我们通过呈现带有高兴或愤怒韵律的积极和消极的单词，研究了男性和女性参与情绪语音处理的大脑区域。因此，情感韵律和词价要么是一致的，要么是不一致的。我们假设，一致和不一致呈现之间的fRMI对比将揭示调节情绪韵律和词价交互作用的结构。与一致性试验相比，不一致性试验中左额下回(IFG)的激活程度更高。女性IFG活性的这种差异明显大于男性。此外，这种一致性效应在女性中非常显著，而这只在男性中出现了一种趋势。由于左脑IFG多次参与语义加工，这些发现被认为是女性的语义加工比男性更容易受到情绪韵律的影响的证据。此外，目前的数据表明，左侧IFG调节了由于情感韵律和词价之间的不一致而造成的语义加工需求的增加。(C)2004 Elsevier Inc.保留所有权利。
We investigated the brain regions that mediate the processing of emotional speech in men and women by presenting positive and negative words that were spoken with happy or angry prosody. Hence, emotional prosody and word valence were either congruous or incongruous. We assumed that an fRMI contrast between congruous and incongruous presentations would reveal the structures that mediate the interaction of emotional prosody and word valence. The left inferior frontal gyros (IFG) was more strongly activated in incongruous as compared to congruous trials. This difference in IFG activity was significantly larger in women than in men. Moreover, the congruence effect was significant in women whereas it only appeared as a tendency in men. As the left IFG has been repeatedly implicated in semantic processing, these findings are taken as evidence that semantic processing in women is more susceptible to influences from emotional prosody than is semantic processing in men. Moreover, the present data suggest that the left IFG mediates increased semantic processing demands imposed by an incongruence between emotional prosody and word valence. (C) 2004 Elsevier Inc.
