Although it is widely accepted that academic examinations are accompanied by a cortisol increase, some recent studies reported either no effect or even a decline of the cortisol level. To reevaluate these discrepancies, we investigated whether personality traits predict the cortisol response upon academic examinations.
Nineteen male and female adolescent pupils (17 to 19 years) participated in the study. Two anticipated, mandatory, routine written examinations were used as familiar stressful conditions, whereas an anticipated, mandatory oral examination in front of a board of known and unknown examiners was used as a novel stressful situation.
Baseline, pre- and postexamination salivary cortisol were quantified and correlated with psychometric measures, including self-estimated stress level, obtained from a five-point scale, and sensation seeking subscales according to Zuckerman.
Salivary cortisol response, taken as an average of all subjects, showed a transient increase upon examinations. However, comparing individual cortisol responses revealed three distinct cortisol profiles, including a transient increase (Type 1), a transient decline (Type 2), or no response (Type 3). Type 1 predominates in examinations combined with novelty. A moderate negative association was noted between saliva cortisol concentrations on some sensation seeking subscales. Self-reported stress levels did not significantly correlate with salivary cortisol concentration.
Our findings show that upon academic examinations the cortisol response varies among subjects. A moderate negative association was unveiled by correlating individual cortisol responses with sensation seeking subscales.
虽然人们普遍认为学术考试会伴随皮质醇水平升高,但最近一些研究报告称没有影响,甚至皮质醇水平有所下降。为了重新评估这些差异,我们调查了人格特质是否能预测学术考试时的皮质醇反应。
19名青少年学生(17至19岁,男女皆有)参与了该研究。两场预期的、强制性的常规笔试被用作熟悉的应激条件,而一场在由熟悉和不熟悉的考官组成的委员会面前进行的预期的、强制性口试被用作新的应激情境。
对基线、考试前和考试后的唾液皮质醇进行定量,并与心理测量指标相关联,包括从五点量表获得的自我估计应激水平,以及根据祖克曼的感觉寻求分量表。
将所有受试者的唾液皮质醇反应作为平均值,在考试时显示出短暂升高。然而,比较个体皮质醇反应发现了三种不同的皮质醇模式,包括短暂升高(1型)、短暂下降(2型)或无反应(3型)。1型在伴有新奇感的考试中占主导。在某些感觉寻求分量表上,唾液皮质醇浓度之间存在中等程度的负相关。自我报告的应激水平与唾液皮质醇浓度没有显著相关性。
我们的研究结果表明,在学术考试中,受试者的皮质醇反应各不相同。通过将个体皮质醇反应与感觉寻求分量表相关联,发现了中等程度的负相关。
