我是谁?——人际间多感觉刺激下的识脸错觉

Who am I?——Enfacement Illusion Based on Interpersonal Multisensory Stimulation

识脸错觉是在人际间同步多感觉刺激下将他人面孔感知为自我面孔的一种主观体验。继Tsakiris报告了识脸错觉现象之后,研究者通过选取不同的刺激呈现方式、不同的被试,重点对被试的主观体验、行为反应两个方面进行了考察,并得到了大量新的研究成果;发现年龄、性别及内部敏感性是影响识脸错觉强度的重要因素,右侧颞顶联合区、顶内沟和枕下回的神经活动与被试主观报告的错觉体验强度相关。未来识脸错觉研究应侧重于研究策略的多样化并为生物特征识别中新模态的选择提供理论支持。此外,同步多感觉刺激技术的开发与应用将会对自我新面孔认同训练具有重要意义。

Enfacement illusion is a subjective experience evoked by synchronous, but not asynchronous, interpersonal multisensory stimulation （IMS） between one＇s own and other persons＇ face. Since 2008, when Tsakiris first reported enfacement illusion, researchers began to use various stimulus to examine people＇s experience and behavioral reaction. The age, gender and internal sensitivity had significant influence on the strength of illusional experience. Moreover, activities in the right temporo-parietal junction, intraparietal sulcus, and inferior occipital gyrns had significant correlation with the self-reported strength of the illusory experience. Research findings in enfacement illusion will be valuable for not only the research in multimodal biometrics, but also the research in cognitive reconstruction. Practical implications of the research in enfacement illusion include helping those who with facial damage or experienced plastic cosmetology surgeries to establish new self-face identification. In the future, new techniques should be applied in this field to improve the process of stimulus presentation. Meanwhile, participants from various populations should be involved to improve the research validity.
