面与心血管反应性相关。我们检查了340名8岁和9岁儿童在数字判断任务中的心血管活动，并使用WISC-IV测量了液体和晶体智商。回归分析显示，心率（HR）反应性与流体智力和知觉推理，特别是控制的影响，性别，年龄，任务的表现，社会逆境，和静息HR. Intelligence分数不相关的呼吸性窦性心律失常（RSA）的反应。研究结果与婴儿和老年人群的先前文献一致，并首次表明HR反应性和认知能力之间的关联是特定于流体推理的。
This study aimed to examine (a) whether findings of increased cardiovascular reactivity in relation to cognitive ability seen in infants, young adults and the elderly can be extended to middle childhood, and (b) which specific aspect(s) of intelligence is related to cardiovascular reactivity. We examined cardiovascular activity in 340 8- and 9-year-old children during a number judgment task and measured fluid and crystalized IQ using the WISC-IV. Regression analyses revealed that heart rate (HR) reactivity was positively associated with fluid intelligence and perceptual reasoning in particular, after controlling for the effects of sex, age, task performance, social adversity, and resting HR. Intelligence scores were not associated with respiratory sinus arrhythmia (RSA) reactivity. Findings are consistent with prior literature in infants and older populations and for the first time suggest that the association between HR reactivity and cognitive ability is specific for fluid reasoning.
