Coping with mortality threat, a psychological threat unique to humans and distinct from general emotional distress, is traditionally characterized by immediate suppression and prolonged worldview defense within the framework of the influential terror management theory (TMT). Views regarding the personality-trait concepts for this coping capacity diverge: some favor a broad definition based on general psychological attitudes (e.g., hardiness), while others prefer a narrow definition linked to interpersonal attitudes related to social coalition (e.g., attachment style and self-transcendence).
Using functional MRI, we presented healthy older participants with death-related words and explored correlations between the neural responses to mortality threat and the factor scores of the Power to Live questionnaire, which measures eight resilience-related psychobehavioral traits.
We observed a significant association between the factor score and a neural response only for leadership; individuals with a high leadership score exhibited reduced neural response to mortality salience in the right inferior parietal lobule.
Within the TMT framework, our findings align with the concept of the immediate suppression of death-thought accessibility associated with a secure attachment style, a trait conceptually linked to leadership. These findings highlight the unique role for the narrowly defined social-coalitional trait during the immediate stage of the coping process with mortality salience, in contrast to the broadly defined resilience-related personality traits associated with a prolonged worldview defense process. The deterioration of this coping process could constitute a distinct aspect of psychopathology, separate from dysfunction in general emotion regulation.
应对死亡威胁是人类特有的一种心理威胁,与一般的情绪困扰不同,传统上在有影响力的恐怖管理理论(TMT)框架内,其特征是立即抑制和长期的世界观防御。关于这种应对能力的人格特质概念存在分歧:一些人倾向于基于一般心理态度(如坚韧)的宽泛定义,而另一些人则更喜欢与社会联盟相关的人际态度(如依恋风格和自我超越)的狭义定义。
我们使用功能磁共振成像(fMRI),向健康的老年参与者呈现与死亡相关的词汇,并探讨对死亡威胁的神经反应与“生存力量问卷”的因子得分之间的相关性,该问卷测量八种与复原力相关的心理行为特征。
我们仅观察到因子得分与领导力的神经反应之间存在显著关联;领导力得分高的个体在右下顶叶对死亡显著性的神经反应减弱。
在TMT框架内,我们的研究结果与与安全依恋风格相关的死亡念头可及性立即抑制的概念一致,安全依恋风格是一种在概念上与领导力相关的特质。这些发现突出了狭义定义的社会联盟特质在应对死亡显著性的应对过程的即时阶段所起的独特作用,这与与长期世界观防御过程相关的广义定义的与复原力相关的人格特质形成对比。这种应对过程的恶化可能构成精神病理学的一个独特方面,与一般情绪调节功能障碍不同。
