Research results that 'heart rate and sweating are synchronized' when you are attracted to the opposite sex

Romantic Attraction Is Linked to Synchronized Heartbeats, Dating Experiment Reveals

While humans often find someone attractive, a research team led by psychologist Eliska Prochazkova at Leiden University in the Netherlands is physically when they find someone attractive. I thought there might be some signs. Therefore, the research team recruited young subjects at various events and conducted experiments to make 'virtual matchmaking'.
A total of 140 heterosexual and single young people were the subjects of the experiment, wearing glasses with a camera that records eye movements and gestures and sensors that measure heart rate and sweating. We faced a virtual matchmaking set by the research team. The flow of the experiment is as follows.
1: Men and women sit at a table where they cannot see each other due to barriers.
2: The barrier opens for a few seconds and looks at each other's faces. Evaluate how attractive your opponent was after the barrier closed.
3: The barrier that separates the two people opens again, and this time they talk freely for a few minutes. Evaluate how attractive your opponent was after the barrier closed.
4: Finally, the barrier opens again and stares at each other for 2 minutes without speaking. Evaluate how attractive your opponent was after the barrier closed.
During a series of matchmaking experiments, the glasses recorded physical cues such as the subject's gaze, facial expressions, and behavior, and the sensors recorded physiological cues such as heart rate and sweating. Generally, it is thought that facial expressions and eye contact suggest whether or not they are attracted to the other party, but when analyzing the data, such results were not obtained.
On the other hand, in subjects who found the other person attractive, the results showed that heart rate and sweating were synchronized with the other person. 'None of the signals (such as facial expressions or eye contact) predicted how much one person was attracted to another,' Prochazkova said. 'It's the heart rate and skin conductance that determine this. It's an invisible internal signal, such as an increase or decrease in sweating. ”“ When I was attracted to the other person on a date, I found that my heart rate was synchronized with the other person. When one heart rate increased, the other increased as well. However, when one's heart rate decreased, the other decreased. Skin conductance followed the same pattern. When two people synchronize at a deep level, it seems that each other's feeling of attraction increases. '
Synchro of heart rate and sweating can be caused by subtle changes in facial expressions that are invisible to the naked eye, Prochazkova said. 'It may be a small blink. Unknowingly perceiving such a subtle change in facial expression makes you feel better when you realize that the person understands you at the emotional level. That will increase your heart rate. This will happen when you find someone in love and charm. '
'Importantly, our findings show that the physiological states of partners interacting in pairs are momentarily synchronized and consistent with each other,' the research team said. Because it was one of the earliest experiments to detect attractiveness through gaze tracking and physiological measurements, we gave researchers who reproduce this result a more controlled experimental environment, specifically I advise you to use a larger sample.
