New Study Suggests That Heart Rate Synchronization Pupil Diameter And Skin Conductance Are Major Influences In Social Interactions

In Education

You are more likely to be attracted to be attracted to or trust someone if your heart rate and pupil diameter are in sync according to a study conducted by a researcher called Eliska Prochazkova.

Eliska’s research focused on social interactions and the observable aspects that contribute to whether two people can trust each other or even be attracted to each other. She was particularly interested in autonomic mimicry which entails non-visible and non-verbal responses such as pupil dilation, skin conductance and even heartbeat. The study findings indicate that those aspects are indeed important in social settings.

There has previously been a lot of contention over whether autonomic mimicry is the genesis of emotions such as attraction and trust or whether it is caused by those emotions. Prochazkova suggests that autonomic mimicry extend to how our brains understand and process emotions, thus leading to emotional, physiological and behavioral synchronization.

The researcher carried out various experiments including a trust experiment where subjects interacted with a computer simulation for a trust game. The subject trusted the computer when the simulated pupils in the computer had large pupils and the subject also mimicked the pupils. The subject trusted the simulation less when smaller pupils were presented.

Eliska also conducted another study to evaluate synchronization. The test involved speed dating and subjects’ heart rates were monitored. The researcher observed that subjects who felt attracted and aroused by their partners demonstrated higher heart rate synchronization.

The study data certainly indicates that heart beat synchronization, pupil diameter size do make an impact in attraction and trust. However, using them at will to try and manipulate the outcome of a date might not be possible because changing pupil size at will is not possible. Similarly, getting your heart beat to synchronize with the heartbeat of a crush is not exactly in the alleyway of easy feats to pull off.

Prochazkova plans to continue conducting research onto areas such as autonomic mimicry and the underlying mechanisms. However, she is currently conducting research on behavioral training for Czech and Dutch police officers through VR simulations. The training will allow the officers to learn how to handle stressful situations.
