German scientists have established this notion. - This stance suggests tension.
A team at the University of Erlangen-Nuremberg has found a way to determine a person's stress level through artificial intelligence, without the need for blood or saliva samples.
Uncovering the Stress Posture
Dr. Robert Richter and his team attached acceleration sensors onto the bodies of several participants. For the experiment, the participants were required to undergo two simulated job interviews and were given math problems to solve. In one scenario, the examiners provided a friendly and supportive response. In the other, they remained unresponsive, creating a stressful environment.
After analyzing the movement data from these runs, researchers identified stress-related patterns in posture. By using this data, an adaptive algorithm was fed, enabling it to accurately identify stressed individuals.
Freezing Under Pressure
The artificial intelligence correctly assessed around 75% of the participants and differentiated between those who were stressed and those who were not. Researchers discovered that stressed participants moved less or even froze completely over an extended period. They would also clasp their hands in front of their bodies or stand up straight without shifting their weight or moving.
"Although a person who typically moves more may seem calmer in such a situation, they may have a wider range of motion compared to someone who usually moves less, the adjustments in movement caused by stress are highly individual," says Richter.
The group believes this method could offer valuable insights into stress and possibly help to lessen its impact. Rohleder, the senior author, explains, "The growing burden of stress in society is evident in healthcare costs and an increase in workplace absences. We hope our new approach can contribute to better understanding and mitigating stress."
