Editorial: Harnessing physiological synchronization and hyperscanning to enhance collaboration and communication

Research on physiological synchronization and hyperscanning is progressing at a rapid pace, with new methods and application areas constantly appearing. In general, physiological synchronization can occur in diverse social interaction scenarios—collaboration, communication, or competition within dyads or larger groups. The degree of synchronization is visible in amplitudes and phases of physiological signals at different granularity levels and can be measured and quantified nearly in real time. Furthermore, taking interpersonal differences into account is critically important in order to accurately measure physiological synchronization and capture its dynamic patterns. Moreover, combining information from multiple modalities (e.g., EEG and autonomic nervous system responses) seems to be a promising approach to synchronization estimation.
