Mental Arithmetic Really Makes Me Tense and Studies Demonstrate This

When I was asked to deliver an unprepared five-minute speech and then subtract sequentially in intervals of 17 – while facing a trio of unknown individuals – the acute stress was evident in my expression.

This occurred since psychologists were filming this quite daunting scenario for a research project that is examining tension using thermal cameras.

Tension changes the blood distribution in the countenance, and scientists have discovered that the cooling effect of a subject's face can be used as a gauge of anxiety and to monitor recovery.

Thermal imaging, based on researcher findings leading the investigation could be a "revolutionary development" in anxiety studies.

The Scientific Tension Assessment

The research anxiety evaluation that I subjected myself to is precisely structured and intentionally created to be an discomforting experience. I visited the university with little knowledge what I was about to experience.

To begin, I was instructed to position myself, relax and listen to white noise through a pair of earphones.

Thus far, quite relaxing.

Subsequently, the scientist who was overseeing the assessment introduced a panel of three strangers into the space. They all stared at me silently as the researcher informed that I now had 180 seconds to develop a brief presentation about my "dream job".

As I felt the warmth build around my collar area, the researchers recorded my face changing colour through their thermal camera. My facial temperature immediately decreased in warmth – turning blue on the infrared display – as I considered how to manage this unplanned presentation.

Research Findings

The researchers have performed this same stress test on numerous subjects. In every case, they saw their nose cool down by several degrees.

My facial temperature decreased in heat by a small amount, as my nervous system redirected circulation from my face and to my visual and auditory organs – a physiological adaptation to help me to look and listen for hazards.

The majority of subjects, like me, recovered quickly; their facial temperatures rose to baseline measurements within a few minutes.

Head scientist explained that being a media professional has probably made me "quite habituated to being placed in stressful positions".

"You are used to the recording equipment and talking with unknown individuals, so you're probably somewhat resistant to public speaking anxieties," the researcher noted.

"But even someone like you, trained to be anxiety-provoking scenarios, demonstrates a physiological circulation change, so this indicates this 'nose temperature drop' is a robust marker of a shifting anxiety level."

Tension Regulation Possibilities

Anxiety is natural. But this revelation, the researchers state, could be used to aid in regulating harmful levels of stress.

"The duration it takes a person to return to normal from this cooling effect could be an objective measure of how efficiently a person manages their stress," said the head scientist.

"If they bounce back remarkably delayed, might this suggest a risk marker of psychological issues? Could this be a factor that we can address?"

As this approach is non-intrusive and monitors physiological changes, it could furthermore be beneficial to track anxiety in infants or in those with communication challenges.

The Mental Arithmetic Challenge

The subsequent challenge in my tension measurement was, personally, more difficult than the first. I was instructed to subtract in reverse starting from 2023 in intervals of 17. One of the observers of expressionless people stopped me every time I committed an error and instructed me to start again.

I acknowledge, I am inexperienced in mental arithmetic.

During the uncomfortable period trying to force my thinking to accomplish mathematical calculations, the only thought was that I wished to leave the increasingly stuffy room.

In the course of the investigation, only one of the 29 volunteers for the stress test did truly seek to depart. The rest, similar to myself, accomplished their challenges – likely experiencing different levels of embarrassment – and were compensated by another calming session of background static through earphones at the end.

Primate Study Extensions

Possibly included in the most surprising aspects of the technique is that, because thermal cameras measure a physical stress response that is inherent within various monkey types, it can furthermore be utilized in non-human apes.

The scientists are actively working on its implementation within habitats for large monkeys, comprising various ape species. They seek to establish how to reduce stress and boost the health of primates that may have been rescued from harmful environments.

Researchers have previously discovered that displaying to grown apes video footage of infant chimps has a relaxing impact. When the scientists installed a visual device close to the rehabilitated primates' habitat, they saw the noses of animals that watched the content heat up.

Therefore, regarding anxiety, viewing infant primates interacting is the contrary to a unexpected employment assessment or an on-the-spot subtraction task.

Potential Uses

Employing infrared imaging in monkey habitats could prove to be valuable in helping rehabilitated creatures to become comfortable to a different community and strange surroundings.
