Abstract

We examined the role of the dorsal medial prefrontal cortex (dMPFC) when listening participants are evaluating a speaker's pleasant or unpleasant mental state and also judging their own pleasant or unpleasant mental state through event-related functional magnetic resonance imaging (fMRI) analysis. The speech materials were linguistically positive and negative short phrases uttered in a pleasant or unpleasant emotional tone (i.e. affective prosody) . The brain imaging results show that the dMPFC is commonly activated in both the listener's own and the speaker's mind evaluation tasks. Furthermore, the dMPFC activation is significantly stronger when the listener is evaluating his or her own mind than when evaluating the speaker's mind. With respect to reaction time and rate of concordance between the intention of the speaker and the listener's judgment, there was significant interaction between linguistic meaning and affective prosody in both tasks. However, the main effect of affective prosody was significant only in the task evaluating the speaker's mind. These results suggest that the linguistic meaning and affective prosody of utterances interfere with each other to generate coherent interpretation of a speaker's mind.
