Background: Previous studies of face trustworthiness have often examined isolated face stimulus, ignoring the role of context.
Purpose: The current study used mouse-tracking technique and the seven-point Likert scale to examine the effect of emotional visual context on face trustworthiness judgment at the levels of the early evaluation process and final evaluation result.
Methods: Experiment 1 used mouse-tracking technique to study the impact of different contexts on the judgment of face trustworthiness at the early evaluation process. Experiment 2 used the seven-point Likert scale to study the effect of different contexts on the judgment of face trustworthiness at the final evaluation result.
Results: Experiment 1 found that when faces are embedded in threatening negative contexts, the mouse trajectories are more tortuous for trustworthy responses and straighter for untrustworthy responses than in neutral contexts. When faces are embedded in non-threatening negative contexts, the mouse trajectories are more tortuous for trustworthy responses but did not significantly differ for untrustworthy responses than in neutral contexts. When faces are embedded in positive contexts, the mouse trajectories are straighter for trustworthy responses and more tortuous for untrustworthy responses than in neutral contexts. Experiment 2 found that faces embedded in threatening and non-threatening negative contexts have lower scores and faces embedded in positive contexts have higher scores than in neutral contexts.
Conclusion: The results show that the emotional visual context significantly influences the judgment of face trustworthiness both at the levels of the early evaluation process and final evaluation result.

情感视觉背景对人脸可信度判断的影响

背景：以前关于人脸可信度的研究经常检查孤立的人脸刺激，而忽略了背景的作用。
目的：本研究采用鼠标跟踪技术和李克特七点量表从早期评价过程和最终评价结果两个层面考察情感视觉上下文对人脸可信度判断的影响。
方法：实验一采用鼠标跟踪技术，研究早期评价过程中不同情境对人脸可信度判断的影响。实验二采用李克特七点量表研究最终评价结果中不同情境对人脸可信度判断的影响。
结果：实验 1 发现，当面部嵌入威胁性负面环境时，与中性环境相比，鼠标轨迹对于值得信赖的响应更曲折，而对于不可信响应则更直。当面部嵌入非威胁性的负面环境中时，鼠标轨迹对于可信赖的响应更加曲折，但对于不可信的响应与中性环境相比没有显着差异。当面部嵌入到积极的上下文中时，与中立的上下文相比，鼠标轨迹对于可信的响应更直，而对于不可信的响应则更曲折。实验 2 发现，嵌入威胁和非威胁负面上下文的人脸得分较低，而嵌入积极上下文的人脸得分高于中性上下文。
结论：结果表明，情感视觉上下文在早期评价过程和最终评价结果两个层面均显着影响人脸可信度的判断。
