摘要 西方和东亚文化中的自我构念存在差异,西方自我更强调以自我为中心的关注,而东亚自我则更强调人与人之间的基本社会联系。为了调查自我相关处理中的这种文化差异是否延伸到面部识别,我们记录了英国和中国受试者在判断自己的面部或视觉显示中熟悉的面部的头部方向时的事件相关电位。对于英国人来说,相对于熟悉的面孔,自己的面孔在 280-340 毫秒的额叶中央区域 (N2) 引起了更快的反应和更大的负面活动。相比之下,中国人在行为反应上表现出自我优势减弱,与熟悉的面孔相比,对自己面孔的前N2振幅减小。我们的研究结果表明,在西方和中国文化中,个人面孔的社会显着性增强会导致不同的自我识别神经认知过程。
Abstract Self-construals are different between Western and East Asian cultures in that the Western self emphasizes self-focused attention more, whereas the East Asian self stresses the fundamental social connections between people more. To investigate whether such cultural difference in self-related processing extends to face recognition, we recorded event-related potentials from British and Chinese subjects while they judged head orientations of their own face or a familiar face in visual displays. For the British, the own-face induced faster responses and a larger negative activity at 280–340 ms over the frontal-central area (N2) relative to the familiar face. In contrast, the Chinese showed weakened self-advantage in behavioral responses and reduced anterior N2 amplitude to the own-face compared with the familiar face. Our findings suggest that enhanced social salience of one's own face results in different neurocognitive processes of self-recognition in Western and Chinese cultures.
