Elevated neuroticism is associated with increased psychological reactivity to stressors. Research on individual differences and physiological reactivity (e.g., electrodermal activity), however, has focused on clinical samples and measures of basal activity (e.g., nonspecific skin conductance responses) or responses to nonaffective stimuli. Surprisingly, there is a dearth of work on physiological reactivity to emotional stimuli as a function of neuroticism. Thus, the authors sought to examine the relationship between neuroticism and skin conductance reactivity to emotionally evocative pictures in a nonclinical sample. Individuals higher in neuroticism exhibited both greater skin conductance reactivity to emotional (and particularly aversive) pictures as well as more extended reactivity than did emotionally stable individuals. Implications for health are discussed.
神经质水平升高与对应激源的心理反应增强有关。然而，关于个体差异与生理反应性（如皮肤电活动）的研究主要集中在临床样本以及基础活动指标（如非特异性皮肤电导反应）或对非情感性刺激的反应上。令人惊讶的是，关于作为神经质函数的对情绪刺激的生理反应性的研究却很少。因此，作者试图在非临床样本中检验神经质与对唤起情绪的图片的皮肤电导反应性之间的关系。与情绪稳定的个体相比，神经质水平较高的个体对情绪性（尤其是厌恶的）图片表现出更大的皮肤电导反应性，且反应持续时间更长。文中还讨论了其对健康的影响。
