理解故事需要读者想象人物的认知和情感状态。许多故事的内容令人不快，因为它们经常涉及冲突、骚乱或危机。然而，不愉快的故事可以被喜欢和享受。在这项功能磁共振成像研究中，我们使用参数方法来检查（1）增加故事内容的负价以激活心理化网络（心理的认知和情感理论，ToM）的能力，以及（2）喜欢负价叙事的神经基础。一组80个简短的叙述，从中性到负面的情绪效价。对于每个故事，在预研究中从32名参与者中获得了效价和喜欢的平均评级值，后来作为参数回归纳入fMRI分析。另一组24名参与者被动地在三特斯拉MRI扫描仪中阅读叙述。结果显示，情感心理理论相关的大脑区域越来越负的故事效价更强的参与。那些令人不快但同时又令人喜欢的故事会激活内侧前额叶皮层（mPFC），这可能反映了故事内容的道德探索。进一步的分析表明，在阅读负效价故事的过程中，前额叶皮层参与越多，在与情感心理理论和共情的神经处理相关的其他大脑区域中，可以观察到越多的共激活。
The comprehension of stories requires the reader to imagine the cognitive and affective states of the characters. The content of many stories is unpleasant, as they often deal with conflict, disturbance or crisis. Nevertheless, unpleasant stories can be liked and enjoyed. In this fMRI study, we used a parametric approach to examine (1) the capacity of increasing negative valence of story contents to activate the mentalizing network (cognitive and affective theory of mind, ToM), and (2) the neural substrate of liking negatively valenced narratives. A set of 80 short narratives was compiled, ranging from neutral to negative emotional valence. For each story mean rating values on valence and liking were obtained from a group of 32 participants in a prestudy, and later included as parametric regressors in the fMRI analysis. Another group of 24 participants passively read the narratives in a three Tesla MRI scanner. Results revealed a stronger engagement of affective ToM-related brain areas with increasingly negative story valence. Stories that were unpleasant, but simultaneously liked, engaged the medial prefrontal cortex (mPFC), which might reflect the moral exploration of the story content. Further analysis showed that the more the mPFC becomes engaged during the reading of negatively valenced stories, the more coactivation can be observed in other brain areas related to the neural processing of affective ToM and empathy.
