The finding that chewing gum can moderate state anxiety under conditions of acute stress has proved difficult to replicate. The present study examines the extent to which chewing gum can moderate state anxiety under conditions of acute social stress.
In a between-participants design, 36 participants completed a task comprising a mock job interview (a variation on the Trier Social Stress Task, which included a mental arithmetic component) while either chewing gum or without chewing gum. Self-rated measures of mood and anxiety were taken at baseline, after a 10-minute presentation preparation stage, after the 10-minute presentation, and following a 5-minute recovery stage.
Post-presentation measures reflected increased state anxiety and decreased self-rated calmness and contentedness. Chewing gum attenuated the rise in state anxiety while increasing self-rated alertness. Chewing gum did not affect contentedness or calmness.
The findings indicate that chewing gum can act to reduce anxiety under conditions of acute social stress: a finding consistent with Scholey et al. Furthermore, the data add to the growing body of literature demonstrating that chewing gum can increase alertness.
咀嚼口香糖可以调节急性应激状态下的状态焦虑,这一发现很难被复制。本研究考察了咀嚼口香糖在急性社交应激下调节状态焦虑的程度。
在一项参与者间设计的研究中,36 名参与者在咀嚼或不咀嚼口香糖的情况下完成了一项模拟工作面试的任务(一种改编的特里尔社会应激测试,包括心算部分)。在基线、10 分钟的演讲准备阶段后、10 分钟的演讲后和 5 分钟的恢复阶段后,对情绪和焦虑的自我评估进行了测量。
演讲后的测量结果反映出状态焦虑增加,自我评估的平静和满足感降低。咀嚼口香糖减轻了状态焦虑的上升,同时提高了自我评估的警觉性。咀嚼口香糖对满足感或平静感没有影响。
这些发现表明,咀嚼口香糖可以在急性社交应激下减轻焦虑:这一发现与 Scholey 等人的研究一致。此外,这些数据增加了越来越多的文献,证明咀嚼口香糖可以提高警觉性。
