Scientists from Yale University discovered that the brain activity of people talking on Zoom is different from people communicating face to face. The research was published in the journal Imaging Neuroscience.
Neuroscientists visualized the brain activity of several pairs of people participating in a live chat and Zoom call during this time. They found that signaling between brain cells was significantly suppressed in Zoom participants.
Increased neural activity during face-to-face communication was associated with more attentive processing of faces: increased pupil diameter and time spent looking at faces. Scientists also found that people’s brain activity is more synchronized when communicating face-to-face. This is probably necessary for better social signal exchange.
“The dynamic and natural social interactions that occur spontaneously during face-to-face interactions are less evident or absent during Zoom meetings. Online images of faces do not have the same “privileged access” to social neural circuits in the brain, at least using current technology, the authors noted.
The scientists concluded that these results show how important face-to-face interaction is for natural social behavior.
