Mental Arithmetic Truly Causes Me Anxiety and Research Confirms It

After being requested to deliver an unprepared five-minute speech and then subtract sequentially in steps of 17 – while facing a group of unfamiliar people – the intense pressure was evident in my expression.

That is because scientists were filming this somewhat terrifying experience for a investigation that is analyzing anxiety using heat-sensing technology.

Stress alters the blood flow 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.

Heat mapping, according to the psychologists behind the study could be a "revolutionary development" in stress research.

The Scientific Tension Assessment

The research anxiety evaluation that I underwent is carefully controlled and purposely arranged to be an unexpected challenge. I arrived at the academic institution with no idea what I was facing.

First, I was asked to sit, relax and listen to white noise through a set of headphones.

Up to this point, very peaceful.

Afterward, the scientist who was overseeing the assessment invited a panel of three strangers into the area. They collectively gazed at me without speaking as the investigator stated that I now had three minutes to prepare a brief presentation about my "ideal career".

While experiencing the temperature increase around my collar area, the experts documented my skin tone shifting through their infrared device. My nose quickly dropped in heat – turning blue on the infrared display – as I thought about how to navigate this unplanned presentation.

Research Findings

The scientists have performed this identical tension assessment on numerous subjects. In all instances, they noticed the facial region dip in temperature by between three and six degrees.

My facial temperature decreased in warmth by a couple of degrees, as my biological response system pushed blood flow away from my face and to my visual and auditory organs – a physiological adaptation to enable me to look and listen for danger.

Nearly all volunteers, similar to myself, bounced back rapidly; their nasal areas heated to normal readings within a brief period.

Principal investigator noted that being a journalist and presenter has probably made me "quite habituated to being subjected to anxiety-provoking circumstances".

"You are used to the filming device and speaking to unfamiliar people, so you're probably quite resilient to public speaking anxieties," the researcher noted.

"Nevertheless, even people with your background, experienced in handling anxiety-provoking scenarios, shows a bodily response alteration, so that suggests this 'nasal dip' is a consistent measure of a changing stress state."

Anxiety Control Uses

Stress is part of life. But this finding, the experts claim, could be used to assist in controlling harmful levels of stress.

"The duration it takes a person to return to normal from this temperature drop could be an reliable gauge of how effectively somebody regulates their anxiety," said the lead researcher.

"When they return unusually slowly, might this suggest a risk marker of psychological issues? Is this an aspect that we can tackle?"

Because this technique is non-invasive and records biological reactions, it could additionally prove valuable to observe tension in infants or in people who can't communicate.

The Mental Arithmetic Challenge

The second task in my anxiety evaluation was, from my perspective, more challenging than the initial one. I was asked to count sequentially decreasing from 2023 in intervals of 17. A member of the group of three impassive strangers interrupted me whenever I made a mistake and told me to recommence.

I acknowledge, I am bad at mental arithmetic.

As I spent uncomfortable period attempting to compel my mind to execute subtraction, all I could think was that I desired to escape the growing uncomfortable space.

During the research, just a single of the multiple participants for the stress test did genuinely request to depart. The remainder, comparable to my experience, accomplished their challenges – likely experiencing assorted amounts of embarrassment – and were compensated by another calming session of background static through audio devices at the finish.

Animal Research Applications

Possibly included in the most surprising aspects of the technique is that, as heat-sensing technology measure a physical stress response that is inherent within numerous ape species, it can also be used in animal primates.

The researchers are actively working on its use in sanctuaries for great apes, comprising various ape species. They aim to determine how to lower tension and enhance the welfare of creatures that may have been removed from harmful environments.

The team has already found that presenting mature chimps recorded material of young primates has a relaxing impact. When the scientists installed a video screen close to the rehabilitated primates' habitat, they noticed the facial regions of primates that viewed the footage warm up.

So, in terms of stress, viewing infant primates playing is the inverse of a surprise job interview or an spontaneous calculation test.

Future Applications

Using thermal cameras in ape sanctuaries could demonstrate itself as beneficial in supporting rescued animals to adjust and settle in to a unfamiliar collective and unknown territory.
