“Lying your nose will grow longer!” Many parents will tell their children about the story of the classic fairy tale Pinocchio, but the international academic journal Journal of Investigative Psychology and Offender Profiling published the latest research at the University of Granada, Spain. It is pointed out that when humans lie, the nose will not only grow longer, but will shrink.
The Universidad de Granada (UGR) Center for Brain, Behavior and Spiritual Research (Centro de Mente, Cerebro y Comportamiento, CIMCYC) has announced the development of cutting-edge lie detection technology with an accuracy of 80%, compared to any existing one. The lie detector should be accurate.
In order to verify the “puppet nose effect”, the research team developed a new lie detector using thermal imaging technology. The 60 students were used to observe the changes in body temperature when they lie. The result was that “the nose does not become longer when humans lie, but instead becomes Short, but this change is quite subtle and cannot be seen with the naked eye;
The study also found that when humans lie, the tip temperature drops by about 0.6 to 1.2 degrees Celsius, and the forehead temperature increases by 0.6 to 1.5 degrees. The greater the difference between the tip temperature and the frontal temperature, the more likely the subject is lying. high.
Emilio Gómez, who led the study, pointed out that when lying, the thoughts become complicated, causing the temperature to rise; the increase in restlessness can lead to a drop in nasal temperature. “This lie detection technique can effectively reduce other The error caused by the polygraph instrument can be accurately used in the process of arresting suspects one day.”
