他人的内在状态可以通过观察他们的行为或倾听他们的声音来理解。虽然行为风格（活力形式）的神经基础已经被研究过了，但没有关于我们如何通过听别人的讲话来识别他们的内部状态的信息。在这里，使用功能磁共振成像技术，我们调查了听觉活力形式的神经相关性，而被试在三种不同的条件下听动作动词：人类的声音发音的动词在粗鲁和温柔的方式，机器人的声音发音相同的动词没有活力形式，和一个混乱的版本相同的动词发音的人的声音。与以往关于活力形式编码的研究相一致，我们发现在听人的声音传达特定的活力形式时，大脑皮层的中央部分会被特定激活。此外，当同时听到人类和机器人的声音时，左额下回的后部和通常被描述为在观察和执行手臂动作期间被激活的顶叶前运动回路都被激活。最后，上级颞回在所有三种情况下都被双侧激活。我们的结论是，中央的一部分是一个关键区域的活力形式处理允许的活力形式的理解，无论他们传达的方式。(C)2016由Elsevier Ltd.出版
The internal state of others can be understood observing their actions or listening to their voice. While the neural bases of action style (vitality forms) have been investigated, there is no information on how we recognize others' internal state by listening to their speech. Here, using fMRI technique, we investigated the neural correlates of auditory vitality forms while participants listened to action verbs in three different conditions: human voice pronouncing the verbs in a rude and gentle way, robot voice pronouncing the same verbs without vitality forms, and a scrambled version of the same verbs pronounced by human voice. In agreement with previous studies on vitality forms encoding, we found specific activation of the central part of insula during listening to human voice conveying specific vitality forms. In addition, when listening both to human and robot voices there was an activation of the posterior part of the left inferior frontal gyrus and of the parieto-premotor circuit typically described to be activated during observation and execution of arm actions. Finally, the superior temporal gyrus was activated bilaterally in all three conditions. We conclude that, the central part of insula is a key region for vitality forms processing allowing the understanding of the vitality forms regardless of the modality by which they are conveyed.
