The study found when a person tells an untruth, the area around the nose heats up — registering a hotter color in the thermal image. They call this “Pinocchio effect.” According to the university’s website, lying about one’s feelings affects a part of the brain called the insula. It states the insula activates when one experiences “real feelings.” “The insula is involved in the detection and regulation of body temperature. Therefore, there is a strong negative correlation between insula activity and temperature increase: the more active the insule (the greater the feeling) the lower the temperature change, and viceversa,” the researchers stated. They found that lying is not the only thing that will change the temperature in the face but also strong mental exertion, which drops temperature, and anxiety, which raises it. Live Science pointed out this work was performed as part of a doctoral thesis and has yet to be published in a peer-reviewed journal.
