Salivary alpha-amylase (sAA) has gained popularity as an easily collected biomarker for sympathetic nervous system activation, and research has shown increases in sAA after completing experimental stress tasks in certain groups. However, recent work suggests that salivary cortisol, another stress biomarker, is suppressed after a speech task among experimentally induced exclusion in young women. The present analysis investigated the sAA response in biologically female undergraduates (n=31) who completed a game of Cyberball and then a speech anticipation task. Results showed that women in the social exclusion experimental group had a greater decrease in sAA compared to young women in the inclusion group after the speech task. Results of this study provide support for stress response suppression in women who have experienced social exclusion. The present findings provide pilot evidence for future, larger studies to advance the tend-and-befriend theory.

被排除在外的年轻女性在完成演讲任务后唾液 α-淀粉酶反应性降低

唾液 α-淀粉酶 (sAA) 作为一种易于收集的交感神经系统激活生物标志物而广受欢迎，研究表明，在某些群体中完成实验性应激任务后，sAA 会增加。然而，最近的研究表明，在实验诱导的年轻女性排斥中，唾液皮质醇（另一种压力生物标志物）在完成言语任务后受到抑制。本分析调查了生物学上的女性本科生 (n=31) 的 sAA 反应，这些学生完成了网络球游戏，然后完成了言语预期任务。结果显示，与包容组的年轻女性相比，社会排斥实验组的女性在完成演讲任务后，sAA 下降幅度更大。这项研究的结果为经历过社会排斥的女性抑制压力反应提供了支持。目前的研究结果为未来更大规模的研究提供了初步证据，以推进“照顾与友善”理论。
