面孔识别的眼动研究

The Eye Movement Research of Facial Recognition

采用眼动记录法探讨面孔识别的加工过程。在实验一中,通过记录被试识别面孔图片和非面孔图片时的即时加工过程,考查被试在知觉面孔与一般物体时的眼动差异。在实验二中,考察被试在知觉熟悉面孔与陌生面孔时的眼动差异与时间进程的差异。结果表明:(1)个体在加工面孔时倾向于首先在双眼间平移而后向嘴巴运动,完成面孔识别,而在识别物体图片时则没有固定的运动轨迹。(2)在知觉熟悉面孔时被试倾向于只注视眼睛,而在知觉陌生面孔图片时则与实验一的面孔图片眼动轨迹相似。

This article is about an analysis of eye movement in facial recognition. In experiment 1, we record the process of subjects in identifying the facial pictures and the non-facial pictures to examine the difference of eye movement. In experiment 2, we ex amined the difference of eye movement trace in pro- cessing familiar faces and unfamiliar faces. We can make consequences that when people process facial pictures they prefer to firstly search the eyes and then move to the mouth while when they process non-facial pictures their eye movement trace is unexpected. When people process familiar faces they prefer to take a look at the eyes while process unfamiliar faces their eye movement trace is as same as the experiment 1.
