Story at-a-glance
- Conversing in-person results in strong and complex neural signaling, but this is dramatically reduced when meetings take place virtually, with unknown consequences for the human psyche
- A Yale team used neuroimaging technologies to study interactions between two people in real time, face-to-face as well as conversations on the video conferencing platform Zoom
- Significant differences were found in brain activity, with the strength of neural signaling reduced on Zoom compared to in-person
- Those speaking face-to-face had increased gaze time and increased pupil diameters, which suggests increased arousal in the brain
- The participants’ brains also had coordinated neural activity in-person, likely due to reciprocal exchanges of social cues that the pair experienced during their face-to-face chat
The use of online video conferencing skyrocketed during the COVID-19 pandemic, likely changing the course of business meetings permanently. But the convenience of online meetings may come at a cost, according to scientists with Yale School of Medicine.1
