自恋者对社会评价的敏感性应该会增加他们对评价性压力源的生理反应。然而,很少有研究评估自恋的生理相关性。在这项研究中,参与者完成了评价性实验室压力或非评价性控制任务。皮质醇反应性(下丘脑-垂体-肾上腺(HPA)轴应激反应的标志物)和消极情绪(NA)在应激条件下高于对照条件。然而,男性表现出更大的皮质醇反应,在男性中,更高的自恋分数预示着更大的皮质醇反应和更大的NA增加。自恋是无关的皮质醇反应性和NA的妇女和控制条件。这些发现强调了防御性人格特质对HPA反应的影响,并提出了自恋特质可能影响长期健康结果的途径。
Narcissists' sensitivity to social evaluation should increase their physiological reactivity to evaluative stressors. However, very few studies have assessed the physiological correlates of narcissism. In this study, participants completed an evaluative laboratory stressor or a non-evaluative control task. Cortisol reactivity—a marker of the hypothalamic-pituitary-adrenal (HPA) axis stress response—and negative affect (NA) were higher in the stress versus control condition. However, men showed larger cortisol responses and, among men, higher narcissism scores predicted greater cortisol reactivity and larger increases in NA. Narcissism was unrelated to cortisol reactivity and NA among women and in the control condition. These findings highlight the influence of defensive personality traits on HPA reactivity and suggest a pathway through which narcissistic traits might influence long-term health outcomes.
