理解言语中的情感韵律是人类社会生活的重要功能。然而，在日常交际中，情感韵律和语义内容中的冲突信息同时出现的现象很普遍。在这里，我们试图指定参与这些干扰沟通渠道的冲突监控的大脑区域。通过功能磁共振成像技术，我们观察到当被试听不一致的句子时，右侧背侧前扣带皮层、右侧上级颞回（STG）和上级颞沟的信号增强。此外，价特异性效应被发现在左额下回和左STG愉快地吟诵的句子表示一个负面的内容。当愤怒地吟诵的句子与积极的语义内容相结合时，左尾状核沿着丘脑是活跃的。我们的研究结果表明，大脑网络，监测冲突的情绪韵律和情绪语义内容组成的内侧前额叶区域，以前与认知冲突处理。此外，我们的研究扩展了这些过程的知识，提出具体的情绪冲突处理的效价差异。
To comprehend emotional prosodic cues in speech is a critical function of human social life. However, it is common in everyday communication that conflicting information in emotional prosody and semantic content co-occur. Here, we sought to specify brain regions involved in conflict monitoring of these interfering communication channels. By means of functional magnetic resonance imaging, we obtained signal increases in the right dorsal anterior cingulate cortex and right superior temporal gyrus (STG) and superior temporal sulcus when participants listened to incongruous compared with congruous sentences. Moreover, valence-specific effects were found in the left inferior frontal gyrus and left STG for happily intoned sentences expressing a negative content. The left caudate nucleus along with the thalamus was active when angrily intoned sentences were coupled with positive semantic content. Our results suggest a brain network that monitors conflict in emotional prosody and emotional semantic content comprising of medial prefrontal areas that have previously been associated with cognitive conflict processing. Furthermore, our study extends the knowledge of these processes by suggesting valence-specific differences of emotional conflict processing.
