Summary
Mutual gaze enhances remote joint attention efficiency. Interbrain synchrony (IBS) in frontal and temporal regions varied by interaction mode, revealing neurological insights for online communication.
Area of Science:
- Neuroscience
- Human-Computer Interaction
- Social Psychology
Background:
- Mutual gaze is crucial for in-person social interaction and attention sharing.
- Remote communication necessitates understanding how to establish mutual gaze and brain synchronization online.
Purpose of the Study:
- Investigate the impact of pseudo-mutual gaze on remote joint attention.
- Examine interbrain synchrony (IBS) during remote dyadic interactions.
Main Methods:
- Utilized eye trackers to create a pseudo-mutual gaze channel.
- Employed electroencephalographic (EEG) hyperscanning to record simultaneous brain activity.
- Assessed joint attention tasks in player-observer, collaborative, and competitive modes.
Main Results:
- Mutual gaze improved remote joint attention efficiency.
- Phase locking value estimated IBS, showing low-frequency couplings in frontal and temporal regions.
- Interaction mode influenced IBS, but dyadic gender did not.
Conclusions:
- Pseudo-mutual gaze facilitates neurological synchrony in remote interactions.
- Findings offer insights into brain mechanisms for effective online communication environments.
