正念是不加评判地关注当下的体验。正念训练可以减少抑郁和焦虑，并影响中线自我参照以及侧化体感和执行网络的神经过程。尽管正念有利于情绪调节，但人们对其与愤怒的关系以及相应的神经相关性知之甚少。这项研究探讨了正念意识与愤怒面部处理的大脑血流动力学之间的关系，以及正念训练的影响。十八名健康志愿者完成了愤怒的面部处理功能磁共振成像范式以及正念和愤怒特征的测量。其中十名参与者是从正念减压 (MBSR) 课程中招募的，并在培训后完成了成像和其他评估。自我报告的正念意识在MBSR后有所增加，但特质愤怒并没有改变。基线正念意识与左顶下小叶对愤怒面孔的激活呈负相关；特质愤怒与右侧额中回和双侧角回呈正相关。没有发现愤怒面部处理的显着前后变化，但特征正念意识和愤怒的变化与旁边缘激活的亚阈值差异相关。这些初步和假设生成的发现表明，分析正念训练对愤怒可能产生的影响可能始于愤怒面部处理的个体差异。
Mindfulness is paying attention, non-judgmentally, to experience in the moment. Mindfulness training reduces depression and anxiety and influences neural processes in midline self-referential and lateralized somatosensory and executive networks. Although mindfulness benefits emotion regulation, less is known about its relationship to anger and the corresponding neural correlates. This study examined the relationship of mindful awareness and brain hemodynamics of angry face processing, and the impact of mindfulness training. Eighteen healthy volunteers completed an angry face processing fMRI paradigm and measurement of mindfulness and anger traits. Ten of these participants were recruited from a Mindfulness-Based Stress Reduction (MBSR) class and also completed imaging and other assessments post-training. Self-reported mindful awareness increased after MBSR, but trait anger did not change. Baseline mindful awareness was negatively related to left inferior parietal lobule activation to angry faces; trait anger was positively related to right middle frontal gyrus and bilateral angular gyrus. No significant pre-post changes in angry face processing were found, but changes in trait mindful awareness and anger were associated with sub-threshold differences in paralimbic activation. These preliminary and hypothesis-generating findings, suggest the analysis of possible impact of mindfulness training on anger may begin with individual differences in angry face processing.
