This study aimed to investigate emotional alterations in a community sample with primary psychopathic traits. Sixty males selected from a larger sample and divided in two groups, High (HP) and Low (LP) primary Psychopathy, watched 15 validated emotional movies divided in five categories (Erotic, Neutral, Fear, and the new Scenery and Compassion). Subjective responses and cortical activity in the EEG Gamma band (30–49 Hz) were recorded. Concerning self-reports, HP participants felt less anxious and anguished in response to Fear clips and less sad, touched and anguished by Compassion excerpts. Negative clips induced larger EEG Gamma activity in both groups compared to neutral and erotic movies, but Gamma activity to Fear movies was reduced in HP. This group showed also a small cortical response to positive Scenery movies, at the level of the Neutral ones. Source analysis showed in HP participants a reduced cortical activation to Fear in a large brain network, comprising the right prefrontal and temporal cortices and bilateral inferior parietal cortex. Results showed that primary psychopathy, in addition to the impaired response to Fear, was associated with a reduced response also to other specific categories of emotional stimuli, suggesting an altered affect on a broader scale.

这项研究旨在调查具有主要精神病性状的社区样本中的情绪变化。从较大样本中选出的60位男性分为两组，分别是高（HP）和低（LP）原发性精神病，他们观看了15部经过验证的情感电影，分为五个类别（色情，中性，恐惧以及新风光和同情心）。记录EEG伽马波段（30–49 Hz）中的主观反应和皮层活动。关于自我报告，HP参与者对Fear短片的反应减少了焦虑和烦恼，同情节的摘要也减少了悲伤，感动和烦恼。与中性和色情电影相比，阴性片段在两组中均诱发了较大的EEGγ活性，但在HP中，Fear电影的Gamma活性降低。这个小组也对正面的风景电影表现出了小的皮质反应，在中立的水平。资料来源分析显示，HP参与者在包括右前额叶和颞叶皮质以及双侧下顶叶皮质在内的大型大脑网络中，皮层对Fear的激活减少。结果表明，除了对恐惧的反应减弱外，原发性精神病还与对其他特定类别的情绪刺激的反应减弱有关，这表明影响范围更广。
