Abstract
Contemporary research found that neural signals tend to synchronize during coordination. This study investigated cognitive processes underlying inter-brain synchrony while coordinating. During a tacit coordination task electroencephalography (EEG) data was simultaneously recorded for paired participants. Their goal was to choose matching images without talking nor seeing each other, only using each other’s choices as feedback. Pairs succeeded in matching more often than shuffled participants. Moreover, participants learned to coordinate better over time. Namely, matching performance increased significantly over trials. Successful coordination requires thinking about each other’s beliefs and intentions (theory of mind; ToM). Therefore, it was hypothesized that inter-brain synchrony in the alpha band (9-14 Hz) reflected ToM processing. Overlapping attentional resources with working memory might impair ToM processing. Consequently, it was expected that coordination and synchrony decrease with higher working memory load. In this study a high load n-back task decreased coordination performance, but not inter-brain synchrony. Due to limited EEG (one session) and behavioral (four sessions) data, results should be interpreted lightly. However, coordination performance and right parieto-occipital phase locked inter-brain synchrony might be related. This regional synchrony potentially reflects that people learn to attend and integrate similar stimulus features in order to coordinate.
