愤怒被认为是一种独特的高公开和接近相关的负面情绪。特质愤怒中个体差异对视觉刺激处理的影响与有关情绪处理的问题有关，还有待探索。使用功能性磁共振成像（fMRI），我们探索了对标准化图像的神经反应，与具有较高性质的愤怒的男性相比，基于价和低愤怒得分的男性的价值和唤醒等级选择（对照）。结果表明，左侧属性腹侧额叶关注网络的激活增加，对高性状愤怒的人的不愉快图像。在左丘脑/pulvinar中，还通过唤醒相互作用进行了一组，因此与对照组相比，具有高性状愤怒的个体增加了对高剧调（与低唤醒）不愉快图像的激活。因此，男性特质愤怒中的个体差异与在处理不愉快的情绪刺激过程中，尤其是高唤醒图像的处理过程中的执行注意力和感觉整合有关。
Anger is considered a unique high-arousal and approach-related negative emotion. The influence of individual differences in trait anger on the processing of visual stimuli is relevant to questions about emotional processing and remains to be explored. Using functional magnetic resonance imaging (fMRI), we explored the neural responses to standardized images, selected based on valence and arousal ratings in a group of men with high trait anger compared to those with normative to low anger scores (controls). Results show increased activation in the left-lateralized ventral fronto-parietal attention network to unpleasant images by individuals with high trait anger. There was also a group by arousal interaction in the left thalamus/pulvinar such that individuals with high trait anger had increased pulvinar activation to the high-arousal (versus low arousal) unpleasant images as compared to controls. Thus, individual differences in trait anger in men are associated with brain regions subserving executive attentional and sensory integration during the processing of unpleasant emotional stimuli, particularly to high arousal images.
