With the development of the society progress, relationships and interpersonal interaction are more and more important to the people on production and living. Interpersonal trust is an important part of interpersonal communication, so the study of interpersonal trust has become a hot spot. DeBruine(2002) considers that compared with unfamiliar faces, individuals tend to trust those with similar to their own face. Stirrat and Perrett(2010)thinks that individuals usually pay trust judgments according to facial features such as appeal and wide-high rates. He Xiaoli(2011) points out that positive emotion has cuing effect to interpersonal trust. Bai Xiaowei(2013) points out that there is significant interaction between the clarity of the emotional reasons and the emotion in the trust judgment. Most studies manifest that Facial attractiveness and facial features provide rich information for interpersonal communication and trust, and emotion is one of the important factors that affects the interpersonal communication and trust.Throughout the past research, the study of interpersonal trust on facial attractiveness and facial features mainly concentrates in the individual differences about face trust evaluation and interpersonal trust tendency. The issue whether more attractive faces more credible, and the question which facial areas can helps people do trust judgment are less discussed. Meanwhile, in the fast rendering and slow appear cases, consistency of the results in facial trust judgment have less investigation. And the study of emotion and interpersonal trust mainly focus on the emotional definition and positive emotion on trust judgment. The study of differences on the facial attractiveness and emotion on trust judgment has less involved.According to previous research,this research adopts double-factors mixed experimental design. The research contains two experiments, that discusses the problems of interpersonal trust from facial attractiveness, the rendering speed and observer emotion. The first experiment mainly inspect the influence of facial attractiveness and the rendering speed on trust judgment,and further discusses look-at situation on trust judgment. The second experiment mainly inspect the influence of facial attractiveness and observer emotion on trust judgment.The behavior results in the first experience found that facial attractiveness has affected trust judgment significantly. Compared with medium and low appeal, subjects tend to trust high appeal faces. It explains that people exist facial attractiveness preferences. In the cognitive evaluation, people are more inclined to do positive cognitive evaluation to the high appeal faces. While the rendering speed has no significant influence on trust judgment. The inadequate explanation is that appears a visual after-effect phenomena in fast rendering, so the result is in line with slow appear’s one.The eye-movement results in the first experience found that participants on trust judgment mainly focus on eyes and mouse in the facial region, so eyes and mouse can be important cues to trust judgment. Compared with long time, subjects are more focus on mouse in the short time rendering. It declares that people are more interested in mouse, while tend to pay a priority attention to it, and call more psychological resources to it.During short time and long time rendering, the participants’fixation count, first fixation time and first fixation duration time are inconformity, while the last evaluation are conformity. It explains that the speed can affect facial understanding levels, and also affects the distribution of attention and cognitive processing, but do not affect the trust judgment results.The results in the second experience found that observer emotion has an significant influence on trust judgment.Compared with negative emotion, people whose emotion is positive more tend to trust the faces. It claims that emotion can affect person’s cognitive evaluation, and make the individual cognitive progress selective. So the last results are in line with the emotion. At the same time, the results also conform to "expand-shaping theory" to explain the trait of emotion and cognitive.
