中文摘要：

社会认知神经科学是运用认知神经科学的研究手段，探讨社会科学问题与理论的多学科交叉领域。近来，功能性近红外光学成像技术（functional near-infrared spectroscopy,fNIRS）凭借生态效度高、成像安全、对头动耐受性高、成本低等优势，成为了该领域新兴的热点技术。无论是在婴儿发育和社会经济决策的单脑研究中，还是在人际互动的多脑研究中，它都有广泛应用。未来近红外光学成像的应用可以向多脑神经反馈、脑机接口技术、设备无线化和多模态成像做进一步探索。

英文摘要：

Social cognitive neuroscience is an interdisciplinary field that explores the theory and practice of social science with cognitive neuroscience research methods. Recently, functional near-infrared spectroscopy （fNIRS） has become a hot technique used in social cognitive neuroscience for its advantage of high ecological validity, image security, high reliability and low cost. Currently, fNIRS is widely used in single brain research studying the neural mechanism of infant development, social economic decision- making and interpersonal interaction. In the future, it could be a very useful imaging tool in multi-brain research including neurofeedback, brain-computer interface, wireless equipment and multi-modality imaging.
