本研究试图扩展对大胆作用的认识，大胆是一种跨诊断的双相情感特征维度，涉及对威胁的低敏感性，在情绪反应和使用生理和基于报告的措施进行调节中的作用。先前的一项研究发现，被动观看令人厌恶的图像时，大胆与晚期积极电位（LPP）降低有关，但在情绪调节期间则不然。还观察到 LPP 和自我报告的反应性之间存在脱节。在这里，参与者（N = 63）完成了一项情绪调节任务，在记录脑电图活动的同时，他们要么被动地观看，要么努力上调或下调他们对愉快、不愉快和中性图片的情绪反应；他们后来回顾性地评估了监管工作的成功程度。检验调节指令和胆量对 LPP 幅度的交互影响的方差分析显示，相对于被动观看，较低的胆量（较高的特质恐惧）与指令下调期间 LPP 对威胁照片的矛盾增加相关，相对于被动观看，以及这些试验中报告的调节成功率较低。出乎意料的是，在整体情感图像，尤其是养育照片中，观察到了类似的 LPP 效应。尽管受到某些限制，这些结果表明，大胆的个体差异不仅在对厌恶刺激的一般反应中发挥作用（如先前的工作所证明的那样），而且在努力下调情绪反应的能力中发挥作用。
The present study sought to extend knowledge of the role of boldness, a transdiagnostic bipolar trait dimension involving low sensitivity to threat, in emotional reactivity and regulation using physiological and report-based measures. One prior study found that boldness was associated with reduced late positive potential (LPP) while passively viewing aversive images, but not during emotion regulation; a disconnect between LPP and self-reported reactivity was also observed. Here, participants (N = 63) completed an emotion regulation task in which they either passively viewed or effortfully up- or downregulated their emotional reactivity to pleasant, unpleasant, and neutral pictures while EEG activity was recorded; they later retrospectively rated the success of their regulation efforts. ANOVAs examining the interactive effects of regulation instruction and boldness on LPP amplitude revealed that lower boldness (higher trait fearfulness) was associated with paradoxical increases in LPP to threat photos during instructed downregulation, relative to passive viewing, along with lower reported regulation success on these trials. Unexpectedly, similar LPP effects were observed for affective images overall, and especially nurturance photos. Although subject to certain limitations, these results suggest that individual differences in boldness play a role not only in general reactivity to aversive stimuli, as evidenced by prior work, but in the ability to effortfully downregulate emotional response.
