中文摘要： 以往研究指出内感受性对个体的社会认知、情感以及决策加工过程有着重要的影响，并在焦虑形成和发展过程中起着关键作用。但至今，对于焦虑的内感受性的研究明显少于对于焦虑认知成分的探讨，并且内感受性与焦虑的相互关系及其神经机制尚不明确。本项目结合功能磁共振成像技术和多模态整合的方法，试图揭示内感受性与焦虑相互影响的神经机制。研究内容包括：（1）探讨内感受注意与焦虑情绪的神经机制及其异同；（2）揭示内感受性与焦虑的相互作用及其神经机制；（3）结合多模态融合和多变量模式分析的方法，探寻内感受性能力与焦虑情绪体验个体差异的神经机制。通过上述三个方面的研究，有助于我们理解躯体信号与心理加工在焦虑情绪产生中的相互作用机制，通过有效的方式和手段管理和调整我们的身体与心理状态，进而为促进身心健康提供初步的理论基础。

英文摘要： Previous studies revealed that the interoception has great influence on social cognition, emotion and decision making processes and that it plays a fundamental role in the formation and development of anxiety. However, until now, the researches concerning the interoception of anxiety were far more less than the studies investigated the cognitive element of anxiety and the interaction between the interoception and the anxiety and its neural mechanism remain unclear. This project, combining the functional magnetic resonance imaging (fMRI) and integration of multimode approaches, tries to illustrate the neural mechanism underlying the interaction between the interoception and the anxiety. The contents of this project including: (1) Investigation of the common and distinct neural mechanism of attention of interoception and anxiety; (2) Understanding of the neural mechanism underlying the interaction between the interoception and the anxiety; (3) Examination of neural mechanism of individual difference of interoception’s ability and anxiety, using the combination of multimode approaches and multivariable analysis. By the researches mentioned above, we can get valuable understanding into the role of interactional mechanism between somatic signals and psychological activities in the formation of anxiety and how to regulate and adjust our physical and mental state by more effective methods, providing preliminary theoretical foundations for the improvement of physical and mental health.
