Effet Pinocchio : votre nez peut réellement vous trahir lorsque vous mentez

Escrito por

Des chercheurs de l’Université de Grenade, en Espagne, ont démontré qu’il est possible de savoir si quelqu’un ment en mesurant les variations de températures à la pointe de son nez.

A l’instar de Pinocchio, votre nez est un excellent indicateur de mensonges. Toutefois, ce n’est pas la longueur qui varie lorsque vous essayez de tromper votre interlocuteur, mais la température. Une équipe de chercheurs en Psychologie Expérimentale à l’Université de Grenade, en Espagne, ont en effet découvert qu’il est possible de savoir si quelqu’un ment, en le soumettant à une thermographie faciale. Cette technique consiste à détecter, au moyen de caméras spécifiques, les différences de températures entre chaque zone du visage.

Les travaux de recherches, mis en place dans le cadre d’une thèse de doctorat, n’ont pour le moment pas encore fait l’objet d’une publication. Toutefois les résultats sont formels : il existe bel et bien «un effet Pinocchio». Les scientifiques ont en effet observé au niveau de la pointe du nez de leurs sujets une baisse de la température lorsque ceux-ci réalisent un grand effort mental. Au contraire, une crise d’anxiété entraine généralement une augmentation de la température faciale.

Par ailleurs, la zone du muscle orbital dans le coin interne de l’œil s’échauffe lorsque le sujet ment. Résultat : en cas de mensonge, l’image obtenue par thermographie montre un nez atteignant le rouge alors que le reste du visage apparait plus jaune orangé. Selon les chercheurs, cet effet serait lié à l’activité d’une région du cerveau, nommée «insula», impliquée dans la conscience ainsi que la détection et la régularisation de la température corporelle.

En vérité, ce n’est pas la première fois que des scientifiques utilisent la thermographie pour caractériser des états émotionnels chez les patients. D’autres études ont même déjà été menées dans le passé pour détecter des sentiments tels que le désir, l’excitation sexuelle ou encore l’empathie.

Des chercheurs espagnols ont découvert que le nez d’un menteur changeait de température. Tout comme Pinocchio, nous sommes trahis par nos émotions.

Il n’y a pas que Pinocchio qui se laisse trahir par son nez lorsqu’il ment. Des chercheurs de l’Université de Grenade, en Espagne, ont conclu, dans le cadre d’une thèse de doctorat, que les variations de température à la pointe de notre nez pouvaient être un bon indicateur de mensonges.

Your nose said so!

If you thinking of telling a lie, you may want to cover your nose first!

According to reports, researchers from the University of Granada in Spain may have discovered a way to detect when a person is being untruthful by a temperature increase particularly around the nose.

The psychology researchers identified a ‘jump in the temperature’ around the nose and in the inner corner of the eye, CBS News reported.

Using a thermography, which detects emotional or physiological state, the researchers found that a small region in the brain called insula, becomes more active when people tell a lie.

The doctoral thesis, further detected that when people are concentrating, the body temperature drops as opposed to a rise in temperature when they are experiencing high.

Little white lies may be bad for your health

How to be healthy? Exercise, eat your vegetables, and refrain from telling little white lies, according to a new study.

In early findings from the University of Notre Dame in Indiana, US, researchers studied 110 participants who were told to stop telling either major or minor lies for 10 weeks. The control group was given no special instructions about lying.

When those in the no-lie group told three fewer white lies than in other weeks, they complained less of headaches, sore throats, tenseness, anxiety and other problems than those in the control group.

«Recent evidence indicates that Americans average about 11 lies per week,» said lead author Anita E. Kelly in a recent press release.

«We found that the participants could purposefully and dramatically reduce their everyday lies, and that in turn was associated with significantly improved health.»

Kelly presented her research on Saturday at the American Psychological Association’s annual meeting in Orlando, Florida.

Linda Stroh, a professor emeritus of organisational behaviour at Loyola University in Chicago, told USA Today that the findings are similar to her own research on trust.

«When you find that you don’t lie, you have less stress,» she says. «Being very conflicted adds an inordinate amount of stress to your life.»

Some of the ways people refrained from lying in the study included avoiding exaggerating the truth about daily accomplishments and not making false excuses for running late or not finishing tasks.

Your nose knows when you’re lying – research

Escrito por

Your nose gives away when you’re lying – not by growing like Pinocchio’s, but by increasing in temperature, according to a new study.

 

Spanish researchers used thermographic cameras to measure the changes in participants’ body temperature during different emotions.

Emilio Gomez Milan and Elvira Salazar Lopez, from the University of Granada’s Department, found that when a mental effort is made (performing difficult tasks, being interrogated on a specific event or lying) facial temperature changes.

When participants told a fib, researchers found the temperature around the nose and in the orbital muscle in the inner corner of the eye rose.

They dubbed the phenomenon the «Pinocchio effect», after the fictional character whose nose grew whenever he didn’t tell the truth.

When we lie, a brain element called «insula» is activated. The insula is a component of the brain reward system, and only activates when we experience 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 vice-versa,» the researchers said.

When people concentrate, facial temperature drops, while anxiety makes people’s facial temperature go up.

The study also found sexual excitement could be identified in men and women using thermography with temperature increasing in the chest and genitals during arousal.

The researchers also looked at the thermal footprint of aerobic exercise and different dance.

«When a person is dancing flamenco the temperature in their buttocks drops and increases in their forearms. That is the thermal footprint of flamenco, and each dance modality has a specific thermal footprint,» Prof Salazar says.

Liar, Liar, Nose on Fire!

Escrito por

New research from the University of Granada’s Department of Experimental Psychology makes it as plain as the nose on your face: When people lie, their noses get hotter. Nicknamed the «Pinocchio effect,» the phenomenon was observed during a study that applied thermography to psychology to see what the body’s temperature could reveal about the mind.

 

The Heat is On

Developed during World War II for military surveillance, thermography uses special heat-sensitive cameras to detect different temperatures of objects. The images the cameras produce, called thermograms, give a visual representation of the hot and cool areas of a subject. Today, the technology has a wide variety of applications—from medicine to engineering.

The two lead researchers on the project, Emilio Gómez Milán and Elvira Salazar López, have been exploring new applications of thermography to psychology. The pair believes that using heat-sensing cameras can tell us much about the human mind. (Live Science has reported that their research is part of a doctoral dissertation and yet to be published in a peer-reviewed journal.)

You Can’t Hide Your Lying Nose

When the researchers studied the thermograms of their lying subjects, they saw that the temperature around their noses and the inner corners of their eyes increased. The researchers believe that lying activates a neural region called the insula, a component of the brain involved in reward, emotion, and temperature regulation. When strong emotions are openly expressed, the insula becomes more active, state the researchers.

The team also examined thermograms of subjects in other situations and found intriguing results. Facial temperature drops when performing a tough mental task but rises when during an anxiety attack. Emilio Gómez Milán and Elvira Salazar López claim these temperature changes can be used to assess the physical, mental, and emotional status of the subject. «The thermogram is a somatic marker of subjective or mental states and allows us see what a person is feeling or thinking,» Salazar López states.
