过去的研究已经认识到情绪体验中的文化和性别差异，但这还没有在有效连接的水平上进行研究。为了确定情感体验中有效连接的文化和性别差异，我们将动态因果模型（DCM）应用于中国和美国参与者在观看唤起情感的图像时获得的脑电活动（EEG）测量。相对于美国参与者，中国参与者更喜欢在恐惧与中性体验中具有更完整的背外侧前额叶皮层（dlPFC）的模型。与此同时，相对于男性，女性青睐的模型轴承较少集成dlPFC在恐惧v.中性的经验。还观察到获胜模型的文化-性别相互作用;只有美国参与者表现出性别效应，与其他组相比，美国女性更喜欢具有较低集成dlPFC的模型。这些发现表明，情绪及其神经相关部分取决于个人的文化背景和性别。据我们所知，这也是第一个研究同时应用DCM和EEG的措施，在检查文化，性别互动和情绪。
Past research has recognized culture and gender variation in the experience of emotion, yet this has not been examined on a level of effective connectivity. To determine culture and gender differences in effective connectivity during emotional experiences, we applied dynamic causal modeling (DCM) to electroencephalography (EEG) measures of brain activity obtained from Chinese and American participants while they watched emotion-evoking images. Relative to US participants, Chinese participants favored a model bearing a more integrated dorsolateral prefrontal cortex (dlPFC) during fear v. neutral experiences. Meanwhile, relative to males, females favored a model bearing a less integrated dlPFC during fear v. neutral experiences. A culture-gender interaction for winning models was also observed; only US participants showed an effect of gender, with US females favoring a model bearing a less integrated dlPFC compared to the other groups. These findings suggest that emotion and its neural correlates depend in part on the cultural background and gender of an individual. To our knowledge, this is also the first study to apply both DCM and EEG measures in examining culture-gender interaction and emotion.
