中文摘要： 面孔识别不论对人脑还是对计算机都是一个复杂的信息处理过程，研究内容涉及人工智能、机器视觉、认知科学、神经科学等领域。面孔熟悉度效应是面孔认知研究的重要方向，但目前的相关研究都是在 "意识上"展开的，至今没有"意识下"熟悉度效应的研究。本项目采用改进的双眼竞争范式：连续闪烁抑制CFS(continuous flash suppression)实现对意识上视觉信息的抑制，并利用事件相关电位(ERPs)完成对意识下面孔熟悉效应的研究，进而探讨"面孔认知的熟悉度效应是否依赖于意识？"这一科学问题。本研究一方面对推动意识下认知活动的研究具有重要科学意义；另一方面，开展具体的意识下面孔熟悉度效应认知研究，是对面孔认知研究的必要补充，同时也可以加深对人类智能的认识，促进认知科学在人工智能领域的应用，具有重要的学术价值。还可以将本项目的研究成果应用到测谎中，对国家安全、犯罪调查具有重要的实用价值。

英文摘要： Face recognition is a complicated processing for both brain and computer. The research of face recognition involves Artificial Intelligence, Machine Vision, Cognitive Science and Neuroscience. The research about effects of familiarity on face processing is one of the most important issues on face perception. Event-related potentials (ERPs) studies have shown that faces give rise to a negative wave approximately 170 ms after stimulus onset, and the familiarity of face could affect the ERPs. Most of the researches of face familiarity were conducted on conscious condition, and few reports were about the unconscious condition. In our research, a new paradigm for unconscious visual research: continuous flash suppression (CFS) was used. By recording ERPs during the experiment, the effects of familiarity on unconscious face processing will be studied. The aim of our study is investigate whether the perception of familiar face depend on consciousness? Our research is valuable for the researches about the perception of unconscious visual stimuli, especially the familiarity effects of face perception. Furthermore, our study helps understanding the human intelligence and utilizing in artificial intelligence. On the other hand, the finding of our research can be used in the lie detector, which is valuable for the national s
