Interpersonal EEG synchrony while listening to a story recorded using consumer-grade EEG devices

Abstract

Interpersonal EEG synchrony derived from the hyperscanning technique has the potential to reveal brain mechanisms beyond the border of traditional analysis within an individual subject. However, the inter-brain connectivity has not been fully investigated using wearable consumer-grade EEG devices which can enable a variety of application in a real-world scenario. In this study, we investigate interpersonal synchrony by capturing EEG signals using wearable EEG devices, from multiple participants (N = 6, 7, 15) who simultaneously listened to a novel being read to them. The results show that similar power-spectral patterns from neural responses evoked by perceiving the same auditory stimuli exhibit the synchrony, which is likely to have a transient characteristic rather than being stationary.
