Cortisol levels at three time points (S1/S2/S3) during the cognitive tasks (nmol/L).

S1 = cortisol level before the cognitive tasks; S2 = cortisol level during the cognitive tasks; S3 = cortisol level after the cognitive tasks; Mean = mean value of the three cortisol samples; AUCg = area under the curve with reference to the ground; SD = standard deviation.Cortisol levels at three time points (S1/S2/S3) during the cognitive tasks (nmol/L).

S1 = 认知任务实施前的皮质醇（cortisol）水平；S2 = 认知任务进行中的皮质醇水平；S3 = 认知任务完成后的皮质醇水平；均值（Mean）= 三份皮质醇样本的平均值；AUCg = 以基线为参照的曲线下面积；标准差（SD）= 标准差。认知任务期间三个时间点（S1/S2/S3）的皮质醇水平单位为纳摩尔每升（nmol/L）。
