人类的杏仁核会强烈地激活恐惧面孔。对恐惧面孔的强烈反应被认为反映了杏仁核作为一种早期预警机制的适应功能。虽然文化塑造了情感和社会经验的几个方面，包括如何感知恐惧并向他人表达恐惧，但我们对文化如何影响对恐惧刺激的神经反应知之甚少。在这里，我们发现双侧杏仁核对恐惧面孔的反应是由文化调节的。我们使用功能性磁共振成像来测量两种不同文化中杏仁核对恐惧和非恐惧面孔的反应。日本本土的日本人和美国的白种人对自己文化群体成员表达的恐惧表现出更大的杏仁核激活。这一发现为自动神经反应中的文化调节提供了新颖而令人惊讶的证据。
The human amygdala robustly activates to fear faces. Heightened response to fear faces is thought to reflect the amygdala's adaptive function as an early warning mechanism. Although culture shapes several facets of emotional and social experience, including how fear is perceived and expressed to others, very little is known about how culture influences neural responses to fear stimuli. Here we show that the bilateral amygdala response to fear faces is modulated by culture. We used functional magnetic resonance imaging to measure amygdala response to fear and nonfear faces in two distinct cultures. Native Japanese in Japan and Caucasians in the United States showed greater amygdala activation to fear expressed by members of their own cultural group. This finding provides novel and surprising evidence of cultural tuning in an automatic neural response.
