More lies, more white matter.A team of researchers from the University of Southern California (USA) discovered a few years ago that the structure of thecompulsive liars brainit is different from that of the honest. Specifically, American researchers have found that compulsive liars have more white matter than gray matter in the frontal lobe of the brain, around 22% more. In other words, the more ‘wired’ a subject has the prefrontal lobe, the greater the facility it has to lie, as disclosed inThe British Journal of Psiquiatry.
Temperature changes in the face.When a person lies there is a ‘Pinocchio effect’, due to which the temperature of the tip of their nose increases or decreases. It also increases your body temperature in the area of the orbital muscle, in the inner corner of the eye, according to research carried out by the University of Granda with the help of thermography, a technique based on the detection of body temperature. When do we say hoaxes? According to a work released inPsychological Science, people are more predisposed to lie when they act very quickly and with little time. When they have more time to reflect, however, he greatly restricts the amount of lies in his speech and is reluctant to deceive. As the authors conclude, it is best not to pressure a person we want to be sincere.
The eyes do deceive.Although there is a widespread belief that the movement of a person’s eyes can reveal if they are lying, and specifically that the movement of the eyes to the right while communicating indicates dishonesty, a study published recently inPLoS ONEreveals that this idea is unfounded. According to Caroline Watt of the University of Edinburgh, the idea is unfounded and has been disproved by her experiments.
Insane lies.Telling the truth improves people’s physical and mental health, according to a study titled “Science of Honesty” and released at the latest Annual Convention of the American Psychological Association. On average, an American is estimated to lie 11 times each week. In experiments with more than a hundred people, Antita E. Kelly and her colleagues at the University of Notre Dame found that if they were asked to reduce the number of lies, after ten weeks their physical and mental health had improved markedly.
The stomach detects lies.Changes in gastric physiology could provide a better method than classic polygraphs to distinguish who is lying from who is telling the truth, according to a University of Texas study that has identified a direct link between the actor’s lying and increased arrhythmias gastric. The scientists simultaneously used electrocardiograms (for the heart) and electrogastrograms (for the stomach).
