在全球化加剧的今天，文化与文化之间的交流日益频繁，人们有更多的机会接触到其他文化，并与其他文化中的个体进行交流合作。多元文化经验丰富了生活的同时，也造成了认知负担，可能引起一系列负面效应。多元文化经验的普遍性和两面性突显了对其进行合理管理和灵活应用能力的重要性。然而，现有的文化能力的理论大多在全球化早期提出，已经无法满足全球化带来的新的变化。为了加深对这一领域的理解，本课题在文化会聚主义理论框架下，将文化视为动态发展的系统，构建以元知识为核心的多元文化能力模型。引入心理学实验的方法，结合文化启动、内隐联系测验、决策博弈等方法，检验多元文化能力运用在跨文化合作情境中的效用与机制。本课题有助于丰富全球化理论，为全球化理论提供科学实证支持，为全球化环境中个人与组织开展跨文化交流与合作的实践提供理论指导。

With the advent of globalization, different cultures have become increasingly connected, and people from different cultures have more opportunities to interact and collaborate. Multicultural experience is a double-edged sword. It could provide ample cultural resources, help open minds and foster receptiveness to foreign cultures; meanwhile, it could also increase intergroup threat, add cognition load, and further lead to negative emotions and resistant responses. The complex influences of multicultural experience highlight the importance of the ability to manage properly and deploy flexibly of context-appropriate cultural knowledge, i.e., multicultural competence. However, most of the existing theories on cultural competence were proposed in the early period of globalization, unable to meet the new challenges brought about by globalization. To shed light on the key elements to improve intercultural effectiveness, our project reconstructed multicultural competence from the perspective of polyculturalism (i.e., emphasizing the hybridity of culture), and proposed the central role mate-knowledge (i.e., the knowledge of cultural knowledge) play in improving intercultural effectiveness. We developed a line of studies to examine the new model of multicultural competence, test its role in cross-cultural collaboration, and recover its underlying mechanism. Through these studies, this project hopes to deepen the understanding of globalization, help people better cope with globalization issues, and provide theoretical guidance for cross-cultural collaboration in a global environment.
