When I was asked to deliver an unprepared short talk and then subtract sequentially in steps of 17 – while facing a panel of three strangers – the intense pressure was evident in my expression.

This occurred since scientists were filming this somewhat terrifying scenario for a research project that is studying stress using infrared imaging.

Stress alters the circulation in the countenance, and experts have determined that the cooling effect of a subject's face can be used as a measure of stress levels and to monitor recovery.

Infrared technology, according to the psychologists conducting the research could be a "revolutionary development" in anxiety studies.

The Experimental Stress Test

The scientific tension assessment that I participated in is precisely structured and deliberately designed to be an unexpected challenge. I came to the academic institution with little knowledge what I was in for.

First, I was instructed to position myself, calm down and hear ambient sound through a audio headset.

Thus far, quite relaxing.

Then, the scientist who was conducting the experiment introduced a trio of unknown individuals into the area. They all stared at me silently as the researcher informed that I now had 180 seconds to create a five minute speech about my "ideal career".

When noticing the warmth build around my collar area, the researchers recorded my complexion altering through their infrared device. My nose quickly dropped in temperature – appearing cooler on the infrared display – as I considered how to navigate this unplanned presentation.

Scientific Results

The investigators have conducted this same stress test on 29 volunteers. In all instances, they observed the nasal area decrease in warmth by a noticeable amount.

My nose dropped in temperature by a small amount, as my nervous system redirected circulation from my nasal region and to my eyes and ears – a physiological adaptation to help me to observe and hear for danger.

Nearly all volunteers, like me, returned to normal swiftly; their nasal areas heated to pre-stressed levels within a short time.

Principal investigator stated that being a reporter and broadcaster has probably made me "relatively adapted to being placed in tense situations".

"You're accustomed to the camera and speaking to unknown individuals, so you're probably quite resilient to social stressors," the researcher noted.

"Nevertheless, even people with your background, experienced in handling stressful situations, demonstrates a biological blood flow shift, so that suggests this 'facial cooling' is a robust marker of a changing stress state."

Stress Management Applications

Tension is inevitable. But this discovery, the scientists say, could be used to aid in regulating harmful levels of tension.

"The period it takes someone to recover from this nasal dip could be an reliable gauge of how effectively a person manages their tension," said the principal investigator.

"If they bounce back unusually slowly, might this suggest a risk marker of anxiety or depression? Is this an aspect that we can tackle?"

Because this technique is without physical contact and measures a physical response, it could furthermore be beneficial to observe tension in infants or in those with communication challenges.

The Calculation Anxiety Assessment

The subsequent challenge in my anxiety evaluation was, personally, even worse than the opening task. I was instructed to subtract sequentially decreasing from 2023 in increments of seventeen. Someone on the panel of three impassive strangers halted my progress each instance I calculated incorrectly and told me to start again.

I admit, I am inexperienced in calculating mentally.

While I used awkward duration attempting to compel my mind to execute mathematical calculations, all I could think was that I desired to escape the growing uncomfortable space.

In the course of the investigation, merely one of the multiple participants for the tension evaluation did truly seek to leave. The rest, similar to myself, accomplished their challenges – presumably feeling assorted amounts of embarrassment – and were given an additional relaxation period of background static through headphones at the conclusion.

Non-Human Applications

Maybe among the most unexpected elements of the method is that, since infrared imaging record biological tension reactions that is natural to various monkey types, it can also be used in other species.

The scientists are currently developing its use in habitats for large monkeys, comprising various ape species. They seek to establish how to decrease anxiety and enhance the welfare of creatures that may have been removed from distressing situations.

Researchers have previously discovered that presenting mature chimps recorded material of young primates has a relaxing impact. When the investigators placed a video screen near the protected apes' living area, they observed the nasal areas of primates that viewed the content heat up.

Therefore, regarding anxiety, observing young creatures engaging in activities is the inverse of a unexpected employment assessment or an spontaneous calculation test.

Potential Uses

Employing infrared imaging in monkey habitats could prove to be useful for assisting protected primates to become comfortable to a different community and unfamiliar environment.
