When I was asked to give an impromptu brief presentation and then subtract sequentially in steps of 17 – while facing a group of unfamiliar people – the intense pressure was evident in my expression.

This occurred since researchers were filming this quite daunting experience for a research project that is examining tension using infrared imaging.

Tension changes the blood flow in the face, and researchers have found that the drop in temperature of a subject's face can be used as a indicator of tension and to observe restoration.

Thermal imaging, according to the psychologists conducting the research could be a "revolutionary development" in stress research.

The Scientific Tension Assessment

The scientific tension assessment that I participated in is precisely structured and deliberately designed to be an discomforting experience. I came to the research facility with little knowledge what I was about to experience.

To begin, I was asked to sit, relax and experience ambient sound through a pair of earphones.

Up to this point, very peaceful.

Afterward, the investigator who was running the test brought in a panel of three strangers into the area. They all stared at me without speaking as the scientist explained that I now had a brief period to create a brief presentation about my "perfect occupation".

When noticing the heat rise around my collar area, the scientists captured my complexion altering through their infrared device. My nasal area rapidly cooled in warmth – appearing cooler on the heat map – as I considered how to bluster my way through this impromptu speech.

Scientific Results

The scientists have performed this identical tension assessment on 29 volunteers. In all instances, they saw their nose cool down by several degrees.

My nasal area cooled in heat by a small amount, as my nervous system shifted blood distribution from my face and to my sensory systems – a bodily response to assist me in look and listen for hazards.

Most participants, comparable to my experience, returned to normal swiftly; their noses warmed to pre-stressed levels within a short time.

Lead researcher explained that being a journalist and presenter has probably made me "relatively adapted to being placed in stressful positions".

"You are used to the camera and talking with unknown individuals, so you're probably somewhat resistant to interpersonal pressures," the researcher noted.

"However, even individuals such as yourself, accustomed to being stressful situations, exhibits a physiological circulation change, so which implies this 'nose temperature drop' is a reliable indicator of a changing stress state."

Anxiety Control Uses

Stress is part of life. But this revelation, the experts claim, could be used to assist in controlling damaging amounts of stress.

"The period it takes an individual to bounce back from this nasal dip could be an reliable gauge of how efficiently a person manages their anxiety," noted the principal investigator.

"Should they recover exceptionally gradually, might this suggest a potential indicator of psychological issues? Could this be a factor that we can tackle?"

Since this method is non-intrusive and monitors physiological changes, it could also be useful to monitor stress in newborns or in people who can't communicate.

The Mental Arithmetic Challenge

The following evaluation in my tension measurement was, from my perspective, more challenging than the initial one. I was told to calculate backwards from 2023 in steps of 17. One of the observers of three impassive strangers interrupted me every time I calculated incorrectly and asked me to begin anew.

I admit, I am poor with calculating mentally.

As I spent awkward duration striving to push my thinking to accomplish subtraction, my sole consideration was that I wanted to flee the growing uncomfortable space.

Throughout the study, only one of the multiple participants for the tension evaluation did actually ask to exit. The remainder, comparable to my experience, finished their assignments – probably enduring assorted amounts of humiliation – and were compensated by another calming session of background static through earphones at the end.

Animal Research Applications

Perhaps one of the most remarkable features of the technique is that, because thermal cameras measure a physical stress response that is natural to various monkey types, it can additionally be applied in animal primates.

The investigators are presently creating its application in refuges for primates, including chimpanzees and gorillas. They aim to determine how to decrease anxiety and boost the health of animals that may have been rescued from harmful environments.

Researchers have previously discovered that showing adult chimpanzees video footage of baby chimpanzees has a calming effect. When the researchers set up a video screen adjacent to the rescued chimps' enclosure, they noticed the facial regions of creatures that observed the footage increase in temperature.

Consequently, concerning tension, observing young creatures playing is the inverse of a surprise job interview or an on-the-spot subtraction task.

Potential Uses

Using thermal cameras in monkey habitats could turn out to be useful for assisting rehabilitated creatures to adapt and acclimate to a unfamiliar collective and unknown territory.
