我们研究了唾液皮质醇，α-淀粉酶（sAA），和儿童的认知和学业功能之间的关系。感兴趣的是这些唾液测量对认知和学业表现的曲线和交互作用。数据基于美国东南部的28名男孩和36名女孩（8岁和9岁）的样本。儿童完成智力标准化测试，学校提供学业成绩信息。回归分析表明，显着的曲线关系和皮质醇和sAA之间的相互作用，在儿童功能的预测。与目前生物系统之间相互作用的模型相反，研究结果表明，一些最高和最低的分数是在中等水平的生理唤醒下预测的。例如，患有中度sAA和较高或较低皮质醇的儿童的阅读能力预测得分较低。具有中等皮质醇和较低sAA的儿童具有最高的智力预测分数。研究结果表明，生物应激反应系统之间的相互作用的研究不应该基于直线相互作用的模型。(C)2011年由Elsevier Inc.出版
We examined relations between salivary cortisol, alpha-amylase (sAA), and children's cognitive and academic functioning. Of interest were curvilinear and interactive effects of these salivary measures on cognitive and academic performance. Data were based on a sample of 28 boys and 36 girls (ages 8 and 9) in the Southeastern U.S.A. Children provided resting afternoon saliva samples. Children completed standardized tests of Intellectual Ability and schools provided academic achievement information. Regression analyses demonstrated significant curvilinear relations and interactions between cortisol and sAA in the prediction of child functioning. Contrary to current models of interactions among biological systems, findings indicated some of the highest and lowest scores were predicted at moderate levels of physiological arousal. For example, children with moderate sAA and either higher or lower cortisol had low predicted scores for Reading Ability. Children with moderate cortisol and lower sAA had the highest predicted scores for Intellectual Ability. Findings suggest that the study of interactions between biological stress response systems should not be based on models of rectilinear interactions. (C) 2011 Published by Elsevier Inc.
