研究选取56名大学生被试,通过特里尔社会应激测验(trier social stress test,TSST)、记忆和心理韧性测验来探究急性心理应激对大学生记忆效果的影响,以及心理韧性在二者关系中的调节作用。结果表明:(1)相对于非应激组,应激组大学生的整...研究选取56名大学生被试,通过特里尔社会应激测验(trier social stress test,TSST)、记忆和心理韧性测验来探究急性心理应激对大学生记忆效果的影响,以及心理韧性在二者关系中的调节作用。结果表明:(1)相对于非应激组,应激组大学生的整体记忆成绩更差,且应激组中的高应激反应者的记忆成绩比低应激反应者的记忆成绩更差;(2)心理韧性可以调节应激反应与记忆成绩之间的关系,表现为在高心理韧性情况下,大学生的记忆成绩不会随着应激反应程度的升高而产生显著的变化;而在低心理韧性情况下,大学生的记忆成绩会随着应激反应程度的升高而出现显著下降。研究进一步从认知加工资源分配与再分配的视角讨论了心理应激、心理韧性与记忆功能三者间的关系与启示。展开更多
研究旨在考察受欺负经历与儿童下丘脑-垂体-肾上腺轴系统应激功能的关系。根据受欺负得分挑选出52名受欺负和未受欺负儿童,考察两类儿童在特里尔社会应激测验(Trier Social Stress Test,TSST)中的皮质醇分泌及主观紧张度的特征差异。结...研究旨在考察受欺负经历与儿童下丘脑-垂体-肾上腺轴系统应激功能的关系。根据受欺负得分挑选出52名受欺负和未受欺负儿童,考察两类儿童在特里尔社会应激测验(Trier Social Stress Test,TSST)中的皮质醇分泌及主观紧张度的特征差异。结果发现:(1)在TSST中,受欺负者的皮质醇浓度显著高于未受欺负者;(2)两类儿童在TSST中的主观紧张度不存在显著差异。研究结果与慢性应激破坏HPA轴应激功能的过程是从敏化到钝化的理论假说相一致。展开更多
