背景种族相关应激源的经历与生理应激反应有关。然而，很多是未知的仍然是如何种族相关的压力感知和经验和潜在的主持人，如强度的种族identity.PurposeThis研究探讨的影响，现实生活中的压力和强度的种族身份对生理反应的社会评价的威胁在laborator.MethodsSalivary皮质醇的措施，收集了整个压力协议。在实验任务之前，非裔美国人的参与者也被随机分配到两种旨在促进种族认同或学生认同的条件之一。出乎意料的是，在数据收集过程中，发生了一个广为人知的现实生活中的种族压力源，杜克长曲棍球（LaX）丑闻。这使得前后LaX比较上的皮质醇levels.ResultsThese比较表明，在两个启动条件下，参与者后LaX有高度升高的皮质醇水平，是无反应的实验压力任务，而他们的前LaX同行有较低的皮质醇水平，表现出正常的压力反应模式。此外，这种影响的LaX显着缓和性别，与妇女有较低的平均皮质醇水平前LaX，但显着更大的皮质醇水平比所有其他组后LaX.ConclusionsThese结果表明，最近暴露于种族相关的压力可以有一个持续的影响，对非裔美国人的生理压力反应。
BackgroundThe experience of race-related stressors is associated with physiological stress responses. However, much is unknown still about the complex relationship between how race-related stressors are perceived and experienced and potential moderators such as strength of racial identity.PurposeThis research examines the impact of a real-life stressor and strength of race identity on physiological responses to a social evaluative threat induced in the laboratory.MethodsSalivary cortisol measures were collected throughout a stressor protocol. African-American participants were also randomized to one of two conditions designed to promote either racial identification or student identification, before the experimental task. Unexpectedly, a highly publicized real-life racial stressor, the Duke Lacrosse (LaX) scandal, occurred during the course of the data collection. This allowed for pre–post LaX comparisons to be made on cortisol levels.ResultsThese comparisons showed that across both priming conditions, participants post-LaX had highly elevated cortisol levels that were nonresponsive to the experimental stress task, while their pre-LaX counterparts had lower cortisol levels that exhibited a normal stress response pattern. Furthermore, this effect of LaX was significantly moderated by gender, with women having lower mean cortisol levels pre-LaX but significantly greater cortisol levels than all other groups post-LaX.ConclusionsThese results suggest that recent exposure to race-related stress can have a sustained impact on physiological stress responses for African Americans.
