Pinocchio Effects, Your Nose Shows When You Lie

Almost like an elongated Pinocchio nose when the wooden puppet lie, your nose is indeed able to reveal whether or not you're lying. Of course, your nose does not grow long like the fairy tale character, but get hot.

The results of a research psychologist at the University of Granada in Spain that uses thermography to study the temperature of people's faces. They found a temperature spike around the nose and the orbital muscles on the inside of the eye when the person is lying. They also found that the temperature fell face when someone is doing a difficult mental task, and go up when people experience high anxiety.

The Research conducted by Emilio Gomez Milan and Elvira Salazar Lopez revealed that the effect is related to the activity of the insula, a brain region involved in the awareness, detection and regulation of body temperature. "Lying increases the activity in the region," the researchers wrote.

This new work focused so-called "Pinocchio effect" was the part of a doctoral thesis and has yet to be published in a scientific peer-reviewed journal.

Thermography can be used to study the physiological or emotional state as expressed in the temperature of the body, such as sexual desire that heats the chest and genital parts.

Empathy also cause the same effect. Researchers say, when people with high empathy arm saw someone electrocuted, they also experienced a rise in temperature in their arms as if to feel the pain that is experienced by others.

Thermography is a technique based on body temperature and was developed by the United States during World War II for night vision and detect enemies. This technique has been applied in many fields, such as industrial development and treatment. Thermograph cameras have a variety of functions, from measuring the energy lost in the building to indicate respiratory disease in cattle, or rabies in raccoons. *** [LIVESCIENCE | KORAN TEMPO 4075]
