• Abstract: Facial temperature, due to its proximity to the brain and the abundance of blood vessels, allows it to respond more sensitively to changes in human brain activity. The temperature change of the face under the lying state was studied by setting up a simulated theft situation and preparing a special scenario to bring in the text, and the temperature change data of the three regions of the subject's face, eyes, forehead and mouth were obtained in the experimental process. After data analysis with the help of SPSS, the law of facial temperature change under the lying state was summarized, and it was concluded that the temperature change in the three regions was the most obvious in the eye, followed by the mouth, and again in the frontal area. Through the calculation and analysis of the data, it is found that there is a significant difference between the temperature change value of the three regions of the suspect group and the temperature change value of the three regions of the third person group. At the same time, although there is no statistically significant difference between the temperature change value of the three regions of the suspect group and the temperature change value of the three regions of the recruitment group, there are still obvious differences from the data, so the suspects, witnesses and unrelated third parties can be identified by this. The above rules can be used for in vitro lie identification, which has certain reference value for the study of in vitro polygraph. 面部温度因其靠近大脑的位置和丰富的血管使其可以较为敏锐地反映人类大脑的活动变化。通过设立模拟盗窃情境和准备专门情景带入文本等方式对谎言状态下面部温度变化展开研究，在实验过程中得到被试面部眼部，额部及口部三区域的温度变化数据。借助SPSS进行数据分析后对谎言状态下面部温度变化的规律进行概括，得出三区域温度变化具有眼部最明显，口部次之，额部再次之的结论。通过数据的计算与分析发现，嫌疑人组三区域温度变化值和第三人组三区域温度变化值相比存在显著差异。同时，嫌疑人组三区域温度变化值和证人组三区域温度变化值相比虽然没有统计学意义上的显著差异，但是从数据上来看仍然存在较为明显的不同，因此可以以此识别嫌疑人、证人和无关第三人。以上规律可用于体外谎言识别，对于研究体外测谎具有一定参考价值。
